1.1 Using the Mobile Panel 277F IWLAN
Use
The Mobile Panel 277F IWLAN offers the possibility of having the mobile safety functions of
emergency stop and enable available at any point of a machine or plant. An effective range
limit has been implemented for the Mobile Panel 277F IWLAN. Depending on his location,
the operator obtains a safe, electronically monitored operator control enable.
The HMI device communicates with an access point via WLAN. Thus the operator can
operate the various machines or process cells without bothersome cable. The HMI device is
connected via the access point with a PROFINET network in which it communicates with an
F-CPU via the PROFIsafe protocol.

① Access point is the network transition from WLAN to LAN
② WLAN area in which communication with the access point is possible
③ Mobile panel in the WLAN area; the emergency stop button is active, the enabling buttons are
without function.
When the PROFIsafe communication between the controller and operator panel is
established in the WLAN area, the emergency stop button on the HMI device becomes
active.
Safe operation of the plant with the enabling buttons only becomes possible when the HMI
device is logged on in an effective range within the WLAN area.

Effective range
An effective range is the range in which sections of the plant, e.g. a machine can be
operated with the enabling buttons of the HMI device. An effective range is formed physically
with transponders that are mounted in the vicinity of the machine. Each transponder has a
unique ID. The transponder emits this ID in a lobe-shaped area. The ID is received by the
HMI device, which enables the HMI device to determine its distance from the transponder.
Additional information about the transponders is provided in the chapter Planning effective
ranges (Page 46) and in the operating instructions for the HMI device.
352),VDIH
① Effective range 1, formed by a transponder
② Effective range 2, formed by two transponders
③ The mobile panel is located in effective range 3. The emergency stop button is active The
enabling buttons are active after logon in the effective range.
When the HMI device detects that it is within an effective range the operator can log the HMI
device on at the effective range. Safe operation of the plant unit delimited by the effective
range is only possible after successful connection.
Effective ranges should not overlap.
All effective ranges available in the plant are stored in the project. The effective ranges are
verified in the acceptance procedure for the plant.

Note
In addition to the effective ranges you can define zones in your project. The zones are not
relevant for fail-safe operation. They are used merely to control the project depending on the
location of the operator. For example a picture change can be configured for zone entry or
zone exit.
Zones and effective range are independent of each other.
Additional information on zones is provided in the Operating instructions for the HMI device.
Distance measurement between HMI device and transponder
The transmitting range of the transponder and the receiving range of the HMI device have
the approximate shape of a lobe with a range of approximately 8 m.
The detailed representation of the radiation characteristics of HMI device and transponder is
provided in the appendix of the Operating instructions.
A distance measurement between HMI device and transponder is only possible if both
devices are in range of each other. The following table shows when a distance measurement
is successful.

1.3 Switch-off behavior
Fail-safe operation of the Mobile Panel 277F IWLAN
16 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
1.3 Switch-off behavior
Introduction
Different switch-off behavior is possible depending on the situation in the plant:
● Emergency stop
● Shutdown
● Local rampdown.
● Global rampdown
Plant switch-off differs in its triggers and effects.
DANGER
No switch off triggering
In the plant the described switch-off behavior is only triggered if the F-CPU has been
programmed accordingly.
Emergency stop
The operator triggers the emergency stop by pressing the emergency stop button.
Emergency stop is a procedure in response to an emergency that is intended to stop a
process or movement that could result in danger (from EN 60204-1 Appendix D).
The emergency stop immediately stops all machines that are assigned to the F-CPU via the
safety program.
The emergency stop depends on the effective ranges.
The emergency stop button is always active if there is PROFIsafe communication between
HMI device and F-CPU, i.e. if the HMI device is integrated in the PROFIsafe communication.
Shutdown
Shutdown is triggered if the F-CPU detects a communication error on an HMI device which is
logged on in the effective range.
Shutdown is the immediate stopping of the machines which belong to the effective range.
The shutdown is always specific to the effective range.
Local rampdown.
Local rampdown is triggered if the HMI device is logged on at the effective range and if it is
removed from the effective range for longer than 30 seconds.
Local rampdown is the defined shutdown of the machines belonging to the effective range
within a defined time period.
Local rampdown is always specific to the effective range.

1.3 Switch-off behavior
Fail-safe operation of the Mobile Panel 277F IWLAN
Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 17
Global rampdown
Global rampdown is triggered if the F-CPU detects a communication error on an HMI device
which is integrated in the PROFIsafe communication.
Global rampdown is the defined shutdown of the machines assigned in the safety program
within a defined time period.
Global rampdown is independent of the effective ranges.
In the safety program of the F-CPU, ensure that global rampdown is available in the event
that a communication error occurs on an HMI device which is integrated in the PROFIsafe
communication.
Trigger
The switch off can have the following triggers:
● The operator presses the emergency stop button.
● A communication error occurs.
● Timeout: The HMI device is logged on at the effective range and the operator leaves the
effective range with his HMI device for longer than 30 seconds.
Triggering the switch off
The following table shows the effect of the different triggers depending on the operating
situation:

1.4 Integration and segregation
Fail-safe operation of the Mobile Panel 277F IWLAN
18 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
1.4 Integration and segregation
Introduction
In fail-safe operation a safety program runs in the F-CPU. This safety program
communicates with the HMI device. The F-CPU monitors this communication for errors and
analyzes the signals. The terms "integrate" and "segregate" refer to the integration and
segregation of the HMI device in/from the safety program of the F-CPU.
Integrate
If the HMI device is configured for the safety program then when the HMI device starts it is
automatically integrated in the safety program. The integration process is concluded as soon
as the LED"SAFE" is illuminated.
The emergency stop button is active as soon as the HMI device is integrated.
Segregation
Segregation means the desired segregation of the HMI device from the safety program.
The operator has the following alternatives for segregating the HMI device:
● The operator terminates the project.
● The operator presses the ON/OFF button for longer than 4 seconds. After the
segregation process the HMI device switches off.
When the operator segregates the HMI device there are no side effects, e.g. a global
rampdown. When the segregation process is terminated the LED "SAFE" and the
emergency stop button are no longer active.

1.5 Log on and log off at the effective range
Fail-safe operation of the Mobile Panel 277F IWLAN
Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 19
1.5 Log on and log off at the effective range
Introduction
An effective range is the range within which plant units, e.g. a machine, can be operated with
the enabling buttons of the HMI device. The prerequisite for this is that the operator must log
the HMI device on at the effective range.
Logging on at the effective range
If the operator enters an effective range with the HMI device the system shows that he can
log the HMI device on at the effective range via the "Effective range name" object.
To log on he touches the "Effective range name" object. Then he reads the effective range
ID in the plant and enters this ID in the ""Effective range logon" dialog box.
If the entered effective range ID agrees with the configured ID then the HMI device is logged
on.
When the HMI device is logged on the enabling buttons are active.
The system alerts the operator that the HMI device is logged on at the effective range in the
following manner:
● The LED "RNG" is illuminated.
● The "Effective range name" object is displayed in green.
● In the process cell the indicator for the effective range is active, e.g. a lamp.
When the HMI device is logged on at the effective range the following rules apply:
● The operator should not leave the effective range without logging off. Local rampdown
occurs if the operator leaves the effective range for longer than 30 seconds without
logging off.
● No other HMI device can log on at this effective range.
Log off at the effective range
Before the operator exits the effective range at which the HMI device is logged on, he must
log off from the effective range. To log off he touches the "Effective range name" object and
edits the dialog box ""Effective range logoff".
When the HMI device is logged off the enabling buttons are no longer active. The

Due to its position, the emergency stop button is equally accessible for both left-handed and
right-handed individuals.
Due to its profiled design, the emergency stop button is easily accessible. A collared
enclosure is used to protect the operator controls against damage. This applies in particular
to the emergency stop button The emergency stop button may still trigger if the HMI device
falls and hits the floor.
Operation
The operator triggers the emergency stop by pressing the emergency stop button. The
emergency stop button engages in the emergency stop position.
Releasing the emergency stop button
WARNING
If you have activated the emergency stop button and thereby brought the configured
system to a standstill, the emergency stop button should only be released under the
following conditions:
• The reasons for the emergency stop have been eliminated.
• A safe restart is possible.
• The restart should not be executed by releasing the emergency stop button.
The operator must strictly ensure that he executes a separate operator action to
commence the restart. The safety program must ensure that release of the emergency
stop button alone does not trigger an automatic restart of the system.
In order to release the emergency stop button, turn it in a clockwise direction. The
emergency stop button then returns on its own to the initial position.

1.6.2 Enabling button
Introduction
The enabling device consists of the two enabling buttons mounted on both sides of the
Mobile Panel 277F IWLAN. The switch setting of the two enabling buttons is determined by
electrical momentary contact switches.
Note
The HMI device analyzes the switch settings of the two enabling buttons in the form of an
OR gate.
① Enabling button
Operation
WARNING
Unintentional enabling
Press the enabling button only until the operation you wish to enable is completed.
Enabling is a conscious operator action. It is not permissible to continuously press the
enabling button or to fix it in any way.
The following happens if you leave the effective range for a period of up to 30 seconds with
the enabling button pressed: Enabling is revoked 5 seconds after leaving the effective
range.
If you reenter the effective range within 30 seconds, you must release the enabling button
and press it again for enabling to take effect again.
The enabling button has three switch settings:
● Neutral position: The enabling button is not pressed.
● Enable: The enabling button is pressed to a mid position. This switch setting is used to
allow another command, for example an input with the membrane keyboard.

Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 23
● Panic: The "Panic" switch setting is reached as soon as one of the two enabling buttons
is fully pressed. The switch setting of the other enabling button is unimportant in this
case. The "Panic" switch setting has the same effect as releasing the enabling button,
namely, it revokes the enable.
You only have to activate one enabling button. The PLC gets the same signal regardless as
to whether one or two enabling buttons of the Mobile Panel 277F IWLAN have been
pressed.
Note
The enabling button and the membrane keyboard can be operated at the same time.
When using the enabling button the following F FBs must be linked in the safety program of
the F CPU:
● F_FB_MP
● F_FB_RNG_n

1.7 "Override" mode
Fail-safe operation of the Mobile Panel 277F IWLAN
24 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
1.7 "Override" mode
Introduction
The effective range functionality of the HMI device can be extended through the "override"
mode.
Applications
"Override" mode can be used in the following cases:
● Use of existing protective measures instead of the effective range functionality
If protective measures, such as protective fences are already available in your plant, then
you can integrate them in your safety concept with the "override" mode. Thus you achieve
a consistent concept for safe plant operation.
● If plant units, which do not allow themselves transponder coverage, (such as inside a
robot cell), will be operated with the enabling buttons.
In this case you must secure the plant area with additional protective measures, such as
a protective fence.
Requirements
Only use "override" mode in delimited plant units that are secured by additional protective
measures.
Entering and leaving the protected area must be monitored by the F-CPU.
The operator must be able to fully see the area for which "override" mode applies. The
danger location must be visible from every point of the override area.
When using the "override" mode you must install a switch within an effective range that is
independent of the HMI device. The operator activates "override" mode with this switch.
WARNING
Inadmissible activation of the "override" mode
The operator has to activate "override" mode through a conscious operator action, e.g. by
activating a switch. The "override" mode should not be automatically activated, e.g. when
the safety area is entered.
The application program in conjunction with F-FB must ensure that the "override" mode is
revoked when the area is left.

Activation of the "override" mode
The operator activates "Override" mode in the following manner:
1. The operator enters the protected area through a light barrier or across a foot grating.
The protective device is activated.
2. The operator logs on at the effective range in which the override switch is located.
3. The operator activates the override switch.
"Override" mode is now active until either the operator deactivates "Override" mode with the
override switch or until he leaves the protected area.

Operating principle
In the following figure you see the plant area for which "override" mode is active.
352),VDIH
If "override" mode is activated the operator can safely operate the associated plant area with
the enabling buttons. The HMI device is considered to be permanently logged on in the
effective range, without analyzing the transponder signals.
Deactivation of "override" mode
The operator deactivates "override" mode in the following manner:
1. The operator activates the override switch.
"Override" mode is deactivated by the safety program.
2. The operator logs off from the effective range.
Subsequent logon at this effective range is only possible if the operator has terminated
"override" mode with the override switch.
3. The operator leaves the protected area.
If the operator leaves the protected area without deactivating "override" mode, "override"
mode is deactivated by the safety program.

2.8 Safety functions of the enabling button
Introduction
The enabling mechanism is comprised of two enabling buttons mounted on both sides of the
HMI device.
Numerically controlled machines and systems are equipped with the operating modes
"Automatic mode" and "Special mode".
Safety is ensured in automatic mode by means of closed, isolating protective devices and/or
with functional non-isolating protective devices that block access.
In special mode, safety has to be ensured in a different manner than in automatic mode. In
special mode, the danger zones of the machine or system are entered, where controlled
movements have to be possible.
Special mode
A reduced speed on the machine or in the system has to be specified for special mode
based on the risk assessment. Movement of the machine should only be possible when the
enabling device is activated. The operator must have the necessary qualifications and be
acquainted with the details of the intended application.
Safety instructions
The safety-related aspects of the velocity reduction control and those for the enabling device
are designed in such a way that they satisfy the EN 954-1 safety category determined by the
risk analysis.
The operating principles of enabling devices are described in EN 60204. Through the
findings from accident investigations and the existence of technical solutions, the 3-stage
enabling button became state of the art. Positions 1 and 3 of the enabling button are Off
functions. Only the middle position allows the enabling function. EN 60204-1:1997 is
identical to IEC 60204-1, whereby the 3-stage enabling button is gaining international
importance.

Fail-safe operation of the Mobile Panel 277F IWLAN
40 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
The Stop category of the enabling device must be selected on the basis of a risk assessment
and correspond to a Category 0 or 1 Stop.
WARNING
Injury or material damage
Enabling buttons should only be used when the following applies for the person activating
the enabling button:
• The person can see the danger zone.
• The person is capable of recognizing personal injury hazards in good time.
• The person is capable of taking immediate measures to avoid danger.
The only person allowed to remain in the danger zone is the person who is activating the
enabling button.
Commands for unsafe conditions are not permitted to be issued with one enabling button
alone. For this purpose, a secondary, intentional start command by means of a button on
the Mobile Panel 277F IWLAN is required.
The following happens if you leave the effective range for a period of up to 30 seconds with
the enabling button pressed: Enabling is revoked 5 seconds after leaving the effective
range.
If you reenter the effective range within 30 seconds, you must release the enabling button
and press it again for enabling to take effect again.
NOTICE
Enabling button not effective
The enabling button is only effective if the HMI device is logged on in the effective range
and the "RNG" LED on the HMI device lights up.
If the operator leaves the effective range, the enabling button is deactivated after 5
seconds. The "Exit effective range without logoff" dialog opens after 30 seconds. The
"RNG" LED only goes off when the operator confirms this dialog.
Risk from improper use
To avoid the danger of unauthorized use of the enabling button due to impermissible hold-
down, on each project start the enabling button must be pressed all the way down, and then
released.

3.4 Planning effective ranges
Effective range and transponder
An effective range is physically formed by transponders mounted in the vicinity of the
machine. Each transponder sends a unique ID. The ID is received by the HMI device and
enables it to determine its distance from the transponder. If the HMI device is within the
effective range, safe operation is possible once it logs on in the effective range.
Rules for effective ranges
The following rules apply when defining effective ranges:
Rule Explanation
The maximum distance from the transponder
to the HMI device can be 8 meters.
No minimum distance to the transponder can
be configured, but this is always a percent of
the configured maximum range. The following
section provides a detailed description.
System limits
The effective range must be scaled so that the
danger point can be seen from every angle of
the effective range.
Too great a distance or a cluttered effective range
prevents visual control on the part of the operator.
The distance between the machine to be
operated and the operator needs to be scaled
according to the machine.
Insufficient distance from the machine increases the
injury hazard for the user.
Too great a distance from the machine prevents
visual control on the part of the operator.
Machine, transponder and operator position
need to be adapted to one another.
The HMI device needs to be able to measure the
distance to the transponder during operation. The
requires the HMI device to aligned with the
transponder. The operator needs visual contact to
the machine at the same time.
Effective ranges should not overlap.
Consequently you should only assign each
transponder to a single effective range.
Transponders in different effective ranges
must be far enough away from each other that
their transmission ranges do not overlap.
Assignment of effective range to the machine that
will be operated must be unique.
You can set up a maximum of 127 effective
ranges in a project.
System limits
A maximum of 127 transponders can be
assigned to one effective range.

Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 47
Distance measurement between HMI device and transponder
The transponder transmits its ID in lobe-shaped area with a maximum range of approx. 8
meters. The following example shows the varying quality of the effective range based on a
configuration in which a maximum range of x1 = 8 m has been specified.
[
[
[
[
[
\
① Zone with poor quality effective range
② Zone with good quality effective range
③ The effective range quality along the line is 100%.
The effective range quality is best in the middle of the lobe-shaped area: the effective range
quality along the white line is 100%. The effective range quality decreases along the lobe's
center line in the direction of each edge.
There is a zone of poor quality effective range (marked yellow) both directly at the
transponder as well as at the other end of the lobe. At the long side of the lobe there is a
direct transition of the effective range quality from "good" to "no effective range detected".
You can find an exact description of the radiant characteristics of the HMI device and
transponder in specifications section of the operating instructions.
Transponders must be mounted in the system in such a manner that the planned effective
range is covered by the transmitting range of the transponders assigned to it.

3.4 Planning effective ranges
Fail-safe operation of the Mobile Panel 277F IWLAN
48 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
Example:
① Machine that will be operated from within the effective range
② Transponder with transmitting range in the form of a lobe
③ Planned effective range; safe operation of the machine is possible from here
④ Actual effective range; safe operation of the machine is still possible from here
Procedure
1. On the system plan specify which parts of the system will be operated with the enabling
buttons. You require effective ranges for these areas of the system.
2. Specify the spatial expansion of the individual effective ranges. The operator must be
located within the limits of the respective effective range in order to operate the
corresponding plant unit with the enabling buttons.
Comply with the rules for the definition of effective ranges.
3. Plan the transponders in the effective range in such a manner that the effective range is
covered by the radiated emission of the transponders. Ensure that the effective range is
not too large to be seen or another danger arises.
4. Specify the following:
– A name and an ID unique throughout the plant for each effective range from the value
range 1 to 127
– A name and an ID unique throughout the plant for each transponder from the value
range 1 to 65534
– For each effective range the maximum distance that the HMI device can have to the
transponders of this effective range. The distance must be the same for all
transponders of an effective range.
– The mounting location for an indicator.
WARNING
An indicator in the effective range is an absolute necessity
A indicator supplies the operator the feedback that he has logged onto the correct
effective range.
Install an indicator in every situation, for example a light that shows that an HMI
device is logged on in the effective range.
5. On the system plan, note the names and the IDs that you use during commissioning.
Prior to commissioning you must affix the IDs of the effective ranges in the plant so that
they are easily legible.

Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 49
3.5 For the "Override" mode: Planning the protective devices
Introduction
Use "override" mode to extend the effective range concept.
Requirements
Only use "override" mode in delimited plant areas that are secured by additional protective
measures.
The operator must be able to fully see the area for which "override" mode applies. The
danger location must be visible from every point of the override area.
When using the "override" mode you must install a switch within an effective range that is
independent of the HMI device.
The operator logs his HMI device on at the effective range and activates "override" mode
with this switch.
Suitable additional protective measures
When using "override mode you must provide additional protective measures in your plant
which prevent unauthorized use or incorrect operation of the HMI device. The additional
protective measures must have a safety category that is commensurate with the plant
requirements.
For example the following measures are suitable:
● Grate with protective door
● Light barrier
● Foot grating / safety shutdown mat
● Additional plant-typical safety measures
If you use a grating with a protective door, you have to protect against access to the override
area using a further protective measure, e.g a light barrier or a foot grating. This enables you
to leave the protective door open as an escape route during operation of the plant in
"override" mode.
Safety program
The "override" mode may only be activated as long as the safety measure is active.
If the operator leaves the protected area, the "override" mode must be automatically ended.

3.6 Check list: Data security
Introduction
Data security, security in automation technology serves particularly to ensure the availability
and trouble-free operation of industrial plants.
In order to ensure secure transmission of signals via a WLAN for the Mobile Panel
277F IWLAN, you must particularly safeguard the system from unauthorized access.
You can count on the following types of unauthorized accesses:
● Outside accesses
To protect against unauthorized accesses from outside you must protect the WLAN in the
same way you would protect a WLAN for office communication, namely with a firewall.
● Accesses from inside
Investigations have shown that the majority of attacks on data security are executed from
inside the plant. To ensure data security you must take special measures inside the plant.
Possible attack objectives
The HMI device communicates with the fail-safe controller via PROFIsafe. Here the following
possible attack objectives are present:
● Parameter assignment and configuration
Possible objectives of an attack are assignment of parameters to a device and
configuration.
● Productive operation data
The productive data can be manipulated by sending a series of false PROFIsafe
telegrams, which prevent the machine from being switched off.
Data transfer between HMI device and access point is protected by the AES encryption
mechanism. Manipulation of productive data is prevented in this manner.
Organizational measures to ensure data security
The organizational measures to ensure data security are described in the following
documents:
● PROFIsafe – Profile for Safety Technology on PROFIBUS DP and PROFINET IO
(IEC 61784-3-3)
● PROFIsafe - Environmental Requirements
Note the regulations in these documents.
Check list
The following check list shows the organizational measures required to achieve the highest
possible level of data security when transmitting via WLAN.
Specify the organizational measures you must implement in accordance with your plant's
requirements. Take all phases into account:

The address is assigned automatically. The "F_Dest_Add" parameter
can have a value between 1 and 65534.
You can change the value for "F_Dest_Add".
F_WD_Time (ms) Monitoring time in the fail-safe IO device.
A valid current safety frame must reach the F-CPU and be returned to
the HMI device within the monitoring time period. This ensures that
failures and errors are detected and appropriate responses, which
keep the fail-safe system in a safe state or transfer it to a safe state,
are triggered.
The monitoring time selected must be long enough that message
frame delays will be tolerated by the communication system, but short
enough that the fault reaction function responds quickly enough in the
event of a fault (e.g. interruption in the communication connection).
The "F_WD_Time" parameter can be set in 1 ms increments. The
default monitoring time is 500 ms.
Calculate the minimum monitoring time with the Excel table
"s7fcotia.xls".
This table is part of the option package S7 Distributed Safety. You
can find the current version of this table on the Internet at the
following address:
"http://www.siemens.de/automation/support", document ID 21627074.
You can find the parameters needed to calculate the monitoring time
under "General specifications".
NOTICE
If an error occurs, the monitoring time is included in the maximum response time. The
selected monitoring time must be short enough that the error tolerance time of the process
is not exceeded.

4.4 S7 Distributed Safety
Introduction
The Mobile Panel 277F IWLAN is used as a peripheral in fail-safe automation systems. Fail-
safe automation system, also referred to as F systems in the following, are used in plants
requiring high levels of safety.
During fail-safe operation, a safety program runs in the F CPU. The HMI device must be
integrated into this safety program.
The HMI device and F CPU communicate via PROFINET IO. They use the safety-related
PROFIsafe protocol as of V 2.0 for fail-safe communication.
Safety-related functions of the HMI device
The fail-safe HMI device performs the following:
● Detects the signal states of the emergency stop button and enabling button
● Sends these signal states to the F CPU in the form of safety message frames
Safety program and F FBs
To operate the HMI device, you need to configure a safety program in STEP 7 with the
"SIMATIC S7 Distributed Safety" add-on package as of V5.4 SP3.
To guarantee availability of the safety functions, you need to use particular fail-safe function
blocks (F FBs) in the safety program.
If you do not use the fail-safe function blocks, the HMI device cannot be integrated in the
safety program of the F CPU. The project on the HMI device cannot be started.
The F FBs are supplied on a CD together with the HMI device.
You can also obtain the F FBs in the Internet at the following address:
"http://www.siemens.de/automation/support"

4.4.2 Using F-FBs
Required F FBs
You must integrate the following fail-safe blocks in your safety program:
● For each HMI device: An F_FB_MP
The assigned HMI device is monitored by this F FB.
● For each effective range: An F_FB_RNG_4 or alternatively an F_FB_RNG_16
The assigned effective range is managed by this F FB.
The number of HMI devices that should get permission to log onto the effective range
determines the F FB that is called, F_FB_RNG_4 or F_FB_RNG_16:
– F_FB_RNG_4 For a maximum of 4 HMI devices
– F_FB_RNG_16 For a maximum of 16 HMI devices
● An F_DB_STATES with a WORD data type or a comparable address area in an available
F DB
Using this F DB, data is exchanged between the F_FB_MP of the HMI deice and
F_FB_RNG_n of the effective range.
● FB 215: F_ESTOP1; with this block, you can ensure that the operator must first provide
confirmation after an emergency stop before the plant can be restarted. You can find this
block in the Distributed Safety F library in the F Application Blocks block container.
● FC 176: F_BO_W and FC 177: F_W_BO
Insert the FC 176: F_BO_W and FC 177: F_W_BO blocks into your safety program since
these blocks are used as calls. You can find these blocks in the Distributed Safety F
library in the F Application Blocks block container.
WARNING
Defective fail-safe application blocks
Do not change the numbers of F application blocks!
Ensure the following matches when changing the names of F application blocks:
• The symbolic name in the symbol table
• The name in the object properties of the block (header)

Rules for the safety program
WARNING
Emergency stop button not evaluated
The emergency stop button can only be evaluated if you call an F_FB_RNG_n in your
safety program.
Always call an F_FB_RNG_n in your safety program, even if you do not use effective
ranges in your plant.
WARNING
Prohibited restart of the plant
Once the emergency stop button has been triggered, the plant can only be restarted for
operation only after the operator provides acknowledgment. Use the FB 215 F_ESTOP1 in
your safety program to ensure acknowledgment by the operator.
WARNING
Emergency stop button evaluation delayed
If the cycle time for OB 35 is set too high, message frame may be lost and the evaluation of
the "E-STOP" of F_FB_RNG_n may be delayed.
Set the cycle time for OB 35 lower than that for the PROFINET IO time.
CAUTION
Safety states not evaluated
The safety states, such as a global rampdown, can only be evaluated if you call an
F_FB_RNG_n in your safety program.
Always call an F_FB_RNG_n in your safety program, even if you do not use effective
ranges in your plant.
WARNING
Emergency stop button enabled
If a global rampdown has been triggered by a communication error, the emergency stop will
no longer be available on the Mobile Panel in question.
You have the option of configuring the "Global rampdown" signal to trigger an emergency
stop.
The F FBs used are called cyclically and in a specific order in the safety program. You need
to call the F FBs in the following order in your safety program:
1. All F_FB_MP
2. All F_FB_RNG_n
The operator must always acknowledge errors, such as communication errors. You cannot
use any automatic acknowledgment in your safety program, therefore.
Configuration

WARNING
Unwanted restart of the plant after acknowledgment of a communication error
The plant cannot be automatically restarted after a communication error on the HMI device
is acknowledged.
Therefore, ensure that your safety program requires an additional user action before the
plant can be restarted.
Interconnection of the F FBs
The blocks are interconnected with one another and with the process image of the Mobile
Panel 277F IWLAN.
For every Mobile Panel 277F IWLAN, there is a memory area in the PLC that is commonly
access by the HMI device and the PLC, the so-called process image. The signal sates of the
HMI device's inputs is sent to the PLC at the start of the cyclic control program through the
process image of the inputs, PII. The process image of the outputs, PIQ, is sent to the HMI
device as the signal state at the end of the cyclic program.
The following figure is a schematic representation of the interconnection of F FBs to one
another and to the PII and PIQ.
WARNING
You cannot directly evaluate the PII and PIQ in your program.

Inputs
Parameters Data type Description Interconnection
QBAD Bool QBAD indicates if the F-I/O has been
passivated.
F-I/O DB:
DBx2.1 = QBAD
ACK_REQ Bool Acknowledgement required
After a communication error, the fail-safe
system sets QBAD = 1 and ACK_REQ = 0.
ACK_REQ = 1 indicates that the PROFIsafe
message frames are being exchanged again.
F-I/O DB:
DBx2.2 = ACK_REQ
S7_MP_RES Bool This input is set so that the F-CPU resets the
status of F_FB_MP to its "original state", i.e.:
• The HMI device has the status "removed"
• If a rampdown or shutdown was set, it is
reset.
• If the HMI device was logged on to an
effective range, it is enabled again.
The input is only evaluated if Q_BAD = 1.
Setting the input S7_MP_RES is necessary if
the HMI device cannot return itself to a
defined state, for example when a system
error occurs or the battery is dead.
Must be specifically
interconnected for
plant.
The security program
must ensure that after
S7_MP_RES is set,
automatic restart of
the plant is not
possible. The operator
must strictly ensure
that he executes a
separate operator
action to commence
the restart.
S7_ACK_ERR Bool Communication errors may not be
acknowledged automatically.
This input is set to have the F-CPU to
acknowledge a communication error during
ongoing PROFIsafe communication.
F_FB_MP only reacts to a rising edge.
Must be specifically
interconnected for

Purpose
The assigned Mobile Panel 277F IWLAN HMI device is monitored by F_FB_MP.
You need to use a separate F_FB_MP for each Mobile Panel 277F IWLAN.
F_FB_MP performs the following tasks:
● The block integrates the HMI device in the safety program of the F-CPU after startup.
● The block removes the HMI device from the safety program after a communication error.
As soon as the communication error has been corrected and the operator has
acknowledged this, the block integrates the HMI device back into the safety program.

● The block passes the states of the HMI device through F_DB_STATES to F_FB_RNG_n.
The following HMI device states are possible:
– "Integrated"
– "Removed"
– "Communication error"
– "Acknowledgement required"
QBAD monitors the output of the F-I/O for integrating and removing the HMI device.
● QBAD = 0: PROFIsafe communication is taking place between the HMI device and the
F-CPU.
● QBAD = 1: No PROFIsafe communication is taking place between the HMI device and
the F-CPU.

Usage
WARNING
Emergency stop button not evaluated
The emergency stop button can only be evaluated if you call an F_FB_RNG_n in your
safety program.
Always call an F_FB_RNG_n in your safety program, even if you do not use effective
ranges in your plant.
The assigned effective range is managed by this F FB.
You need call one of the following F FB for every effective range when using the
Mobile Panel 277F IWLAN:
● F_FB_RNG_4 "Effective range for 4 Mobile Panels"
● F_FB_RNG_16 "Effective range for 16 Mobile Panels"
The FB you need to call depends on how many HMI devices are used in the effective range:
● If you configure a logon for up to 4 HMI devices in this effective range, use F_FB_RNG_4.
● If you configure a logon for up to 16 HMI devices in this effective range, use
F_FB_RNG_16.
How it works
The F FB performs the following depending on the state of the HMI devices assigned to the
effective range:
● Connect the outputs of F_FB_RNG_n
● Prepare the output user data
Each HMI device can take one of the following states in the effective range:
● Removed without communication error
The HMI device is successfully removed from the safety program of the F CPU. This
ends PROFIsafe communication. The HMI device has no influence on the outputs of
F_FB_RNG_n.
● Integrated without communication error

F_FB_RNG_n reacts as follows:
– The HMI device is supplied with user data, such as the effective range ID and the
status of the HMI device in the effective range, if it is located in the effective range.
– If no other HMI device is logged on in the effective range, the operator can log on the
HMI device in the effective range.
– The outputs of F_FB_RNG_n are set according to the state of the enabling button of
the logged on HMI device.
The setting for E-STOP output depends on whether or not the HMI device is logged on
in the effective range.
– The RNG_BUSY output of F_FB_RNG_n is set to "1" if the HMI device is logged on in
the effective range.
– The operator can activate the "Override" mode if needed.
– If the operator wants to exit the effective range, he can log the HMI device off from the
effective range.
● Removed with communication error
PROFIsafe communication with the HMI device was interrupted without explanation.
The following outputs are set in F_FB_RNG_n:
– GLOB_RD, if the HMI device was not logged on in the effective range.
– SHUTDOWN, if the HMI device was logged on in the effective range.
The corresponding signal is reset following acknowledgment of the communication
error or the MP status reset is set. The allocated effective range is enabled again by
F_FB_RNG_n for logging on of an HMI device .
● Integrated with communication error
PROFIsafe communication with the HMI device is resumed after a brief interruption,
enabling user data to be exchanged again between the HMI device and F CPU. As long
as communication error in not acknowledged, F_FB_RNG_n reacts as follows:
– The HMI device is supplied with user data (effective range ID, status of the HMI device
in the effective range), if it is located in the effective range.
– If the emergency stop of the HMI device is pressed, the E_STOP output of
F_FB_RNG_n is set to "0".
Override in the safety program
The override switch should only be active as long as the protective mechanism is active.
Connect the following in the safety program to ensure this reaction:
● The switch position of the override switch with the evaluation signals of the protective
device
● The result of the first link with the OVERRIDE input of F_FB_RNG_n
Addresses of PII and PIQ
You can find the start address of the PII and PIQ AA in HW Config in the PROFIsafe settings
for the HMI device.

4.5.2 Effective ranges editor
Work area
In WinCC flexible ES, open the "Effective Ranges" work area in the project window under
"Device Settings" by double-clicking on "Effective Ranges".
The work area provides a tabular view of the effective ranges and their transponders.
Configuring
The configuration consists of the following tasks:
1. You create the effective ranges by specifying the "Name", "Display name" and "ID".
The "Display name" and "ID" of an effective range cannot be identical.
2. You configure a transponder by specifying the "Name" and "ID" of the transponder.
3. You assign the transponders to the effective ranges.
4. You set the "limit" for each effective range.
The "Limit" parameter determines the maximum distance between the HMI device and
the individual transponders of an effective range. The "Limit" parameter applies to all
transponders of the effective range. If the HMI device is located farther from the
transponders than the "Limit", it is outside the effective range.
Commissioning
When commissioning the plant, you need to enter the checksum determined during the
verification of the effective ranges in the "Checksum" box in this editor.

5.2 Accepting effective ranges and transponders
Introduction
The operational safety of the plant for the most part depends on a good safety plan and a
careful realization of the safety functions.
For safe operation, the project of the HMI device must precisely match the plant.
For this reason when first starting a project in the plant, you must verify all effective ranges
with all transponders. The result of the verification is a CRC checksum that you must enter in
the project. Then you must transfer the project to the HMI device again.
Note
Transponders that are exclusively assigned to one zone are not considered in this
verification.
Acceptance if there are changes
If you change the configuration of transponders and effective ranges in the system, you need
to adapt the configuration. Then you must accept the effective ranges and transponders
again.
Requirement
● In the project:
– Effective ranges and transponders must be configured in the project.
– The project has been transferred to the HMI device.
● In the plant:
– The transponders must be mounted in the plant in such a manner that the effective
ranges stored in the project are formed.
– Batteries must be inserted in the transponders. The ID must be set on the
transponders that is stored in the project for these transponders.
– The IDs of the effective ranges must be marked in the plant.
– The quality of the WLAN range must be sufficient.
– An indicator is installed.
WARNING
An indicator in the effective range is an absolute necessity
A indicator supplies the operator the feedback that he has logged onto the correct
effective range.
Install an indicator in every situation, for example a light that shows that an HMI
device is logged on in the effective range.

Testing the effective ranges in the plant
After successful verification of the transponders and effective ranges you must test in the
plant whether the expansion of the configured effective ranges corresponds to the planning.
In particular, check the following cases:
● Do the limits of the effective range run as planned?
Pay special attention that no machine operations are permitted from excessive distances
or areas that cannot be seen.
● Does the indicator that belongs to the effective range show whether an HMI device is
logged on at the effective range?
● Are moving machine parts influencing the reception of the transponders? Check also the
extreme positions of moving machine parts.
● Is WLAN coverage ensured everywhere in the effective range?

Operation 6
6.1 Organizational measures
The HMI device should only be operated in the system with a battery or in the charging
station.
To ensure fail-safe operation of the HMI device the organizational measures described
below must be complied with.
Storing the HMI device
WARNING
Non-functional emergency stop button
If the HMI device is not integrated, the emergency stop button does not function.
To avoid confusion between effective and non-effective emergency stop buttons, only one
integrated HMI device should be freely accessible.
If the HMI device is not in use, it must be stored in a locked area.
Handling the HMI device during operation
CAUTION
Shutdown or rampdown of the system due to empty battery
An integrated HMI device with flat battery triggers a communication error. This results in the
following reaction of the F CPU:
• If the HMI device is logged on at the effective range: Shutdown
• If the HMI device is not logged on at the effective range: Global rampdown
Check the charge status of the battery of the ready-for-operation device via the "BAT" LED.
• Recharge the HMI device in good time.
To charge the batteries, the ambient temperature / battery temperature must not exceed
40 °C The higher the temperature, the longer it will take for the battery to charge.
Find a place with a cool ambient temperature for the charging station. If necessary,
allow the battery to cool first. You can check the battery temperature in the "OP" dialog
box, "Battery" tab in the Control Panel.
Alternatively, change the main battery.
Operation
6.2 Typical applications

84 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
The following must be noted when working with the Mobile Panel 277F IWLAN:
● Pay attention to the "SAFE" LED.
If the HMI device is integrated in fail-safe communication, the "SAFE" lights up and the
emergency stop button is active.
● Pay attention to the "COM" LED.
If you leave the area with sufficient WLAN coverage, the "COM" LED will flash.
Communication between the HMI device and PLC is down. You can no longer operate
the system with the HMI device.
● Check the "RNG" LED when the HMI device is logged onto the effective range.
The "RNG" LED indicates when the HMI device is logged onto the effective range.
Logging onto the effective range is required for the enabling button to be active.
CAUTION
Unauthorized operation possible
It is not permitted to leave the effective range without an HMI device while the HMI
device is logged on to the effective range.

Application example: Safety Functions A
A.1 Configuration and operation
Introduction
The following example shows a possible application of the safety functions of the
Mobile Panel 277F IWLAN.
Note
This example is restricted exclusively to the typical functionality of the Mobile
Panel 277F IWLAN, in this case to the "override" mode. Additional security measures, e.g.
reducing speeds when opening protective doors, must also be taken into consideration in the
safety program,depending on the plant. These measures are, however, not dependent on
the functionality of the "override" mode.
WARNING
Please also observe the information on S7 Distributed Safety, which you can find in the
programming and operating manual "SIMATIC S7 Distributed Safety - configuring and
programming" and in the online help for S7 Distributed Safety.
Sample configuration
The following sample configuration shows a robot cell which is protected by a protective
fence with a protective door.
To operate the robot in "override" mode, the following components must also be installed:
● A transponder for forming an effective range for the "override" switch. By logging on to
this effective range, the operator is granted the permission to activate the "override"
switch. Without logon to the effective range, activating the "override" switch will have no
effect.
● The "override" switch. When the operator activates the "override" switch after logon to the
relevant effective range, the "override" mode is activated by the positive edge of the
switch.
● A contact mat at the entrance to the protected area. The contact mat enables you to
detect whether the operator is leaving the protected area or whether a second person is
entering the protected area while the "override" mode is active. In these cases the
"override" mode is automatically terminated.
In addition, a lamp is installed, which indicates that the effective range is in use by the
logged on HMI device.
If the "override" mode is active, the operator controls the robot by pressing a function key on
the device and confirming operation with one of the enabling buttons.

3. Open the settings by double-clicking on the F-CPU in the HW Config. You see the most
important settings in the following:
Setting Explanation
Cyclic interrupts:
This is where you set the cycle time
for the OB 35.
Note:
If the cycle time for OB 35 is set too
high, message frames may be
missing and there may be a delay in
evaluating the "E-STOP" output of
the F_FB_RNG_n .
Set the cycle time for OB 35 slower
than the PROFINET IO time.
Protection level:
Assign a password for the safety
program.
Set the "CPU contains safety
program" check box.
All the F-blocks required for the safe
operation of the F-modules will only
be compiled with this setting on
compilation of the HW Config of
STEP 7.

"PROFIsafe" tab.
The table below shows the most important settings:
Setting Explanation
Device name:
Assign a device name to the HMI
device here, which is unique in the
Ethernet subnetwork. This name
must match the name defined in the
Control Panel of the HMI device
under "PROFINET" in the text box
"Device name: (max. 240
characters)".
For detailed information, refer to the
operating instructions of your HMI
device.

120 Function Manual, 08/2008, 6AV6691-1FQ01-2AB0
Setting Explanation
Inputs:
Here, define the starting addresses
of the inputs and the process image
to which this address area belongs
(PII).
Outputs:
Here, define the starting addresses
of the outputs and the process
image to which this address area
belongs (PIQ).
F_Dest_Add:
PROFIsafe address of the Mobile
Panel 277F IWLAN. This address
must match the address on the HMI
device.
F_WD_Time (ms):
Monitoring time in the fail-safe IO
device.
A valid current safety message
frame must reach the F-CPU and be
returned to the HMI device within the
monitoring time period. This ensures
that failures and errors are detected
and appropriate responses, which
keep the fail-safe system in a safe
state or transfer it to a safe state,
are triggered.
The monitoring time selected must
be long enough that message frame
delays will be tolerated by the
communication system, but also that
the fault reaction function responds
quickly enough in the event of a fault
(e.g. interruption in the
communication connection).

Function Manual, 08/2008, 6AV6691-1FQ01-2AB0 121
A.3 Safety program S7 Distributed Safety
Functionality
The safety program of the S7-CPU takes care of the following:
● The "override" mode is started when the Mobile Panel 277F IWLAN is logged on at the
effective range and there is a positive edge on the override switch.
● When the Mobile Panel 277F IWLAN is logged on at the effective range in which the
override switch is located, the signal lamp comes on.
● The "override" mode is terminated if either the override switch is activated again or if the
operator leaves the protected area and steps on the contact mat.
● If the "override" mode is active, the operator can control the robot by pressing a function
key on the device and at the same time confirming operation with the enabling button.
● After an emergency stop, the plant only restarts when the operator has performed an
additional acknowledgment.
● In the event of a rampdown or shutdown, the appropriate plant-specific responses are
initiated.

The activation of the "override" mode is controlled in this network.
"SR_Override" is set if the override switch is switched on, i.e. I11.0 = "1". "SR_Override" is
reset by a negative edge of the contact mat, i.e. I11.1 = "0". This is the case if the operator
leaves the override area without terminating the "override" mode. Only when the
"SR_Override" is set and the override switch is set to "on" is the "override" mode activated
with the F_FB_RNG.
At the same time, the F_FB_RNG monitors the signals "emergency stop", "global
rampdown", "local rampdown" and "shutdown". They are scanned in networks 3 to 6.

In network 3 the emergency stop signal of the HMI device is monitored via the F_ESTOP1
from the F-library of S7 Distributed Safety. The F_ESTOP1 ensures that the plant is only
able to restart following an emergency stop after acknowledgment by the operator via the
input "ACK".

In network 4, 5 and 6 the signals for a global and a local rampdown and shutdown are
processed further. As the configuration of the monitored plant determines which responses
have to occur following occurrence of a particular safety state, these networks are not
explained in detail in this example.
