1-1 DeviceNet Wireless Unit

The DeviceNet wireless unit, consisting of a DeviceNet wireless master sta-

tion and a DeviceNet wireless slave station, allows wireless communication

with the DeviceNet slave.

Basically, the wireless master station is connected to the DeviceNet network

and acts as either a virtual DeviceNet slave or wireless network master station

for the DeviceNet master unit. The wireless slave station acts as either a wire-

less network slave station or a virtual DeviceNet master with the DeviceNet

slave unit.

This unit conforms to the following radio wave standards.

Conformance with these standards means that the antenna can be installed

separately. The unit can be purchased as a set with a pencil antenna (WD30-

ME/-SE) or with a magnet-base antenna (WD30-ME01/-SE01). (The dia-

grams in this manual are for the WD30-ME/-SE.)

Errors can be monitored DeviceNet slave error information (including errors in wireless slave stations)

can be assigned to two or four status words and monitored from the PLC.

Abundant number of

wireless channels allows

the construction of

multiple systems in the

same area

Since the wireless region is divided into 34 frequencies from 2,400 to

2,483.5MHz, you can select an unused frequency for building multiple sys-

tems.

Using a spectral spread method (DS: direct spread) as a modulation method

achieves high-quality communications even in areas of excess noise.

Relay functions make

possible an extension in

communications

distances

Although communications distances vary according to the installation environ-

ment, the goal indoors is 60m in line of sight.

The relay functions allow an increase in the communications area (to a maxi-

mum of 3 stages).

DeviceNet slaves may also be connected to the relay station.

However, relay station system settings can only be performed from the config-

urator.

Diversity functions Multi-pass phasing is improved with a diversity system (which requires 2

antennas).

The effects of this function are observed when used in areas where variations

in radio waves (such as reflections) occur.

Maximum number of I/O

per wireless master

station increased

Depending on the switch settings of the wireless master station, the maximum

number of I/O per wireless master station can be increased to 100 words/

100 words (IN/OUT). The maximum number of wireless slave stations that

can be connected has increased to 64.

Magnet-base antenna

added to lineup Using the magnet-base antenna, the station itself can be installed inside a

control panel with the antenna installed outside. Also, because it is mounted

with a magnet, the position of the antenna can be adjusted easily when, for

example, the control panel is moved. Attenuation in the antenna cable (2m),

however, limits the maximum communications distance to approximately 50m

indoors.

Initializing the wireless

master station When the power supply is turned on, the wireless master station adds each

registered wireless slave station. When wireless communication begins with

an slave station, if the number of I/O points on the DeviceNet slave connected

to the slave station and the I/O points registered for the wireless master sta-

tion are identical, it is added. If they are not identical, an I/O configuration

error will occur.

Processing when an error

occurs Even if an error occurs in the DeviceNet network below a wireless slave sta-

tion after initialization is complete, the wireless network polling communication

will continue as normal. The user should monitor the status at his device

(PLC, computer) when an error occurs, and apply the appropriate error pro-

cessing program for the type of error and the area in which it occurred.

I/O for DeviceNet slaves is allocated in the wireless slave stations by ascend-

ing order of DeviceNet node address without leaving any unused areas, and

then in the wireless master station by ascending order of slave station wire-

less node address (WNODE) without leaving any unused areas.

• The IN and OUT areas are allocated in units of 16 points (1 word). In the

case of 8-point units, the lower byte (bits 0 to 7) is allocated and the upper

byte (bits 8 to 15) is set to 00 Hex.

• The following four types of I/O allocations can be set using the DIP switch.

Confirm this status at the CPU unit, and prepare an error processing program

for sending commands to (Explicit messages) and obtaining detailed status

reports (wireless network status, DeviceNet master status) from wireless

master stations showing error flags. (Refer to SECTION 3 Sample Program.)

Each of the following for the DeviceNet master status of added wireless slave

stations is set to an OR value.

Incorrect switch setting/EEPROM error (bit address 00)

Repetitive node address/Busoff detection (bit address 01)

Configuration error (bit address 03)

Structural error (bit address 04)

Send error (bit address 05)

Communication error (bit address 06)

Verify error (bit address 07)

Also, if a wireless slave station has been registered but not added, the bit will

be 1. For example, if a wireless slave station error occurs for WNODE = 16,

the uppermost bit for "status begin word +0" (16) becomes 1.

Each wireless master station can control a maximum of 512 (or 1,600) I/O points. However, there

are limits to the number of I/O points per node for each master unit. Therefore, systems should

be designed without exceeding the limitations for the number of I/O points per node for each

master unit.

Refer to the "DeviceNet User’s Manual" for details concerning DeviceNet

master status errors.

1-2-5 Disconnect/Connect Switch

The Disconnect/Connect Switch function that was introduced with CS/CJ-

series DeviceNet master units can be used for wireless slave stations. A bit is

allocated to each wireless slave station’s WNODE, and if this bit is turned ON

(1), wireless I/O communications and message communications with the cor-

responding wireless slave station will stop (i.e., the wireless slave station is

disconnected from the network). This function is mainly used to reserve space

for wireless slave stations to be added in the future (i.e., I/O points have been

registered in the wireless master station but no wireless slave station has

been connected yet).

Wireless slave stations that have been disconnected from the network do not

need to be considered when calculating the wireless communications cycle

time.

In the DeviceNet master unit’s I/O area, 0 is set in the IN area allocated to

wireless slave stations that have been set to leave the network.

Basic Functions of the DeviceNet Wireless Unit Section 1-2

1-2-6 DeviceNet node addresses

DeviceNet node addresses (NNODEs) are included in wireless master sta-

tions. The master unit controls the assignment of DeviceNet slave I/O data

registered with wireless slave stations to areas corresponding to these node

addresses.

Wireless node addresses (WNODEs) are included in wireless slave stations.

These node addresses are used for control by wireless master stations.

Therefore, there is no purpose in assigning the wireless slave station

DeviceNet node addresses (NNODEs) to I/O. Normally, a 7 segment LED is

used to display the DeviceNet node address on wireless slave stations.

Since DeviceNet node addresses are controlled by wireless slave stations, be

sure to set the DeviceNet slaves so that there is no redundancy.

1-2-7 DeviceNet wireless unit default setting values

Wireless unit network default settings are on a 1:1:2 structure of wireless

master station: wireless slave station: DeviceNet slave with IN/OUT = 16

points/16 points, as shown in the figure below.

The default settings can be returned to on both wireless master stations and

slave stations using the DIP switches in SET mode. Refer to 2-4 System Initial

Setting and Starting Communications for detailed setting information.

1-2-8 Serial Number Check

With the release of the WD30-ME with Identity Object Revision value 3.02, it

has become possible to register the serial number (the wireless slave station’s

own unique ID) of wireless slave stations to non-volatile memory in the wire-

less master station.

If a wireless slave station is registered to a wireless master station using

switch operations at the wireless master station, or if serial number check is

enabled for the wireless slave station by editing the device parameters using

the configurator, and the serial number is written, the wireless slave station’s

serial number is registered to the wireless master station’s non-volatile mem-

ory.

This function is for preventing incorrect WNODE settings for wireless slave

stations, and communications errors resulting from the effects of intermodula-

tion.

If serial number check is enabled for all the wireless slave stations registered

to a wireless master station, the dot on the right-hand side of the wireless

This is the Windows application that runs the DeviceNet computer master sta-

tion.

Master and slave unit settings can be referenced (slave entry, I/O allocations,

wireless network protocol parameters, commands issued), conditions moni-

tored, used frequency bands (channels) monitored, and running tests per-

formed from the DeviceNet configurator (Ver. 2.0 or later).

1-3-1 Configuration

The computer running the Configurator is connected to the DeviceNet net-

work by installing an OMRON DeviceNet Board in the computer or by con-

necting the computer to a serial communications port (peripheral port) of the

CS1W-DRM21 DeviceNet Unit on a CS1-series PLC.

Note In both cases, the same online functions are supported.

Application Limitations Section 1-4

1-4 Application Limitations

The wireless unit is not designed to be compatible with every type of applica-

tion that uses DeviceNet. Do not use the unit with the following applications.

1,2,3... 1. Applications that require real-time control

Do not use the unit with applications that require real-time control. In par-

ticular, it cannot be used under conditions that require responsiveness

greater than that outlined in "Section 9 Communications Timing".

Applications that do not require real-time control, such as indicators, equip-

ment error monitors, and parts picking operation, are recommended.

2. Applications that use FINS message communications

Wireless units do not support FINS message communications. For exam-

ple, although CX-Programmer Ver. 2.1 and later versions support online

connection (i.e., remote programming and monitoring) to PLCs on De-

viceNet networks (e.g., PLCs with CS/CJ-series DeviceNet Units or pro-

grammable slaves), this functionality is not available via wireless units.

4. Applications that require setting the DeviceNet slave "Communication

Error Output" to "Standby"

When a wireless slave station is reset from some error, it is possible that

the DeviceNet slave output will be momentarily cleared. Therefore, appli-

cations that set the output to "Standby" during communication errors can

not be used.

5. Applications where software reset (Explicit messages) must be performed

for the slave station from the upper DeviceNet network

1-5 Points for Consideration with Wireless Systems

Points for Consideration with Wireless Systems Section 1-5

Setting wireless channels It is necessary to select frequencies for the wireless channels that are not

interfered with by radio waves. (Radio interference can be handled by retry

processes between the wireless networks, but will lengthen the system

response time.)

With this unit, 34 wireless channels can be selected from. Taking the following

points into consideration, however, the maximum number of wireless systems

usable in a single area without radio interference is, as a rough guide, 10.

1. It is possible that, for example, there is a wireless LAN on site that uses the

same frequency as this unit. Select an unused wireless channel using the

Configurator’s wireless channel monitor function.

2. Do not select neighboring wireless channels as they have a large amount

of interference.

3. Due to the fundamental nature of radio waves, if 2 or more waves with dif-

ferent frequencies are output at exactly the same time, mutual interference

will occur between the different frequencies, and new waves will be gener-

ated with frequencies at intervals equal to the intervals between the output

frequencies. (This phenomenon is called “intermodulation.”)

Do not select the frequencies of waves created by intermodulation.

Antenna separation

distance The distance between wireless units has a large influence on the amount of

interference received. In particular, there may often be cases where wireless

master stations are installed relatively closely to each other. Separate the

antennas for different wireless master stations by at least 1 m (at least 2 m, if

possible).

Test confirmation Perform a test to see whether or not the wireless units are receiving interfer-

ence. Using the Configurator’s running test function, obtain the packet error

rate, and, based on this, determine whether or not the communications quality

is sufficient for the application. (As a rough guide, the packet rate should be

less than 0.01.)

Due to the fundamental nature of radio waves, if 2 or more waves with different frequencies are

output at exactly the same time, mutual interference will occur between the different frequencies,

and new waves will be generated with frequencies at intervals equal to the intervals between the

output frequencies.

Points for Consideration with Wireless Systems Section 1-5

!Caution Communications errors caused by intermodulation

Communications errors and retry processing may occur due to intermodula-

tion and consequently cause transmission delays. In order to eliminate the

influence of intermodulation, do not set the wireless channels for wireless

units in every system to frequencies at regular intervals.

Before starting operation of the wireless system using a WD30-ME with Iden-

tity Object Revision value 3.02, either register wireless slave stations to the

wireless master station using switch operations at the wireless master station,

or enable serial number check for the wireless slave stations using the config-

urator, and then register the serial numbers of the wireless slave stations to

the wireless master station by writing the serial numbers.

A single wireless master station is limited to a maximum of 1,024 or 3,200

points, 512 (32 words) or 1,600 (100 words) points each for both IN and OUT.

In addition, the maximum configuration in a wireless network of master sta-

tions to slave stations is 1 to 32 or 1 to 64, and the maximum number of IN/

OUT points for the entire system is limited by the DeviceNet master unit. This

should be considered carefully when determining system configuration.

System configuration

example In this section, the operation procedure is explained using the following sys-

tem configuration as an example.

A communications power supply (Model S82K) has been purposely left out

of the diagram above. It should be connected and supply power to the

DeviceNet network (both upper and lower) and should be connected with ter-

minating resistor. In addition, an external power supply should be connected

to the environment-resistant terminal of the DeviceNet slave.

2-2-2 Confirmation of specifications

Confirmation of number of

IN/OUT points Confirm that the number of IN/OUT points for each wireless master station is

no more than 512 or 1,600 (32 or 100 words).

In the example, the number of IN points is 8 × 4 = 32, and the number of OUT

points is 8 × 2 = 16.

A single wireless master station can control up to 512 points (or 1,600 points) for both input and

output, but the number of I/O points per node is limited by the master unit. Be careful not to

exceed the limit for I/O points per master unit node when constructing your system.

Pre-work Preparations Section 2-2

Confirmation of wiring A special communications cable is required to connect to the DeviceNet

micro-connector on the wireless unit.

In addition, if multiple DeviceNet slaves are connected, branch taps should be

used as necessary. Terminators for the wireless slave station DeviceNet net-

work should also be prepared. Refer to the "DeviceNet User’s Manual" for

details.

Confirmation of

communications power

supply

Since power is supplied to the wireless unit from an external communications

power supply, a communications power connection must be made.

Taking the maximum current at startup into consideration, use a power supply

of at least 350mA. If using an OMRON S82K or S82J switching power supply,

use a model with a capacity of at least 30W (S82K) or 25W (S82J).

tion.

If the same system configuration as for the network default settings (Refer to

1-2 Basic Functions of the DeviceNet Wireless Unit.) is used, there is no need

to do this registration.

The specifics of this example are explained below.

First, begin with the WNODE = 1 wireless slave station.

1. Confirm that the slave station node

address (NNODE) is not doubled

with the DeviceNet slave. In this ex-

ample, NNODE-00 is OK.

2. Check if the communications rate for

the slave station and the DeviceNet

slave is the same. In this example,

since default settings (125kbps) are

used, all of the bits for SW1 should

be OFF.

3. Since the DeviceNet slave is regis-

tered, set SW3 to "bit 6 = ON".

4. Set the mode select switch to "SET".

2-5 Operation Confirmation

The confirmation procedure for whether or not remote I/O communications

are performed correctly is explained in this section.

2-5-1 Unit LED confirmation

If the MS and NS LEDs on all DeviceNet slaves (environment-resistant termi-

nals) light green, the node address is shown on the DeviceNet master

(C200HW-DRM21-V1) LED display (the decimal display disappears), and the

MS and NS LEDs light green, wireless remote I/O communications are oper-

ating correctly in scan list enable mode.

2-5-2 Status confirmation

If the STATUS setting is made, status information is automatically assigned to

the 2 words at the top of the IN area. (The position is fixed.)

The IN/OUT data for DeviceNet slaves (environment-resistant terminals) is

first assigned to the IN areas and OUT areas by the wireless slave stations in

ascending order of WNODE and is then assigned by the wireless master sta-

tions in ascending order of NNODE (1 to 4 in this example).

The IN and OUT areas are allocated in units of 16 points (1 word). Because

the slaves are 8-point units, the lower bytes (bits 0 to 7) are allocated and the

upper bytes (bits 8 to 15) are set to 00 Hex.

5. Set the mode select switch to

"RUN".

6. If all MS and NS LEDs light green

and the node address is shown in

the LED display, the system is in

RUN operation status.

2-7 Deciding the Antenna Installation Position

This unit uses radio waves of frequency 2.4GHz, which is very high. High-fre-

quency waves exhibit strong rectilinear propagation and are reflected easily.

For this reason, careful consideration of the antenna installation position is

required to achieve sufficient wireless performance.

1. If possible, install antennas so that there is a direct line of sight between

them.

High-frequency waves, which exhibit strong rectilinear propagation, are

used and so it is difficult for the waves to reach areas that are not in a direct

line of sight, as shown in the following diagram. This is a particularly impor-

tant point for communications at long distances (e.g., exceeding 50m or

60m.)

If the antennas are installed in locations with relatively high ceilings and a

lot of open space, even if there is no direct line of sight between the anten-

nas, if one of the antennas is installed in a high location, communications

may still be possible via radio waves that are reflected off the ceiling.

2. Install in as high a location as possible.

As mentioned in the preceding paragraph, if the antennas are installed in

high locations, because the space surrounding the antennas will be more

open, there will be less influence from obstacles, and the radio waves will

propagate more easily.

3. Do not place obstacles (especially metal objects) near the antennas.

If there are obstacles near the antennas (in particular, in the direction of

radio wave propagation), the radio waves may not be propagated due to

the influence of the objects. Metal objects have the largest influence as

they reflect radio waves, whereas glass and plastic objects allow the waves

to pass through and so have the smallest influence. Ensure a distance of

at least 30cm between obstacles and antennas.

4. Cable loss in magnet-base antennas

With magnet-base antennas (WD30-ME01/-SE01), there is loss in the 2m

antenna cable. This means that the maximum communications distance is

shorter than with the pencil antennas. As a rough guide, the maximum

communications distance is approximately 50m indoors.

5. Cable bending radius for magnet-base antennas

The minimum bending radius for magnet-base antennas (WD30-ME01/

-SE01) is 38mm. Also, do not bend the cable at points less than 40mm

from the end connected to the station or at points less than 20mm from the

end connected to the antenna.

6. Separate different sets of antennas as much as possible.

If different sets of antennas are close to each other, they will influence each

other and thereby influence wireless communications, causing an increase

in the number of retries and a reduction in the possible communications

distance. Separate different sets of antennas by at least 1m (at least 2m if

possible).

7. Do not install the 2 magnet-base antennas close to each other.

If the 2 antennas are close to each other, the diversity effect will not be uti-

lized. Separate the antennas by at least 62mm (as with pencil antennas).

Magnet-mounting allows the positions to be adjusted easily. If possible,

separate the antennas by a greater distance than this.

8. Install the antennas with the same orientation.

Install antennas that are performing communications with the same orien-

tation, as shown in the following diagram. If they are installed at an angle

of 90° to each other, the possible communications distance will be short-

ened. (In this case, the waves are said to be “polarized.”)

9. Separate the antennas from ID tags by at least 3m.

High antenna

Radio wave energy

Obstacle

Deciding the Antenna Installation Position Section 2-7

The OMRON V690 microwave RF-ID system uses frequencies within the

range used by the wireless unit and so if they are used on the same floor,

observe the following points when installing.

• Separate the antennas and ID tags by at least 3m.

• Set frequencies outside the range 12CH to 30CH.

10. Direction of waves emitted from the antennas

Antennas emit waves in certain directions, and there are certain directions

in which waves are received easily. These directions are known as the “di-

rectional characteristics.” The directional characteristics for pencil anten-

nas and magnet-base antennas when they are installed vertically are

donut-shaped, spreading outwards horizontally. Radio waves are emitted

in every horizontal direction but are not emitted upwards or downwards.

11. Other points about magnet-base antennas

• The magnet on the magnet-base antenna is very strong. Do not remove

the antenna by pulling on the cover or cable. Doing so may damage the

antenna. Be sure to hold the base when handling the antenna.

• Twist the cable as little as possible.

• Before mounting the antenna to the wireless unit, check that the plug

and jack are properly connected and then tighten them by twisting the

ring nut. When mounting, twist only the ring nut; do not twist the cable.

• Design the hole for passing the cable through so that the cable is pro-

tected.

Deciding the Antenna Installation Position Section 2-7

2-7-1 Example of installation inside a control panel

1. The wireless unit (1) is installed in the control panel using the two M4

screws provided.

2. The 16-point input terminal (2) is installed in the control panel using DIN

track or two M4 screws.

3. The antennas are attached to the control panel with magnets and the an-

tenna cables are fed into the control panel where they are connected to the

wireless unit (1) with connectors.

4. A shielded T-branch connector (4) is connected to the wireless unit (1), and

a shielded terminating resistor (5) and a cable with one connector (6) are

connected to it.

5. Wire the DeviceNet cable (of 6), the terminal block with a terminating re-

sistor (8), and the DC24V, 1A power supply (for the wireless unit (1) and

the 16-point input terminal (2)) to the multi-drop connection connector (7).

6. Wire the contact signals of the 16-point input terminal (2) to the PLC’s out-

put card (PNP). Use a separate power supply for I/O.

Status Monitoring Program Example Section 3-1

3-1 Status Monitoring Program Example

An example of a status monitoring program for the DeviceNet wireless unit is

given below.

In this example, the status of the DeviceNet wireless unit is checked at the

PLC CPU unit. If an error flag has occurred, an Explicit message command to

read the DeviceNet master status in the lower network where the wireless

slave station is connected will be issued.

In order to assign a status to the IN area, bit 3 of SW1 on the wireless master

station should be turned ON beforehand.

The IN area allocation for the wireless master station at the CS1 is shown

below.

3-1-1 Reading the DeviceNet master status of the lower network

The status assigned to the IN area of the master is monitored. Since the bit for

WNODE = 3 is 1, Instance ID is set to "03" and an Explicit message

(DeviceNet master status read) command is issued to the wireless slave sta-

tion.

"Maintain/Clear output when communication errors occur" is for setting

whether to maintain or clear the ON output when a wireless network error

occurs and while communication continues in the DeviceNet network that the

wireless slave station is connected to. (Although communication continues in

the wireless network when an error occurs in the DeviceNet network, the ON

input to the wireless master station at that time becomes "Maintain".)

Set the switches before turning on the power supply. Only the setting values

detected immediately after the power supply has been turned on are enabled.

Changes to switch settings after the power supply has been turned on are

ignored.

This test is for adjusting the installation position (confirmation of receiving

wave, etc.) and the setup conditions (selection of unused frequencies, selec-

tion of transmission output, etc.) at installation. Both master and slave stations

require the switch operation.

5-2-1 Preparation

• The DeviceNet master and DeviceNet slave do not need to be connected

for the installation test.

• Set the WNODE switch of the wireless master station to "00" and the

WNODE switch of a wireless slave station to "01" to "64", avoiding dupli-

cation.

• Since both the wireless master stations and wireless slave stations re-

quire the transmission power supply, connect them to the power supply

via the DeviceNet cable prepared for a micro-connector.

5-2-2 Test procedure

1. Set the mode select switch of the

wireless master station to "TEST",

and the WNODE switch to the WN-

ODE number of the wireless slave

5-3 Confirmation Test

This test is for checking the wireless communication status with each slave

station in the system in operation after installation. The test can be imple-

mented by the switching operation from the master station.

5-3-1 Preparation

• The DeviceNet master does not need to be connected for the confirma-

tion test. (The DeviceNet slave needs to be connected.)

• The confirmation test is employed for the inspection work after installa-

tion. Thus, the system registration is assumed to be completed before-

hand.

wireless master station to "TEST",

and the WNODE switch to the WN-

ODE number of the wireless slave

station to be tested. "01" is used for

this example.

Set SW3 to "bit 5 = ON".

2. Turn on the communication power

supply to the wireless master sta-

tion. The system is in test operation

status. The NS LED goes off and the

MS LED flashes green.

3. The LED display shows the receiv-

ing wave level "L1 to L9" if the wire-

less master station and the wireless

slave station to be tested have been

installed within the distance where

both stations can receive the electric

wave from each other.

If the WS LED lights green, the wire-

less communication link has been

established.

Relay Function Section 6-1

6-1 Relay Function

A wireless slave station can be used as a relay station when expansion of the

communication area is intended but the direct communication is blocked by

obstacles.

The relay station can select either (1) the mode that does not connect the

DeviceNet slave (dedicated relay station mode) or (2) the mode functions as

both the DeviceNet master and the relay station by connecting the DeviceNet

slave (non-dedicated mode) using DIP switches.

For details, refer to 4-2 DeviceNet Wireless Slave Station Specifications.

The maximum number of relay stages is 3 (no. of hops: 4).

A configurator is used for the relay station system setting. When the wireless

slave station is used in the dedicated relay station mode, the DeviceNet slave

is not connected. However, since the communication power supply is

required, the communication cable needs to be connected.

Also, in the relay station system, the WCH switches of all wireless units must

be set to an identical frequency.

The I/O connected with wireless slave stations are loaded first by ascending

order of DeviceNet node addresses in the wireless slave station, and then by

ascending order of wireless node addresses for the slave station (WNODE) in

the wireless master station.

Explicit Messages Addressed to the DeviceNet Wireless Master Station Section 7-1

Command format "Destination node address"

"Transmission destination node address"

Specifies the wireless master station node address (NNODE) controlled by

the Explicit message.

"ServiceCode", "ClassID", "InstanceID"

These are parameters to specify command types, processing objects, and the

details of the process.

"ServiceData"

This data is set as necessary. The maximum specifiable byte is 238.

Response format

1,2,3... 1. The issued Explicit message is normally responded to:

"No. of received bytes"

The number of bytes of the received data from the source node address and

after are responded to in hexadecimal.

"Communication source node address"

Specifies the wireless master station node address (NNODE) issued by the

command.

"ServiceCode"

If the system ends normally, the value resulting when the uppermost bit of the

ServiceCode specified by the command becomes ON is stored. Code 0004

Hex always results when an error is responded.

"ServiceData"

When a read command is issued, the read data is stored. 238 byte is the max-

imum.

Remote I/O Communications Performances Section 9-1

9-1 Remote I/O Communications Performances

This section describes the performances of remote I/O communications when

the DeviceNet wireless unit is used. Specifying communications timing as cal-

culated is difficult in a wireless network compared to a wire communication

network. Thus, the timings presented here are in accordance with the stan-

dard expressions and the actually measured data resulting from the OMRON

system test. This unit is not applicable for applications requiring real time con-

trol. Instead, use this data as a scale to determine if this unit is applicable to

your need.

The equations provided here are valid under the following conditions:

• The DeviceNet Master Unit is an OMRON product.

• The Master Unit is operating with the scan list valid mode.

• All of the required wireless slave stations and DeviceNet slaves have

been added in communications.

• No errors are being indicated at either the DeviceNet master unit or wire-

less units.

• Messages are not being produced in the Network (from another com-

pany's configurator, for example).

Note 1. The values provided by these calculations may not be accurate if another

company’s DeviceNet Master or Slave unit is being used.

2. This manual only refers to parts related to the wireless unit. For details

about the DeviceNet Master unit or the entire DeviceNet system, refer to

the "DeviceNet User’s Manual", and for details about Slaves, refer to the

"DeviceNet Slave Manual".

9-1-1 I/O response time

The I/O response time is the time it takes from the reception of an input signal

at an Input Slave (REMOTE I/O TERMINAL) to the output of the correspond-

ing output signal at an Output Slave (REMOTE I/O TERMINAL) via the pro-

cess by the ladder program in the PLC module.

Since the wireless master station operates as a DeviceNet slave virtually, and

the wireless slave station operates as the DeviceNet master, also virtually, a

time delay among wireless network is not noticeable in the operation from the

PLC. However, the actual I/O response time depends on the number of wire-

less slave stations, and if relayed, on the number of relay stages due to the

time delay among wireless networks and 1:N polling communication.

The following describes the maximum I/O response time.

Note For details on the Input I/O Unit input delay time and the Output I/O Unit out-

put delay time, refer to the information in the "DeviceNet Slave Manual"; for

details on the communication cycle and refresh processing time, refer to the

information of the remote I/O communication performance in the "DeviceNet

User’s Manual". Refer to the PLC Operation Manual for details on the PLC

cycle time.

The maximum I/O response time (T MAX) can be obtained from the following

expression:

TMAX = TIN +TOUT +4 × TRM +2 × TWCY +2 × TPLC +TRF

9-1-2 Wireless communication cycle time (TWCY)

Wireless communication delay time occurs in a wireless network when using

wireless units. The wireless communication delay time becomes longer

depending on the increase in the number of wireless slave stations and relay

stages. The unit is ms.

Wireless slave stations for which the Disconnect/Connect Switch is set to

ON (i.e., disconnected) are not included in the total cycle time of wireless

slave stations.

9-1-3 Actually measured reference data

Use the following values of the I/O response time (IN input -PLC processing -

OUT output) measured by the OMRON system test as reference.

The data described is the smallest and largest values resulting from 30 times

of continuous testing. The actual measurements could be longer than the

largest value depending on the environment where the measurements were

taken. Thus, use the results only as a reference.

Message Communication Performance Section 9-2

9-2 Message Communication Performance

9-2-1 Message communication time

When issuing a message on the DeviceNet network from one node to another

(data and CMND for SEND/RECV commands, FINS command for IOWR

commands), the time from the start of the departure of the message from the

DeviceNet master on the network until the end of the departure of the mes-

sage is called the "message communication time". This is defined as the time

required for the message to reach the DeviceNet slave.

If a DeviceNet wireless unit is used, since the wireless master station works

temporarily as the DeviceNet slave and the wireless slave unit works tempo-

rarily as the DeviceNet master, this will be the total of the following 3 times.

• "Message communication time" from the DeviceNet master to the wire-

less master station

• "Message communication delay time" from the wireless slave station to

the DeviceNet slave

• "Wireless communication extension time" within the wireless network

However, regarding the actual message transmission time, since some

latency may occur within the wireless network and 1:N polling is performed,

when there are several wireless slave stations or a relay, there are relay

stages. Actual data is provided on the following page as a reference. Although

this can not be used with applications that require real time control, you

should determine whether or not this data can be used as a reference.

Note Refer to the message communication capacity explanations in the DeviceNet

Slave Manual and the DeviceNet User’s Manual regarding message commu-

nication times on the DeviceNet network.

Troubleshooting Section 10-2

10-1-2 LED display

Under normal conditions, the dot LEDs of the wireless master station come on

depending on the registration status of the wireless slave station serial num-

bers, and the wireless slave station displays the node numbers (NNODE). In

the wireless slave station, the right and left dot LEDs come on in the scan list

invalid mode and go off in the scan list valid mode.

Under error conditions, "error code +error occurrence node" are displayed

sequentially, according to the error codes in the order of detection. The error

codes are conform to DeviceNet error codes. In addition, the receiving wave

level is displayed during the test.

10-2 Troubleshooting

This section explains the causes of errors, how to determine their locations,

and the actions to be taken when errors occur in a DeviceNet wireless unit.

10-2-1 How to locate errors when the system is having trouble

Trouble assumable in the system using the DeviceNet wireless can be roughly

classified into the following two cases.

1,2,3... 1. Hardware error in each unit

2. Communication error in each network (the upper DeviceNet network be-

tween the DeviceNet master unit and wireless master station, the wireless

network between the wireless master station and a wireless slave station,

the lower DeviceNet network between a wireless slave station and the De-

viceNet slave connected with a wireless slave station)

Hardware errors in each unit can be determined either by the LEDs of the unit

or by the fact that a unit is not added to the upper unit (this could be a wireless

slave station, the wireless master station if it is a wireless slave station, or a

DeviceNet master if it is the wireless master station) to which the unit should

have been added.

(Ex. 1) A hardware error occurs in a DeviceNet slave:

(Ex. 2) A hardware error is present in a wireless slave station:

Hardware errors in each unit can be determined either by the LEDs or the sta-

tus of the master station of each network (this could be a wireless slave sta-

work). When an error unit is found in each network, the cause can be pin

down by implementing the communication test on each network after the set-

tings of the unit in concern have been checked.

(Ex. 3) A hardware error is present in the lower DeviceNet network:

(Ex. 4) A communication error is present in the wireless network:

When a wireless slave station is added during startup, the

error can be determined by the LEDs (WS LED, LED display)

of the wireless master station, which is the master station of

the network. Since wireless communication errors cannot be

determined by the LEDs due to the interference wave in the

middle of communication, this is made possible by using the

test function of the wireless unit, etc.

Clean the network regularly as described below in order to keep it in its opti-

mal operating condition.

• Wipe the Unit with a dry, soft cloth for regular cleaning.

• When a spot cannot be removed with a dry cloth, dampen the cloth with a

neutral cleaner (diluted to 2%), wring out the cloth, and wipe the Unit.

• A smudge may remain on the Unit from gum, vinyl, or tape that was left on

for a long time. Remove the smudge when cleaning.

!Caution Never use volatile solvents such as paint thinner or benzene or chemical

wipes. These substances could damage the surface of the Unit.

dard or adjust this unit.

The following table shows the operating ambient temperature and humidity ranges for each unit

10-3-3 Replacing nodes

Each node (master, slave, wireless master station, wireless slave station)

makes up the network. The entire network is affected when a node is faulty, so

a faulty node must be repaired or replaced quickly. We recommend having

spare parts available to restore network operation as quickly as possible.

Precautions Observe the following precautions when replacing a faulty unit.

• After replacement make sure there are no errors with the new unit.

• When a unit is being returned for repair, attach a sheet of paper detailing

the problem and return the unit to your OMRON dealer listed at the end of

this manual.

• If there is a faulty contact, try wiping the contact with a clean, lint-free

cloth dampened with alcohol.

!Caution To prevent electric shock when replacing a unit, be sure to turn OFF the

power supplies to all of the nodes (master and slaves) before removing the

faulty unit.

Current Consumption List

*1 The wireless unit receives the total power supply from the communication power supply via the dedicated

DeviceNet cable. Thus, the total power supply listed here does not distinguish the internal circuit area from the

communication area. Taking the maximum current at startup into consideration, however, use a power supply

of at least 350mA. If using an OMRON S82K or S82J switching power supply, use a model with a capacity of at

least 30W (S82K) or 25W (S82J).
