Product Description
4.2.2 Read/Write Heads MVH500-F15/MVH2000-F15/MVH5000-F50
The read/write head, which is controlled by the MVI-D2-2HRX, sends and receives
data from data carriers, as long as the data carriers are located inside the
transmission area. The read/write head transmits the received data to the
MVI-D2-2HRX.
•
For communication with the data carrier three models of read/write heads are
available: MVH500-F15 for medium distance, MVH2000-F15 for long distance,
MVH5000-F50 for extra long distance.
•
2.45 GHz microwaves are used for data transmission between read/write heads
and data carriers. Since the read/write heads operate with circularly polarised
microwaves, transmission interference due to metal reflection is minimised.

Usage
The data carrier has a built-in lithium battery for data backup. The battery has a limited
life span (MVC-60-64K and MVC-60-256K). Replace the data carrier with a new one
before the batteries are exhausted. The battery of the MVC-60B-64K must be
replaced in good time. Delay in replacement may cause malfunction of the data
carrier. Battery life can be checked by referring to the production year, -month,
storage time, operation time, and battery use ration by means of the program.
Cleaning
To clean the control interface unit, use a dry, soft cloth. Do not use any volatile solvent
such as alcohol, thinner, freon, or even a wet cloth for cleaning, as this may cause a
deformation or color change.
Storage
Since the control interface unit and the data carrier have lithium batteries inside, do
not put them into fire. The lithium battery may explode or burn which is quite
dangerous.
Date of issue

When the front angle of the data carrier and the front angle of the read/write head is
between 0° and 45°, the data carrier's transmission area is reduced accordingly.
When the data carrier is installed with a slant, reduce the distance between the read/
write head and data carrier as much as possible.
Communication in area A is possible. However, this area may suffer interference from
surroundings. Even in area B and near the area, existence of an object may change
the transmission area or make a data transmission between the read/write head and
the data carrier impossible within the recommended distance. For installation, first
carefully check the transmission availability in a field test.

5.4.2 Influence of Obstacles
When transmitting data between the read/write head and the data carrier, remove any
reflective object (metal etc.) or dielectric object (human body or moist wooden
material) from the data transmission area. When such an object is within the
transmission area, (see figure 5.2) the transmission of microwaves may be interfered
and therefore a normal transmission would not be possible.
Microwaves are reflected when they impinge upon a reflective object and they may
be absorbed when they impinge upon a dielectric object.
A cover used to protect the read/write head or the data carrier should be made of
plastic with low dielectric properties (polyethylene fluoride etc.). In addition, it must be
ensured that the cover does not affect transmission in the current transmission
system arrangement.
When reflective objects (such as metallic objects) are located near the read/write
head or the data carrier, transmission errors may even occur within area “A” see
figure 5.2. Please check the constant data transmission between the read/write head
and the data carrier by simulating and testing the conditions of the current system
arrangement.

The unique or odd times reflected wave does not influence the data transmission,

•
The even times reflected wave weakens, since the distance between the read/
write head and the data carrier is longer than the direct wave from the read/write
head, so that the data carrier can eliminate the reflected wave within its receive
circuit. A transfer error occurs, when the data carrier cannot eliminate the
reflected wave in its receive circuit, since the intensity of the reflected wave
equals the intensity of the direct wave.

5.4.3 Influence of Liquids
(Rain, snow, coolants, cleaning liquids, human bodies)
Make sure that no water film forms between the data carrier and the read/write head,
while transmitting data to the data carrier.
Thermal Influence of Microwaves
•
When microwaves are projected on water, water molecules are separated and
oscillated. Friction heat caused by colliding molecules increases the water
temperature.
•
When there is a water film between the data carrier and the read/write head, radio
wave energy is converted into thermal energy and the radio wave attenuates.
Therefore, the available transmission distance is reduced.
Note: Oil is not activated by microwaves and therefore does not reduce the
available transmission distance.
•
70 % of the human body consists of water so that transmission is not possible,
when there is human body between the data carrier and the read/write head.
Reduction of the Actual Transmission Distance
•
The available transmission distance is neither reduced by individual water-drops
on the data carrier or the read/write head surface nor by moistening the surfaces
with water.
•
When the data carrier is dipped into water, or when there is a waterfall between
the data carrier and the read/write head, the maximum transmission distance
reduces according to the waterfall's thickness.

Influence of Rain and Snow
The transmission distance is not influenced by rain or snowfall occuring between
the data carrier and the read/write head.
•
When the data carrier or the read/write head are operated during heavy snowfall
or rain, a water film may form on them causing the transmission distance to
diminish.
•
When the data carrier or the read/write head is covered with dry snow or snow
crystals, the molecules are not separated by microwaves and the radio waves can
pass through the snow. However, wet snow may attenuate radio waves and
reduce the transmission distance.

IDENT-M System V
Installation
Influence of Coolants
When using a water-soluble coolant for working processes, it must be ensured that
no coolant film forms between the data carrier and the read/write head during the
transmission process.
1. Install a valve, in order to stop the coolant supply during the transmission process.
2. Be careful to install the data carrier and the read/write head at a place where a
coolant film cannot form during transmission.
3. Use a device (a shade or a pail), to prevent the flow of coolant so that no coolant
film forms between the data carrier and the read/write head.
Influence of Cleaning Liquids
•
When pallets or workpieces are cleaned, while installing the data carrier, it must
be ensured that no water film forms on the surfaces of the data carriers (vapours
caused by cleaning liquids do not affect the transmission).
•
When installing a plastic protective cover on the front side of the data carrier, it
must be ensured that no cleaning liquid remains inside the cover plate.
5.4.4 Influence of Metallic Objects
(Conveyor belts, pallets, machines and workpieces)
Since radio waves reflected by metal objects close to the data carrier and the read/
write head come from different directions, the angle and the height of the read/write
head have to be adjusted so that transfer errors due to multiple transmission are
prevented.
Microwave Reflection of Metal Objects
Microwaves are characteristically reflected by metallic objects. When a metallic
object is located close to the data carrier or the read/write head, the data carrier
receives direct radio waves from the read/write head as well as radio waves
reflected from metallic objects. When direct radio waves and reflected radio
waves arrive in reverse phase difference, these two radio waves cancel each
other out and the radio signal weakens. The same applies to radio waves from
the data carrier to the read/write head.
•
When using a data carrier in a production line, metallic objects with complex
shapes may be near the data carrier and the read/write head. Therefore, they
receive reflected waves from different directions. In order to prevent this,
measures must be taken to screen the reflected waves.

IDENT-M System V
Installation
Presence of a Metallic Object with Complex Reflective Surface
The IDENT-M microwave identification system uses a circularly polarised wave
system and is also screened, to prevent the influence of metal reflection. Some
shapes of metal objects or their arrangement next to the data carrier and the read/
write head may cause the transmission not to function trouble-free. When direct or
double reflected waves reach the receiver with the same intensity, the radio signal
may be attenuated or changed.
Measures against Reflected Waves
Altering the read/write head installation angle changes the direction of the reflected
wave which superimposes the direct wave. In this way, it is possible to eliminate
transmission errors.
1. Planning the arrangement
Provide an angle adjustment function for the read/write head, thereby enabling it
to be adjusted to ±30° in up/down and left/right direction against the crossing point
of the read/write head central axis as well as the data carrier distance.
2. Adjusting the arrangement
Adjust the read/write head angle in order to minimise the transmission distance
between the data carrier and the read/write head.

Influence of Casting Dust (Cutting powder, slag)
When casting dust settles on the data carrier or on the read/write head, the radio
waves may attenuate thereby reducing the available transmission distance. When
using the data carriers and the read/write heads in a metal processing plant,
precautions must be taken to prevent cutting dust from settling on the devices.
Attenuation of Radio Waves due to Metal Dust, Oscillation of Metal Dust
•
The microwave system uses 2.45 GHz radio waves. The 2.45 GHz radio wave
has a wave length of 122 mm and resonates with metallic objects, that have
approximately 1/2, 1/4 or 1/8 of this wave length. This may attenuate the radio
wave energy.
•
When a metallic object with 10 mm length of side adheres to the data carrier or
the read/write head, the occuring resonance may cause the radio signal to
attenuate and the transmission distance to be reduced.
Reflection by Metal Dust
Date of issue
03.05.2001
Large amounts of metal dust or sliced particles may reflect microwaves, attenuate the
radio signal and reduce the transmission distance.

IDENT-M System V
Installation
Settling of Cutting Dust during Cutting Procedures
1. When the data carrier or the read/write head is mounted vertically and its surface
is moist from coolant, fine metal dust may settle on the surface which can cause
the radio wave to attenuate a bit, however, without reducing the transmission
distance.
2. When cutting dust settles on the upper side of the data carrier or the read/write
head, it may drop on their front sides and considerably reduce the transmission
distance (see figure 5.3).
3. When mounting the data carrier or the read/write head in an upright position it
must be ensured that cutting dust does not accumulate on its surface.
Methods to Prevent Metal Dust Accumulation
The following measures have proved to be advantageous for the application:
1. When transmission is stopped, use a steam jet or compressed air to remove the
cutting dust from the data carrier or the read/write head.
2. Provide plastic protective covers in order to protect the data carrier and the read/
write head from accumulating cutting dust (see figure 5.4).

steepest possible slope
angle thereby preventing
dust accumulation on top of
the housing.

Protection against Shorted Output
When the output is shorted, the output circuit of the control interface unit may be
destroyed. That is why a fuse should be integrated in order to protect the output.
Precautions against Surge Currents at Lamp Load
An incandescent lamp can generate a surge 10 to 20 times greater than the nominal
current. Two precautions can be taken in order to decrease the surge: Inserting a
bleeder resistor or inserting a current limiting resistor.

Protective Measures against Surges in Inductive Loads
When the circuit is opened by a coil, some thousand volts of voltage surge may occur,
depending on the coil. When a coil generates a high voltage, appropriate protective
measures should be taken against the surge. Protective measures against voltage
surge may extend the lifetime of the relay.

•
Commands that access the data carriers are available for each system.
•
The occasional execution system is automatically used, when commands only
address the control interface unit without accessing a data carrier.
•
The type of the communication startup system is set by writing one byte to the
A008h address of the control interface unit's system memory:

IDENT-M System V
Communication Systems
Application
Occasional execution system:
•
The MVI-D2-2HRX immediately executes a command.
•
Used, when the host controller detects the presence of a data carrier:
1. Started, by connecting the proximity switch to the host controller.
2. Data carrier identification time: endless. Starts, when a data carrier is detected.
3. An operator judges the existence of a data carrier and starts the command, for
instance, by striking a key.
Command stay system:
•
When the MVI-D2-2HRX detects the existence of a data carrier by means of a
proximity switch which is connected to a trigger input, the MVI-D2-2HRX executes
the current command and returns the result to the host controller.
•
After completion of the command stay system operation, the MVI-D2-2HRX is
ready for operation in the occasional execution system (available for
simultaneous multiple operations).
•
Used, when existence of a data carrier can be detected e.g. by a proximity switch
and when the command has already been registered prior to the detection.
•
Differences from the command register system:
1. Commands can be easily changed by the host controller's program.
2. Commands are purged after each operation.
3. The host controller has to send a new command after each operation.
4. Different modes of operation are available for each trigger input.
5. The command stay system performs in a sensible manner, when the result
influences the next command.
Command Register System:
For each detection of a data carrier by means of the proximity switch which is
connected to the trigger input. The MVI-D2-2HRX executes the command stored
in the MVI-D2-2HRX and sends the result to the host controller.
•
The command is stored to the MVI-D2-2HRX system memory.
•
The command which is to be executed on activation of the trigger input, has been
stored to the system memory in advance.
•
Other stored commands are available until the trigger input is switched off
(available for simultaneous multiple operations).
•
Used, when existence of a data carrier can be detected, for instance by means of
a proximity switch and when all transmission processes with the data carrier have
already been registered.

IDENT-M System V
Communication Systems
•
Simple installation, because on-site connection of the proximity switch to the MVID2-2HRX is possible.
•
Differences from the command stay system:
1. The command does not disappear when the MVI-D2-2HRX is battery-buffered.
This means that it is not necessary to send a command to the control interface
unit at the end of each operation.
2. Commands are changed by altering the register content of the MVI-D2-2HRX.
3. During an individual operation, the host contoller can concentrate on receiving a
response from the MVI-D2-2HRX, enabling the host controller to perform less
tasks.
Read/Write Head Scan System:
The read/write scan system supports commands which address individual read/write
heads, as well as scan commands for all connected control interface units and read/
write heads.
7.1.2 Response Return System
Two systems, the auto response system and the response request system are
available for response from the MVI-D2-2HRX to the host controller.
•
The system type is set by writing one byte to the A00Ah address of the control
interface unit's system memory:
Value
Command
Auto response system (basic setting)
Response request system

•
After ending the transmission procedure, the MVI-D2-2HRX automatically returns
the transmission result (end message) to the host controller.
•
The end message timing cannot be determined by the host controller.
Application:
•
Mainly used for configuration of a host controller and a MVI-D2-2HRX connection.
•
Used for transmission configuration of the host controller and multiple MVI-D22HRX.
Date of issue
03.05.2001
In order to prevent collision of responses on transmission lines, it is better not to
start the next command of another station, until the command of the currently
transmitting station is completed.

IDENT-M System V
Communication Systems
Response request system
•
After completion of the command, the MVI-D2-2HRX returns the transmission
result (end message) to the host controller, in accordance with the request from
the host contoller (hereafter referred to as “acknowledgement request”).
•
The host controller prescribes the timing for sending the end message.
Application:
7.2
•
Mainly used for the configuration of a host controller and multiple MVI-D2-2HRX.
•
Since the system returns the end message on request of the host controller, its
processing time is longer than the auto response system's processing time.
Occasional Execution System
Unlike the command stay system and the command register system, the occasional
execution system can start accessing the data carrier via the host controller,
regardless of the MVI-D2-2HRX trigger input condition.
7.2.1 Occasional Execution System + Auto Response System
Transmission Procedure
1. The host controller sends commands to the MVI-D2-2HRX.
2. After receiving the commands, the MVI-D2-2HRX returns an acknowledgement
to the host controller.
3. After the command has been executed, the MVI-D2-2HRX returns the end
message to the host controller.

7.2.2 Occasional Execution System + Response Request System
Transmission Procedure
1. The host controller sends commands to a specified MVI-D2-2HRX station.
2. The specified MVI-D2-2HRX station sends an acknowledgement to the host
controller, as soon as it receives the command.
3. After receiving the acknowledgement, the host controller sends an
acknowledgement request to the MVI-D2-2HRX.
4. When the specified MVI-D2-2HRX station receives the acknowledgement
request after executing the command, it sends the end message to the host
controller.
5. The host controller sends the acknowledgement request until the result returns
from the specified MVI-D2-2HRX station. When the host controller sends an
acknowledgement request during operation of the MVI-D2-2HRX, the latter
returns an acknowledgement („#71“).

Transmission Procedure:
1. The host controller sends a command to the MVI-D2-2HRX.
2. After receiving the command, the MVI-D2-2HRX sends the acknowledgement to
the host controller and stores the command.
3. The MVI-D2-2HRX trigger input is activated.
4. As long as the trigger input of the read/write head is ON, the MVI-D2-2HRX
executes the command and sends the end message to the host controller.
It is possible to execute further commands in the occasional execution system
(1à2à4) while the trigger input is active (ON).
Note: In case of commands without data carrier access, the system changes to the
occasional execution system mode, regardless of the selected communication startup

•
Up to 8 transmission procedures can be stored for each read/write head. A
storage location number from 1 to 8 is allocated to each command for
transmission procedures.
•
Each activation of a trigger input executes the stored function of the
corresponding number, which has been allocated by means of the 75h command.

7.4.1 Command Register System + Auto Response System
Transmission Procedure
1. The host controller sends command 75h to the MVI-D2-2HRX.
2. After receiving command 75h, MVI-D2-2HRX sends an acknowledgement to the
host controller. The stored process with the corresponding number allocated by
command 75h, is executed while the trigger input is active. (System memory of
MVI-D2-2HRX: address 9010h).
3. The MVI-D2-2HRX trigger input switches ON.
4. The MVI-D2-2HRX executes the transmission function of the corresponding
storage number, allocated by command 75h and sends the end message to the
host controller.
5. With each activation of the trigger input, the transmission procedure, allocated by
command 75h, is executed (3)à(4). The host controller can only wait for reception
of the end message.
6. The next stored transmission function can be called by means of command 76h
while the trigger input is set.
• Send command 76h. (2)à(4)
•
If the end message is incorrect during transmission between the host controller
and the MVI-D2-2HRX, the host controller can send the command to the MVI-D22HRX for renewed execution (command 77h ). However, this function is available
only while the trigger input is active.
•
In order to stop transmission while the trigger input is active, the host controller
sends a halt command (used when a MVI-D2-2HRX trigger input is active:
address 9010h = 0). Although the trigger input is active, the transmission function
is not executed.
•
In order to change the transmission function, after setting the trigger input from
OFF to ON, command 75h must be sent.
Additional Description
Command 75h
This command activates a stored transmission instruction, which is executed with
a rising edge at the trigger input. This is required, in order to send a transmission
procedure in case of a rising edge of a trigger input or a change of the
transmission function.
•
Command 76h
After the transmission procedure, instructed by command 75h, has been
executed, this command enables the data transmission of the next command to
be activated, when the trigger input is in ON state. The command must be sent to
the MVI-D2-2HRX for each transmission which is executed.

address 9010h).
3. When the trigger input of the MVI-D2-2HRX is active, the registered transmission
function, allocated by command 75h, is executed.
4. The host controller sends an acknowledgement request to the MVI-D2-2HRX, in
order to inquire the result of the operation.
5. After reception of the acknowledgement request, the MVI-D2-2HRX sends an end
message to the host controller, when the transmission procedure is finished.
6. The transmission function, allocated by command 75h, is executed (3)à(4)à(5)
whenever the trigger input is ON.
7. The transmission function, allocated by command 76h, is available (2)à(4)à(5)
while the trigger input is ON.
• Command 75h is sent, in order to change the transmission function, when the
trigger input is set from OFF to ON.
When the end message is incorrect during transmission between the host
controller and the MVI-D2-2HRX, the host controller sends the command to the
MVI-D2-2HRX for renewed execution.
•
In order to stop transmission, while the trigger input is active, the host controller
sends a halt command. (Used when a trigger input of a MVI-D2-2HRX is active:
address 9010h = 0).
•
The storage process is not executed, even if the trigger input is ON.

Read/Write Head Scan System
The read/write head scan system supports commands for individual read/write heads
just as it successively performs the same operation for multiple read/write heads and
MVI-D2-2HRX control interface units.
•
The system successively sends one token to the connected MVI-D2-2HRX
control interface unit. When a MVI-D2-2HRX has executed the desired command,
it sends an end message.
•
When a MVI-D2-2HRX does not receive a response from a data carrier within a
specific time, regarding the microwave transmission, a message is sent to the
next MVI-D2-2HRX.
•
The host controller waits for an end message, when it sends a command “read/
write head scan” to a MVI-D2-2HRX.
•
The host controller controls the transfer time of the entire system.
•
The read/write head scan system is the only system available as communication
startup system. (When attempting to perform the communication startup system
with other systems, an error is reported within the MVI-D2-2HRX).
•
Response system: The auto response system as well as the response request
system are available.
Connection conditions:
•
Be sure to connect the host controller to a MVI-D2-2HRX with station number “0”.
•
Write the highest station number of the connected MVI-D2-2HRXs to the system
memory of the MVI-D2-2HRX number “0” (address A00Bh, one byte). Note: When
the value for the last station is set to “0”, then the system works with only one MVID2-2HRX.
Setting the last station to “0”:
Use this value in case of a connection between the host controller and a MVI-D22HRX.
•
Set the station number (SW3) of the MVI-D2-2HRX to “0”.
•
Operation: The number “0” control interface unit, keeps repeating the
transmission procedure until one of the two read/write heads communicates with
the data carrier.
•
When using only one control interface unit, the RS 232C as well as the RS 422
interface standards are available via the corresponding terminal block and
connector. In case of multiple control interface units, the RS 422 interface should
be used.

7.5.1 Read/Write Head System + Auto Response System
(between the host controller and the MVI-D2-2HRX with station number “0”)
Transmission Procedure
1. The host controller sends a “read/write head scan” command to the MVI-D22HRX with station number “0”.
2. After receiving the command “read/write head scan”, the MVI-D2-2HRX number
“0” sends an acknowledgement to the host controller.
3. After having received the acknowledgement, the host controller waits for the end
message.
4. The MVI-D2-2HRX executes the function “read/write head scan” for all read/write
heads from station number “0” to the last station number.
5. When the MVI-D2-2HRX has completed the transmission procedure with the data
carriers, station number “0” sends the end message including the MVI-D2-2HRX
station number and the number of the read/write head, which had executed the
function, to the host controller.
Each MVI-D2-2HRX executes transmission functions from read/write head
number “0” to read/write head number “1”.
•
The token is sent to the next MVI-D2-2HRX, provided that there was no data
carrier error, no read/write head error and no MVI-D2-2HRX error.
•
In addition to the read/write head scan mode, the host controller can send other
communication commands to any control interface unit.

Note:
•
Station number “0” is required for transmission to the host controller (e.g.
personal computer) as well as to the MVI-D2-2HRX.
•
The read/write head scan procedure starts with the station number following the
previous operation as well as the read/write head number of the previous
operation.
Ex. 1: When the scanning ends with station number “1”, and read/write head number
“1” executes the last operation, the operation is restarted with station number “2” and
read/write head number “0”.
Ex. 2: When the scanning ends with station number “1”, and read/write head number
“0” executes the last operation, the operation is restarted with station number “1” and

7.5.2 Read/Write Head System + Response Request System
Transmission Procedure
1. The host controller sends a “read/write head scan” command to the MVI-D22HRX number “0”.
2. After receiving the command “read/write head scan”, station number “0” sends an
acknowledgement to the host controller.
3. The MVI-D2-2HRX excutes the function “read/write head scan” for all read/write
heads from station number “0” to the last station number.
4. After receiving the acknowledgement, the host controller sends a result request
to station number “0”.
5. After receiving the function request from the host controller, the MVI-D2-2HRx
sends the end message including the MVI-D2-2HRX station number and the
number of the read/write head, which has executed the function, to station
number “0”.
The host controller keeps sending acknowledgement requests until the result
returns from station number “0”.
•
Each MVI-D2-2HRX executes transmission functions from read/write head
number “0” to read/write head number “1”.
•
The token is sent to MVI-D2-2HRX, provided that there was no data carrier error,
no read/write head error and no MVI-D2-2HRX error.
•
Further transmission procedures with the MVI-D2-2HRX (station number “n”),
which executes the transmission function via read/write head scan, are available
to the host controller.

Operation
1. When MVI-D2-2HRX on station number “0” cannot receive a message from the
data carrier after a certain number of repetitions, MVI-D2-2HRX number “0”
transmits a token to the next and the following stations.
2. When the last MVI-D2-2HRX station cannot receive a message from the data
carrier, the last station transmits a token to station number “0”.
3. When an MVI-D2-2HRX successfully transmits data to a data carrier, MVI-D22HRX station number “0” returns an end message to the host controller.
Note:
As soon as the operation is completed, the next scanning starts with the next station

Simultaneous Processing of Commands
7.6.1 With One Read/Write Head
When the MVI-D2-2HRX receives the second command before sending the end
message for the first command, two commands are processed in one read/write head
and an error message (error at command execution) is sent in response to the second
command.
Note: Based on the error code, the host controller identifies to which commands the
error messages belong. The host controller is able to distinguish unambiguously
between the error code, generated by executing the first command, and the error
code of the second command. (Error at executing a command).
The MVI-D2-2HRX does not cancel the first command and executes the transmission
procedure. Then the following acknowledgement is sent:
1. Auto response system: Return end message during a process such as a data
carrier access.
2. Response request system: After a process, such as a data carrier access has
been accomplished, the end message is returned after receiving the result
request.

7.6.3 Description
•
When the microwave communication of read/write head 0 and read/write head 1
is doubled, the MVI-D2-2HRX performs simultaneous processing for both read/
write heads.
•
Each response return system has a different end message.
1. Auto response system: Acknowledgement from the first channel, that has
completed the microwave transmission.
2. Response request system: The first channel to receive an acknowledgement
request returns an acknowledgement after executing the microwave
transmission.
Since the commands, acknowledgements, result requests and end messages
have a read/write head number, the host controller is able to identify the read/
write head number.
•
Make sure that the command for the second read/write head is not transmitted
until the acknowledgement for the first read/write head has been received and
vice versa. When the acknowledgement of one channel collides with the
command of another channel, the MVI-D2-2HRX can neither receive the
command (command (1) of read/write head 1) nor execute the function.

Transmission Procedure
Transmission Procedure
8.1
Overview
Two types of transmission functions can be distinguished: “Communication with data
carrier”, such as transmission between the host and the data carriers, as well as
between MVI-D2-2HRX control interface units and data carriers; and “MVI-D2-2HRX
access function”, which represents transmission between the host controller and the
MVI-D2-2HRX.
The MVI-D2-2HRX has a data carrier buffer for each read/write head which is in the
same memory area as the data carriers are. (The MVI-D2-2HRX has the same
address structure as the data carrier.)
The command register system allows only commands that access data carriers to be
stored as transmission procedure. Commands which only access the control interface
unit, cannot be stored in the command register system.

IDENT-M System V
Transmission Procedure
8.1.1 Verification
When the two verified data differ, the MVI-D2-2HRX treats this as a verification error.
The address of the differing data is included in the error message. If an error, e.g. a
data transmission error occurs during “read and check”, the end address of the write
data is likewise attached to the error message.
8.1.2 Copy
The copy command reads data of a specified range of the data carrier which is facing
the read/write head and writes them into the data carrier, which is facing the other
read/write head. In order to accelerate data processing time, this function is executed
in the MVI-D2-2HRX without data storage in the connected host controller.
1. Usable memory area of the data carrier
•
Data area MVC-60-64K: 7552 bytes
•
Data area MVC-60-256K: 31 kbyte
2. When instructing to copy data, enter the read/write head number from which the
data should be read.
3. When ID code allocations are used, the ID code of the data carrier which has to
be recorded, must be specified.
4. Applications
• When a workpiece reaches the end of the production line and is then placed on
another pallet for the next process, the data should be copied from one data
carrier to the data carrier of the next process, in order to keep current processing
and information running.
•
All data stored in the data carrier must be copied before the batteries are
exhausted.
8.1.3 Block Check
This function checks whether the data of the data carrier have only changed due to
write, clear and copy commands. This command divides the data area and the system
area of the data carrier (see the following table) and checks all blocks from the start
block to the following blocks for errors.
Date of issue
03.05.2001
Example: This function checks block 1 and block 2, when 007Fh is set as starting
address and the byte number is two byte. When any error is found in these blocks,
the MVI-D2-2HRX treats this as a block check error.

8.1.4 Self-Diagnosis of the Data Carrier
In normal operation the data carrier performs a self-diagnosis. The diagnosis is
carried out in the following order: ROM check, RAM check and data carrier battery life
check. These three checks are also available individually.
8.1.5 ROM Check
This check determines whether the ROM which controls the data carrier works
trouble-free. When it has an error, the MVI-D2-2HRX treats this as a ROM error.
8.1.6 RAM Check
This function checks the RAM integrated in the data carrier within the assigned range.
When an error is found, the MVI-D2-2HRX treats this as a RAM error. The start
address and the error number are attached to the error message.
8.1.7 Checking the Battery Life of a Data Carrier
When an error occurs during the check, an error code indicating low battery voltage
or a long service life is displayed. The battery or the data carrier have to be replaced.
In order to rescue the contents of a data carrier, you have to save the memory
contents of the data carrier by a normal copy command. The warning information (W
+ error position) for low battery voltage is inserted into the end message at the start
of the checksum code even when the test is completed without any errors (see
page 185).
When an error occurs, the error code of the MVI-D2-2HRX error (ROM error/RAM
error/warning low battery voltage) is indicated. For details on the warning function for
low battery voltage see chapter 8.1.7 “Checking the Battery Life of a Data Carrier”.

IDENT-M System V
Transmission Procedure
3. Storage of commands
This storage and execution is only available when the command register system
is used as communication startup system (set memory address A008h to 2).
• Storage
Determine the contents of the transmission function (transmission code,
attributes etc.) and store it as command.
Determine the memory area by inserting storage numbers 1 to 8 into the field
“registration” of the command.
Execution method
When the MVI-D2-2HRX receives the command (command code 75h) from the
host controller, the storage number, which is to be executed when the trigger input
is activated, is stored in the MVI-D2-2HRX system memory (address 9010h).
Each time the trigger input is activated, the MVI-D2-2HRX executes the
registered command, which is allocated by the host controller by means of the the
75h command.
While the MVI-D2-2HRX trigger input is active, the communication function,
allocated by command 75h, is executed.
•
Halt
The instruction execution can be stopped by sending the command “halt”
(command code 74h). In this case, the MVI-D2-2HRX does not start the
transmission even if the trigger input is active (ON) (address 9010h = 0).
•
Other
The MVI-D2-2HRX indicates an error when you try to start the function by means
of the start command with other than the command register system.
Store the write data to the data carrier buffer of the MVI-D2-2HRX.

Transmission Procedure
4. Time protocol of the transmission
The MVI-D2-2HRX stores the processing time from the start to the end of the
transmission between the read/write head and the data carrier onto its memory
addresses 90A0h to 90B3h. These processing times are subdivided into current value,
mean value, maximum and minimum value. The “clear protocol” function from the
host controller can initialise the maximum, minimum and mean value. It is not possible
to write with any other function.

transmission between the read/write head and the data carrier onto its memory
addresses 90C0h to 90CBh. The “clear protocol” function from the host controller
can initialise the maximum, minimum and mean value. It is not possible to write

7. Error protocol
When the result of a command is faulty the MVI-D2-2HRX stores the error
protocol to its memory addresses 9100h to 9D81h.
• The MVI-D2-2HRX stores the error contents onto the address which is set 32
bytes before the start address of the protocol in the “storage protocol pointer”
(address: 9100h, 9101h).
After the storage of the error contents, the start address of the protocol is set 32
bytes ahead of the “storage protocol pointer”.
•
The initial value of the “storage protocol pointer” is 9102h.
•
The error protocol area can be reset by means of the host controller's “clear
protocol” function.
•
When the protocol data reach 100, the data is overwritten by protocol data 1.

The number of the read/write head is determined by the terminal number of the
read/write head at the MVI-D2-2HRX.
•
When the read/write head scan is used, the character “ *” is inserted
in the command.
•
In order to copy data (with check) between the read/write heads, the read/write
head number of the data source has to be set.
•
When the special area of the MVI-D2-2HRX system memory is accessed, the
host controller accesses the same address, disregarding whether the command
is set to 0 or 1.

Commands
9.2.3 Check Sum
In order to improve the reliability of the data transmission, the MVI-D2-2HRX can
ascertain errors both with checksum tests and parity checks (Checksum range see
page 121).
Checksum range
Command
? contents

C C
(H) (L)
Test procedure
1. All data of the station number is added up to the end of the command contents or
to the end of the messages, and the lowest byte of this amount is converted to
ASCII.
2. The data is correct when the sum across the checksum range and the checksum
itself is 0. When the overall result is a number not equal to 0, this is treated as an
error.
Data creation during the checksum procedure
1. Adds up the ASCII values of the station numbers up to the command contents or
to the end of the message contents (just before the checksum code).
2. Constitutes the two's complement from this sum.
• Two's complement: All data bits are inverted (0 to 1, 1 to 0) and 1 is added.
Ex.: Two's complement of 4Eh is B2h.
4Eh à
01001110
¯
invert
10110001
¯
add 1
10110010
à B2h
Date of issue
03.05.2001
3. Divide the data to the first 4 bits and the second 4 bits and convert them to ASCII
code.
When the calculation of the checksum is too expensive, the checksum can be
replaced by “@@”.

Attributes of the Communication Start System (Between Read/Write Head and
Data Carrier)
The attribute determines whether the data carrier detection time shall be limited
(single read) or unlimited (auto read). Moreover, it determines whether all data
carriers, data carriers with specific or data carriers with other ID codes shall be
activated. The attribute also determines whether the end message is to be sent with
or without the ID code.
Date of issue
03.05.2001
Data carrier detection method:
At the start of communication with a data carrier, the data carrier should be within the
transmission range of a read/write head. In order to detect a data carrier within the
transmission area both an external switch (auto read) and a read/write head (single
read) can be used. For setting see page 138.

Setting the Attributes
Selection values of the communication start system and the ID code returns between
a read/write head and data carriers are referred to as attribute codes.
•
The attribute code consists of detection method, ID code allocation and allocation
of ID code return/non-return.
•
The attribute code is represented by one ASCII character.
•
When ID codes allocate function or non-function, they should be set in the
command (ID code setting position is described at each message of the
transmission function).
•
If no ID code is allocated, an ID code setting for the command is not required.

IDENT-M System V
Commands
When transferring data of more than 512 bytes, please proceed in the following way:
From Data Carrier to Host Controller
•
Repeated reading of data with up to 512 bytes by means of the read instruction
(10h).
•
Combine the MVI-D2-2HRX read instruction (15h) with reading from the data
carrier to the MVI-D2-2HRX (command 13h) or with reading and checking from
the data carrier to the MVI-D2-2HRX (command 14h).
Read data from the data carrier to the MVI-D2-2HRX data carrier buffer together with
the data carrier's read data (with check) to the MVI-D2-2HRX (max. 7552 or 30976
bytes).
Read data “n” times in units of 512 bytes by means of the MVI-D2-2HRX read
instruction from the host controller to the MVI-D2-2HRX data carrier memory, at any
point in time. (However, the data quantity might be less than 512 bytes during the last
transmission).
From Host Controller to Data Carrier
•
Repeat writing of data with up to 512 bytes by means of the write instruction (20h).
•
Combine the MVI-D2-2HRX write instruction (25h) with writing from the MVI-D22HRX to the data carrier command (23h) or with writing and checking from the
MVI-D2-2HRX to the data carrier command (24h).
Write data with “n” times 512 bytes from the host controller to the data carrier buffer
by means of the MVI-D2-2HRX write instruction, before the data carrier arrives.
(However, the data quantity might be less than 512 bytes during the last
transmission).
On arrival of the data carrier, the data stored in the MVI-D2-2HRX data carrier buffer
are written on the data carrier containing the write data (with check) of the MVI-D22HRX (max. 7552 or 30976 bytes).
Setting the Data Format
Data Code (DCD)
Two types of characters are available for the data code: hexadecimal ASCII code and
one byte JIS code.
Enter one digit of an alphabetical ASCII character to select the data code.
•
Both (3Ah) and CR (ODh) can be used to write and clear data with one byte JIS
character.

This command reads data within a specific memory area of the data carrier (copy
source), which is located in the communication area of the read/write head and writes
into the memory of the data carrier (copy destination) which is located in the
communication area of the other read/write head.
Specify the number of the copy source's read/write head in the command as number
of the read/write head (ANT). (ANT = 0 corresponds to copying data from read/write
head 0 to read/write head 1. ANT = 1 corresponds to copying data from read/write
head 1 to read/write head 0.)
The maximum number of bytes that can be copied is 7552 or 30976.

Commands
9.4.5 Example for Application of the “Single Read” Mode
Transmission with a Stopped Data Carrier
(Communication startup system: Command stay system)
This method is the most reliable transmission method, since the position of the data
carrier in relation to the read/write head is fixed.
1. The commands from the host controller to the MVI-D2-2HRX are stored in
advance.
2. The data carrier must be mounted on the pallet so that it can be transported with
the conveyor device.
3. When the pallet reaches the calculated position, the pallet recognition switch is
activated and switches the MVI-D2-2HRX trigger input ON. The pallet is stopped
by a stopper.
4. With the pallet arrival signal, the read/write head starts communication with the
data carrier.
The optimum condition is when the data carrier and the read/write head face each
other directly in the stop position.
If the pallet is stopped only by a stopper, it may move backwards during the
transmission procedure, and the data carrier on the pallet may come outside the
transmission area of the read/write head. Therefore, a stopper is required in order to
prevent the pallet from moving backwards.
Transmission with a Moving Data Carrier
(Communication startup system, command stay system).
This system is suitable for mounting parts, which are moving on the belt conveyor.
The system shortens the clock time.
1. The transmission commands from the host controller to the MVI-D2-2HRX are
stored in advance.
Date of issue
03.05.2001
2. The data carrier must be mounted on the pallet so that it can be transported with
the conveyor device.
3. Install proximity switches just before each arrival position at the work place. After
the proximity switch has responded, switch the trigger input ON (the data carrier
should be within the transmission area of the read/write head).
4. On arrival of the proximity switch signal, the read/write head starts communication
with the data carrier.
5. Before the pallet reaches the working station, the read/write head should already
have finished exchanging data with the data carrier.
Subject to reasonable modifications due to technical advances.

IDENT-M System V
Commands
The transmission should be completed before the data carrier comes out of reach of
the read/write head's transmission area. In order to provide sufficient tolerance to
complete the transmission, the relation between the data carrier movement and the
required transmission time to the data carrier (including retry time interval in the case
of a transmission error) must be taken into account. Then the time-limit for the
transmission has to be set in the memory address 9000hof the MVI-D2-2HRX.
(Example for transmission with a moving data carrier)
1. The proximity switch detects the pallet (data carrier), which passes position A
(within the transmission area) and switches the trigger input ON in order to start
the transmission.
2. The read/write head ends the transmission before the pallet passes position B.
3. Place the working station after position B.

Commands
9.4.6 Example for the Use of the “Auto Read” Mode with Unlimited Data Carrier
Detection Time
The timer starts the transmission:
1. When the data carrier enters the transmission area, the read/write head
automatically starts the transmission to the data carrier.
2. On execution of the transmission, the host controller starts the time-counter.
3. After a specific interval has passed (time out), the MVI-D2-2HRX automatically
starts the next transmission in the “auto read” mode.
The previous data carrier should come out of the transmission area of the read/write
head before timeout is reached. Set the previous data carrier's ID code to “ID code
allocated non-function”.
Arrange in such a way, that the next data carrier does not come out of the
transmission area while the timer is still counting.

IDENT-M System V
Commands
In the Case of a Continuous Start
While the transmission conditions are met, always set to “auto read”.
The timer starts the transmission:
1. The automatic function start signal of the device, starts the first transmission
using the “auto read” function.
2. When the data carrier enters the transmission area, the read/write head
automatically starts the transmission to the data carrier.
3. After the transmission is completed, the system starts the next transmission in the
“auto read” mode.
The system should be arranged in such a way that no problem occurs when a
transmission is performed more than once with the same data carrier. When problems
occur during repeated transmissions, ID codes for each data carrier should be written.
Execute the function with “ID code allocated non-function”.
This function is even available when the speed of the data carrier (workpiece, pallet
etc.) varies. In the case of a conditional start, the system starts the transmission in the
“auto read” mode with a specific signal (specific condition).
1. The system starts communication with “auto read” by means of the pallet scan
signal.
2. When the data carrier enters the transmission area, the read/write head
automatically starts the transmission to the data carriers.
3. After the transmission is completed, the system ends “auto read” and waits for the
next pallet scan signal.
The previous data carrier should come out of the read/write head's transmission area
before the pallet scan signal is entered. Set the previous data carrier's ID code as “ID
code allocated non-function”.
This function is also available when the speed of the data carrier (pallet etc.) varies
(example of a conditional start).
1. The read/write head starts the transmission with “auto read”, after the pallet has
passed the signal on position A.

Checking the Battery Life
Check the service life and the battery voltage of the battery integrated in the data
carrier by means of the transmission function between the host controller and the data
carrier (checking the battery life of the data carrier and self-diagnosis of the data
carrier).
•
If an error is found during the test, the data carrier sends an error message to the
host controller (service life alarm or low battery voltage alarm, see page 185).
Error code

Explanation
3A
Low battery voltage alarm
Voltage level of battery is too low
3B
Battery service life alarm
Battery service life exceeds 100 %
In case the battery functions properly, the data carrier sends an acknowledgement
containing the battery utilisation rate. In case the battery voltage is too low, the
corresponding error message is added to the acknowledgement. This is also done, in
case other communication operations are conducted at the same time (see page
185).
Be sure to substitute the data carrier immediately, in case one of these errors occurs.

Maximum Cable Length
The supply voltage from the MVI-D2-2HRX to the read/write head drops
proportional to the cable length. Determine the conductivity and the extension
cable length by means of the calculation example given on the next page, in
order to ensure that the voltage drop is less than 1 V.
c.
Extension from 200 m to 1,200 m
Use cables with a core cross section of about 0.5 mm2. In this case, the read/
write head should not receive any voltage from the MVI-D2-2HRX. In order to
provide the read/write head with voltage, a 15 VDC power supply should be
installed alongside the read/write head. In any case, it is necessary to connect
24 VDC to the external power supply connection of the MVI-D2-2HRX. The
cable between the read/write head and the MVI-D2-2HRX is only used for data
transmission, not for power supply.
