Fast commissioning / operating principle
3.3.1
Connecting the Leuze device
 To connect the Leuze device to the internal RS 232 device interface, open the housing
of the MA 235i and guide the corresponding device cable (see chapter 14.7, e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Set CANopen device address
By setting the CANopen address, the MA 235i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the CANopen
with its specific address and that it is initialized and queried by the PLC.
The CANopen permits an address range from 0 to 127, the MA a range from 0 to 99. Other
addresses must not be used for data communication.
 Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).

Set CANopen baud rate on the MA
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 235i possible.
 Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.

Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 235i, the device selection switch is queried and the gateway
automatically sets itself to the Leuze device.
Connecting functional earth FE
 Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connection.

Connecting the power supply and the bus cable
 Ideally, use the ready-made cables listed in chapter 14.5.3 to connect the gateway to the
power supply via the PWR IN connection.
 The ready-made cables listed in chapter 14.6.4 are preferred for connecting the gateway
to the fieldbus via the HOST / BUS IN connection.
 If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.

Starting the device
 Apply the supply voltage +18 … 30 V DC (typ. +24 V DC); the MA 235i starts up. 
The PWR LED displays that it is ready for operation.
MA 235i on the CANopen
 Install the EDS file corresponding to the MA 235i in your planning tool/the control.
Notice!
You can find the EDS file at: www.leuze.com
After all parameters have been set in the planning tool/control, the download to the MA 235i
takes place. The set parameters are now stored on the MA 235i.
Afterwards, all MA 235i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 235i possible.
Detailed information can be found in chapter 12.

General Information to the connector units
The modular interfacing unit of the MA 2xxi family is a versatile gateway for integrating Leuze
RS 232 devices (e.g., BCL 22 bar code readers, RFID devices, RFM 32, AMS 200) in the
respective fieldbus. The MA 2xxi gateways are intended for use in industrial environments
with a high protection class. Various device versions are available for the conventional fieldbuses. With a stored parameter structure for the connectable RS 232 devices, commissioning could hardly be simpler.
4.2
Characteristics of the connector units
A special characteristic of the MA 235i device family are three function modes:
14
1.
Transparent mode
In this function mode, the MA 235i functions as a pure gateway with automatic communication from and to the PLC. Absolutely no special programming by the user is
necessary for this purpose. The data is not buffered or stored temporarily, however.
Instead, it is "passed on".
The programmer must make certain to retrieve the data from the input memory of the
PLC at the right time, as it is otherwise overwritten by new data.
2.
Collective mode
In this operating mode, data and telegram parts are temporarily stored in the memory
(buffer) of the MA and sent to the RS 232 interface or to the PLC in a telegram by means
of bit activation. In this mode, however, all communication control must be programmed on the PLC.
This function mode is helpful, for example, for very long telegrams or when one or
more codes with long code lengths are read.
3.
Command mode
With this special operating mode, it is possible to use the first bytes of the data range
to transmit predefined commands to the connected device by means of bit activation.
For this purpose, device-dependent commands (so-called online commands) are predefined via the device selection switch, see chapter 16 "Specifications for Leuze end
devices".

Device construction
The MA 235i modular interfacing unit is used for interconnecting Leuze devices, such as
the BCL 8, BCL 22, etc., directly to the fieldbus. This is accomplished by transmitting the
data from the Leuze device via an RS 232 (V.24) interface to the MA 235i where a module
converts it into the fieldbus format. The data format of the RS 232 interface corresponds to
the standard Leuze data format.

Connection of a Leuze device (BCL, RFI, RFM, VR) to the fieldbus
The cable of the respective Leuze device is guided through cable bushings with PG cable
glands into the MA 235i and connected there with the PCB connectors.
The MA 235i is intended as a gateway for any RS 232 devices, e.g., BCL 90 with MA 90,
hand-held scanners, scales or for coupling a multiNet network.
The RS 232 cables are internally connectable using JST plug connectors. The cable can be
connected to the device using a stable PG cable gland which provide strain relief and protection against contamination.
With the help of adapter cables with Sub-D 9 or open cable end, other RS 232 devices can
also be connected.

Operating modes
For fast commissioning, the MA 235i offers an additional operating mode, the "Service
mode", in addition to the "Standard mode". In this operating mode, the Leuze device can,
for example, be configured on the MA 235i and the network settings of the MA can be
displayed. To do this, you need a PC/laptop with a suitable terminal program, as BCL-Config
from Leuze or similar.
Service switch
Select between "operation" and "service" modes with the service switch. You have the
following options:
Pos. RUN:
Operation
The Leuze device is connected to the fieldbus and communicates with the PLC.
Pos. DEV:
Service Leuze device
The connection between the Leuze device and the fieldbus is interrupted. With this
switch position, you can communicate directly with the Leuze device at the fieldbus
gateway via RS 232. You can send online commands via the service interface, configure the Leuze device using the corresponding BCL- BPS-, …-Config configuration
software and have the read data of the Leuze device output.
Pos. MA:
Service fieldbus gateway
With this switch setting, your PC/terminal is connected with the fieldbus gateway.In
doing so, the current setting values of the MA (e.g. address, RS 232 parameters) can
be called up via a command.
Figure 4.2:
Service-switch switch positions
Notice!
If the service switch is on one of the service settings, the CAN LED flashes on the front side
of the device, see chapter 8.1.2 "LED indicators on the housing".
Furthermore, on the control, the SMA service bit of the status bytes signals that the MA is
in service mode.

Bus topology
The CAN bus is a serial 2-wire bus system to which all participants are connected in parallel (i.e., using short stub cables). To avoid reflections, the bus must be terminated with a
terminating resistor of 120 ohm at each end of the trunk line. Terminating resistors are also
required for very short trunk line cable lengths.
If the MA 235i is the last participant in the trunk line, the trunk line can be terminated via
the M 12 bus OUT connection. For this purpose, Leuze electronic offers an M 12 terminating resistor, see chapter 14 "Type overview and accessories".
Bus line (trunk line)
For CAN, the maximum cable length of the trunk line is predominantly limited by the signal
propagation time. The multi-master bus-access process (arbitration) requires that the signals are present virtually simultaneously at all nodes/participants. Therefore, the cable
length of the trunk cable must be adapted to the baud rate.

Device description
Address assignment
Notice!
The participant-specific address for CANopen is also called the Node ID. Throughout this
handbook, the term "address" is used, which is identical to "Node ID".
Each participant connected to CANopen is assigned its own address (Node ID). Up to 127
participants can be connected to one network. The addresses of the MA range from 1 to
99. The address 0 is usually reserved for the CANopen master.
Notice!
The "Layer Setting Services (LSS)" function is not supported by the MA 235i. For this reason,
the address must be set manually. See "Switch for address selection in the fieldbus" on
page 40.
Baud rate setting
The MA 235i supports the following baud rates:
1 Mbit/s
800 kbit/s
500 kbit/s
250 kbit/s
125 kbit/s
100 kbit/s
50 kbit/s
20 kbit/s
10 kbit/s
The default setting of the gateway is "auto".
Notice!
The "Layer Setting Services (LSS)" function is not supported by the MA 235i. The baud rate
must be set manually. See "Switch for setting the baud rate" on page 40.

The gateway is set via the switch position on the Leuze device. If the switch position is
changed, the device must be restarted, since the switch position is only queried after
switching off completely and then restarting the device.
Notice!
In switch position "0", a distance of >20 ms must be maintained between two telegrams so
they can be distinguished from one another.
The parameters of the Leuze end devices are described in chapter 16.

Configuration
The MA 235i is configured using the EDS file via the device manager of the control. The
connected device is normally configured via the service interface of the MA with the help
of a suitable configuration program.
The respective configuration programs – e.g. for bar code readers the BCL-Config, for RFID
devices the RF-Config etc. – and the associated documentation are provided on the Leuze
home page www.leuze.com.

Structure of the fieldbus telegram
All operations are performed by control and status bits. Two bytes of control information
and two bytes of status information are available for this purpose. The control bits are a part
of the output module and the status bits are a part of the input bytes. The data starts with
the third byte.
If the actual data length is longer than the data length configured in the gateway, only part
of the data is transmitted; the remaining data is lost. In this case, the DL (data loss) bit is set.
The following telegram structure is used between PLC -> fieldbus gateway:

Modes

Modes
11.1
Functionality of the data exchange
The fieldbus gateway has two different modes that can be selected via the PLC:
• Transparent mode (standard setting)
In Transparent mode, all data is sent 1:1 and directly by the serial end device to the
PLC. It is not necessary to use status and control bits here. However, only data bytes
possible for one transmission cycle are transmitted - all others are lost.
The distance between two successive telegrams (without frame) must be more than
20 ms, since there is otherwise no clear separation between them.
ASCII characters are typically expected as data content; under certain circumstances,
the MA therefore detects different control characters as invalid characters in the data
range and truncates them. At 00h in the data range, the MA cuts the telegram off
because unnecessary bytes are also filled with 00h .
• Collective mode
In Collective mode, the data of the serial end device is stored temporarily in the fieldbus
gateway by toggling the CTB bit and is not sent to the PLC in blocks until prompted
to do so by the PLC.
On the PLC, a status bit (DEX) then signals that new data is ready for retrieval. This
data is then read out from the fieldbus gateway in blocks (toggle bit).
In order to distinguish between the individual telegrams on the PLC, in Collective mode
the serial frame is sent to the PLC in addition to the data.
The size of the buffer is 1 kByte.
Notice!
In Collective mode, the CTB and SFB bits are needed for communication handling via the
buffer. Telegrams that can also be completely transmitted in one cycle in Collective mode
(including data frame) go directly through. If PLC data is provided and transferred without a
state change of the CTB bit, it goes directly to the RS 232 interface with the set telegram
data length. Incomplete (incl. data frame) or faulty telegrams can cause error messages in
the connected device!
Combination with the Command mode is possible.
Data exchange in blocks must be programmed on the PLC.

MA 235i

Modes
11.1.1 Reading slave data in Collective mode (gateway -> PLC)
If the Leuze device transmits data to the fieldbus gateway, the data is stored temporarily in
a buffer. The PLC is signaled via the "DEX" bit that data is ready for retrieval in the memory.
Data is not automatically transmitted.
If no further user data is present in the MA 235i ("DEX" bit = "0"), the "R-ACK" bit must be
toggled once as read confirmation to release data transmission for the next read cycle.
If the buffer still contains more data ("DEX" bit = "1"), the next remaining user data present
in the buffer is transmitted by toggling the "R-ACK" control bit. This process is to be repeated
until the "DEX" bit returns to "0"; all data has then been removed from the buffer. "R-ACK"
must be toggled here again once more as a terminating read confirmation in order to release
data transmission for the next read cycle.
Used status and control bits:

R-ACK
11.1.2 Writing slave data in Collective mode (PLC -> gateway)
Writing in blocks
The data sent by the master to the slave is first collected in a "transmit buffer" by setting
the "CTB" bit (Copy to transmit buffer). Please observe that data provided is transmitted
directly by toggling the bit.
Afterward, the buffer is again empty and can be written with new data.
Notice!
With this function, it is possible to temporarily store longer data strings in the gateway
independent of how many bytes the used fieldbus can transmit at once. With this function,
longer PT sequences or RFID write sequences, for example, can be transmitted, since the
connected devices can, in this way, receive their commands (e.g., PT or W) in a continuous
string. The respective frame (STX CR LF) is needed to differentiate between the individual
telegrams.
Used status and control bits:
• CTB
• SFB
• W-ACK
Leuze electronic
MA 235i
53
TNT 35/7-24V
The data is then sent in the order received from the buffer to the connected Leuze device
via the serial interface with the command: "SFB" (Send data from transmit buffer). Please
don't forget the suitable data frame!
Modes
If PLC data is provided and transferred without a state change of the CTB bit, it goes directly
to the RS 232 interface with the set telegram data length. Incomplete (incl. data frame) or
faulty telegrams can cause error messages in the connected device!
Examples for the activation of a Leuze device
In the data part (starting at byte 2) of the telegram to the gateway, a "+" (ASCII) is sent for
activation.
This means that the hex value "2B" (corresponds to a "+") is to be entered in control or output
byte 2. To deactivate the reading gate, a "2D" (hex) must be used instead (corresponds to
a "-" ASCII).

Modes
11.1.3
Command mode
One specific feature is the so-called Command mode, which is defined via the output control
byte 0 (bit 0) ... and enables the control of the connected device per bit.
If the Command mode is activated (Command mode = "1"), no data is sent by the PLC to
the Leuze end device via the gateway. The data from the MA to the PLC is transmitted in
the selected operating mode (Transparent/Collective).
With the Command mode, it is possible to set various device-specific bits in the data- or
parameter field that execute the corresponding serial commands (e.g., v, +, -, etc.). If, for
example, the version of the Leuze end device is to be queried, the corresponding bit is to
be set so that a "v" is sent to the Leuze device with the <STX> v <CR> <LF> frame.
The Leuze end device also answers the gateway with data (e.g. bar code content, NoRead,
device version, etc.) in response to most commands. The answer is immediately passed on
to the PLC by the gateway.
Notice!
The parameters available for the individual Leuze devices are listed in chapter 16.
Command mode cannot be used with hand-held scanners.
Examples for the activation of a Leuze device
In Command mode, control or output byte 0.0 is to be set for activating the Command mode.
Only the corresponding bit (control or output byte 2.1) then needs to be set for activating
and deactivating the reading gate.

Commissioning and configuration
12.1
Measures to be performed prior to the initial commissioning
 Before commissioning, familiarize yourself with the operation and configuration of the
MA 235i.
 Before connecting the supply voltage, recheck all connections and ensure that they
have been properly made.
The Leuze device must be connected to the internal RS 232 device interface.
Connecting the Leuze device
 Open the housing of the MA 235i and guide the corresponding device cable (e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Set CANopen device address
By setting the CANopen address, the MA 235i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the CANopen
with its specific address and that it is initialized and queried by the PLC.
The CANopen permits an address range from 0 to 127, the MA a range from 0 to 99. Other
addresses must not be used for data communication.
 Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).

MA 235i in the CANopen system
 Install the EDS file corresponding to the MA 235i in your planning tool/the control.
Notice!
You can find the EDS file at: www.leuze.com
The MA 235i is configured in the planning tool/control by means of the EDS file. The MA 235i
is assigned an address in the planning tool, which then has to be set in the MA 235i via the
S1 and S2 address switches. Only if the addresses are the same between the MA 235i and
the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the MA 235i
takes place. The set parameters are now stored on the MA 235i.
Afterwards, all MA 235i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the S3 baud rate selector switch.
In a CANopen network, all participants have in principle equal privileges. Each participant
can initiate its data transmission independently. Here, the arbitration specified by the CIA
controls the access of the individual participants to the network. Generally, each CAN participant listens in on the bus. The transmission process is started only if the bus is not occupied
by another CAN participant. When transmitting, the current bus status is always compared
to the own transmitted frame.
If several participants start a transmission simultaneously, the arbitration process decides
which participant gains access to the network next. The individual participants are integrated into a prioritization scheme via their bus address and the type of data to be transmitted (index address of the data). Process data (PDOs) of a device are transmitted with a
higher priority than, for example, variable objects (SDOs) of a device.
The node address of the participant is another criterion for prioritizing a participant in the
network. The smaller the node address, the higher the priority of the participant in the
network.
Since every participant compares its own priority with that of the other participants at the
time of bus access, the participants with low priority discontinue their transmission activities
immediately. The participant with the highest priority obtains temporary access to the bus.
The arbitration process controls the access of all participants so that even participants with
a low priority have access to the bus.

Commissioning and configuration
12.4
Starting the MA 235i in the CANopen system
During starting up, the gateway runs through different states which are explained in brief in
the following.
INIT
The MA 235i initializes itself. No direct communication between the master and MA 235i is
possible. The CANopen master will transfer the MA 235i step by step into the "operational"
state.
In the status change from "INIT" to "PREOP", the TwinCAT or master writes the so-called
CANopen address (=station address) to the respective register of the CANopen slave
controller (here: MA 235i). This CANopen address is typically specified in relation to the position, i.e., the master's address is 1000, the first slave's address is 1001, etc. This is also
called the auto-increment method.
PRE-OPERATIONAL
The master and the MA 235i exchange application-specific initializations and devicespecific parameters. In the PRE-OPERATIONAL state, configuration is initially possible via
SDOs only.
SAFE-OPERATIONAL
The "Start Input Update" command puts the gateway into the "Safe-Operational" state. The
master produces output data, but input data are not considered. This means the MA 235i
does not return output data (=PLC input data) in SAFEOP. The gateway does not process
input process data (=PLC output data). Mailbox communication via CoE services is possible.
OPERATIONAL
The "Start Output Update" command puts the gateway into the OPERATIONAL state. In
this state, the MA 235i supplies valid input data and the master valid output data. After the
MA 235i has detected the data received via the process data service, the state transition is
confirmed by the MA 235i. If the activation of the output data was not possible, the gateway
remains in the SAFE OPERATIONAL state and outputs an error message.
12.4.1
Device profile
CANopen describes the characteristics of participants in so-called profiles. However, a
device profile for gateways is not defined.
The MA 235i is designed as a slave participant and cannot take on master functionality.

Commissioning and configuration
12.4.2 Object directories
All process data and parameters are stored as objects in the MA 235i. The object directory
of the MA 235i is the compilation of all process data and parameters of the gateway.
An object directory is structured such that some objects within a device profile are mandatory while others are freely definable and stored in the manufacturer-specific object area.
The objects are uniquely identified using an index addressing scheme. The structure of the
object directory, the assignment of the index numbers, as well as some mandatory entries
are specified in the CIA standard DS301 for CANopen.
EDS file
For the user, the object directory of the MA 235i is stored as an EDS file (Electronic Data
Sheet).
The EDS file contains all objects with index, sub-index, name, data type, default value,
minimum and maximum, and access privileges. That means the EDS file describes the entire
functionality of the MA 235i, and it is possible to adjust both the communication of the
gateway with the control and the RS 232 interface.
Notice!
The size of the input and output data is permanently set for CANopen: the MA 235i always
provides the process data for transmission in this form: 8 bytes Tx and 8 bytes Rx.
The EDS file has the name MA 235i.eds and is available for download on the Leuze home
page.
Vendor ID for the MA 235i
12.4.3 SDOs and PDOs
The data exchange in CANopen distinguishes between service data objects (SDOs), which
are used for transmitting the service data (parameters) from and to the object directory, and
process data objects (PDOs), which are used to exchange the current process states.
12.4.4 SDOs
By using SDOs, all entries of the object directory can be accessed. Within one SDO call,
only one object can be accessed at any one time. For this reason, a service data telegram
must have a protocol structure which describes the exact target address by means of
index and sub-index addressing. SDO telegrams place a part of the SDO addressing into
the user data area. Eventually, a user data area with a width of 4 bytes out of the possible
8 bytes of user data remains for each SDO telegram.
The target address always responds to SDO transfers.
In the following, the index and sub-index address of the MA 235i parameters and variables can be found in the individual object descriptions.

Detailed information on the device description file and the object directory can be

Commissioning and configuration
12.4.5
PDOs
PDOs are objects (data, variables and parameters) from the object directory compiled
(mapped) by the device manufacturer. A maximum of 8 bytes of user data from various
objects can be mapped into one PDO.
A PDO can be received and evaluated by each participant (node). The model is referred to
as the producer-consumer procedure.
Since there is no protocol structure in the telegram of a PDO, the participants in the network
for whom these data are intended must know how the user data in the data area of the PDO
are structured (which data are stored where in the user data area).
The exchange of process data is supported by the MA 235i via the following accesses:
• Event-controlled data transfer
Here, the data of a node are transmitted as a message whenever a change to the present state occurs.
• Polling with remote frames
The CAN node which has been defined as master in the network requests the desired
information via query (via remote frame). The participant which has this information
(or the required data) responds by sending the requested data.
• Synchronized mode
CANopen permits simultaneous querying of inputs and states of different participants
and the simultaneous change of outputs or states. For this purpose, one uses the synchronization telegram (SYNC) transmitted by a master.
The SYNC telegram is a broadcast to all network devices with high priority and without
data content. Generally, the master sends the SYNC telegram cyclically.
Participants working in synchronized mode read their data when receiving the SYNC
message and then transmits them immediately afterwards as soon as the bus permits
this (see explanation regarding arbitration process).
As the SYNC process can very quickly lead to high bus loads, another distinction is
made between "event-controlled synchronization" and a "timer synchronization".
• Time-controlled transmission
In this case, the transmission of a PDO is triggered when an adjustable time period
has elapsed. The time-controlled transmissions are set individually for each PDO via
the so-called "inhibit time" or an "event timer". The respective parameters can be
found in the objects 1800h to 1803h for the corresponding PDOs.
• Node monitoring
Heartbeat and guarding mechanisms are available for failure monitoring of the
MA 235i. This is particularly important for CANopen, as the MA 235i may not respond
regularly in the event-controlled operating mode. In case of guarding, the participants
are cyclically queried for their state via data request telegrams (remote frame). In case
of heartbeat, the nodes transmit their state themselves.
Heartbeat and guarding / life time are standard communication objects from the
DS301 CANopen specification. The corresponding objects here are:
- Heartbeat 1017h
- Guarding / Life time factor 100Ch and 100Dh

In this example, triggering occurs by means of a trigger button on the hand-held scanner.
The following codes for configuring the devices are necessary for these devices as well.
12.5.2 Specific features in the operation of an RFM/RFI
When using the MA 235i in connection with an RFID device, we recommend a data width
of at least 24 bytes to be able to transmit information to or from the reader in a telegram.
Shown here is a sample telegram for a write command in combination with an RFID device.
Notice!
Also note that all characters which are sent to a transponder are hex-encoded ASCII characters. Each of these (hexadecimal) characters is, in turn, to be handled as an individual ASCII
character and converted to hexadecimal format for transmission via the fieldbus.

Specifications for Leuze end devices
Serial interface and Command mode
The corresponding Leuze end device can be selected while configuring the fieldbus gateway
(see chapter 9 "Configuration").
The exact specifications for the individual Leuze end devices can be found in the following
sections and in the device description.
The corresponding serial command is sent to the Leuze end device in Command mode. To
send the corresponding command to the RS 232 device after activating the Command
mode in byte 0 (control bit 0.0), set the corresponding bit in byte 2.
The Leuze end device also responds to most commands by sending data, such as the bar
code contents, NoRead, device version, etc., back to the gateway. The answer is not evaluated by the gateway, but is instead passed on to the PLC.
For the BPS 8, AMS and hand-held scanners, a number of specific features are to be noted.
Notice!
Please note that Leuze only assumes liability for the function of Leuze products. When using
third-party devices, Leuze does not assume liability for the function of third-party devices!
16.1
Standard setting, KONTURflex (S4 switch position 0)
This switch position can be used with almost all devices, since a data frame is transmitted
along with it if necessary. A 00h in the data range of the control is interpreted as the end of
a telegram/invalid, however.
The distance between two successive telegrams (without frame) must be more than 20 ms
in this switch position, since there is otherwise no clear separation between them. If necessary, the settings have to be adjusted on the device.
Leuze measuring sensors with RS 232 interface (such as a KONTURflex Quattro RS) do not
necessarily use a telegram frame, which is why these are also operated in switch position 0.
