CAUTION
The communications bus interface functionality is disabled when the direct configuration port is en-
abled. The parameter "Direct parametr." must be configured "NO" to re-enable the communication bus
interface (refer to "Direct Configuration (from Version 3.0xx)" on page 34).
NOTE
These screens and all related screens are only displayed if the particular communication option is in-
cluded on the control unit. If the individual communication protocol is not included, the related
screens will not be displayed.
NOTE
A description of the communication protocols may be found in Appendix D of this manual.

Data word address in receiver (e.. g. PLC).
Screens for Protocol Profibus DP Slave (
Option SU
)
Device number
Profibus 000
Device number profi-bus DP slave
0 to 126
Device number for the profi-bus DP slave.
Screens for Protocol Modbus RTU Slave (
Option SU/SB
)
Device number
MOD-Bus 000
Device number Modbus RTU Slave
1 to 255
Device number for the Modbus RTU Slave.
Baudrate
0000
Baud rate Modbus RTU Slave
1,200 / 2,400 / 4,800 / 9,600 / 19,200 Baud
The baud rate of the Modbus RTU Slave is defined here.
Parity
none
Parity Modbus RTU Slave
none / even / odd
The parity of the Modbus RTU Slave is defined here.
Stopbits
one
Stop bits Modbus RTU Slave
one / two
The number of stop bits of the Modbus RTU Slave is defined here.
Delay to send
MOD-Bus 00.0ms
Waiting time transmission after read request
0.2 to 50.0 ms
After the read request by the master, the minimum waiting time before transmitting
the answer is configured here. This allows the controller to adjust the response time
to the master so that it can process the answer.
