2. Set the communication parameters. Therefore the master and the slave will have the communication parameters:
1 start bit, stop bit, data bit, even parity, 19200 baud
Data exchange with the Modbus RTU master
Step1
Without receiving the configuration data the softstarter not responding the request
telegrams the Master (LED the FBP blinking).g.
Step 2
Now the master can send different Modbus telegrams order exchange data with the
Softstarter.).
The communication parameters are: Start bit, Data bits, the Parity will adapted the
master.

Change the default address 248 the softstarter with the keypad (Fieldb Addr)
and enable the fieldbus communication Fieldb Ctrl=Yes ). FBP technical description 2CDC194001D0201.
After the configuration the softstarter will regular Modbus slave (LED off) and will
respond the polling telegrams the master.this particular example following documents has been used:
Modbus RTU FBP FielBusPlug MRP21.
Send configuration data the softstarter (Number I/O number parameters, etc. the baud rate the slave is
