After the configuration the softstarter will regular Modbus slave (LED off) and will
respond the polling telegrams the master.g.this particular example following documents has been used:
Modbus RTU FBP FielBusPlug MRP21. the baud rate the slave is
19200.

.). 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).
Softstarters PST installation and commissioning manual SFC132003M0201, June 2007
Softstarter software version: Ver 05. Set the softstarter address and field bus communication. FBP technical description 2CDC194001D0201.
Change the default address 248 the softstarter with the keypad (Fieldb Addr)
and enable the fieldbus communication Fieldb Ctrl=Yes ).

1.
The communication parameters are: Start bit, Data bits, the Parity will adapted the

Step 2
Now the master can send different Modbus telegrams order exchange data with the
Softstarter.
Send configuration data the softstarter (Number I/O number parameters, etc. Set the communication parameters. The baud rate mapped the slave address, e
