The communication parameters are: Start bit, Data bits, the Parity will adapted the
master.
Step 2
Now the master can send different Modbus telegrams order exchange data with the
Softstarter. 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).

. Set the communication parameters.
After the configuration the softstarter will regular Modbus slave (LED off) and will
respond the polling telegrams the master. Set the softstarter address and field bus communication.).
Send configuration data the softstarter (Number I/O number parameters, etc.02
For other versions software RED marked figures this example will change
Softstarter settings
1. The baud rate mapped the slave address, e.g.Softstarter software version: Ver 05. the baud rate the slave is
19200.02.
Change the default address 248 the softstarter with the keypad (Fieldb Addr)
and enable the fieldbus communication Fieldb Ctrl=Yes )
