Change the default address 248 the softstarter with the keypad (Fieldb Addr)
and enable the fieldbus communication Fieldb Ctrl=Yes ). The baud rate mapped the slave address, e. 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.
