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).Softstarter software version: Ver 05.
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.
1SFC132047M0201 11
.g. Set the communication parameters.03
For other versions software RED marked figures this example will change
Softstarter settings
1.03.
After the configuration the softstarter will regular Modbus slave (LED off) and will
respond the polling telegrams the master.
2.). Set the softstarter address and field bus communication. The baud rate mapped the slave address, e.
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 ). the baud rate the slave is
19200
