25. MODBUS VARIABLES
The control has the following modbus configuration by default:
• Baud rate: 9600
• Parity: EVEN
• Data bit: 8
• Stop bit: 1
• Device ID: 1
To configure the Modbus communication according to your requirements, you must modify the following parameters:
Parameter VALUE Function

0 Baud rate 4800 bit/s
1 Baud rate 9600 bit/s
2 Baud rate 19200 bit/s
3 Baud rate 38400 bit/s
H125
0 Parity NONE and stop bit 2
1 Parity ODD and stop bit 1
2 Parity EVEN and stop bit 1
3 Parity NONE and stop bit 1
