Communication via Modbus
5.4 Configuring the Modbus communication module
The parameters of the Modbus communication module can be adjusted on the front
face using the adjustment dials and selector:
- Modbus address
- Parity
- BAUD rate
- 120Ω resistance
Note
The Modbus communication module has a 120 Ω resistor to integrate a terminating
impedance into the Modbus chain. This resistor can be activated/deactivated by the
120Ω selector.
Modbus address setting Default setting
1 to 99 using adjustment dials x1 and x10 1
Parity setting Default setting
None – Odd - Even Even
Note
Setting the parity includes automatically managing the automatic adjustment of the
number of Stop bits.
None : No parity, 2 stop bits.
Odd : Uneven, 1 stop bit.
Even : Even, 1 stop bit.
BAUD rate setting Default setting
4800 – 9600 – 19200 - 38400 19200
120 Ω setting Default setting
ON - OFF OFF
