Setting of the Modbus address
Disconnect module from the power supply.
Set Modbus address "
50 " (address selector switches X10 and X1).
Connect Modbus to 100 ohm terminating resistor.
Supply power to module.
Configuration of the communication parameters of the Modbus interface
Menu 5-3-1 Modbus Configuration
MODBUS ID:XXXXX Description Input
Parity Selection of the parity for the Modbus communication → continue to screen 5-3-1-a
Baud rate Selection of the baud rate for the Modbus communication → continue to screen 5-3-1-b
Screen 5-3-1-a Configuration of the parity
MODBUS ID:XXXXX Description Input Default
even Parity is even √ √
odd Parity is odd
none No parity is set
Screen 5-3-1- b Configuration of the baud rate
MODBUS ID:XXXXX Description Input Default Dim.
9600 Baud rate is 9600 √ Bd

7.2.6.2 Terminal assignment of the Modbus relay module 230 V AC
The controller can be extended in each case by 4 relay outputs (4 x 0..230 V DC) with the Modbus relay
module from Metz.
DANGER
Warning about dangerous electrical voltage! Danger to life - Danger of electric shock! If supply
voltage is connected to the analogue outputs, there is a risk of personal injury as the RS485 interface
is not galvanically isolated from other system components (e.g. pressure transmitters). Furthermore
this will destroy the controller!
BEFORE connecting and disconnecting, it must be checked that no voltage is present at the 230 V AC
relay outputs! Low voltage and safety extra-low voltage must not be applied together at the relay
outputs!
