Wago Modbus

Recommended Posts

I have a GeoBrick Drive and a Wago 750-342 Modbus Field coupler. On the Wago Rack I have 7 4pt Output cards for a total of 28 outputs. Then I have 1 4 pt input card.


My problem is that I have complete control of the outputs, but I cannot find the address that lets me read the inputs.


Below is a copy of Modbus setup saved file. I have added some M Var definitions at the bottom to show what addresses I am using for inputs and outputs.


M5003-M5005 are my outputs that work no problem.

M5006 does not read the inputs.


What address should my inputs be at?
