Hi Yosi,
I used the same protocol before in a Wago 750-880 PLC and it worked. But I was using the old Wago Cosedys Software. Now I am using e!****PIT which use e!RUNTIME (codesys 3).
I am suing the Modbus Master Manager to modbus address my variables. For example, I have a WORD var that I choose to be a R/W register then e!****PIT automatically assigned 32000 to that variable.
Do you know what memory should I access and what address number should I use?
Also, an interesting fact. I tried to change the value of that variable in the PLC and defaults back to 0
Thanks in advance
