I Attempt to read TWIDO's variables values but I can't. I suppose that is because my Items' definition is wrong.

I use This one: MODBUS01:1%!MW100, but the OFS Simules the value of that item.

PLease if somebody can help me.
Thanks for your answer.

the correct definition for a register read from TWIDO in OFS is:
>ALIAS!adress< ex: MODBUS01!%MW100 read the register %MW100 from Alias MODBUS01 = TWIDO.

It can be problem on Twido side or in the Modbus driver side !
Do you use the programming cable or RS converter?

Best regards!
