4-20mA TO propotional valve control

It looks like you have V1 and V2 defined in 2 places.

You have them defined in PLC_PRG as local variables

AND

You have them defined in the I/O table.

Because of this, when you are writing to V1 or V2 within you PLC_PRG, you are only setting the values of the local variable.

Try to comment out V1 and V2 definitions in PLC_PRG and see if that works.
