Unity have different program scan than old modicons.

Unity have scan from left to right then down.

Old modicons from up to down and then to right.

This means that you probably also need to move your zeroing measrument by valve closing under GT block.

Otherwise you still have reading on Unity if input is over 100 but there is also close_valve input on "1" state.

Doh, there is negated input also
