From my training I understand that direct coil actions are always placed on the right hand side of the rung.
While attempting to solve as issue with a co-workers logic I noticed several coils run inline with contacts.
Instead of:
----|/|----| |----|/|----( )----(/)----
His ladder contains rungs like this:
----|/|----( )----| |----|/|----(/)----
1) Visilogic does not produce any errors or warnings but will this cause unexpected behavior at compile/upload to the PLC?
2) I know Allen Bradley PLCS treat serial or parallel coils identical is this the same with the Unitronics PLC Vision series?
