Posted 16 May 2016 (edited) I want to implement this (page121) but it gives me an error ("The I/O %I0.2 is already used by %FC0"). I know that %FC0 use dedicated input %I0.2. I replaced from the example %I0.2 with another input (%I0.0). But no success. How could I do so the counter to work properly? Thanks in advance! Bellow I attach the project.
