FWD_IN with N.O. Switch

FWD_IN with N.O. Switch

I have a N.O. limit switch sensor In normal mode it outputs ‘0’ and goes to '1' when the limit is reached.

How can I used it with FWD_IN?
=======================================================
The command INVERT_IN will do what you want.  For example with the switch connected to input 10:

INVERT_IN(10, 1)
FWD_IN = 10
