My question is in regard to the XIO, XIC symbols for Allen-Bradley ladder logic programming.
Basically, When an input or output is on, is it shown by a N.O. set of contacts?
Then when it is off, it is shown by a N.C. set of contacts?
So, XIO=ON and XIC=OFF.
Not electrically, where N.C.= on and energized, and N.O.= off and de-energized?
-It’s been a while since I last programmed and I’d appreciate it if someone could advise me.
