Hi there and happy 2013!
I was given a Modicon 984 printout. The file name of the .PDF file contains the string "Modicon 984 Proworx". I am attaching page 1 of said .PDF listing.
My question is: what is the meaning of the "N" letters preceding some of the normally open or normally closed contacts?
I am aware of positive and negative transitions, but I thing they would print as ]P[ and ]N[; plus, I don't think it makes too much sense to program more than one transition in series (the chance of capturing two transitions in the same scan must be close to nil).
I have been reading through Modicon manuals found online but could find no reference to the "N" letters.
Thank you,
Saulo35
