Dear Sirs/Madams
Recently, I received an technical question from my customer regarding of Allen Bradley HMI.
Allen Bradley HMI (PanelView 2711-TC1) is possible to write "I" address of Allen Bradley PLC(PLC 5/40 and SLC 540) without I/O module attached.
I am not sure this is true or not.
I guess this works for testing PLC ladder program (Emulator).
I just want to confirm whether it is true that Allen Bradley PLC accepts a Input command from Allen Bradley HMI?
As far as I know, Input without I/O module cannot be turn on because it is refreshed by PLC.
I am looking forward to hearing from you soon.
