Hi,
I am using the LogixPro Simulator to learn plc programming. Have
trouble understanding the logic for the door limit switches.
Can anyone help?

Hi smithc

From your question I believe this should answer it,

An Examine ON statment must "ON" to be true, --] [--
An Examine OFF statment must "OFF" to be true, --]/[--

N.O. switch in a open state,
Examine ON = False
Examine OFF = True

N.O. switch in a closed state
Examine ON = True
Examine OFF = False

N.C. switch in a open state
Examine ON = False
Examine OFF = True

N.C. switch in a closed state
Examine ON = True
Examine OFF = False

All conditions must be true for an output to be true (Energised)
