Question

I am looking for help with a PLC lab using LogixPro that will perform the common electrical function of controlling a light from two different locations (example: a long hallway where there is usually one light switch at each end).

Each switch can control the light on and off. The program should be set up so that if both switches are ON or if both switches are Off, then the light will go ON, and it will go off otherwise. The light switches are toggle switches and there is only 1 light.
