Implementing a Basic Application

General Case The table below illustrates the operation of a pushbutton connected to the smart relay. Pushbutton BP1 is connected to input I1 and lamp L1 is connected to output Q1 on the smart relay.

Off delay		Operating
Electrical diagram	Smart relay symbols	Electrical diagram	Smart relay symbols
Pushbutton	I1 = 0		I1 = 1
normally open	i1 = 1		i1 = 0
Pushbutton	I1 = 1		I1 = 0
normally closed	i1 = 0		i1 = 1

Note: The reverse function may be applied to all of the contacts in a ladder diagram, whether they represent outputs, auxiliary relays or function blocks.
