Program Description

RUNG 0000

Start/Stop Push Button is connected with one shot rising bit with the output memory bit.

RUNG 0001

Previous rung output bit and Lamp output bit are connected in X-OR gate logic to make the condition possible. Interlocking of output bit is used to turn the output ON/OFF in different condition.


The above explained ladder logic for lamp turn ON/OFF using single push button is for example only. We can use this example program to understand the working of Push Buttons, one shot rising in AB PLC.
