Hello guys,
I am new to this plc programming(only 2 months), so help me out here,
Can you tell me the how to use ladder logic for following operation.
In this application I have a single push button in the panel as a input to the PLC.
My operation should be as follows,
1) When I press the push button first time the PLC should be in a stand by mode where no process will be executed.
2) When the push button is pressed second time the PLC should go in a manual mode.
3) When third time the push button is pressed PLC should go to auto mode.
And again when i press the same push button PLC should go to step1.
Also there should be a time delay each time when the push button is pressed.
