Hello,
I have a question about PLC application I am working on. http://thelearningpit.com/lp/doc/dl/dl-rl.html
I am on excersise number 1. I am stuck at this problem: If the Door is already fully opened, Pressing the Open Switch will Not energize the motor.
How do I not engerize the motor? I can not use latches for this problems.
I will use an AND logic with the both limit switches to determine if the door is fully open. Then determine how to de-engerize the motor. But how will I not engerize the motor.
I can only use the basic instructions for this problem.
Any hints will be great!! Thanks alot.
