Well, well, well, this is the season for mad Logo enquiries!

What do you know. Siemens has actually put a single block function called a Pulse Relay in the Logo that does exactly this.

One block, one input, one output, what more do you need? (Oh, being Siemens, they've added two more inputs, R and S, that allow you to override the action of the trigger input and have a set or reset action as well!)

Regards

Ken

Actually you can also do this on a one line plc program using OMRON nano PLC (ZEN).

IO Q0

IO= input from a single switch
Q0= alternate operation function of the CPU unit output relay

That's not the way we are used to help people. In fact, giving ready-made solutions isn't helping people at all. Helping people is to tell them where to find sufficient info to solve their problems themselves.

One tip: what you're needing here is a toggle fucntion, also known as flip-flop. There's a lot of info te be found here if you use the search function and one of these two given words.

Kind regards,
