Hello everyone. Can anyone tell me why the set coil works like a regular relay, and does not remain on when the input signal disappears?
I tried sending %B0 to the internal relay. The result is the same.

It been a long time since I have used classicladder but I think you need to link the set coil to a contact like in this example:
So you would connect your '%Q0' Output to the 'toggle' contact. (Like 'reset' in the example above but without the 'Time-off' block.)

I made a diagram. Here's how it works. When power is applied to the set input, the coil turns on and remains on, but it does not glow red, but its additional contacts glow. Accordingly, powering the reset input turns it off.
