Programming a physical Momentary switch to be a maintained one.

How would one program a momentary button switch to be a maintained one with ladder logic. I have experimented with the different coil types to no avail. Some help would be greatly appreciated

    I'm not sure if this is what you're looking for, but if you want to maintain the signal until a reset signal is received, you can use a latching relay - either an RS or SR function block.

    You could implement the functionality of these FBs yourself, but it is probably easier to use the FBs.

    Cheers Martin, exactly what I'm looking for.
