I have been programming PLC's for 10 years,and was ask to program a "SINGLE" toggle input "momentary input" to control an "SINGLE" output(no big deal so far)except for the same "SINGLE"toggle input "momentary input" is to turn on and off the same "SINGLE" output,hence "can not use counters". Control Description(1), press the "SINGLE" toggle "momentary input" and instantly the "SINGLE" output is true or press the "SINGLE" toggle and the "SINGLE" toggle remains press for as long as desired and the "SINGLE" output is instantly true and remains true after the release of the"SINGLE" toggle.Control Description(2),Knowing the "SINGLE" output is now true after reading (control desciption 1)the same "SINGLE" toggle "momentary input" is to turn off the same "SINGLE"output. The pressing action of the "SINGLE" toggle desrcibed in (contol description 1) applies in (control description2). Please forward and/or post your advice.
