    HELP! complex pulse using ladder logic & timers

    TY everyone for all your responses. Turns out the logic using nested timers actually does work with the TECO SG2 PLC. It does NOT display the complex pulse using the PC interface software (which is all I was using to validate the concept when I posted originally). Apparently the only way to...

    HELP! complex pulse using ladder logic & timers

    TY for the suggestion about counters. I hadn't thought of combining counters with flash timers. However, I'm unsure where to put counters in the ladder logic to turn flash timers on/off. About the pulse schedule not matching the ladder logic & what I really want. What I want is the pulse...
