With only a single input available, I need a multi-function momentary push button switch to activate 2 different Qs. Press and Hold PB for 3 seconds to start Q1…press again to reset Q1 Press PB 3 times to start Q2…press a 4thtime to reset Q2 If PB is pushed only once or twice, reset counters after 10 seconds. My design works but seems overly complicated. Is there a better way? AttachmentMulti-Function PB.zip (220 Downloads) |

You found an interesting solution. Is it intended, that by two short presses followed by a 3 second press both outputs can be switched on? And that I than need to press once to switch of Q1 and an additional 3 times to switch off Q2? If I press the button more than 0.2s Q1 is switched on for a short time and switches off again... I've created another solution (without first looking at yours) that should not have those quirks but is even more complex :) AttachmentPB-Multi.zip (227 Downloads) |

Depending on the application it may be easier to use 2 different times, e.g. short<0.5s, long>1s and reset>3s, see example in attachment. Regards, Scorp AttachmentMultibutton.zip (223 Downloads) |

Thanks for the input and proposal. I've worked on revising my program over the past few days. It's still complex, but I'll accept my failure for a more elegant solution. Simulation and live testing seems to handle my requirements. 1) Press and HOLD momentary push button for 3 seconds to activate Q1 for 30 seconds. Press again to cancel Q1 timer. 2) Press momentary push button 3 times to activate Q2 for 3.6 minutes Press again to cancel Q2 timer. Function Block B008 resets Up/Down Counters after 3.6 minutes... IF operator presses PB only once or twice. AttachmentMulti-Function PB Ver2.zip (220 Downloads) |
