Hi there, I'm almost there with a small project to control a 0..10V lamp via my LOGO. I have two push-buttons, UP and DOWN. Both should vary the light accordingly when pressed longer than 0.5 seconds and switch ON (for UP) and switch OFF (for DOWN) if pressed shortly (<0.5s). I've found most of this program in this forum so and I'm very thankful for it. Everything works as expected but the ON button. I can't find the way to make the light switch ON fully (value = 100) when pressed shortly. B011 is the block that sets the dim level (0=OFF ...100=full ON). A long press (> 0.5s) "DOWN" makes B011 decount slowly (good!). When I short press (<0.5s) "DOWN", blocks B001/B002/B007 reset B011 that will switch the light OFF. A long press of "UP" makes B011 count up and the light level rises slowly (good!). And now my problem: how do I make a short press of "UP" to set B011 to 100? B008's output (="set light to 100") is unconnected because I don't know to what or where I should connect it.... Thanks for any suggestion.

Maybe an analog counter would be a better solution for a dimmer, see attachment. The speed for counting up or down may be slowly in a simulation, try it in a Logo controller. If 0.01s is not fast enough in real time, then change maximum value from 1000 to e.g.100 and insert an amplifier with gain=10 between dimmer value and AQ1.
