i gave the expire binding a try and made the following item:
Switch TestSwitchQ6 "Test Switch Q6" {plclogo="Logo2:VB204.1" , expire="0s,command=OFF"}
sitemap:
Switch item= TestSwitchQ6 mappings=[ON="Light"]
this makes it behave like a pushbutton, with this Logo! program:

i can now either push the button on openHAB or on the wall to get the light on or off.
But the status of the light is not shown in openHAB…
i can get the status of the Logo! output Q6 with:
Switch ReadOutputQ6 {plclogo="Logo2:Q6"}
but this gives me another item…
i read rossko57’s post, but, maybe it’s me being a beginner, i don’t know how to create a button for that:
or if you follow that thread:
i google it and read the item description, but i wasn’t able to find a solution yet…
maybe someone could point me to the right direction or post some example code?
