Interrupts based on conveyor distance [PickMaster 3]

PickMaster
1

I have an application where I want to pulse a recurring output based on the distance that a conveyor has travelled. This is the same functionality that is used to control the doTrigVis# output in Pickmaster.

Is there a way to have a second output on the same conveyor with a different spacing either through Pickmaster or through a RAPID interrupt?

Hello,

It sounds quite difficult to use this kind of function with the existing equipment DSQC 377. You can ofcourse read the position from the encoder, but there are a few problems with that.

  • You cannot poll this signal to often without risking that the system gets overloaded
  • Since you cannot poll to often you will not have so accurate position readings
  • The counter resets after every 10 m that the conveyor travels

If the conveyor travels continously you can make time offsets to the trig signal but this is not so accurate and you will not be able to use this if you are using start/stop functionality on the conveyor.
