Hi,
Have been trying to create some logic for controlling a conveyor-model with help of LabVIEW and 3 myDAQ's, instead of the usual PLC-setup.
We haven't come further than a few functions, then everything became sluggish.
The model consists of two soleniods pushing out plastic-rings, two conveyor-belts and some other sorting mechanisms.
When the plastic-ring passes X1 (see program below) solenoid Y1 should push out momentarily, but in our program it will be hitting in 1/3 attempts. The other 2/3 attemps comes with a delay of a second or two.
All in all, it seems that the combination of LabVIEW and more than one myDAQ is way to unstable and slow for replacing a PLC.
(Has been testing on two different Intel I5-computers, and all atempts are ideling CPU-load).
The program beneath contains a couple of subVI's for minimizing the space of easy logic, but we have tried to direct connect the inputs to the outputs, while the result remain the same.
