  2. This logic works for (MI 3) values between 1-5 minutes, but after that the timer will always be preset to about 5 and a half minutes. I'm assuming this issue has to do with the timer not having enough bits? I want to be able to store preset values ranging from 1-360 minutes, any way to do this? PLC is a V570. Thanks.
  3. Hi, I have a very high speed air cylinder that uses a laser sensor to give constant position feedback to the PLC. The PLC then sends out an analog output signal to a directional control valve depending on where the cylinder is in its current stroke. The goal is to extend the cylinder to a certain set point and right when it reaches the set point I want the cylinder to stop. The issue is because of the extremely high cylinder speeds, the current cylinder position undergoes a big change after the PLC has already finished updating the inputs to memory. Also by the time the PLC updates the ou
