Hello Everyone!
Our customer has FX3G PLC with FX2N-16EYR expansion module, FX2N-8AD Analog Input Module and two FX3U-4AD-TC-ADP module. How the system works is that thermocouples that connected to the TC-ADP and FX2N-8AD module read sealer temperature. If the temperature read is below the set point, then the PLC turn on the heater through the FX2N-16EYR.
The problem we encounter is that the sealer temperature has passed the set point, but the PLC still turn on the heater. I've checked the program and there is nothing that could caused this problem. Can someone help me find the solution for this problem.
I attach the part of the program that showed the logic.
Thank you
