Hi, I'm new to this forum and relatively new to AB PLC's. I'm trying to setup a PID Loop to work with an HMI. I understand that SWM is the preferred manual control method. My problem is that when I set the "PID1.SWM" bit it immediately resets. Nothing in the logic is resetting it and I have tried forcing the bit on in the logic. I'm using a 1769-L36ERM processor with Logic Designer 5000 v24.
