My name is Mike Webster. I work for Martint Enviromental. We are working on a project that requires a pumping PID block using the micrologix 1500. I can get the PID block to work in the SLC rack but last time I tried to use the PID block in the micrologix 1500, I had errors and aborted the mission. Does any one have sample code of a PID pump application. Like a Flow meter to the PLC controlling a AC drive. Mike Webster mike@martintenvironmental.com
