I have a Micrologix 1500. Need to control with PID for digital outputs open/close. There is no SRTP function (Split Range Time Proportional) in the 1500. Anyone have code out there to do this?
Thanks
 
Use a couple timers, one for the frequency and the other for the duty cycle. Move the PID output into the duty cycle timer .pre
