PID control using Micrologix 1000
PID control using Micrologix 1000
(OP)
I have a refrigeration project that requires temperature control using PID and a Micrologix 1000. Does anybody know if there is somewhere I can obtain the ladder logic to create a PID algorthim in the Micrologix 1000.

How you will perform the P (proportional) part of regulation?

I have been thinking about this project and ahve decided it only requires the solenoid to have "on off" control with a differential.
For future reference do you know of if there is a PID programme for the Micrologix 1000.

If you search in the RA Knowledgebase you may find
other technotes reagrding Micrologix and PID.
