I am tring to bring the temperature control of some electric heaters into a AD Prod 2000 PLC and need some help. The current temperature controlers use a PID loop to keep temperature constant. They have a discrete output firing a SSR.
Is there a instruction in the PLC to do this? Both the PID and Ramp instructions use a analog output, or will I have to build some back end logic off of the PID.
