Control of the instruction can be switched between Program and Operator modes.It uses the velocity form of the PID algorithm. This is especially useful for adaptive gains or multiloop selection.The PIDE (Enhanced PID) is an Allen Bradley Logix5000 family (ControlLogix, CompactLogix, FlexLogix, SoftLogix) function block that improves on the standard PID found in all their controllers. First impressions of this function block are quite intimidating. If you try to dive into it head first you may just end up banging your head against a wall. Many will be quite happy to stick with the tried and true PID instruction but to compete with the more advanced process control applications the PIDE boasts the following.
