Chapter 7 Drive and Loop Control

Logix Analog Control

The RSLogix 5000 instruction set includes a PID block that executes control

over a process variable. The PID calculations are performed on an analog

signal coming from a standard analog input module. The PID output is

transferred to the corresponding control variable via a standard analog output

module. The PID calculations are performed by the controller so no dedicated

hardware module is required.

A PID Tag is defined in the tag database and it automatically generates all the

required PID elements.

In the FBD language, an enhanced PIDE block is also available.
