PID Temperature Control

Closed-loop control with S7 CPUs

Overview

Description

In addition to the universal PID Control function blocks, STEP 7 offers two control blocks that are specifically for the closed-loop control of simple temperature loops (e.g. heater or cooler controls). This includes parameterization software, a sample project and an electronic manual.

The parameterization software provides a wizard for self-optimization as well as a special commissioning screen, and can be directly started from the SIMATIC Manager.

Apart from the functions described for PID Control, the function block for temperature control features integrated online self-optimization, which is possible without a PG/PC.
A pulse shaper is also integrated for implementing pulse controllers. In contrast to the solution using PID Control, there is no need to connect control blocks – it is parameterized rather than programmed.
An additional function block is used to implement step controllers.
