Learning Objective:
In module B3, the reader learns the following: how a PID controller is integrated into a STEP7
program, how it is wired to analog process variables, and how it is started. The following steps are
discussed:
• Program example for a two position controller
• Calling a PID controller in a STEP 7 program
• Wiring the PID controller to analog process variables
• Setting the controller parameters at the PID controller
Prerequisites:
To successfully work through Module B3, the following knowledge is assumed:
• Knowledge in handling Windows
• Fundamentals of PLC programming with STEP 7 (for example, Module A3 – 'Startup’
PLC Programming with STEP 7)
• Analog Value Processing with STEP 7 (for example, Module B2 – Analog Value Processing)
