In the previous video, we learned:
How each term of the PID control equation affects a process controller in automatic mode, and,
How the process reaction curve values of “Process Gain”, “Dead time”, and “Time Constant” can be used to determine the tuning parameters for a PID controller.
In this video we will learn:
How to use the Ziegler-Nichols method to calculate the values of P, I and D tuning parameters, and,
How to tune a PID controller using two different methods.
In this video, I show you:
- How to create an Organization Block (OB) that executes every 1 second.
- How to create a PID control block in an S7-1500 series PLC.
In this video, we will demonstrate:
- How to develop a suitable process variable simulation that will be used to test the PID algorithm in the PLC.
In this video:
- I will complete the ladder logic for implementing PID control in a Siemens S7-1516 controller.
- I will download the program to the PLC and prepare to test the simulated process and PID loop.
