Creating PID control in S7-200 for steam control

I have a problem with creating PID control in S7-200 for steam control.

Kindly assist with a sample program.

Hello Kubai;

First, start by examining the following general information for S7-200 PIDs:

https://support.industry.siemens.com/cs/ww/en/view/459438

Then follow the Tips and Tricks link to access Tips 53 and 54, as suggested to get an understanding of PIDs in the S7-200 environment.

The Tips and Tricks are Micro-Automations applications, with documentation and sample code, designed to help engineers and programmers using S7-200 controllers develop their own expertise with specific automation problems. Tip 53 shows how to use the MicroWin PID Wizard to simplify the configuration of the PID instruction in the S7-200, Tip 54 explains how to use the PID instructions in your program. Both of these Tips are found in the Regulatory Control section of theTtips; you should also look in the Positioning section, where you will find examples of closed-loop and open-loop controls. 

Use the Tips and Tricks as a basis to implement your loop control: start by designing your loop, drawing all control elements and how you want them to interact. Then modify the  suggested Tips to adapt them to your situation.

If you need more help here later, please give us more information on the loop you are trying to control.

Hope this helps,
