Hello, For S71200, and if you have only one active heating element to control temperature, you can use "PID Compact" of STEP7 Basic with PWM output (output_PWM).In this case ,PLC tries to map the analog output of PID controller via an digiatal output with pulse width modulation algorithm.More information is available in the attachment or check the following tip: TIPS for PID (FB PID_Compact)Best regardsHamid Hosseini AttachmentPID_COMPACT.pdf (1337 Downloads) |

Hello to all. For a plant laboratory where I have to control 16 zones of heating and the working temperature ranges from 30 ° C to 300 ° C I created (after on the PID has sent me so many times in the PLC stop) an FC in order to control the temperature. The system works by 10 months the temperature change with the right settings and 1 ° C up to 300 ° C and not to ever give you problems. gemini67 AttachmentTEMP_CONTROL.zip (1287 Downloads) |

@Jav Pinz: @AutoGen_924782: As alternative - attached is a PDF print-out made from TIA Portal V11 for you to study. Ihave not studied the code myself and have no opinion on how it was coded. w AttachmentTEMP_CONTROL.pdf (693 Downloads) |
