Waow, by setting gain to 1 and offset to 0 did solve it and works now correctly. As I did not set this gain in the PI, it has been set automatically, and seems I have overlooked this one. Can I ask you another question? If I would like to use a 3 way valve with a two direction 220V motor instead of a proportional valve (4 to 20mA), how could we program two digital ouputs one to open the valve and one to close depending on PI controller deviation? Thanks ------------------------------------------------------------------------------------------ |

Do you have an example how to program a 3 point step controller? |

Or try this with two PI controllers.

Here is an example of a 3-point step controller. It has two hysteresis areas. Attachment3-point_step_controller_0BA8.Standard.zip (677 Downloads) |

Please don't upload a PDF file. Upload your LSC program as a ZIP file. |

For the temperature measurement: What hardware do you use? PT100/1000 with the AM2 RTD modul? |
