Hi, I am not an expert of solar thermal heating systems - but if you want to discuss your LOGO!-program and/or find out "is ther a better solution possible?", then let as know your LOGO!-program andthe details what you want to do with a LOGO!program (inputs, funktions, displayed values and outputs....). The best is, you tell as your hole projekt, because a disussion about only a part of it sometimes has not the best solution for the complete program... Best regards Betel |

Hi!! ¿ can you post a sample program of your process ? ¿ what are you using as Process variable, and Setpoint ?? i imagine that Process Value is watertemperature at the output of the heater... you can use diferent PI functions for diferent parts of the curve, this example does nothing but demonstrate the use of 3 PI functions with one output Attachmentdiferent PI.zip (458 Downloads) |

Hi Rosa, thanks for the example. Using multiplexer to drive different PI regulator is a good idea !! Best regards Solar Element |
