Hi, first, the LOGO! has NO PID-controler block - only PI-controller blocks! Perhaps you can find opinions about your question under: "mixing valve", sheed from Solar Element (only P-property possible to build a 3-point-strpper-controler with 2 relais outputs!) My one works without PI-controler. Best regards Betel |

Hi Jan, your post is older - but now i can give you information about newer solutions: a) I have published an analog PID-controller as circuit under the link "PID-Controller" (circuit) for a LOGO!-0BA6
b) I have publised a 3-point-step-controller with P behaviour at the german forum part under the link c) I have publised a 3-point-step-controller with PD behaviour at the german forum part under the link Konzept für 3-Punkt-Schritt_Regler mit PD-Verhalten (Teil_2) This one can quickly reduced to P behaviour (cleas the two last pages an d add some blocks from a sepatate circuit). That is better as to use b) because it contains newer parts to filter the analog input values. Best regards Betel |
