You have to build the required function your self. But what do you meant by "several setpoints?" |

Hi, For your time switch the best example you can get from: www.s7-200.net Her you can download free of charge Libraries from LOGO! functions translated to S7-200 code. I'm not a HVAC specialist but as I understand your heating systems: 1. The indoor heating does only switch on if the outside temp. is < then 17° cel. 2. The indoor temp you can controll via S7-200 PID control function. Use the Wizard in Micro/WIN for configuration. 3. A application like this normaly also requires a scalling funktion. Here is an example: To import it to Micro/WIN see the online help. I hope this helps. Regards Helmut AttachmentScaling.zip (235 Downloads) |
