@CodeShepherdthank you for your quick answer. In your example you set the command value to (00,00,128,00,00,01,00,01,00,01,00,01). I don´t understand exactly how you get that 128. As you can see in the picture I did my parameterization along the documentation for the S20-AI-4-RTD. With the PT 1000 2-wire temperature sensor my result is (01,00,11,00,00,00,00,00). I also tried (00,00,128,01,00,01,00,11,00,00,00,00,00) and some other variants but with no success. I didn´t understand how to connect the documentation "Writing to PDI objects with PDI Write Tunnel” with the documentaion "S20-AI-4-RTD - Application objects" Can you help me out please?
