Edelkin77 Posted March 3, 2011 Report Share Posted March 3, 2011 I have a vision 230 with a V200-18-E3XB snap in module. I have changed the jumpers on the analog I/O for RTD operation. I have set up the analog inputs in hardware configuration to PT100 alpha .0385 and set in degrees C mode and have wired the RTD's to the channels. There are only two wires on the RTD's so I have jumpered the positive terminal to CM on all of them. I set up a numeric display box for each and they read 5440 or so and decrease when i warm them. This seems like it is displaying a resistance instead of temperature. What am i missing? I also have a type K thermocouple on the fourth input and it is reading as expected.
