Just getting going with Temco hardware. We’re trying to use the T3-TB as a field data interface with temp, humidity, occupancy, etc. Then, the data will be imported into the main PLC over Modbus TCP.
In bench testing, I hooked up two PT1000 to inputs 1 and 2. The software found the T3-TB and the I found the setup data for the probes in the drop down menu (Range PT 1K -200 to 300) and (Sensor PT 1K).
However, I was a bit surprised that I had to add a calibration number to get a temperature even close to reality. Even then, the values roll up and down over a significant range. For what its worth, the real world range only needs to be -40 to +40 C.
Is there something I’m missing? Do I need pullup/pulldown? I just expected to find a built-in drop-down menu item related to the specific probes.
