Hi everyone.
I'm trying to read values from a Loadcell with a 2080-TC card.
I know the 2080-TC is a thermocouple card but it reads millivolts that is the signal I need.
I use the TC as type K and with the Type K Thermocouple Reference Table and the formula: Connected Components Workbench software Data Count = (Temp (°C) + 270.0)*10 I know the counts what I need to read in the Input (2700 for 0 mV and 7550 for 20 mV).
The system is like a big pulley, when the load is stable the PLC read a steady value but when the pulley starts moving the value at the input populates from a very low to a very high value constantly.
Does anyone has an idea what would be happening?
As an addition, I'm doing the same with a siemens PLC 1214 with AI1 x TC (6ES7 231-5QA30-0XB0) and it works very well.
As an addition, I used an 0-20 mV calibrator to check the channel and with the calibrator I read 2700 counts with 0 mV and 7750 counts with 20 mV).
