Question
Why are the readings different on my sc controller and PLC/SCADA system?
Summary
sc controllers output configuration
Answer
The scaling or span must match between the sc controller and the PLC to match readings. For the sc200, go to System Setup > sc200 Setup > Output Setup > Activation. Make sure that the set low value and set high value match between the sc controller and the PLC/SCADA system.
