Hi all,
This is my first time programming an analogue input. I understand how the SCP instruction works, and have set the channel to 4-20mA. Using a meter that gives 4-20mA, when I increase the mA, the PLC maxed out at around 17.12mA.
External Dip switches are set to ON (current), what am I missing to get to the full 20 mA without the PLC hitting 32767. See picture, Input is on I:1.0.
