Powermeasurement by modbuscoupler

CODESYS

Hi, I try to read the data from a 750-494 card via a modbuscoupler in Codesys. But I’m stuck in the communication setup. Anyone who has experience in this matter?

Hi, you can find an example of this in the sample projects at the link below. The README file identifies which project demonstrates the coupler configuration used in the WAGOAppPowerMeasurement library examples.

WAGO just posted a YouTube video on this. They also cover using the built in Modbus Configurator with a PMM module.

Great Timing :slight_smile:
