    The measured values are read out in various ways. For one, all measured values are filed in registers that can be read out via Modbus. Additionally, they can be sent to a PC via the Config interface. This requires the WAGO USB Communication Cable (750-923). The measured values are then configured and vi- sualized on the PC with the Interface Configuration Software.
