of the device, read out with DIGSI via the operator interface or transmitted to a control center via port B.
2.18.8.1 Description
Metered Values for Active and Reactive Energy
Metered values of the real power W
hours primary or in kVARh, MVARh or GVARh primary, separately according to the input (+) and output (–), or
capacitive and inductive. The measured-value resolution can be configured. The signs of the measured values
appear as configured in address 1108 P,Q sign (see Section „Display of Measured Values").
