2.2.7.20 Registers 0401 to 0514, 0777 to 0778, 0783 to 0784, and 16001 to 16006: PQ
Measured Values, Average Values (Read Only)
These registers are write-protected. A write attempt will be rejected with exception code 02
(ILLEGAL_DATA_ADDRESS).
The data are calculated within the parameterized time (for example 30 s, 1 min etc.).
Data type: Measured value
