2.2.7.21 Registers 0531 to 0644, 0779 to 0780, 0785 to 0786, and 16007 to 16012: PQ
Measured Values, Minimum 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.).
