2.2.7.22 Registers 0651 to 0764, 0781 to 0782, 0787 to 0788, and 16013 to 16018: PQ
Measured Values, Maximum 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
