A.5 Register “Instantaneous Value” of the selected measured quantity
Data block of the package consists of combination of bytes. The block structuire:
Idx InsMV InsPSS UniqSec
Designation
Idx – index of register = 0×09, 1 byte, data type BYTE(1);
InsMV – measurement result of selected measured quantity, 4 bytes, data type Single (25)
(see description of the register “Selection of the measured quantity” in the table A.1), calculated using
data for the UniqSec-th second;
InsPSS – number of pulses acquired during UniqSec-th second, 4 bytes, data type Single (25);
UniqSec – unique identifier (changes every second), 4 bytes, data type DWORD (11).
Examples of packages are presented in the Table A.4.
