Page Index:
• If IND = 1 (system environment variables (sev) area), the PP values specify different blocks of sev's:
PP = 0: sev_I, block I
PP = 1: sev_II, block II (alarm history)
PP = 2: sev_III, block III
(For details, refer to page
• If IND is other than 1, set PP to 0.
Parameter Index:
Specifies the area from which Parameter Number (PNU) is being accessed.
(For details, refer to page
IND = 0: real-time monitor area
IND = 1: system environment variable (sev) area (3 blocks)
IND = 2: normal parameter area
IND = 3: Pr.900 to calibration parameter (frequency) area
IND = 4: Pr.900 to calibration parameter (%) area
