Figure 6.3 LAD5 - PCP Read Subroutine (Continued)
N22:12 = Index (the parameter number or fault/event queue item to be read)
N22:1 determines what area is to be read:
0 = PowerFlex 70 (Host) parameter (N22:2 + 12288 decimal (3000h) = mapped parameter address)
1 = 20-COMM-I parameter (N22:2 + 12213 decimal (2FB5h) = mapped parameter address)
2 = PowerFlex 70 (Host) Fault queue (N22:2 + 12280 decimal (2FF8h) = mapped fault item)
3 = 20-COMM-I Event Queue (N22:2 + 12205 decimal (2FADh) = mapped event item)
