"ACT" or "ST-BY" is output in PIR field in the following conditions. However, this parameter does
Note 4:
not output connection status of BUS cables between PIRs and between PIR and TSWR.
• At least one actual PIR is mounted by assignment of PIR mounting status (ASYDL, System 1, Index 512-
513) and Unit status (ASYDL, System 1, Index 1026-1027).
• BUS cable is connected between EXB card and PIR0 or TSWR
The followings are details of PIR output data.
Note 5:
• "ACT" or "ST-BY" output for PIR will be the same as that of CPU.
• When BUS cable is not connected between EXB card and PIR or TSWR, "Disconnect" will be output.
• When only virtual PIR is mounted, "Not Mount" will be output.
System 0: Status of each parameter in System 0 side
• 0=Not Mount
• 1=ACT
• 2=ST-BY
• 3=MB
• 4=Disconnect
System 1: Status of each parameter in System 1 side
• 0=Not Mount
• 1=ACT
• 2=ST-BY
• 3=MB
• 4=Disconnect
This data is output in the case of PIR only (Available since FP85-104 S1E).
Note 6:
When EXB card of STBY CPU and BUS cable in PIR are not connected ("Disconnect" will be output)
Note 7:
and trying to execute CPU mode changing, the following message will be output in a pop-up menu:
"STBY PIR is improper. Execute mode changing?". When "Yes" is selected, the mode changing is ex-
ecuted. When "No" is selected, it is not executed (Available since FP85-104 S1E).
When EXB card of ACT CPU and BUS cable in PIR are connected correctly ("ACT" will be output)
Note 8:
and EXB card of STBY CPU and BUS cable in PIR are not connected ("Disconnect" will be output),
if CPU mode changing is executed, the mode will be returned to the mode before the execution. It is
held by new ACT side faulty recovery to check the irregular between EXB card=PIR 0 and the discon-
nection of BUS card in PIR. This action is done while the output message of the mode change executing
is displayed ("Changing" will be output). Therefore, at the time of CPU mode is output again, dis-
played mode is not changed yet (Available since FP85-104 S1E).
