Words A012 and A013 contain, in BCD format, the time at which power was in-
terrupted, as shown in the following table. The power interruption time is up-
dated every time the power is interrupted.
Word Bits
A012 00 to 07 Seconds
08 to 15 Minutes
A013 00 to 07 Hours
08 to 15 Day of month 01 to 31 (adjusted by month and for leap year)
Note During duplex operation, the power interruption time in the active CPU Unit will
not agree with the power interruption time in the standby CPU Unit.
Word A014 contains the number of times that power has been interrupted since
the PC was first turned on. The number is in 4-digit BCD, and can be reset by
writing #0000 to word A014.
Note During duplex operation, the number of power interruptions in the active CPU
Unit will not agree with the number in the standby CPU Unit.
Words A015 and A017 contain control bits that disable I/O servicing to certain
Units and periodic refreshing. Turn these bits ON and OFF in the program. The
service disable bits are automatically turned OFF when power is turned on or PC
operation is stopped.
Bits A01500 through A01515 can be turned ON to stop service to CPU Bus Units
numbered #0 through #15, respectively. Turn the appropriate bit OFF again to
resume service to the CPU Bus Unit.
Note During duplex operation, the status of the CPU Service Disable Bits in the active
CPU Unit will not agree with the same bits in the standby CPU Unit.
Bit A01703 can be turned ON to stop Host Link System servicing. Turn OFF
again to resume service to the Host Link System.
Bit A01704 can be turned ON to stop service to Programming Devices. Turn
OFF again to resume service to Programming Devices.
Bit A01705 can be turned ON to stop SYSMAC BUS refreshing. Turn OFF again
to resume SYSMAC BUS refreshing.
When the MESSAGE instruction (MSG(195)) is executed, the bit in A099 corre-
sponding to the message number is turned ON. Bits 00 through 07 correspond
to message numbers 0 through 7, respectively.
Words A100 through A199 contain up to 20 records that show the nature, time,
and date of errors that have occurred in the PC. The Error Log Area will store
system-generated or FAL(006)/FALS(007)-generated error codes. Refer to
Section 6 Troubleshooting in the CVM1D PCs Installation Guide for details on
error codes.
