0020 A minor error bit is set at the end of the
scan. Refer to S:5 minor error bits.
X • ••••
0021 Remote power failure of an expansion
I/O chassis occurred.
X • ••••
TIP
A modular system that encounters an over-voltage or over-current
condition in any of its power supplies can produce any of the I/O error
codes listed on pages -32 and -34 (instead of code 0021). The
over-voltage or over-current condition is indicated by the power supply
LED being off.
ATTENTION
Fixed and FRN 1 to 4 SLC 5/01 processors - If the remote power failure
occurred while the processor was in the REM Run mode, error 0021
will cause the major error halted bit (S:1/13) to be cleared at the next
powerup of the local chassis.
SLC 5/02 processors and above and FRN 5 SLC 5/01 processors -
Power to the local chassis does not need to be cycled to resume the
REM Run mode. Once the remote chassis is re-powered, the CPU will
restart the system.
0022 The user watchdog scan time has been
exceeded.
X • ••••
0023 Invalid or non-existent STI interrupt file. X ••••
0024 Invalid STI interrupt interval (greater
than 2559 ms or negative).
X ••••
0025 Excessive stack depth/JSR calls for STI
routine.
X ••••
0026 Excessive stack depth/JSR calls for I/O
interrupt routine.
X ••••
0027 Excessive stack depth/JSR calls for
user fault routine.
X ••••
0028 Invalid or non-existent “startup
protection” fault routine file value.
X ••••
0029 Indexed address reference outside of
entire data file space (range of B3:0
through the last file).
X•
ATTENTION
The SLC 5/02 processor uses an index value of zero for the faulted
instruction following error recovery.
002A Indexed address reference is beyond
specific referenced data file.
