Bits A40500 through A40515 correspond to CPU Bus Units #0 through #15, re-
spectively. When a CPU Bus Error occurs, the bit corresponding to the unit num-
ber of the CPU Bus Unit involved is turned ON.
Bit A40113 is turned ON when two Racks are assigned the same rack number,
two CPU Bus Units are assigned the same unit number, or the same words are
allocated to more than one Rack or Unit in the PC Setup. The duplicate Expan-
sion I/O Rack number is written to word A409, and the duplicate CPU Bus Unit
number is written to word A410.
Bits A40900 through A40907 correspond to Racks #0 through #7, respectively.
When two Racks have the same rack number, the bits corresponding to the rack
numbers involved are turned ON. Bit A40915 is also turned ON to indicate that
the same words are allocated to more than one Rack or Unit in the PC Setup.
Bits A41000 through A41015 correspond to CPU Bus Units #0 through #15, re-
spectively. When two CPU Bus Units have the same unit number, the bits corre-
sponding to the unit numbers of the CPU Bus Units involved are turned ON.
Bit A40114 is turned ON when an error occurs during the transmission of data
between the CPU and I/O Units through the I/O bus, or a terminator is not
installed correctly. The rack/slot number of the Unit involved is written to word
A404.
Bits A40400 through A40407 contain the slot number, in BCD, of the I/O Unit
where the error occurred. If the error did not occur with an I/O Unit, then these
bits contain #0F. Bits A40408 through A40415 contain the rack number, in BCD,
of the Rack where the error occurred.
If the error occurred because of a terminator setting, word A404 will contain
#0E0F for line 0 (IOC right connector), or #0F0F for line 1 (IOC left connector).
Bit A40115 is turned ON when an error occurs in memory. The memory area in-
volved is written to word A403.
Bit A40201 is turned ON when an error is detected in the duplex bus error check.
Bit A40202 is turned ON when power is momentarily interrupted if a momentary
power interruption is set as an error in the PC Setup (see "Error on power off" in
the PC Setup). The time and date of the most recent power interruption is written
to words A012 and A013, and the number of power interruptions is written to
word A014.
Bit A40203 is turned ON when the CPU Bus Units actually installed differ from
the Units registered in the I/O table. The unit number of the CPU Bus Unit in-
volved is written to word A427.
Bits A42700 through A42715 correspond to CPU Bus Units #0 through #15, re-
spectively. When a error occurs, the bit corresponding to the unit number of the
CPU Bus Unit involved is turned ON.
Bit A40204 is turned ON if the voltage of the CPU or Memory Card battery drops.
If the problem has occurred with the Memory Card battery, bit A42614 will be
