Error Flag
Name
These words contain the 8-digit
binary program address of the
instruction where program execution
was stopped due to a program error.
(A294 contains the task number of
the task where program execution
was stopped.)
When an error occurs, the Error Log
Pointer is incremented by 1 to indi-
cate the location where the next
error record will be recorded as an
offset from the beginning of the Error
Log Area (A100 to A199).
The Error Log Pointer can be
cleared to 00 by turning A50014 (the
Error Log Reset Bit) from OFF to
ON.
When the Error Log Pointer has
reached 14 (20 decimal), the next
record is stored in A195 to A199
when the next error occurs.
This word contains the current EM
bank number in 4-digit hexadecimal.
The current bank number can be
changed with the EMBC(281)
instruction.
These flags are ON while the corre-
sponding CPU Bus Unit is initializing
after its CPU Bus Unit Restart Bit
(A50100 to A50115) is turned from
OFF to ON or the power is turned
ON.
Bits 00 to 15 correspond to unit
numbers 0 to 15.
Use these flags in the program to
prevent the CPU Bus Unit’s refresh
data from being used while the Unit
is initializing. IORF(097) cannot be
executed while an CPU Bus Unit is
initializing.
These bits are turned OFF automati-
cally when initialization is com-
pleted.
ON: An inconsistency exists
between the program or memory of
the active and standby CPU Units in
Duplex Mode. (Refer to A317 and
A804 for details.)
ON: An error occurred on the sync
transfer bus in the duplex mode.
ON: An error occurred in the Power
Supply Unit or power supply system
on a duplex CPU Rack, Expansion
Rack, or Long-distance Expansion
Rack. Error details are stored in
A319 and A320.
ON: One of the duplex Communica-
tions Units has failed. (Refer to A434
to A437 for details.)
