gram error
information A29512: Task error
A task error has occurred.
The following conditions will
generate a task error.
1) There is not an executa-
ble cyclic task.
2) There is not a program
allocated to the task. Check
A294 for the number of the
task missing a program.
3) The task specified in a
TKON(820), TKOF(821), or
MSKS(690) instruction does
not exist.
A29510: Illegal access error
An illegal access error has
occurred and the PC Setup
has been set to stop opera-
tion for an instruction error.
The following are illegal
access errors:
1. Reading/writing a param-
eter area.
2. Writing memory that is not
installed.
3. Writing an EM bank that is
EM file memory.
4. Writing to a read-only
area.
5. Indirect D/EM address
that is not in BCD when BCD
mode is specified.
A29509: Indirect D/EM BCD
error
An indirect D/EM BCD error
has occurred and the PC
Setup has been set to stop
operation for an instruction
error.
A29508: Instruction error
An instruction processing
error has occurred and the
PC Setup has been set to
stop operation for an instruc-
tion error.
A29514: Illegal instruction
error
The program contains an
instruction that cannot be
executed.
Probable cause
After writing any changes to the pro-
gram, switch to PROGRAM mode and
then return to MONITOR mode to con-
tinue editing the program.
Check the startup cyclic task attributes.
Check the execution status of each task
as controlled by TKON(820) and
TKOF(821).
Check the relationship between task
numbers and the program.
Make sure that all of the task numbers
specified in TKON(820), TKOF(821), and
MSKS(690) instructions have corre-
sponding tasks.
Use MSKS(690) to mask any I/O or
scheduled interrupt tasks that are not
being used and that do not have pro-
grams set for them.
Find the program address where the
error occurred (A298/A299) and correct
the instruction.
Alternatively, set the PC Setup to con-
tinue operation for an instruction error.
Find the program address where the
error occurred (A298/A299) and correct
the indirect addressing or change to
binary mode.
Alternatively, set the PC Setup to con-
tinue operation for an instruction error.
Find the program address where the
error occurred (A298/A299) and correct
the instruction.
Alternatively, set the PC Setup to con-
tinue operation for an instruction error.
Re-transfer the program to the CPU Unit.
