Program for details.
error
The address at which the pro-
informa-
gram stopped will be stored in
tion
A298 and A299. The task
where the program stopped
will be stored in A294.
A29511: No END error
A29512: Task error
A task error has occurred. The
following conditions will gener-
ate a task error.
1. There isn't an executable
cyclic task.
2. There isn't a program allo-
cated 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
doesn't exist.
A29510: Illegal access error
An illegal access error has
occurred and the PLC Setup
has been set to stop operation
for an instruction error. The fol-
lowing are illegal access
errors:
1. Reading/writing a parame-
ter 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 DM/EM address
that is not in BCD when
BCD mode is specified.
A29509: Indirect DM/EM BCD
error
An indirect DM/EM BCD error
has occurred and the PLC
Setup has been set to stop
operation for an instruction
error.
A29508: Instruction error
An instruction processing error
has occurred and the PLC
Setup has been set to stop
operation for an instruction
error.
A29513: Differentiation over-
flow error
Too many differentiated
instructions have been
inserted or deleted during
online editing.

Possible remedy
If the error has occurred in both the active
and standby CPU Units, use the information
in A294, A298, and A299 to find the location
and cause of the error, check the program,
and correct the error. Then, clear the error.
If the error occurred in only one of the CPU
Units, use one of the following methods.
• Toggle the USE/NO USE switch for the
CPU Unit with the error to NO USE and
back to USE and then press the initializa-
tion button.
• If the automatic recovery setting has been
enabled in the PLC Setup, use the auto-
matic recovery function to restart.
• If operation still cannot be recovered,
replace the CPU Unit.
If the error has occurred in both the active
and standby CPU Units, place END(001) at
the end of the task indicated in A294.
If the error has occurred in both the active
and standby CPU Units, check the startup
cyclic task attributes.
Check the execution status of each task as
controlled by TKON(820) and TKOF(821).
Make sure that all of the task numbers spec-
ified in TKON(820), TKOF(821), and
MSKS(690) instructions have corresponding
tasks.
If the error has occurred in both the active
and standby CPU Units, find the program
address where the error occurred
(A298/A299) and correct the instruction.
If the error has occurred in both the active
and standby CPU Units, find the program
address where the error occurred
(A298/A299) and correct the indirect
addressing or change to binary mode.
If the error has occurred in both the active
and standby CPU Units, find the program
address where the error occurred
(A298/A299) and correct the instruction.
Alternatively, set the PLC Setup to continue
operation for an instruction error.
If the error has occurred in both the active
and standby CPU Units, write any changes
to the program, switch to PROGRAM mode
and then return to MONITOR mode to con-
tinue editing the program.
