Error contents and cause
Caution; Ladder program writing during RUN is disabled (number of
labels in high-speed processing is beyond the capacity)
 "Local label" is as "labels of local pointer".
With RUN write ON, the number of labels of local pointer in high-
speed processing program has exceeded 256.
Run write is not available with this condition.
Software exceptional interruption (BCD instruction error) has oc-
curred.
With BCD and DBCD instructions, BIN value outside its input range
was attempted to be converted into BCD.
Software exceptional interruption (BIN instruction error) has oc-
curred.
With BIN and DBIN instructions, BCD value outside its input range
was attempted to be converted into BIN.
Software exceptional interruption (Bus error) has occurred.
When the specified device exceeds the range of the device
Software exceptional interruption (Instruction bus error) has oc-
curred.
(1) When the bit selection parameter (#6452 bit6) "branch destina-
tion label check valid" is set to "0", jumped to an undefined label.
(2) Sequence program in execution is broken.
Software exceptional interruption (Instruction format error) has oc-
curred.
Software exceptional interruption (Instruction bus error) has oc-
curred.
(1) When the bit selection parameter (#6452 bit6) "branch destina-
tion label check valid" is set to "0", jumped to an undefined label.
(2) Sequence program in execution is broken.
Software exceptional interruption (CALL/RET instruction error) has
occurred.
Software exceptional interruption (ASYNC BUS error) has occurred. Contact Mitsubishi Electric.
The ladder is stopped.
The ladder is stopped and the edited sequence program is not
stored in the built-in ROM. (The contents of temporary memory area
and sequence program in the builtin ROM are mismatched.)
The edited sequence program is not stored in the built-in ROM. (The
contents of temporary memory area and sequence program in the
built-in ROM are mismatched.)
RUN write is not available when the number of labels of local pointer
in high-speed processing program exceeds 256. Edit the high-speed
program to reduce the number of labels of local pointer to less than
256.
(When multi-project is valid, edit the program to reduce the number
of labels of local pointer to less than 256 per project.)
Check the usage of BCD, DBCD instructions existing in the steps oc-
curred.
Check the usage of BIN, DBIN instructions existing in the steps oc-
curred.
(1) Check and correct the device range that the instruction in the step
of which the error occurred accesses.
(2) Contact Mitsubishi Electric.
(1) Set the bit selection parameter (#6452 bit6) "branch destination
label check valid" to "1" and check the branching step to the un-
defined label.
(2) Contact Mitsubishi Electric.

(1) Set the bit selection parameter (#6452 bit6) "branch destination
label check valid" to "1" and check the branching step to the un-
defined label.

Use GX Developer/GX Works2 or the built-in PLC edit function to
perform write to the built-in ROM.
