14.6 Judgment by Error Codes and Representation of Error Codes
Circuit error [M8066 (D8066)]
6620
Stops
operation
FOR-NEXT instruction nesting level exceeded
This error occurs when a combination of instructions is
incorrect in the entire circuit block or when the relationship
between a pair of instructions is incorrect.
Modify the instructions in the program mode so that their
mutual relationship becomes correct.
6621 Numbers of FOR and NEXT instructions do not match.
6622 No NEXT instruction
6623 No MC instruction
6624 No MCR instruction
6625 STL instruction is continuously used 9 times or more.
6626
Invalid instruction is programmed within STL-RET loop:
MC, MCR, I (interrupt pointer), SRET or IRET.
6627 No STL instruction
6628
Invalid instruction is used in main program:
I (interrupt pointer), SRET or IRET
6629 No P or I (interrupt pointer)
6630
No SRET or IRET instruction
STL-RET or MC-MCR instructions in subroutine
6631 SRET programmed in invalid location
6632 FEND programmed in invalid location
Operation error [M8067 (D8067)]
0000 - No error
6701
Continues
operation
• No jump destination (pointer) for CJ or CALL instruction
• Label is undefined or out of P0 to P255 due to indexing.
• Label P63 is executed in CALL instruction; cannot be used
in CALL instruction as P63 is for jumping to END
instruction.
This error occurs in the execution of operation. Review the
program and check the contents of the operands used in
applied instructions.
Even if the syntax or circuit design is correct, an operation
error may still occur.
For example:
"T100Z" itself is not an error. But if Z had a value of 100, the
timer T200 would attempt to be accessed. This would cause
an operation error since there is no T200 device available.
6702 CALL instruction nesting level is 6 or more
6704 FOR-NEXT instruction nesting level is 6 or more.
6705 Operand of applied instruction is inapplicable device.
6706
Device number range or data value for operand of applied
instruction exceeds limit.
6709 Other (e.g. improper branching)
6710 Mismatch among parameters
This error occurs when the same device is used within the
source and destination in a shift instruction, etc.
6730 Incorrect sampling time (T
S) (TS 0)
<PID instruction is stopped.>
This error occurs in the parameter setting value or operation
data executing PID instruction.
Check the contents of the parameters.
6732

6733 Incompatible proportional gain (K
