Circuit error [M8066(D8066)]
6619
Stops
operation
Invalid instruction is used in FOR-NEXT loop:
STL, RET, MC, MCR, I (interrupt pointer) or IRET.
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.
6620
FOR-NEXT instruction nesting level exceeded
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)]

No error

operation
•
No jump destination (pointer) for CJ or CALL
instruction
•
Label is undefined or out of P0 to P4095 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:
"T200Z" itself is not an error. But if Z had a value of
400, the timer T600 would attempt to be accessed.
This would cause an operation error since there is
no T600 device available.
6702
CALL instruction nesting level is 6 or more
6703
Interrupt nesting level is 3 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.
6707
File register is accessed without parameter setting
of file register.
6708
FROM/TO instruction error
This error occurs in the execution of operation.
•
Review the program and check the contents of
the operands used in applied instructions.
•
Verify that the specified buffer memories exist in
the counterpart equipment.
•
Verify that extension cables are correctly
connected.
6709
Other (e.g. improper branching)
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:
"T200Z" itself is not an error. But if Z had a value of
400, the timer T600 would attempt to be accessed.
This would cause an operation error since there is
no T600 device available.
