Circuit error [M8066(D8066)]
0000 ⎯ No error
6610
Stops
operation
LD, LDI is continuously used 9 times or more.
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.
6611
More ANB/ORB instructions than LD/LDI
instructions
6612
Less ANB/ORB instructions than LD/LDI
instructions
6613 MPS is continuously used 12 times or more.
6614 No MPS instruction
6615 No MPP instruction
6616
No coil between MPS, MRD and MPP, or incorrect
combination
6617
Instruction below is not connected to bus line:
STL, RET, MCR, P, I, DI, EI, FOR, NEXT, SRET,
IRET, FEND or END
6618
STL, MC or MCR can be used only in main
program, but it is used elsewhere (e.g. in interrupt
routine or subroutine).
6619
Invalid instruction is used in FOR-NEXT loop:
STL, RET, MC, MCR, I (interrupt pointer) or IRET.
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)]
0000 No error
6701
Continues
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, or check the contents of the
operands used in the 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.
Error codes in shaded columns are added in FX
3U PLCs.
