Operation error [M8067 (D8067)]
0000 - No error
• No jump destination (pointer) for CJ or CALL instruction
• Label is undefined or out of P0 to P255 due to indexing.
6701 • Label P63 is executed in CALL instruction; cannot be used
in CALL instruction as P63 is for jumping to END
instruction.
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.
Device number range or data value for operand of applied
6706
instruction exceeds limit.

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.
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.
This error occurs when the same device is used within the
source and destination in a shift instruction, etc.
<PID instruction is stopped.>
This error occurs in the parameter setting value or operation
data executing PID instruction.
Check the contents of the parameters.
