Contents of error
No error
• 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.
CALL instruction nesting level is 6 or more
Interrupt nesting level is 3 or more
FOR-NEXT instruction nesting level is 6 or
more.
Operand of applied instruction is inapplicable device.
Device number range or data value for operand of
applied instruction exceeds limit.
File register is accessed without parameter setting of file
register.

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:
"T500Z" itself is not an error. But if Z had a value of 100,
the timer T600 would be attempted to be accessed. This
would cause an operation error since there is no T600
device available.
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.

This error occurs when the same device is used within
the source and destination in a shift instruction, etc.
