Operation error [M8067(D8067)]
0000 No error
• There is no jump destination for CJ or CALL
instruction.
• The label is undefined or outside the range from
6701 P0 to P4095 due to indexing.
• The label P63 is executed in the CALL instruction.
P63 cannot be used in the CALL instruction
because it offers jump to the END instruction.
6702 The nesting level of CALL instruction is 6 or more.
6703 The nesting level of interrupt is 3 or more.
The nesting level of FOR-NEXT instructions is 6 or
6704
more.
An unavailable device is used as an operand in an
6705
instruction.
The device number or data value of an operand in an
6706
instruction is outside the allowable range.
A file register is accessed without its parameter
6707
setting.

Action
This error occurs while the PLC is executing an operation.
Review the program and check the contents of operands used in
instructions.
Even if the syntax or circuit design is correct, an operation error may
occur for the following reasons, for example.
Example:
"T500Z" itself is not an error. However, if Z is "100", "T500Z" means
"T600" which causes a device number error.
This error occurs while the PLC is executing an operation.
• Review the program and check the contents of operands used in
instructions.
• Confirm that the specified buffer memory exists in the counterpart
equipment.
• Confirm that extension cables are connected correctly.
This error occurs while the PLC is executing an operation.
Review the program and check the contents of operands used in
instructions.
Even if the syntax or circuit design is correct, an operation error may
occur for the following reason, for example.
Example:
"T500Z" itself is not an error. However, if Z is "100", "T500Z" means
"T600" which causes a device number error.
This error occurs when a same device is used in both the source and
the destination in a shift instruction, etc.
<The PLC stops PID operation.>
This data error occurs in the control parameter set value or during
PID instruction.
Check the contents of parameters.
<The PLC continues auto tuning.>
The PLC continues the operation in the condition "Sampling time (Ts)
= Cyclic time (Scan time)".
