Port specified by inverter communication instruction is
already used in another communication.
1) Input (X) specified by a DSZR, DVIT or ZRN
instruction is already used in another instruction.
2) The interrupt signal device for a DVIT instruction is
outside the allowable setting range.
Pulse output number is already used in a positioning
instruction or pulse output instruction (PLSY, PWM,
etc.).
Number of applied instruction exceeds limit.

Action
Check to make sure the port is not specified by another
instruction.
1) Check to make sure the input (X), as specified by a
DSZR, DVIT or ZRN instruction, is not being used for
the following purposes:
- Input interrupt (including the delay function)
- High-speed counter C235 to C255
- Pulse catch M8170 to M8177
- SPD instruction
2) Check the contents of D8336 for the correct interrupt
signal specification for a DVIT instruction.
Check to make sure the pulse output destination is not
being driven by another positioning instruction.
Verify that the number of times that applied instructions
are used in the program does not exceed the specified
limit.
When the memory cassette is used, check whether it is
mounted correctly.
If the problem persists or if the memory cassette is not
used, something may be malfunctioning inside the PLC.
Consult your local Mitsubishi Electric representative.
Check for the correct attachment of the memory cassette.
The write-protect switch of the memory cassette was set
to ON when data was transferred
to the flash memory. Set the protect switch to OFF.
While data was written in the RUN mode, data was
transferred to (read from or written to) the memory
cassette.
Verify that extension cables are correctly connected.
When the memory cassette is used, check whether it is
mounted correctly.
If the problem persists, consult your local Mitsubishi
Electric representative.
This error occurs in the execution of operation.
• Review the program and check the contents of the
operands used in applied instructions.
• Verify that specified buffer memories exist in the
counterpart equipment.
• Verify that extension cables are correctly connected.
• Check the cable connection between the
programming panel (PP) / programming device and
the PLC.
• Verify that extension cables are correctly connected.
.
Action
This error occurs when an operation is executed or when
the END instruction is executed.
• 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.
