Q.I am using an AZ Series EtherNet/IP compatible driver. I would like to execute a maintenance command. How do I do this?

Set the parameter ID of the maintenance command you would like to execute to the write parameter ID, and set the WR-REQ bit of the write request to ON.

• *Confirm the AZ Series EtherNet/IP ^TM-compatible driver user manual for the parameter ID of the maintenance command.

This section describes the setting procedure using "write batch NV memory" as an example.

1. Confirm WR-END is turned OFF
2. Write Batch NV Memory Parameter ID: Set 201 as the write parameter ID (For HEX input, set C9h)
3. Turn ON WR-REQ (The 0th bit of the write request)
4. Confirm that the maintenance command is executed and WR-ERR is OFF and WR-END is ON
5. Turn OFF WR-REQ and clear the write parameter ID

[Note]

• For details on maintenance commands, refer to the AZ Series Function Edition.

  • *When viewing the AZ Series Function Edition, refer to the name of the parameter instead of the parameter ID.
• Maintenance commands include non-volatile memory batch processing or P-PRESET, there are processes that manipulate memory.
  Be careful to avoid unnecessary continuous execution.
• Some of the maintenance commands may have different procedures from the above. Refer to the user manual for details.
