0x03 | Faulty Quantity The data count in read or write operations is outside the allowed range (1 to the maximum, as defined per model).
0x04 | Data Type Error Not supported by the defined mode or data type. Not supported by the protocol ID or device code.
0x81 | Protocol ID Setting Error When running a vendor specific command, the protocol ID did not match the I/O.
0x82 | Data Length Setting Error When running a vendor specific command, the data length setting for the vendor special area does not match the I/O.
0x83 | Vendor Special Area Error When running a vendor specific command, a vendor special error occurred in the vendor special area.

- If the error code is 0x83, and the vendor special error code is 0x01, it is displayed 83,01.

Vendor special error code

Error Code | Description
0x01 | Azbil protocol ID setting error The specified Azbil protocol ID is not supported by the I/O.

- If the error code is 0x83, and the vendor special error code is 0x81, it is displayed together with the Modbus error.

Example:

Error code = 0x83, vendor special error code = 0x81, and Modbus error code = 0x01, it is displayed 83,81,01.
