Invalid Target Table

What does MBX_CMD_INVALID_ARG mean?

This error indicates that an invalid target table has been specified for the MBX_GETUSERFRIENLYNAME command. The system expects a specific target table value, such as '2' for WAGO_DEVICE (slots 1-7) or '1' for EXTERNAL_DEVICE (slots 8-12). An incorrect value for the target table prevents the command from identifying the correct device type, leading to command failure.

• The target table value in MBX_TARGET_TABLE_AND_INDEX (Bits 4-7) is not a valid selection.
• The target table value is not set to '2' for WAGO_DEVICE or '1' for EXTERNAL_DEVICE.

Click steps to track your progress.

1. 1

   Review the MBX_TARGET_TABLE_AND_INDEX parameter (Bits 4-7) used with the MBX_GETUSERFRIENLYNAME command.

2. 2

   Verify that the target table value is set to '2' for WAGO_DEVICE (slots 1-7) or '1' for EXTERNAL_DEVICE (slots 8-12).

3. 3

   Correct the target table parameter to the appropriate value for the intended device type.
