Index Out of Range

What does MBX_CMD_OUT_OF_RANGE mean?

This error occurs when an invalid table index is selected for the MBX_GETUSERFRIENLYNAME command. Specifically, for 750-644 I/O modules, an index greater than 6 is invalid, and for Bluetooth SPP devices, an index greater than 5 is invalid. This indicates an attempt to access a slot that does not exist or is not supported, preventing the command from completing successfully.

• The selected table index for 750-644 I/O modules (slots 1-7) in MBX_TARGET_TABLE_AND_INDEX (Bits 0-3) is greater than 6.
• The selected table index for Bluetooth SPP devices (slots 8-12) in MBX_TARGET_TABLE_AND_INDEX (Bits 0-3) is greater than 5.

Click steps to track your progress.

1. 1

   Review the MBX_TARGET_TABLE_AND_INDEX parameter (Bits 0-3) used with the MBX_GETUSERFRIENLYNAME command.

2. 2

   Verify that the selected table index is within the valid range: 0-6 for 750-644 I/O modules or 0-5 for Bluetooth SPP devices.

3. 3

   Adjust the table index parameter to a valid value corresponding to the target device's slot.
