The type of block-transfer request is not consistent with the expected BT_READ or BT_WRITE types. This indicates an incorrect command type was issued for the block transfer.
Click steps to track your progress.
Verify the `MSG` instruction configuration, specifically the 'Message Type' (BT_READ/BT_WRITE) and 'Data Table Address' for consistency.
Inspect the target intelligent module's configuration in the I/O tree to ensure it aligns with the block-transfer request type.
Review the ladder logic or structured text associated with the `MSG` instruction for any conditions that could issue an incorrect command type.
Check for controller and module firmware compatibility issues related to block transfer operations.
Verify the data structure (tag) utilized by the `MSG` instruction matches the expected format for the block transfer.
