1. 1

   Inspect the Logix 5000 controller's fault log to identify the specific routine and block-transfer instruction (e.g., MSG instruction) generating the 'Invalid block-transfer request size' fault.

2. 2

   Verify the 'Element Count' or 'Length' parameter configured within the identified block-transfer instruction against the intended data payload size.

3. 3

   Compare the data structure and size (e.g., array dimensions, data type) of the target tag or device/module in the remote system with the size expected by the Logix 5000 block-transfer instruction.

4. 4

   Review the starting address and length parameters within the block-transfer instruction to ensure they do not attempt to read or write beyond the defined boundaries of the source or destination data object.
