Block Transfer Data Interface
The LSM is capable of exchanging large amounts of data with the PLC
processor via the Block Transfer mechanism. The amount of data greatly
exceeds that which could be accommodated by a single block transfer. As a
result, the data is divided into several different “files” and can be obtained
through the use of multiple Block Transfers. The sizes, structure, and
contents of the block transfer reads and writes supported by the LSM are
provided in Appendix B. See “Block Transfer Communications”, listed on
Page 4–2 in the Application Information chapter of this manual for further
details on using Block Transfers.
