What’s New with the Standard Interchange Protocol?
This document describes Version 2.00 of the 3M Standard Interchange Protocol. Version 2.00 builds on top of Version 1.00 of the protocol, adding new messages, and new fields to already-existing messages. All new messages and fields are indicated by having “2.00” in front of them in the message definitions. Any messages and fields that are not prefixed by “2.00” existed in earlier versions of the protocol.
