5.1.4 Functional Specifications
The Bristol Babcock Synchronous/Asynchronous Communication Protocol
(BSAP) is the foundation for a proprietary network that has a tree structured
topology. This open-ended topology supports a variety of configurations which
may include one or more nodes at each of up to six levels. Messages can be
sent between nodes on the same level or on different levels. Messages can be
sent between nodes (local message only). Each message is uniquely identified
and has an error checking code associated with it.
Some of the general specifications include:
ƒ
Slave implementation
ƒ Support for the storage and transfer of internal database registers to/from the
ControlLogix processor's controller tags
ƒ Two ports to emulate a BSAP slave RTU
ƒ Peer-to-Peer communication for Local BSAP formatted messages - slave to
master only
