The MVI56 Bristol Babcock Serial Slave Module allows ControlLogix I/O
compatible processors to interface easily with Bristol Babcock Serial
communication devices.

5.1.1 Features and Benefits

The MVI56-BSAPS module acts as an input/output module between the BSAP
network and the ControlLogix backplane. The module acts as a slave receiving
commands from a BSAP master device. The data transfer from the ControlLogix
processor is asynchronous from the actions on the BSAP network. An internal
database in the module exchanges data between the processor and the BSAP
network.

BSAP operates in a polled environment. Each link in the network supports a
different poll rate. The rate selected depends on a variety of application-
dependent factors.

BSAP has been designed and implemented according to the functional layers of
the International Standards Organization (ISO) model. Because each layer is
independent of its adjacent layers, both synchronous and asynchronous
transmission modes can be supported.
