BB-400 IO and Protocols
The BB-400 provides a variety of protocols that can be used to receive and modify the status of the IO lines. The IO protocols available are REST, WebSockets, Unix Domain Socket and ASCII TCP.
The BB-400 allows connections to multiple protocols at the same time, over different devices. Changing the state through one API will allow changes to be reflective over other protocols. The image below shows an example of the connections possible from the server, the BB-400 and a range of different clients, the protocols.
The following table lists the connection characteristics of each protocol available on the BB-400:
|Max number of commands/sec||400||150||350|
|Average response time (for 1 user)||2.7 ms||11 ms||2.5 ms|
|Max number of simultaneous connections||200||n/a||10|
