The Communications Simulator and Analyser System (CSA) is a versatile and generic data communications simulator and analyser. It provides the capability to interactively simulate and analyse message-based communications between any number of system components or sub-systems. The CSA system supports a multitude of protocols and communications media including Fibre Distributed Data Interface (FDDI), Ethernet, RS422 (HDLC) and RS232. Functions The functions of the CSA are :
Features The features of the CSA are as follows :
CSA Components The main CSA components are the Man-Machine Interface (MMI) and Data Repository (DR) running under Windows NT and the CSA Engine running on a VxWorks real-time platform. The DR is based on a standard SQL database. All these components are housed in a standard PC-style housing with standard I/O connectors for mouse, keyboard, display monitor and network interfaces. CSA Architecture The message-based communication model derives from the different layers of data and information as shown.
CSA Information Model The user can define his own data types, as well as message parameter types. Messages are created by arranging message parameters in the required order. Message parameters can be grouped to provide discrimination for header, trailers, etc. The transmit characteristics for any message are user-definable. The HMI is Windows NT-based. User-defined function generators can be used to provide variable values for the transmitted messages. Applications
