YSS2000: a configuration software system for industrial monitoring and controlling

As a configuration software system for industrial monitoring and controlling, YSS2000 is implemented. It consists of three subsystems for effective and convenient usage. For compatibility to different device types, the device configuration subsystem provides message format configuration and variable configuration. For high real-time, reliability, stability and safety in the running subsystem, the data management structure is composed of two parts (real-time database in memory and history database in disk); in the communication module, the structure of message sending and receiving queues is maintained; and double online standby technology is applied. A configuration language C2000 enables users to configure complicated and powerful functions.
