TOSWACS{sup}TM -F{sub}X process supervisory control for water and sewage plants

摘要

Conventionally, it has been necessary to use dedicated hardware and software when implementing a process supervisory control system, in order to obtain sufficient performance. However, the new TOSWACS{sub}TM-F{sup}X process supervisory controlsystem for water and sewage plants incorporates many de facto standard (DFS) technologies. The TOSWACS{sub}TM-F{sup}X realizes real-time functionality and high reliability while benefiting from the many merits of adopting these DFS technologies.This paper introduces the TOSWACS{sub}TM-F{sup}X system, describing the merits of adopting DFS technologies, improvements made to these DFS technologies, and an example of application.
