Abb presents the station computer com615 combines the features and functionality of the control and monitoring unit com605 and the communication gateway com610. Com615 provides gateway functions for mapping signals between protection and control ieds in industrial or utility substations and higher-level systems, and an hmi [human machine interface] that provides an interface for data and information between the substation and the users. Com615 gathers the data from protection and control ieds as well as process devices using different communication protocols. Control and monitoring data are displayed to different users in a well-arranged and user-friendly manner utilizing standardized web technology and transferred to the network control centre or distributed control system.
