Enhanced network computing-seamless integration of control network and information network

摘要

Information infrastructures for business systems have already established facilities which makesystems network-wide and open. These facilities are being set up for control and monitoring systems. Toshiba has proposed an open system architecture called enhanced network computing (ENC)for control and monitoring systems. ENC seamlessly integrates control networks and businessnetworks by adopting the platform-independent, object-oriented Java technology for theLONWORKS (LON) distributed control network. ENC consists of the process network computing(PNC) control node and the PNC server as hardware components, together with ECJ{sub}* (EventCentric for Java), JSAS (Java Standard Application Set), and JDevice as software components.
