INSTALLING SUPERVISORY PROCESS CONTROL AND MANUFACTURING SOFTWARE FROM A REMOTE LOCATION AND MAINTAINING CONFIGURATION DATA LINKS IN A RUN-TIME ENVIRONMENT

摘要

A method is disclosed in a supervisory process control system environment for installing supervisory process control software from a central software deployment server. The software distribution method includes the step of first specifying a software component for a supervisory process control application to be deployed to a remote location (1810) and a destination for the software component based upon distributed application configuration (1860). A software component is conditionally transmitted to the remote supervisory control computer after the determining step if the software component for the supervisory process control application is not present at the remote location. In accordance with another deployment aspect of the present invention a method for maintaining a communication link to an object (1840) in a supervisory process control and manufacturing information application distributed among a plurality of locations enables a target of client object requests to be moved to a new location within the system without notifying the client objects of the target's new location (1860). The method is carried out within a system including a naming service that is accessed by the application and includes a namespace that a correlates object location independent names corresponding to object location dependent handles.
