Abstract

A monitoring and protection system for a machine system includes monitoring modules or groups of modules positioned at various locations of the machine system at which dynamic operating conditions are monitored. The modules are configured to communicate with one another via an open industrial data exchange protocol. Network media is routed between groups of monitoring modules to establish an overall system topology that is highly distributed and that is not dependent upon routing of multiple signal cables to central monitoring locations or racks.
