1. A distributed system for monitoring dynamic operating conditions of a rotary machine system, comprising:
- a first monitoring group including a first sensor for detecting a dynamic operating condition at a first monitoring point of the machine system, and a first condition monitor coupled to the sensor local to the first monitoring point for processing signals from the first sensor;
a second monitoring group including a second sensor for detecting a dynamic operating condition at a second monitoring point of the machine system distal from the first monitoring point, and a second condition monitor coupled to the second sensor local to the second monitoring point for processing signals from the second sensor, and network media linking the first and second monitoring groups for data exchange therebetween, the network media including data conductors for data exchange in accordance with a predetermined network protocol.

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.
