Abstract

A system is provided for monitoring dynamic data at various points of a machine system. The monitoring system includes monitoring groups that are associated with sensors at each monitoring point. Remote control and monitoring equipment may also be provided in communication with the monitoring modules. The monitoring modules are configured for wireless communications between and among themselves. The modules may also communicate wirelessly with the remote equipment. Certain components may be connected by conventional wiring, such as for supply of power, where available. Distant monitoring points may thus be accommodated, as well as low cost or less critical monitoring points without the added cost and complexity of network wiring between the modules.
