Machinery Condition Assessment Module
First Claim
1. A machine condition assessment system comprising:
- (a) a standard industrial communications network;
(b) at least one signal processing engine on the network, the signal processing engine coupled to a sensor to receive raw dynamic operating condition signals and to produce processed dynamic operating condition signals representative of a dynamic operating condition of a monitored machine;
(c) a machine condition assessment module having a processor;
at least one network interface connecting the processor to the standard industrial communications network; and
a memory communicating with the processor and holding a stored operating program; and
a stored template program;
the operating program executing on the processor to;
(i) identify at least one type, location, and access method for dynamic operating condition data from a signal preprocessor required to evaluate a specific condition for which the template is designed;
(ii) identify at least one network address for an output signal indicating an alarm condition;
(iii) execute combinatorial logic from the template accepting as arguments the dynamic operating condition data and producing as a value the output signal transmitted on the network;
whereby the condition of the machine may be monitored.

Abstract
A machine condition assessment module may be integrated with standard industrial control and communications networks to receive dynamic operating data from signal processing engines and optionally process data from controlled machinery and to operate on that data according to standard and user customized rule sets to produce an assessment of the presence and severity of specific electrical and/or mechanical faults. The output of the assessment module will be, for each of the one or more machines monitored, and for each of the one or more faults assessed, a single parameter that indicates the presence and severity of the fault. This data, in turn, may be readily communicated to an industrial controller on the network for use in effecting the control process itself.
