Abstract

System and method for verifying a monitoring and protection system'"'"'s (MPS) configuration and installation are disclosed. The MPS includes a plurality of input/output (I/O) channels configured to couple to at least one sensor sensing machinery operations, an analog-to-digital converter (ADC) communicatively coupled to the plurality of I/O channels, where the ADC is configured to receive at least one signal from the plurality of I/O channels communicated by the sensor and is configured to convert the signal to a digital data. The MPS also includes a processor communicatively coupled to the ADC, where the processor is configured to derive a state based on the digital data, and an excitation system communicatively coupled to the ADC, where the excitation system is configured to excite an excitation signal for a selected system state as a replacement for the signal.

a plurality of input/output (I/O) channels communicatively coupled to at least one sensor sensing machinery operations;

an analog-to-digital converter (ADC) communicatively coupled to the plurality of I/O channels, wherein the ADC is configured to receive at least one signal from the plurality of I/O channels communicated by the at least one sensor and is configured to convert the at least one signal to a digital data;

a processor communicatively coupled to the ADC, wherein the processor is configured to derive a state based on the digital data; and

an excitation system communicatively coupled to the ADC, wherein the excitation system is configured to excite an excitation signal for a selected system state as a replacement for the at least one signal.

2. The monitoring and protection system of claim 1, comprising a verification and validation reporting system configured to dynamically generate a report displaying a response of a component of the monitoring and protection system, an external system, or a combination thereof, to the excitation signal.

3. The monitoring and protection system of claim 1, wherein the system states comprise OK-NoAlarms, NotOK, Alert, Danger, Overspeed, Underspeed, Deltaspeed, or a combination thereof.

4. The monitoring and protection system of claim 1, wherein the excitation system is included as an ADC component.

5. The monitoring and protection system of claim 1, wherein the excitation system is configured to utilize a password-protected security protocol.

6. The monitoring and protection system of claim 2, wherein the verification and validation reporting system is configured to communicate the report to external systems.

7. The monitoring and protection system of claim 1, wherein the excitation system comprises one or more manufacturer configured scenarios of system state signals.

8. The monitoring and protection system of claim 1, wherein the excitation system comprises one or more user-configurable scenarios of system state signals.

9. The monitoring and protection system of claim 1, comprising a first component, wherein the first component is configured to process the excitation signal in lieu of a replaced sensor signal transmitted via the at least one sensor.

10. A computer-readable medium storing non-transitory computer instructions, the computer instructions configured to:

select one or more desired system states correlative with machinery operations;

excite one or more excited signals based on the one or more selected system states;
