Abstract

An integrated monitoring, control and equipment maintenance and tracking system and method is provided for managing a plurality of field devices. The integrated and coordinated system includes the monitoring and control system that uses safety subsystem field device data and process control subsystem field device data. When a compromised field device is determined, e.g., by the safety system and/or the process control system, information about testing, maintenance, repair or replacement is conveyed to the monitoring and control system. This information is used to modify the work orders created by the equipment maintenance and tracking system processor such that the compromised field device, or a field device at a location of the compromised field device, is not subject to unnecessary or excessively redundant testing.

Claims

1. An integrated monitoring and control system and equipment maintenance and tracking system for managing a plurality of field devices, the field devices including safety subsystem field devices associated with one or more processes or subprocesses and process control subsystem field devices associated with one or more of the processes or subprocesses, the integrated monitoring and control system and equipment maintenance and tracking system comprising:

a monitoring and control system including

a monitoring and control system memory that stores

safety subsystem field device data and

process control subsystem field device data,

a monitoring and control system processor coupled to the monitoring and control system memory;

a status receiving module executable by the processor for receiving a signal from a compromised field device; and

an instruction generating module executable by the monitoring and control system processor for generating instructions to test, repair or replace the compromised field device; and

an equipment maintenance and tracking system in communication with the monitoring and control system including

an equipment maintenance and tracking system memory that stores field device maintenance work orders;

an equipment maintenance and tracking system processor coupled to the equipment maintenance and tracking system memory; and

a maintenance work order modification module executable by the equipment maintenance and tracking system processor that modifies a work order for the compromised field device, or a field device at a location of the compromised field device, based on instructions generated by the instruction generating module of the monitoring and control system processor.

2. The integrated monitoring and control system and equipment maintenance and tracking system of claim 1, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has undergone functional testing.

3. The integrated monitoring and control system and equipment maintenance and tracking system of claim 1, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has undergone repair.

4. The integrated monitoring and control system and equipment maintenance and tracking system of claim 1, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has been replaced.

5. An integrated monitoring and control system and equipment maintenance and tracking system for managing a plurality of field devices, the field devices including safety subsystem field devices associated with one or more processes or subprocesses and process control subsystem field devices associated with one or more of the processes or subprocesses, the integrated monitoring and control system and equipment maintenance and tracking system comprising:

a monitoring and control system including

a monitoring and control system memory that stores

safety subsystem field device data and

process control subsystem field device data,

a monitoring and control system processor coupled to the monitoring and control system memory;

a status receiving module executable by the processor for receiving a signal from a compromised field device; and

an instruction generating module executable by the monitoring and control system processor for generating instructions to test, repair or replace the compromised field device; and

an equipment maintenance and tracking system in communication with the monitoring and control system including

an equipment maintenance and tracking system memory that stores a field device routine maintenance schedule;

an equipment maintenance and tracking system processor coupled to the equipment maintenance and tracking system memory; and

a schedule modification module executable by the equipment maintenance and tracking system processor that modifies the field device routine maintenance schedule for the compromised field device, or a field device at a location of the compromised field device, based on instructions generated by the instruction generating module of the monitoring and control system processor.

6. The integrated monitoring and control system and equipment maintenance and tracking system of claim 5, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has undergone functional testing.

7. The integrated monitoring and control system and equipment maintenance and tracking system of claim 5, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has undergone repair.

8. The integrated monitoring and control system and equipment maintenance and tracking system of claim 5, wherein the instruction generating module of the monitoring and control system generates instructions based upon the date the compromised field device has been replaced.
