Problems solved by technology

[0006] Unlike the physical interlocks that exist in many industrial environments, there is no coordination on site associated with the process automation system between the master control system used to control the process and the asset management system used to track and maintain the process plant The formal method of "locking" the instrument

Embodiment Construction

[0024] now refer to figure 1 , the exemplary process plant 10 includes an integrated system for coordinating software locks between process control systems and asset management systems within the plant environment. Typically, process plant 10 includes a distributed process control system (also known as a "distributed control system" or "DCS") having one or more process controllers 12, each of which may include a redundant pair of controller. Each process controller 12 is connected to one or more field devices 14, 15, and 16 via input / output (I / O) cards or devices 13, 18, and 19, which may follow any desired communication or controller protocol for any type of I / O device. Field devices 14, 15, and 16 may be any type of field device, such as sensors, valves, transmitters, positioners, etc., and conform to any desired open, proprietary, or other communication or programming protocols.

[0025] The process plant 10 also includes one or more user interfaces or computers 20, 22 (...

Abstract

A process control system coordinates with an associated asset management system to implement a plant safety mechanism and, in particular, to prevent unintended changes to, or otherwise undesired operation of, one or more process control equipment resources in a process plant. A maintenance technician uses the asset management system to request access to one or more of the process control equipment resources. A process operator receives the request via the process control system and grants or denies the request. Process control equipment resources for which a process operator grants a request are inoperable, in part or in whole, by the process control system. Upon completion of the maintenance task, the maintenance technician requests to return control of the process control equipment resource to the process operator. The return is complete when the process operator acknowledges the return of the resource to the process control system.

Description

technical field [0001] The present invention relates generally to process control systems and, more particularly, to a software lock coordination between a process control system and an asset management system. Background technique [0002] Process control networks, such as, for example, those used in chemical, petroleum, or other processes typically include a centralized process controller communicatively coupled to one or more field devices, which may be, for example, valve positioners, switches, and Sensors (for example, temperature, pressure, and flow rate sensors), etc. These field devices may perform physical control functions within the process engineering (such as opening and closing valves), may take measurements within the process plant for use in controlling the operation of the process plant, or may perform any other desired function within the process plant. Process plants may also include various other devices such as reactor tanks, filters, dryers, generators...
