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.
