SEAMLESS INTEGRATION OF PROCESS CONTROL DEVICES IN A PROCESS CONTROL ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To promote seamless integration of process control devices in a process control system.;SOLUTION: An integrated seamless diagnostic device 1 collects diagnostic data related to the operation of one communication link which supports one process control protocol. The collected diagnostic data is communicated to other entities in the process control system via another communication link which supports a different process control protocol. As a result, problems related to the communication link monitored by the integrated seamless diagnostic device can be reported to the appropriate entities in the process control system as they occur and without unwanted delay. Moreover, problems relating to the communication link to be monitored can be communicated to the appropriate entities via process control protocols which can be understood by those entities, without consuming the potentially valuable resources of the communication link to be monitored.;COPYRIGHT: (C)2012,JPO&INPIT
