Abstract
In order to reduce investment cost of revamping an existing plant for digital transformation of field-level networks in the age of Industrial Internet of Things (IIoT), reusing existing Highway Addressable Remote Transducer (HART) field devices can become suitable with a solution through modification of process control loop. This paper aims to provide a practical technique based on IEC 61804 standard for integrating HART measuring device and Foundation Fieldbus (FF) H1 actuating device into a modern distributed control system (DCS) to work together in a proportional-integral-derivative (PID) control. A temperature control loop configured and operated on the DeltaV DCS is utilized as a descriptive case study to demonstrate the workability of the proposed technique. The combined HART-FF H1 solution can be useful in detailed engineering design of revamp projects to consider whether existing HART field devices will be reused to save on instrumentation costs. Experimental results verify that the studied temperature process can be controlled by employing the proposed technique, which allows users to select for assigning the control function block to locate between the host controller and the FF H1 actuating device.
