Chemicals manufacturer, Avecia, is to commence trials on the use of fieldbus in hazardous area applications, using plug-and-play technology from ABB Automation.

The trials are to take place on two plants producing agro-chemicals and pharmaceuticals intermediates at Avecia’s Grangemouth site in Scotland, where ABB AC800 FieldControllers with integrated Profibus communications will monitor the usage of steam, water and nitrogen. The applications engineering is being carried out by ABB in collaboration with a partner in Scotland, JW Fairbairn.

The ABB AC800 FieldController performs all the data acquisition and mass flow computations and is a component part of ABB’s recently introduced range of Industrial IT suite of products and services. It provides Avecia with a cost-effective entry level for Profibus, the company’s choice of communications protocol, and offers the open systems capability for seamless integration with the site Scada package and various new and third-party devices.

Engineers no longer need to go out on to the plant to check field instruments with hand-held terminals. The ABB Field Controller can be used with Profibus to configure and parameterise any make of fieldbus instrument from a single point. This is performed by ABB’s DigiTool, a single, IEC 1131-3-compliant engineering tool which provides for homogenous configuration, commissioning and diagnostics from the sensor up to the graphic display.

The installation includes intrinsically safe (IS) Profibus PA flow and temperature instrumentation from ABB and third-party vendors, along with ABB S800 remote I/O for converting into Profibus DP traditional 4-20mA signals from existing pressure transmitters.
