The Fieldbus Foundation (FF) and International Specialty Products (ISP) demonstrated the full implementation of FF's open, integrated FOUNDATION fieldbus architecture on May 19 at ISP's 1, 4-butanediol (BDO) plant. The event showed how fieldbus H1, high-speed Ethernet (HSE) and flexible function blocks (FFB), integrated with OPC, form an open, interoperable plant infrastructure to improve process performance, and deliver operating and capital savings in new and renovated applications.
For the live BDO demonstration, a FOUNDATION fieldbus system consisting of H1 field devices and HSE linking devices was installed on a vapor system at the Lima plant. The fieldbus controls actuated a series of butterfly valves used on the process. The demo highlighted FFB implementation of host-resident logic using discrete and analog field devices residing on H1, the co-existence of diverse control systems from various manufacturers using HSE, and the interoperability of alternate HSE linking devices and associated controllers. In addition, the application showed the suitability of existing FOUNDATION fieldbus devices for high-speed batching and sequencing of discrete systems, as well as the use of FFBs in discrete and hybrid applications.
John Rezabek, lead controls engineer at ISP's Lima facility, reports that the FOUNDATION fieldbus demonstration project provided valuable, real-world experience for end-users seeking to replace proprietary control systems with an open, interoperable fieldbus architecture for reliable control at the field level. "The distinct advantages of implementing H1 and HSE in lieu of proprietary networks will become increasingly apparent, as our leading suppliers develop products to make this technology accessible to their customers everywhere," he says.
The demo was a joint project initiated by BP Amoco Chemical Co., an indirect subsidiary of BP plc, and the foundation. ISP, through one of its subsidiaries, acquired BP's BDO operations in March 2005. The Lima plant has an annual capacity of 60,000 metric tons of BDO, which is a key building block for specialty chemicals products used in pharmaceutical, personal care, food, beverage, coatings, oil field and other applications. ISP produces more than 400 specialty chemicals and performance-enhancing products.
FF members participating in the demonstration project included ABB, Emerson Process Management, Fieldbus Center at Lee College, Hawke, Hirschmann, Honeywell, Invensys, MTL/Relcom, Pepperl+Fuchs, Phoenix Contact, Rockwell Automation, Smar, Softing, StoneL, TopWorx, Turck, Yamatake, Yokogawa, and Westlock.
Developed for FOUNDATION fieldbus HSE (100 Mbps) technology program, but also compatible with H1 (31.25 kbps) fieldbus systems, FFBs are a key component of the FOUNDATION architecture for plantwide information integration. FFBs, which are application-specific, bring the full instrumentation integration part of the fieldbus solution into play. They reside at the fieldbus user layer along with standard function blocks, and enable control strategies, such as supervisory data acquisition, batch control, programmable logic controller (PLC) sequencing, coordinated drive control, and input/output (I/O) interfacing—including gateways to other plant device networks.
