Borges said, "For Petrobras, the primary objective of this live demonstration at the pilot plant PC3 was to verify that we could access and use remotely, with ROM, all the operational functionalities available locally. Another objective was to check the interoperability of ROM devices of different manufacturers over the backhaul."
He added, "ROM provides very easy and quick integration, and is transparent to the user."
The demonstration took place inside the Center for Collaborative Visualization (NVC), also known as "The Egg," a spherically shaped building that houses a center for high-fidelity 3-D training simulation. Because of the remote capabilities of FOUNDATION for ROM, participants were able to use the meeting room as a virtual control room, showing live video feed from multiple locations in the pilot plant and wireless device diagnostic information all within the FOUNDATION fieldbus infrastructure. Information from the pilot plant in another part of the Cenpes compound was communicated across the High Speed Ethernet (HSE) wireless backhaul network to the virtual control room in the meeting room over standard Ethernet hardware and wireless equipment, as well as standard cyber security appliances.
The press day event started off with some introductory words from Petrobras Cenpes Executive Manager Marcos Isaac Assayag and introduction of participating vendors and press from Fieldbus Foundation Marketing Manager Larry O'Brien. Fieldbus Foundation President and CEO Rich Timoney and Chairman Dr. Gunther Kegel also provided some key opening remarks.
According to Dr. Kegel, the world of automation is entering the age of Cyber Physical Systems, or the "Internet of Things" for automation, if you will. FOUNDATION for ROM is an enabler for cyber physical systems in process automation because it has the ability to consolidate diagnostic information from a number of disparate networks and can manage that information effectively in a single infrastructure that can be shared wirelessly through standard Ethernet and IP technology.
ROM solution brings it all together
Fieldbus Foundation's Larry O'Brien gave a brief description of how FOUNDATION for ROM does this, as well as the business requirements addressed by ROM. According to O'Brien, FOUNDATION for ROM was designed to enable fieldbus connectivity to remote I/O and the leading industrial wireless protocols, and is the first successful integration of ISA100.11a, WirelessHART, wired HART, and wired H1 protocols into a single standard environment without sacrificing the diagnostic capabilities of existing wireless devices. Instead, these capabilities are mapped into the FOUNDATION block structure to provide a standard environment for data management and quality, eliminating techniques that are highly customized and much more costly to maintain throughout the plant lifecycle.
O'Brien indicated that FOUNDATION for ROM takes full advantage of the FOUNDATION fieldbus HSE-based network, which shares the same architecture as the H1 field network technology. With FOUNDATION for ROM, the HSE backhaul network is the "glue" that brings other networks together into a single managed infrastructure.
John Rezabek, chairman of the Fieldbus Foundation End User Advisory Council (EUAC), then gave a presentation on the value of FOUNDATION fieldbus and FOUNDATION for ROM to the end user. Rezabek used the "Walled Garden" analogy of Apple to describe the proprietary approach that many have taken to process automation, stressing that the value of FOUNDATION fieldbus lies in the fact that it was created with the guidance of end users, and its evolution continues to be heavily influenced by the EUAC, FOUNDATION for ROM included.
How the demo equipment operated
The second half of the day consisted of presentations from Petrobras personnel and the Fieldbus Foundation's demo project leader for Brazil, Libanio De Souza from Smar in Brazil. Renato Ogeda, equipment manager at the Cenpes plant, gave an overview of the Cenpes facility. De Souza then gave a demonstration of the ROM functionality, including more details on how FOUNDATION fieldbus brings diagnostic information from devices on other wireless and wired networks through the FOUNDATION block-based structure.
FOUNDATION for ROM adds a new function block to provide an efficient way to bring large concentrations of discrete and analog field I/O back to the control room using HSE communication. The new Association Block can aggregate 64 discrete inputs/outputs and 16 analog inputs/outputs. There is also a new function block for WirelessHART that includes HART statuses. FOUNDATION for ROM may be embedded into existing devices including RTUs, controllers, PLCs, PACs, and wireless gateways.
Device status is reported using the NAMUR NE 107 framework, based on five states:
