The Fieldbus Foundation's announced copyright agreement with Prolist International means that fieldbus parameter names and definitions will be included in standardised device specifications.
The Fieldbus Foundation, through its EMEA operations, has joined the Applied Control Technology Consortium (ACTC), based in Glasgow, Scotland. Through this membership, the ACTC will undertake a program of formal, quantitative evaluations of Foundation Fieldbus technology.
ABB has announced its Extended Automation System 800xA was recently registered as an initial Foundation fieldbus host system after it passed the Fieldbus Foundation’s rigorous new Host Profile Registration Process.
GE Fanuc Intelligent Platforms has announced the NETernity RM983RC VME ethernet switch. Designed for demanding network switching applications in industrial, government, telecommunications and defence applications, the 6U form factor RM983RC switch provides support for 12 or 24 gigabit ethernet ports. It ships with GE Fanuc’s OpenWare Lite switch management environment, providing customers with the flexibility to manage configuration of the RM983RC from a serial console or via the network.
Fieldbus is a wonderful technology with many benefits, but fieldbus installation requires some additional considerations over and above normal 4–20 mA projects, not the least of which is how to prepare for fault conditions.
Yokogawa's Stardom and Centum VP control systems, and ABB's System 800xA extended automation system, are the first host systems to pass the Fieldbus Foundation's Host Profile Registration Process.
The ConneXium industrial ethernet infrastructure family includes industrial switches, hubs, transceivers, cables and tools. In addition, it features industrial protocol-to-ethernet gateways, such as MB to ethernet and MB+ to ethernet. The family of products also includes industrial ethernet software tools, such as the ConneXview ethernet diagnostic tool.
The SIL2-rated RN221N combined active barrier and power supply provides galvanic isolation for 4–20 mA measurement signals, is suitable for use in hazardous areas, and can be powered by 20-250 VAC/DC, reducing the need for different versions across the plant.
The EKI-1220 series Modbus Gateways are designed for quick and easy integration of Modbus serial devices with industrial ethernet networks. Available in two configurations, the EKI-1221 and EKI-1222 feature one or two RS232/422/485 serial ports, with redundant 10/100 Mbps ethernet connections, for transparently connecting Modbus ASCII/RTU and Modbus/TCP devices and equipment.
Belden has introduced the category 5e DataTuff SI7938A shielded twisted pair continuous flex cable for use in continuous motion machinery, such as C-Track and festoon systems, as well as robotics frequently used in discrete manufacturing and automated assembly lines. It features a flexible, stranded and shielded construction to resist machine and plant floor vibration, along with high noise immunity.
Fieldbus (the use of digital communications networks for distributed instrumentation and control) is a wonderful technology with many benefits, but fieldbus installation requires some additional considerations over and above normal 4–20 mA projects.
