The FieldConnex fieldbus high-density power hub offers compact dimensions and needs only limited space inside the switching cabinet. Optimised circuits with low power loss result in cooler thermal conditions, which allow the positioning of the board in any direction. In comparison with the previous model, the available power supply current has increased from 360 to 500 mA per fieldbus segment.
Belden has introduced a Category 6 DataTuff twisted pair cable to its family of industrial ethernet cables. The 7940A cable is EtherNet/IP compliant and is of round construction, which makes it suitable for sealed industrial ethernet connectivity applications.
In the coal mining industry, the dragline is the workhorse of the open-cut mine's operation, moving massive amounts of overburden 24 hours a day throughout the year.
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 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.
