The WirelessHART standard provides a robust wireless protocol for the full range of process measurement, control and asset management applications.
In the Part 1 of this article, Joel Young explored cellular, Wi-Fi/802.11 and WiMAX/802.16 technologies. In this second part, he examines ZigBee/802.15.4 and provides some guidelines for planning a successful commercial or industrial deployment.
Joel Young explores how to mix different wireless technologies, including cellular, Wi-Fi/802.11, WiMAX/802.16, ZigBee/802.15.4 and proprietary wireless, to form a successful commercial or industrial deployment.
Emerson Smart Wireless technology is enabling polyethylene maker INEOS to detect blocked filters within polyethylene pellet transportation tubes that can lead to production downtime at its plant in Cologne, Germany.
At Terminals Pty Ltd’s facility in Geelong, bitumen is unloaded from ships through a pipeline 900 m long and 200 mm in diameter. Wireless temperature monitoring helps keep the bitumen heated so it doesn't solidify in the pipe.
The EKI-1351 (1-port) and EKI-1352 (2-port) 802.11b/g wireless device servers allow RS232/422/485 serial devices to be remotely monitored, managed and controlled wirelessly, eliminating the need for hardwired cable connections.
Industrial users have historically been a bit cautious about taking advantage of wireless technology. This caution is generally due to concerns related to critical infrastructure security and reliability. However, if the right wireless solution is chosen, adopters of industrial wireless technology can have the best of both worlds.
CSIRO and Tasmanian-based Datacall Telemetry have commercialised the Fleck wireless sensor network, which allows the real-time collection of data from large areas via mobile phone or internet connection.
Digi International has introduced DigiMesh on 900 MHz and 2.4 GHz XBee-embedded RF modules, providing mesh networking support for processes using battery-powered devices.
The WirelessHART Communication Specification (HART 7.1) has been approved by the International Electrotechnical Commission (IEC) as a Publicly Available Specification (IEC/PAS 62591Ed. 1), making it the first officially released industrial wireless communication standard.
Extending the mantle of safety — The role of IP-centric satellite communications in managing security risk in remote area mining operations20 September, 2008 by Chris Hill*
Operating a mining operation in a remote area, especially in a country with significant infrastructure shortcomings, presents a series of challenges which must be addressed at a strategic level, in order to ensure the long-term sustainability and viability of such operations. A reliable communications platform directly back to the corporate head office provides a solid foundation for effective command and control, supporting not only day-to-day administrative and production operations, but also as-needed communications pathways for emergency management.
ProSoft Technology’s industrial frequency hopping serial radios are licence free and are available in both the 900 MHz (RLX-IFH9S) and 2.4 GHz (RLX-IFH24S) bands. Frequency hopping radios use a proprietary signal that hops from channel to channel, which provides the wireless network with an extra layer of security allowing it to avoid interference or existing wireless networks.
Banner Engineering has announced the SureCross DX70 Wireless Developer’s Kit, consisting of a gateway and one node transceiver to enable on-site wireless testing. The ready-to-use, self-contained kit provides battery boxes with test buttons and indicator lights simulating inputs and outputs to determine an application’s specific range and response time requirements.
