Emerson Process Management has unveiled the compact 1410D Smart
Wireless Gateway for wireless network applications, where gateway installation locations are limited, in difficult safe areas that must connect to distant wireless application networks.
Tata Steel has also been trialling wireless adapters fitted to a pair of pressure transmitters so they can communicate with one another, and with the plant's control system via a
wireless gateway. "We've installed a mesh of instruments around the blast furnace to test how they cope," Kumar said.
Thanks to the
wireless gateway, data can flow both ways--to or from the mobile device.
In this type of set-up, the optical fiber infrastructure is used up to its ending point and then connected to a
wireless gateway. This gateway converts the optical data to electrical millimeter-wave signals that feed an antenna.
Flow data is transmitted every 30 seconds and pressure and level data every 300 seconds to a Smart
Wireless Gateway positioned on the control room roof.
The solution includes the following products: meshed access network - ZoneFlex 7762, a dual-band 802.11n Smart Wi-Fi outdoor access point, and ZoneFlex 2741, an 802.11g Smart Wi-Fi outdoor access point; high-speed wireless backhaul - ZoneFlex 7731, a new point-to-point 802.11n (5GHz) backhaul system; customer premises equipment - MediaFlex 2200, a purpose-built
wireless gateway that extends Wi-Fi signals indoors; remote Wi-Fi service management - FlexMaster remote Wi-Fi systems management platform.
An Emerson Smart
Wireless Gateway was positioned on the roof of a technical building around 300m from the devices.
The SmartPack kit includes a Model 1420
Wireless Gateway, a 25-tag license for AMS Device Manager software, 5-100 wireless devices, Emerson-supplied SmartStart[TM] installation services and five wireless instruments.
