These new wireless products can be used to construct highly reliable large-scale plant networks, and may also be incorporated in small- and medium-sized networks that already utilize our existing products, substantially expanding their capability. This is in line with our “Grow” concept of enabling customers to expand their plant wireless networks while making full use of existing assets.
A wireless network that connects a control system with field devices such as differential pressure/pressure transmitters and temperature transmitters has many advantages: it reduces cabling and other installation costs, and allows the installation of equipment in difficult to wire locations.
In July 2010, Yokogawa began offering entry-level field wireless system solutions based on the YFGW710 field wireless integrated gateway. Users of these systems have come to value their high reliability, real-time performance, and environmental resistance, which help ensure stable plant operations, as well as their immunity to electromagnetic interference and secure wireless communications. A number of these users now wish to expand their wireless networks.
To meet this demand for large and reliable plant wireless networks, we have developed three new field wireless system devices and enhanced two existing field wireless transmitters.
