New wireless infrastructure and instrumentation platform
Yokogawa Electric Corporation has announced its new Wireless Anywhere business concept on the plant-wide use of ISA100.11a-compliant wireless communication technologies for both monitoring and control applications. Yokogawa will promote this concept to widen the use of ISA100.11a-compliant products and related services. The company says this effort will augment its existing “Grow” concept, which encourages wireless communication technologies by making a case for their inherent reliability, flexibility, and openness.
Yokogawa says it has adopted the ISA100.11a standard due to its high reliability, application flexibility, network expandability, and compatibility with a variety of wired communication standards such as Foundation fieldbus, HART, and Profibus. The standard makes use of state-of-the-art dual redundant technologies that enable a high level of reliability, allow massive scalability, and long-range communications.
Yokogawa’s growing program will pursue three main initiatives:
1. Modularizing wireless components to accelerate product development—Yokogawa will develop modularized wireless components that incorporate the various technologies in its field wireless devices. This will make it easier for vendors to implement the ISA100.11a technology in new sensor products and accelerate time to market. By the end of 2013, Yokogawa plans to begin releasing new field wireless devices with these components.
2. Promoting adoption of the ISA100.11a standard—Yokogawa will work with other members of the ISA100 Wireless Compliance Institute (ISA100WCI) to increase the number of WCI member companies and promote acceptance of the ISA100.11a standard, thereby expanding the field wireless market. To make a wider range of ISA100.11a-compliant products available to the market, Yokogawa may supply modularized components to other vendors.
3. Facilitating host connectivity for both wired and wireless field networks—To encourage use of field wireless systems in both monitoring and control applications, Yokogawa will seek to improve the effectiveness of plant-wide field digital networks by making it possible for wired and wireless field devices and systems to connect with host monitoring and control systems. This will drive development of technologies to ensure host systems and field devices can communicate with each other using a variety of protocols. For example, an ISA100.11a-compliant adapter would enable a wired field device to link up with a wireless network.
Such systems ensure responses in real time by making use of state-of-the-art dual redundant technologies and can be quite large in scale, supporting connections to up to 500 wireless field devices. The data update time is five seconds when the system consists of a host system and 500 field devices, and one second with a host system and 200 field devices. With appropriate configuration and antenna selection, such wireless devices are proven to be able to communicate over distances up to 10 km under favorable conditions.
