Communications/Telemetry
In addition to the benefits of better process management, RWE is saving 10 per cent per year on its total maintenance costs. Remote online access to diagnostic information enables operators to identify potential instrument problems earlier and correct them before poor measurements start to affect the process. Access to online data has also reduced the number of trips into the field, helping to improve the safety of equipment and workers.
Wireless anywhere Yokogawa has introduced a new ‘Wireless Anywhere’ business concept on the plant-wide use of ISA100.11a-compliant wireless communication technologies for both monitoring and control applications. Te company says it will promote this concept to widen the use of ISA100.11a-compliant products and related services. Te ISA100.11a standard ensures high reliability, application flexibility, network expandability, and compatibility with a variety of wired communication standards such as FOUNDATION fieldbus, HART, and PROFIBUS. ISA100.11a full functional field wireless network systems and devices make use of state-of-the-art dual redundant technologies that enable a much higher level of reliability, and allow massive scalability and long- range communications. Yokogawa says it will pursue three initiatives to drive the concept on:
● Modularising wireless components to accelerate product development. Tis 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 the company plans to begin releasing new field wireless devices with these components.
● Promoting adoption of the ISA100.11a standard by working with other members of the ISA100 Wireless Compliance Institute (ISA100WCI) to increase the number of WCI companies and promote acceptance of the ISA100.11a standard, thereby expanding the field wireless market.
● Facilitating host connectivity for both wired and wireless field networks. Yokogawa says it 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. Tis will necessitate the development of technologies that will 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. ●
