Yokogawa Electric is promoting efforts to develop the ISA100.11a wireless communication standard for the process-automation industry.

Based on this standard, Yokogawa will develop a new field digital-network platform that will enhance productivity - both by eliminating the difficulties users currently face with incompatible wireless-communication protocols and by enabling the systematic integration of wired and wireless technologies.

Wireless networks offer many advantages to the process-automation industry, including reduced wiring and engineering costs, the ability to install sensors in difficult-to-wire locations and improved plant safety through the ability to perform low-cost online device diagnostics.

Despite such benefits, wireless networks have seen limited use to date in the process-automation industry, because of the requirement for advanced technologies to ensure high reliability, real-time response, environmental resistance and explosion-proof protection, and also because of the use of incompatible wireless-communication protocols.
