isa100 Entre le Bluetooth, le ZigBee, le WirelessHART et … le ISA SP-100.11a, la transmission sans fil dans le monde industriel attire toujours plus de constructeurs et … de solutions!

Point marquant, cette solution est native IPv6 (mais est-ce intéressant vraiment en environnement industriel ?), offre une grande fiabilité de transmission ainsi qu’une excellente comptabilité avec les systèmes qui utilisent des protocoles filaires tels que Fieldbus Foundation, HART, Profibus et Modbus.

Une alternative au choix de la transmission sur réseaux Ethernet filaires et sans-fils avec ces protocoles adaptés tel que Fielbdus H1, Profinet, Modbus-TCP, Ethernet/IP… ?

Yokogawa Electric Corporation is promoting efforts to develop the ISA100.11a wireless communication standard for the process automation industry.
Despite many inherent benefits, wireless networks have seen limited use to date in the process automation industry due to 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.
Yokogawa is supporting development of the ISA100.11a standard because it has the following benefits:
– It offers high reliability to ensures safe production operations and information security.
– It is based on IPv6 and can accommodate larger networks.
– It offers excellent compatibility with existing instrumented systems that use non-wireless protocols such as FOUNDATION fieldbus, HART, PROFIBUS, and Modbus.
– It is suitable for a wide range of applications, from monitoring to control.
As a member of the ISA100 Standards Committee on Wireless Systems for Automation, Yokogawa will engage in a wide range of activities to promote development of the ISA100.11a international standard. Yokogawa will develop systems products and field devices that comply with this standard, and plans to release them in the first half of the 2010 fiscal year.
