Passerelle Modbus série/Ethernet chez B&B ElectronicsB&B Electronics sort une passerelle Modbus série/Ethernet permettant une intégration des anciens équipements séries Modbus avec les versions Ethernet qui utilisent le protocole Modbus-TCP et facilitant donc les étapes de migration.

Des versions cuivres et fibres optiques sont disponibles en boitier industriel (rail-din et alimentation en 12, 24, 48V).

Do you need a quick and easy solution to integrate older Modbus serial equipment with your Modbus/TCP network?

B&B Electronics announces their new Vlinx™ Industrial Modbus Ethernet-to-Serial Gateways. MESR series gateways are a costeffective way to connect serial Modbus ASCII/RTU devices with Modbus/TCP Ethernet as well as solve many other real-world Modbus problems such as converting ASCII to RTU, remapping conflicting Modbus ID’s or connecting two Modbus devices hardwired with different baud rates. With zero-tolerance for unexpected downtime on today’s factory floor, these Modbus gateways, designed and built by B&B Electronics, offer peace-of-mind for plant operation managers around the world.

Vlinx Modbus Gateways boast an extensive line-up of Ethernet port configurations – from standard RJ-45 copper to almost any fiber optic option. Versions are available with an additional Ethernet port that functions much like an Ethernet switch, allowing pass-through connectivity for other Ethernet devices. The port can also be used to “daisy chain” multiple gateways.

Serial ports can be accessed over a LAN/WAN using Direct IP Mode connections. Serial data rates up to 230 kbps ensure maximum network flexibility. Easy to use software supports Modbus messaging priority control and management via multiple TCP/IP client sessions. Rugged MESR gateways feature a slim IP30 DIN mount case, pluggable terminal blocks, and 10-58 VDC operation.

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.
