En résumé, il vous faut des composants Ethernet durçi qui autorise un fonctionnement dans des conditions difficiles : température élevée, CEM importante, faible emplacement, environnement agressif et haute fiabilité.
Un switch IP67 (c.a.d. étanchéité totale à la poussière et capable de fonctionner pendant 1/2h sous un mètre d’eau), capable de fonctionner par tout temps, sur une façade d’un bâtiment, avec une connectique adaptée (comme le M12) permet une mise en service à coût réduit(installation et câblage).
Associez y des mécanismes de redondance spécifique au monde industriel, de contrôles d’accès et d’authentification, de commutation à vitesse filaire, de mécanisme de filtrage évolué (IGMP), de facilité de mise en oeuvre et d’administration (Web, SNMP), et vous aurez une solution pérenne, performante et fiable.
In future, standardised, low-cost transmission technologies such as Industrial Ethernet and TCP/IP will increasingly be used in the close-to-machine process levels which were previously dominated by field bus systems such as Profibus, CAN, or Interbus. The prerequisite for this is hardened Ethernet components which are able to cope with harsh factory floor conditions, and operate there fault-free over the long term.
In addition to an IP 67 switch, an appropriately robust and compact M12 connector is required to guarantee reliable real time transmission with high availability. This results in reduced installation and wiring costs, by using switches directly in the field. But this demands the appropriate intelligent, manageable, hardened Ethernet switches which are also able to provide redundancy mechanisms such as HIPER-Ring or network access control according to IEEE 802.1X
Standardized 4-pin M12-D technology for the connection of terminal equipment Totally encapsulated design Management via SNMP v1, v2, v3, Web GUI or Telnet Support for autoconfiguration adapter Redundancy mechanisms such as Rapid Spanning Tree and HIPER-Ring Access control according to IEEE 802.1X Port-based security Flow control with prioritisation and traffic shaping Fast "plug & play" commissioning Redundant power supply for high availability Metal housing LED display for device and network status External signaling of alarms via signal contact Compatible with PROFINET, EtherNet/IP, Modbus/TCP etc
