| Requirements
for Hardened Ethernet |
| 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 switch products
which are also able to provide redundancy mechanisms such as HIPER-Ring
or network access control according to IEEE 802.1X.

| With
the new OCTOPUS family, the first manageable hardened Ethernet switch
at the field level, Hirschmann offers the optimum solution. The OCTOPUS
family has the necessary processing power to provide extended management
by SNMP, as well as prioritisation and traffic shaping. This means
that Industrial Ethernet with a full feature set can now be used in
previously inaccessible places – without large-scale re-cabling. |
