Unmanaged switches
Unmanaged switches allow a cost-effective entry into Industrial Ethernet
engineering. They require no conguration, since they function using plug-and-
play.
Use
• In price-sensitive applications
• If they are designed as compact plug-and-play modules
• To allow simple installation of Industrial Ethernet
networks
• Do not have to be congured or given parameters.
When you use unmanaged switches with EtherNet/IP in networks
with realtime I/O trafc, you have to understand that the multicast
messages for certain address circles will be sent unltered to all
ports with this type of switch (per broadcast), which increases the
network load.
