Using and Selecting an Ethernet switch

Depending on the network size and requested package interval (RPI) a suitable switch
must be used. Also if multiple separated networks needs to be connected a switch is
used.
Depending on the actual size of the network different requirements needs to be meet.
Generally using EtherNet/IP with a fair package interval a 1 Gbps switch is typical ade-
quate along with the following features:
• Auto negotiation, full duplex 100 MBit
• Port mirroring for network analysing and troubleshooting purposes. This feature
makes it possible to route traffic out on a separate port connected to a network
analyser for debugging purposes and general performance monitoring.
The JVL EthernerNetIP module has a small build in 2 port switch useful if a small amount
of motors is connected in a daisy chaining topology.
The disadvantage of this approach is that the package RPI timing is reduced as each motor
needs to handle the incoming traffic for the other motors connected on the line.
