Network topologies
HarshIO
EtherNET/IP modules can be used with a protocol compliant controller as part of control system
architecture. The built-in unmanaged 2-port Ethernet switch allows flexibility in the network topology to meet
your application needs. These topologies include the following:
•
Star
•
Daisy-chain
•
Ring (using DLR protocol)
•
Combination of all above
Star topology
Star topology allows you to connect mixed I/O modules or additional equipment. This topology allows
maintenance on one module
– for example, by removing the network cable, or by power cycling to the module
– without affecting the other modules.
HMI
Ethernet
Switch
PLC
Daisy-chain topology
The daisy-chain topology allows you to connect I/O modules or additional equipment in one line, from one
device to the next in an optimized way along the production line.
When considering the daisy chain topology, note that
•
If a module, somewhere in the middle of the chain, has the network cable disconnected or power to the
module is removed then communications to any module located down the chain will be lost.
•
The embedded dual port Ethernet switch located in each module eliminates the need for additional
Ethernet switches.
