SMD17E2 User Manual
INSTALLING THE SMD17E2
93
1.8 EtherNet/IP Connections
1.8.1 Non-DLR Applications
The SMD17E2 units have two Ethernet ports with a built-in Ethernet switch connecting the two. In non-DLR
applications, either port can be used to attach the unit to the network. The remaining port can be used to
extend the network to another device if this would reduce wiring costs.
1.8.2 DLR Applications
In Device Level Ring applications, the SMD17E2 units function as Beacon-Based Ring Nodes. In these
applications, both ports are used when wiring the ring, daisy chaining from one unit in the ring to the next.
1.9 Modbus TCP Connections
The SMD17E2 units have two Ethernet ports with a built-in Ethernet switch connecting the two. Either port
can be used to attach the unit to the network. The remaining port can be used to extend the network to another
device if this would reduce wiring costs.
1.10 PROFINET Connections
1.10.1 Non-MRP Applications
The SMD17E2 units have two Ethernet ports with a built-in Ethernet switch connecting the two. In non-MRP
applications, either port can be used to attach the unit to the network. The remaining port can be used to
extend the network to another device if this would reduce wiring costs.
1.10.2 MRP Applications
In Media Redundancy Protocol applications, the SMD17E2 units function as a Media Redundancy Client
(MRC). In these applications, both ports are used when wiring the ring, daisy chaining from one unit in the
ring to the next.
