Installation
ControlNet and EtherNet/IP Connections
Two BNC connectors on the base of the 1788-CN2FFR linking device provide
connections for single or dual ControlNet media. The 1788-EN2FFR linking
device uses an RJ45 connector to connect to an EtherNet/IP network. The dual
port EtherNet/IP switch on the 1788-EN2FFR linking device provides
connections for multiple Ethernet topologies, including device level ring (DLR).
The EtherNet/IP port can also be used as a connection point in the field to access
the web server or asset management tools.
Shielding
Ground the linking device shield connection to a clean earth connection.
Connect the shield to the H1 media so that connectivity runs through all
junction boxes, but is not connected to the field device shield or grounded at the
device.
Do not attach the H1 media shield to the field device. Tape the media shield back
to avoid accidental contact with other conductors or ground.
