Installation
ControlNet and EtherNet/IP Connections
Two BNC (Bayonet Neill-Concelman) connectors on the base of the
1788-CN2PAR linking device provide connections for single or dual
ControlNet media. The dual port EtherNet/IP switch provides connections for
multiple EtherNet/IP 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.
The ControlNet connections are described here.
Shielding
Ground the linking device shield connection to a clean earth connection.
Connect the shield to the PA 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 PA media shield to the field device. Tape the media shield back
to avoid accidental contact with other conductors or ground.
