Modbus parameters
8.4.2
EtherNet/IP via Ethernet
You do not need to make any settings for the EtherNet/IP protocol.
8.4.3
HART via Ethernet or RS-485
The parameters contained in this leaf pertain to the set up of the HART communication to
the host on the interfaces offered by Fieldgate SWG70.
1. Click
Wired Communication => Protocols => HART
to display the associated
parameters:
2. If the default port number is changed, and FieldCare is in use, communication will be
lost.
3. Reconfigure the HART IP CommDTM communication parameters, before making
connection again. See Chapter 7.3.2 "Adding the Fieldgate SWG70" on page 38, Step 4.
