ETHERNET TCP/IP
Overview
Ethernet parameters can only be configured via the Communication
set up group, or Honeywell EasySet.
Ethernet IP Address is 10.0.0.2 as shipped from the Factory.
The MAC address is printed on the case label of each instrument.
Widely used by manufacturers, the Ethernet connection, which uses
Modbus TCP/IP, allows the controller to connect to other Ethernet
networks and exchange data with computers or devices on that
network for monitoring or managing your process from almost any
location.
When constructing a network, it is recommended that a Switch be
used to connect UDCs to a LAN rather than using a Hub. This is
because a Switch passes only those messages for IP addresses that
are connected to the Switch while a Hub passes all message traffic.
Using a Switch thus improves the overall throughput of the traffic to
and from the UDCs.
To secure the network communication, it is recommended to use IP
security (IPSec) to set up a Virtual Private Network (VPN).
