Hardware Components; Figure 7 - Controller Rack Components - Honeywell 900U02-0100 User And Installation Manual

Note:
The ControlEdge HC900 is equipped with an Ethernet port as a standard feature (two Ethernet ports on
the C70
& C75 CPU). These ports can function simultaneously as slave and master communications ports.
The dual Ethernet ports (C70 & C75 CPU's) can be configured for redundant operation to a host.
If the host device does not have the inherent capability to recognize a network failover, the
Honeywell HWIOPC Server would be used to perform this functionality.
The dual Ethernet ports will not operate in a redundant configuration through a gateway to a
Host / server on another subnet. While both the E1 & E2 Ethernet can be configured with a default
Gateway address, only the E1 port will communicate across a gateway to another subnet.
