Example 2
0 Eth 192.168.1.65 Slot 1 CLX
This path in this routing definition is the same as the previous example, but now the Link ID is 0.
Local messages sent on Data Highway Plus to the AN-X station address (37) will by default use
this path.
Example 3
15 Eth 192.168.1.57 PLC
The routing definition uses link ID 15. It routes messages from the AN-X across Ethernet to an
Ethernet/IP enabled PLC-5 at IP address 192.168.1.57.
Remote messages sent on Data Highway Plus using link ID 15 will use this path.
Example 4
16 PlcCsp 192.168.1.58
The routing definition uses link ID 16. It routes messages from the AN-X across Ethernet to an
older Ethernet PLC-5 that doesn’t support Ethernet/IP, at IP address 192.168.1.58. It uses the
older CSP Ethernet protocol.
Remote messages sent on Data Highway Plus using link ID 16 will use this path.
Example 5
2 Eth 192.168.1.65 Port 1 1 CLX
This routing definition uses link ID 2. The path is the same as in example 1, but instead of the
Slot keyword, it uses Port, with parameters 1 1 (backplane and slot number).
It routes messages from the AN-X across Ethernet to IP address 192.168.1.65 (a 1756-ENBT),
then across the backplane to slot 1, which contains a ControlLogix processor.
Remote messages sent on Data Highway Plus using link ID 2 will use this path.
Refer to Ethernet/IP documentation for detailed information on possible port values.
Example 6
122 Eth 192.168.1.14 Slot 1 DHA
This routing definition uses link ID 122.
It shows how to route messages through another AN-X at IP address 192.168.1.14, to a second
Data Highway Plus. AN-X emulates a 4-slot ControlLogix rack with a 1756-ENET in Slot 0 and
a 1756-DHRIO in slot 1. The emulated DHRIO has only channel A since the AN-X has only one
Data Highway Plus network port.
This Link ID must match the Local Link ID of the second AN-X.
The second AN-X must have a routing table entry
121 Eth 192.168.1.12 Slot 1 DHA
to return replies to the original AN-X, which has local link ID 121.
