LAN Port
Connections
NOTE
This only applies to the IPC (industrial PC)
controller.
If you replace the IPC in your system — or the
single-board computer (SBC) in the IPC — and
re-connect the LAN cables to the IPC exactly as they
were before, communication to the testhead or site LAN
could be broken. This is because the mapping of the
LAN configuration to the physical ports in the IPC can
be different from one IPC to the next (due to different
firmware on the SBC).
Simple Solution
In most cases, the solution is simply to swap the LAN
cables on the two LAN ports.
If you do this, and communication still doesn’t work, the
properties of the LAN connections may be set
incorrectly.
Setting the LAN Connection Properties
1 Disconnect one of the LAN cables from the IPC.
Trace the cable so you know whether you are
disconnecting the site LAN or testhead LAN.
2 Look at the network configuration.
For Windows 2000: Click Start > Settings > Network
and Dial-up Connections.
For Windows XP: Click Start > Settings > Control
Panel > Network Connections
You will see two connections:
Local Area Connection
Local Area Connection 2
The one that is disconnected will have a red X or say
unplugged (depending on your View mode). This
tells you which physical port is mapped to which
LAN connection.
3 Check the properties of the connections: Right-click
on a connection and click Properties. The properties
should be set as follows:
4 Re-connect the LAN cables and set the connection
configurations until the communication works
properly. If this still doesn’t work, you may need to
download drivers; see Installing Drivers and
Configuring LAN Ports on page 2-62.
Local Area Connection (site LAN)
Property: Obtain IP address automatically
Local Area Connection 2 (testhead LAN)
Property: Use the following IP address: 10.3.112.3
