11.3.2 Communicating via On Board Ethernet Port
From the factory, the I3N i3 is set to the IP Address 192.168.254.128. To obtain Ethernet
communications between I3 configurator and the I3N I3 using a single Ethernet cable between a
PC and the I3N, or through an unmanaged Ethernet Switch, the PC will also need to be manually
configured as follows (may require Administrator access on PC):
1.
Access the Network Connections in the Control Panel (Shortcut: Press the Windows key
and type ‘Network Connections’… select the resulting filtered link).
2.
Double-click the connection being used to directly connect to the I3N to bring up the
Connection Status.
3.
Click
Properties.
4.
Double-click
Internet Protocol Version 4 (TCP/IPv4)
in the list of available protocols.
5.
The PC may normally be set to “Obtain an IP address automatically”. Click next to
Use the
following IP address:
6.
Use the IP address 192.168.254.111 or something other than that of the I3N.
7.
The Subnet Mask (255.255.255.0) should fill in automatically once the IP address has been
entered.
8.
The Default Gateway is not required for a direct connection.
9.
Click OK all the way back to the Network Connections dialog.
10.
Confirm the I3N is set to the default 192.168.254.128 address or something on the same
network.
11.
In i3 configurator, click
Tools
Application Settings
Communications
Configure.
12.
Select Ethernet, and then enter the IP address of the I3N.
NOTE:
The MTU setting defaults to the maximum 1500. It needs to match the PC’s MTU setting
for the best results. A PC may be set to an MTU of 1300 or something other than the default
maximum setting by a network administrator.
13.
The
Port
for iCAN over Ethernet is
18501
.
14.
The
Mode
for any controller with built-in Ethernet is
Built-in/ETN Ethernet Mode
.
15.
Change the
Timeout
value to
3000
for direct connections. Timeout values of 5000-30000+
may be common for access over the internet or via VPN or other more complex networks.
16.
Click
OK
all the way back to the main i3 configurator window. It may take a moment to
initialize the communications.
17.
Check the status bar for successful communications.
See the next page for examples of the PC Ethernet setup and the I3 configurator Ethernet setup mentioned
in the above steps.
