13. TCP / IP Communications
EPSON RC+ 5.0 (Ver.5.4) User's Guide Rev.4 281
13.2 TCP/IP Software Configuration
You can configure TCP/IP settings for the RC180 controller in a SPEL
+
program using the
SetNet command. You can also configure settings from the TCP/IP tab on the Setup |
Controller dialog.
To configure a TCP/IP port
1. Select Controller from the Setup Menu and select the page for the TCP/IP port you
want to configure.
2. Enter the IP address for the controller or PC that you want this controller to
communicate with.
The controller does not support DNS, so you must specify an IP address for the host
you are communicating with. You cannot specify a name for the host.
3. Enter the TCP/IP port number. This must be the same port number that is used on the
host device. It must be different from any of the other TCP/IP port numbers used for
the other TCP/IP ports.
4. Change the other settings as desired.
5. Click Apply to save the new settings and click Close.
