12.7.1.1 Configure OPC tunnel for remote access (Windows® CE)
For the configuration of the OPC tunnel, the oct.xml configuration file must be edited.
In our example, the IP address of the Controller controller is: 192.168.5.99
• For configuring OPC tunnel 1, use the oct.xml configuration file in the \USBStorage\OCT
storage\OCT directory. Enter the corresponding IP address of the control controller in the
configuration file (as described in the following section).
• For configuring OPC tunnel 2, standard settings need not be changed (configuration file:
oct.xml).
Preparation

How to set up an external visualisation on the controller:
1. Go to the \USBStorage\OCT directory.
2. Rename the oct.xml file to oct_save.xml
3. Rename the octvisu.xml file to oct.xml
4. Open the oct.xml file using an editor.
This is a text file. Use the Software Microsoft Editor, for instance, for edition.
5. Go to the following section:
6. Enter the IP address of the controller (with the control function).
7. Line contents (example):
8. Save changed file on the SD card.
9. Restart the controller (with the visualisation function).
The OPC servers of the control controller can now be accessed.

Tip!
To undo faulty changes in the configuration files, the original state of the configuration
files can be restored. For this, delete all configuration files from the \USBStorage\OCT
directory and restart the controller.
