UA Discovery dialog box
Use this dialog to find the discovery server, which publishes a list of OPC UA servers on the network, and
then select the server to which you want to connect.
4. In the User Name and Password boxes, type your login credentials for the OPC UA server.
5. If the OPC UA server is configured to require a secure connection, then you must take the extra steps
of installing the server certificate in your project and generating a client certificate to be installed on the
server:
a. Get the server certificate and then save it in the Config sub-folder of your project folder (e.g.,
[…]\Documents\InduSoft Web Studio v7.1 Projects\projectname\Config\). The method for
getting the server certificate depends on the server, so please consult the server vendor.
b. In the UA Server Configuration dialog, click Security. The OPC UA Security dialog is displayed.
c. In the Server Certificate list, select the server certificate. (All certificates saved in the Config sub-folder
should be listed here.)
d. In the Security Policy and Message Security Mode lists, select the appropriate options for how the OPC UA
server is configured. Again, please consult the server vendor.
e. Click Generate Certificate. The client certificate is generated and saved in the Config sub-folder.
f. Click OK to close the OPC UA Security dialog.
g. Install the client certificate on the OPC UA server. The method for doing this depends on the server, so
again, please consult the server vendor.
For more information, download the white paper "The OPC UA Security Model for Administrators" from the
OPC Foundation.
6. Click OK. The connection is saved in the OPC UA Connections folder in the Project Explorer.
