When creating new connection to OPC UA
server go to Add Connection
expand item UA server
and enter the OPC UA
server path (url address ) into the input field. Then it is necessary to create certificate for the OPC UA Proxy
by pressing the button "Manage certificates
It is possible to use certificate that was created automatically or create user certificate (by pressing the "plus" button in the upper right corner of the screen, enter the desired parameters - validity, company name and confirm changes by pressing the "Create
" button). It is also possible to import user certificate.
The new created certificate is then visible in the certificate list.
Once the certificates are created it is necessary to select the desired connection security level and select the proper certificate for connection validation. After entering all necessary data confirm by the "Create
" button the creation of new connection.
If the certificate was not downloaded or imported from the OPC UA
server, then the OPC UA Proxy
after confirmation downloads, displays and accepts available certificate of the corresponding server and assigns it to the created connection.
In order to use the created connection it must be activated. On the OPC UA
server side it is also necessary to add the OPC UA Proxy
certificate into the list of validated certificates (e.g. by moving it from the list of rejected certificates). This procedures may differ based on the OPC UA
server that is being used.
If both OPC UA
objects (server and proxy) the correct certificates properly set, then in the PROMOTIC application (on the same computer where the OPC UA Proxy
is running) the classic OPC DA
communication with the Matrikon OPC UA Proxy
can be used.
