OPC UA Server Plug-in

You can set the following properties in the OPC server configuration:

Server Properties

Property	Description
Name	Any name under which this connection appears in the connection project. Choose a name that is clearly recognizable to you!
Port	Select the port through which the OPC UA server is to be accessed.
HTTPS port	If you activate the first check box, an HTTPS address is added to the endpoint address, the port for which can be specified in the input field. If you activate the second check box, the HTTP address added in the Endpoint Address section is changed to the endpoint of Web Management. Note: If you use this feature with Siemens Industrial Edge, the address without /opcrouter must be specified for clients in order for the connection to work. If the address in the plug-in is displayed as https://172.20.10.220/opcrouter/services/UA/UA-Server, https://172.20.10.220/services/UA/UA-Server would have to be specified in the client.
Sample Rate (ms)	Specify the sample rate of the OPC UA server in ms. After this time has elapsed, the values for the output data points are updated.
Server Certificate	Select the server certificate. You can create a new certificate using the + sign. The certificates are managed via the OPC Router settings.
Accepted client certificates	Specify which client certificates are allowed. You can create and allow additional certificates via the central certificate management in the OPC Router settings. Alternatively, you can use the Windows certificate management.
Login	Specify whether anonymous clients can log in to the OPC UA server. (Restricted security when active)
Endpoint address	The OPC UA server will be accessible via the link displayed.

Security settings

Setting	Description
None	Unencrypted connections are allowed.
Basic128 Rsa15	Only connections encrypted with Basic128RSA15 are allowed. Using the drop-down field, you can define whether a signed certificate is sufficient or whether it must also be encrypted.
Basic256 Sha256	Only connections encrypted with Basic256 are allowed. Using the drop-down field, you can also define whether a signed certificate is sufficient or whether it must also be encrypted.

Data provision

Data	Description
Global variables	If activated, the variables of the OPC router are output as data points.
Performance data	If activated, some performance data of the OPC router service is output.

Address space:

Here you can define the data points for your OPC UA server.

In the "Name" column, you can define a free name for your data point, folder, or object.

In addition, you can define a default value for data points.

User management

User management allows you to define different users with different permissions, such as "Read values" or "Write values."

Property	Description
Interval for address space update	Specifies the interval at which the address space is updated.
Max Session Count	Limits the maximum number of sessions to the specified value.
Max Subscription Count	Limits the maximum number of subscriptions to the specified value.
Maximum string length	Limits the maximum string length (number of characters) to the specified value.
Max byte string length	Limits the maximum number of bytes that a byte sequence can contain to the specified value.
