9. Shorten the filename to match SINUMERIK Operate requirements and make

Verify certificate is in trusted folder:
10. Then the connection to the server can be established from the OPC UA client.
3.5 Testing the connection
Requirement
To test the connection, you can use the "Sample Applications" of the OPC Foundation (
https://
opcfoundation.org/developer-tools/specifications-unified-architecture/opc-unified-
architecture-for-cnc-systems/) under "Developer Tools/Developer Kits/Unified Architecture". It
is necessary to register with the OPC Foundation for this.
Note
There are two ways to establish the connection:
● Connection without security
● Connection with the security policy "Basic128Rsa15" respectively "Basic256" and the
security mode "SignAndEncrypt"
SIEMENS always recommends setting up a connection with security, as only in this way the
confidentiality of the data transmitted can be ensured.
