[milo-dev] OPC-UA server implementation clarification

[Isuru Samaraweera <isuru@xxxxxxxx>]

Hi All,

Can somebody please clarify the below?

• OPC spec says it should support TCP/(SOAP,HTTP)/HTTPS protocols.Which protocols are mandatory to support and which one's are optional?
• If a OPC server is written in Java and TCP can it be accessed by a C# client and vice versa?
• Does different Java Server implementations need unique Java client implementations each? or one Java client implementation can be used to connect with various type of Java server implementations by different vendors?
• If above is yes then there has to be common language like WSDL?Is it?

Please clarify the above

Thanks

Isuru
