We developed an OPC-UA server for internal use. Our goal is to communicate with this OPC-UA server using an OPC-UA Client adapter of Siemens Opcenter Connect MOM. During tests with MOM we discovered that when we try to call the OPC-UA method we get the following exception "Method Call Exception: The DataType does not have a DefaultBinary Encoding.".

To validate if our OPC-UA server is compliant with the OPC-UA standard I started testing with the 'UACTT Lite' test tool. However as soon as I try to execute a method call test script I get the error CallService does not exist. After some digging I discovered that I do not have the Call.js file which should be in the following location according to the documentation which is included with the 'UACTT Lite' test tool:

Location: /project>/library/Base/ServiceBased/MethodServiceSet/Call.js

So now I'm wondering is it even possible to test an OPC-UA method call with UACTT Lite or is this only supported in the full version?

Any help is appreciated.

Erik
