OPC UA Compliance Test Tool (UACTT)

OPC UA Compliance Test Tool (UACTT)

The CTT can be used to test OPC UA Client and Server products for compliance to the OPC UA specification.

Multiple versions of the CTT are maintained in order to ensure that products developed against earlier versions of the OPC UA specification can continue to be tested for compliance to those specification versions and associated profiles.
