OvOPC Compliance
Compliance Testing is a process which verifies that an OPC product implements a specification properly by using a standard software test tool developed by the OPC Foundation. This test tool, called the Compliance Test Tool or CTT, is currently available for several specifications. Vendors can download the CTT from the OPC Foundation website and run the tests at their site. The company’s administrator or designated product manager for the OPC Foundation WEB site can then attach the encrypted file generated by the CTT to the appropriate OPC Foundation Product catalog item. The OPC Foundation Product Catalog will display the results to the public. OPC Users should look for OPC Server products that have passed the compliance tests for all specifications that the product supports and display the “Self Tested” logo.

Compliance Testing is only available for OPC Server products.
