The OPC Foundation offers certification tests to ensure that OPC products (Clients and Servers) meet the defined specification. OPC Foundation members can use the Automated tools to test their OPC products. OPC products that pass the battery of tests can be classified as OPC Compliant and display the OPC Compliance logo. The OPC Foundation (www.opcfoundation.org) is responsible for defining and maintaining the OPC Compliance automated testing harness.
