When Tom Burke walks to the podium to give a talk at a conference or even when he first gets on the telephone for an interview, some of the words that usually spill out within the first few sentences are OPC UA and security.
“The vision of OPC is to provide the best specifications, technology, certification and process in support of our suppliers developing best-of-breed products and services that consistently exceed the expectations of the end-users for multivendor multiplatform secure reliable interoperability,” says Burke, the executive director and president of the OPC Foundation in describing the OPC Unified Architecture (UA). “OPC UA was designed to meet the industry requirements of cross-platform, scalable, and enterprise-level data modeling. The OPC Foundation’s UA standard provides the next generation architecture for truly secure interoperability.”
This standard allows developers and users to move away from COM in favor of cross-platform capable Web Services and SOA (Service Oriented Architecture). OPC UA also opens up OPC to non-Microsoft platforms, unifies the OPC data models (DA, A&E, HDA) into a single set of services and it allows for information model extensions to extend OPC beyond its typical markets into the enterprise and down to the devices. All of these features further enhance the requirements related to security.
