Connecting any PLC device to Ignition is easy with OPC UA. OPC UA is the leading industrial standard for platform and vendor-neutral data access. Therefore, a new specification was developed that used common networking principals (like TCP/IP) instead of DCOM, was platform independent, and combined the various separate specifications into one: Open Process Connectivity Unified Architecture (OPC UA). There were several separate specifications that provided functions such as Data Access (OPC-DA), Alarms and Events (A&E), and Historical data (HDA).ĭCOM always proved difficult to work with, and by 2004 it was clear that a more modern solution was needed. The original OPC specifications used Microsoft Distributed Component Object Model ( DCOM) technology to provide a uniform way for industrial applications to share data. Information is exchanged between items such as programmable logic controllers (PLCs), gauges, and databases. OPC is published and maintained by the OPC Foundation, an organization comprised of hundreds of member companies that strives to ensure interoperability on the plant floor and beyond. Open Process Connectivity ( OPC) is a technology standard used to exchange information between hardware and software through specialized drivers.
