OPC UA

OPC UA is a standardised communication protocol for the secure exchange of data between machines, controllers and IT systems. In industrial environments, OPC UA is used as an interface to provide information in a structured and vendor-independent way. It can also be used for M2M communication between machines when data and statuses need to be exchanged directly and consistently. For RFID and auto-ID applications, this is important when captured data needs to be transferred into data integration without media discontinuity. Data and statuses are described in a uniform way so that equipment, identification technology and software can communicate cleanly with one another. Standardised communication supports the reliable transfer of captured and process data between the shop floor and IT systems.
