OPC Server DA
OPC Server DA (data access) communication and data exchange software
OPC Data Access (DA) is a set of standards that provides specifications for real-time data communication from data acquisition devices such as display PLCs and human machine interfaces (SCADA/HMI). With the standard OPC DA interface, experience in manufacturer-specific protocols is not required. This allows a significant reduction of the development, commissioning and maintenance burden. The OPC DA specifications are based on Microsoft COM technology and define a C/C++ interface.
