.NET Realtime Data Access

Programmatic Interface 451

The OPCSystemsDataConnector, OPCControls.OPCControlData component, and OPCWPFDasbhoard.OPCWPFData all can be used to read and write local and remote data of the Open Automation Software realtime database tags including data sources of direct drivers to Modbus, Allen Bradley, Siemens, OPC UA Servers, Classic OPC Servers, OPTO-22, MQTT, AWS IoT, Azure IoT Data Hub, Microsoft Excel, data from SQL Server, Oracle, Access, mySQL, MongoDB, REST API, and other .NET applications.

It is also a very powerful method to make any data from a .NET application become a realtime source for the Open Automation Software platform. This is easily done with the WriteTags method which you can optionally specify TimeStamps.
