The OPC Controls Data component is used to read and write values to OPC Systems Tag Parameters.
Reading and writing to both local and remote OPC Systems Service Tags simplifies the task of reading and writing OPC data and all of the connection handling to OPC Servers is performed by the OPC Systems Service just as it does with all features of OPC Systems.NET.
If a Tag Parameter Source is defined to an OPC Item when the Tag Parameter is written to the OPC Item is also written to with the same value.
