TOP Server OPC DA Client Driver Details
Reliable Data Aggregation and Tunneling Solution
The TOP Server OPC DA Client Driver enables standard, reliable connectivity to local or remote 3rd party OPC DA Servers. The OPC DA Client Driver can aggregate information collected from multiple OPC DA servers, giving your client applications a single point-of-access for all of your process data
Once available in TOP Server, data from OPC DA Servers can be shared using TOP Server’s standard, built-in OPC UA, OPC DA, DDE or native interfaces such as Wonderware SuiteLink and Fix NIO/PDB, providing gateway connectivity for non-OPC DA clients.
Use the OPC DA Client driver as a bridge to move your client technology forward to the latest OPC standard, OPC UA. Give OPC UA clients access to your existing OPC DA Server applications now without having to wait for those OPC DA Servers to have an OPC UA interface. Additionally, when combined with the OPC UA Client driver in the OPC Client Suite on a remote client machine, you can tunnel OPC DA data to remote client applications without DCOM.
