As such, the server provides access to DDE applications that support one of the following DDE formats.

SuiteLink is a clientserver communication method that has succeeded FastDDE.

Both FastDDE and SuiteLink are supported by all Wonderware client applications.

When supported, this interface also has the ability to refine the connection between the server and the iFIX Process Database (PDB).

It focuses on minimal overhead (2-byte header) and is recommended when bandwidth is limited.

It is a clientserver technology where one application acts as the server (providing data) and another acts as a client (using data).

OPC Data Access is the most prolific and enables data exchange between multi-vendor devices and control applications without proprietary restrictions.

An OPC server can communicate data continuously among PLCs on the shop floor, RTUs in the field, software applications on desktop PCs, and much more.

OPC compliance makes continuous real-time communication possible (even when the hardware and software are from different vendors).

Although it continues to be supported by many of the OPC client applications in use today, OPC Data Access 2.0 Enhanced OPC better utilizes the underlying Microsoft COM technology.

OPC Data Access 3.0 is the latest version of the OPC DA interface.

It defines behaviors for many well-known aggregates, which are methods that summarize data values over a particular time domain at the time of data retrieval.

It can be used to create a simple trend data server and more complex data compression and analysis servers that are capable of providing summary data, history updates, history data annotations, and backfilling.

It offers a secure method for remote client-to-server connectivity without depending on Microsoft COM or DCOM technology, and has the ability to connect securely through firewalls and across the Internet, WAN, or LAN.

Kepwares implementation of the UA server supports optimized binary TCP and the DA data model.

It also enables communications servers to be configured via remote client machines.

ThingWorx services enable users to browse, read, write, and interact with KEPServerEX.
