SuiteLink is not a replacement for DDE, FastDDE, or NetDDE. The protocol used between a client and a server depends on your network connections and configurations. SuiteLink provides the following features:
•Value Time Quality (VTQ) places a time stamp and quality indicator on all data values delivered to
•Extensive diagnostics of the data throughput, server loading, computer resource consumption, and network transport are made accessible through the operating system’s performance monitor. This feature is critical for the operation and maintenance of distributed industrial networks.
•Consistent high data volumes can be maintained between applications regardless if the applications are on a single node or distributed over a large node count.
•The network transport protocol is TCP/IP using Microsoft’s standard WinSock interface.
