Refers to the Wonderware A2 Supervisory Control Platform, commonly known as the Application Server. The Wonderware Application Server is sized by (a) the number of Workstation / Server Platforms, (b) by real I/O in the system, and (c) the number of Terminal Services sessions. The Application Server license is per Galaxy. An Application Server can be distributed across multiple computers as part of a single Galaxy Namespace. The Wonderware Application Server is designed to leverage existing Wonderware products such as InTouch for visualization, Industrial SQL as its historian, and the device Integration product line (I/O Servers) for device communications. The Wonderware Application Server uses InTouch v8.0 or InTouch View v8.0 for visualization with the addition of Platforms to the visualization node.
