DAServers

A DAServer is comprised of three physical parts (see the following figure). They are the following:

• Plug-in Component(s): Responsible for communicating with clients.

• DAS Engine: This common component is used by all DAServers.

• PLC Protocol Layer; DAServer-specific: Responsible for communicating with the hardware.

  

  DAServer Architecture

Each physical part of a DAServer is comprised of a set of .exe and/or .dll modules. Wonderware provides the Plug-ins and the DAS Engine. The DAS Toolkit user creates the PLC Protocol Layer (DAServer-specific) modules. All three sets of modules are required for a fully functioning DAServer.
