Klinkmann Automation Omron Ethernet DAServer 66
Omron Ethernet DAServer Ver 1.x User Manual Rev 1.4 17014m14
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.
Plug-ins
Plug-ins provide a protocol-translation function for device integration clients. Typical Plug-
ins communicate in DDE, SuiteLink, or OPC protocol, and serve as interfaces between
their clients and the DAS Engine.
Note: Items of an array are not supported in the DDE/SL plug-in. These arrays are
converted to HEX strings, which provide legacy behavior for DAServers that support this
in the DAServer-specific code.
DAS Engine
The DAS Engine is a middleware component that exposes two sets of unique interfaces,
one for communicating with the Plug-ins and the other one for communicating with the
PLC Protocol Layer components.
