The PLC Protocol Layer provides a protocol-translation function for specific hardware,
such as OMRON FinsGateway; and it serves as an interface between the DAS Engine
and the hardware.
Component Environments
Stand-alone DAServers have the following characteristics:
• The DAS Engine is dynamically linked to the other DAServer components. In other
words, a new DAS Engine (feature enhancement or bug fix) would not require relinking to
the other components nor re-QA of those other components. When deployed to the
system, the new DAS Engine would attach to all existing DAServer components.
• Newly deployed Plug-ins (feature enhancements or bug fixes) do not require relinking
nor re-QA of associated components. Even new Plug-ins (for example, OPC Alarm &
Events) would not require any development
changes to the other components, and therefore no relinking in a customer-installed
base. In fact, it is feasible to implement new functionality in a Plug-in to enhance the
DAServer without any involvement of the code of
the other components.
• DAServers can be configured in one stand-alone configuration utility (DAServer
Manager), and the DAServer Managerand is capable of displaying specific configuration
views for all DAServers. This utility allows the browsing and editing of DAServers on
different nodes.
• The DAServer Manager diagnostics tool displays generic diagnostic objects common to
all DAServers, in addition to the DAServer-specific/DAServer-developer-defined
diagnostic data. The DAServer data configuration format is XML. Any XML-enabled
program (for example, XML Editor) can read this format.
