Tag Database and Browsing Options
All OPC Browsing Methods Supported
All MatrikonOPC Servers support the following OPC Browse interfaces:
OPC DA 1.0a – IOPCBrowseServerAddressSpace
OPC DA 2.0 - IOPCBrowseServerAddressSpace
OPC DA 2.05 – IOPCBrowseServerAddressSpace
OPC DA 3.0 - IOPCBrowse
OPC HDA 1.2 - IOPCHDA_Browser
OPC A&E 1.02 – IOPCEventAreaBrowser
OPC A&E 1.10 – IOPCEventAreaBrowser
All MatrikonOPC Servers support both the OPC Hierarchical and Flat browsing formats.
Servers can also be configured to force a flat browse structure if required by the client application.
Automatic Tag List Generation
Although every MatrikonOPC Server supports the OPC Browsing interfaces,
the underlying device or protocol dictates what tag information can be auto discovered, and when this
action can occur. All MatrikonOPC Servers will auto generate the tag list or item database for any device
or protocol that provides this feature. All tags or OPC items that are available for access in the underlying
system are automatically exposed to the OPC client application via the Browse interfaces, with no configuration
required by the user. Depending of the specific device, MatrikonOPC Servers also offer configuration options
as to when the tag generation occurs, including:
Automatically on Start-up
Dynamically build ‘on-the-fly’ during run time
CSV File Import/Export
All MatrikonOPC Servers support the ability to generate the tag list or item
database by importing a standard comma separated variable or CSV file. This file can be created using
whatever application the user chooses, including Microsoft Excel, Microsoft Word, NotePad, TextPad, etc.
All MatrikonOPC Servers support the ability to export the tag list to a CSV file.
XML File Import/Export
All MatrikonOPC Servers store their configuration files, including the tag database
information as a standard XML document (eXtensible Markup Language). All MatrikonOPC Servers support the ability
to save configuration information using the XML format. The XML based configuration files can be set to
automatically load on start-up, or on demand.
Import Third-Party Configuration Files
Some devices or systems require the user to pre-configure the
tag list or address space using vendor supplied applications. In many cases, the MatrikonOPC server can
directly import these files. In cases where the MatrikonOPC Server does not support the native interface,
any third party ASCII or Text based configuration file can be automatically imported after it has been
converted to the previously mentioned CSV or XML file formats.
