304 @aGlance/IT Server Interface
11.1.1 The @aGlance/IT API for Micro-DCI
Any @aGlance/IT client can connect to any @aGlance/IT server, assuming the minimum requirements for
network transport are met to access the server running on the Micro-PWC.
The @aGlance/IT Application Programming Interface (API) on a Micro-PWC consists of:
• An @aGlance/IT server which can provide data to @aGlance/IT clients.
• Support for @aGlance/IT methods (functions) used by:
• commercially available @aGlance/IT client applications
(e.g., the @aGlance/IT Add-In for Excel)
• users engaged in creating custom @aGlance/IT client applications
Also provided is a window-based interface for:
• Identifying data structures in the Micro-DCI databases (by tagname and atom).
• Defining translations for the Micro-DCI atoms to other terminologies, such as the Instrument
Society of America’s SP72 standard.
• Viewing information about servers and server activity.
The implementation of @aGlance/IT on Micro-DCI permits the access of up to 500 points per second from
either the client or server side.
11.1.2 Micro-DCI @aGlance/IT Server Requirements - Micro-PWC Version
The following requirements must be met in order to successfully run the @aGlance/IT API server on the
Micro-PWC:
• TCP/IP must be installed on the node on which the @aGlance/IT server is to run.
On the Micro-PWC, if a single channel Ethernet board is present and detected by the
Windows software during installation, the necessary TCP/IP software will be loaded
automatically. If the Ethernet board is not detected, the TCP/IP software should be installed
when it is prompted for during installation of the Windows software.
• A properly installed license for the @aGlance/IT API for Micro-DCI must be present. One
Micro-DCI @aGlance/IT Server Interface license is included with each set of Micro-PWC
software. Additional licenses can be purchased.
On the Micro-PWC, the user is prompted to enter license keys during the initial startup of the
system, as described in the Micro-PWC Installation and Setup Guide. After the initial startup,
installation of license keys is performed using the License Administration menu, described in
the Micro-PWC Installation and Setup Guide.
✎ Note A single client license is installed as standard. A multiple client
license is optionally available.
