11.0 The @aGlance/IT Server Interface
11.1 Introduction
The @aGlance/IT server interface is an optional utility which provides a live data link between the Micro-
PWC and a variety of software applications resident on other distributed control systems, supervisory con-
trol systems, personal computers, and so on. Easy access to this plant data assists those involved in prob-
lem analysis and resolution, product improvement, process improvement and resource optimization.
Obtaining process data directly from the process control system eliminates the possibility of error intro-
duced by manual data entry. @aGlance/IT provides a clean, standardized interface which allows data to
be transferred between different hardware platforms while retaining its meaning, despite inherent differ-
ences in the way data is formatted on different systems (e.g., byte order, floating point formatting, and so
on).
Tools into which you may to import live process data include a broad range of applications, such as rela-
tional databases, expert systems, spreadsheets, simulation tools, report generators, visualization tools,
statistical analysis packages, planning tools, charting tools and graphic tools. Each class of tools( e.g.,
spreadsheets, statistical packages, and so on) has a different way of interacting with users.
In order for the exchange of data to take place, @aGlance/IT is required for each participating network
partner.
The architecture of the @aGlance/IT software is based on a client/server model. A process known as an
@aGlance/IT server typically runs on the system which “owns” the process control data (e.g., a Micro-
PWC). A process known as an @aGlance/IT client typically runs on the system which will be a “consumer”
of that data (e.g., a Micro-PWC, a PC, or a supervisory control computer). A system can run both client and
server applications simultaneously. Client software must be provided by the user.
