A unique low cost run-time key can be used to run any of the
applications, independently of the number of tags involved.
Multilanguage applications (in two languages or more) can be set up,
with a simple command to switch between languages. Reports and
historical data can be recorded in a format that can be accessed
directly from other software packages (Excel, Access, etc.).
Distributed Client/Server architectures can be set up using a TCP/IP
protocol and a Intranet/Internet network. Multi-master structures,
in which each terminal can communicate with the others so as to
allow both reading and writing, are also possible. Both the fix and
mobile (GSM) telephone network can be used to communicate with remote
devices or to send SMS to maintenance operators; in this way a
supervision centre can provide a remote assistance service to a
network of peripheral sites spread around the country.
Historical or online trends can be displayed individually or in
groups: up to ten trends at a time are possible, which can refer to
different kinds of tags, each with its own colour and scale. The
temporal axis can be shifted backwards and forwards using video icons,
the mouse can be used to zoom in and out, and various other viewing
options are possible (grids, line thicknesses, modes of
EVENTS AND ALARMS
Events and alarms can be activated as a function of the values taken
on by associated tags: alarms are signalled immediately in a specially
reserved area of the screen, and the confirmation by the operator is
also controlled. Status information (active events) and history
(date, time, event) can be accessed according to various freely
definable categories (eg. priority and location).
The recipes are sets of characteristic values of a working process or
a plant configuration: new recipes can be created and existing ones
updated (copied, deleted, renamed, printed and modified), as well as
being imported and exported to and from the process itself. The
application of a recipe can be commanded by the operator,
automatically executed on start-up, or triggered by the program
(eg. batch process).
Reports with summary information about production data or process
quality or plant alarms can be generated in a pre-programmed format
and can be displayed or printed or sent to any peripheral device.
Reports can be either requested by the operator, or automatically
generated on a cyclic basis (after a specific time interval, on a
particular day of the week, etc.), or triggered by the program
(eg. in case of end of production ). Copies of reports are also
recorded in history files and can be accessed by other software
packages (Excel, Access, etc.).
Each menu item, template, tag, etc., can be protected by the
specification of the groups authorized to access it and those who
can modify it. A name, password, and member-ship of one or more
groups can then be defined for an unlimited number of operators.
Every operator's action that has produced a data modification is
recorded in a history file by date, time, event description and
