The VID (Virtual Instrument Desktop) SCADA HMI software allows very low cost industry standard Modbus, Velleman K8055 or NetCommander hardware to be used in
distributed control and monitoring systems. The Software combines a customizable virtual instrument display with event monitoring, logging, alerting and control systems, to provide a full and customizable HMI to your application.

The virtual instrument panel can comprise a variety of meters, dials, digital displays, graph plotters, thermometers, LED indicators,
control knobs, sliders, buttons and switches. These can be "connected" to a Netcommander monitoring point anywhere on the local
or World Wide network allowing data sources, temperature, pressure, voltages etc. to be visualised in seconds.

The instruments are viewed in multiple virtual screens; the current screen can be selected by using the toolbar forward, backward,
and page cycle buttons or from the drop down list of configured pages.

The system is equally "at home" with a local LAN or RS232/RS485 connected system or a globally distributed system using the Internet
or Corporate VPN.

Each NetCommander monitoring unit can provide up to 16 analogue input and outputs, 16 switch (relay) control outputs and inputs, .
The VID software will control up to fifty monitoring units.
Logs can be maintained and analysed for trends and compared week on week. Control schedules can also be set up.

The events system provides a configurable cause and effect system, several "causes" can be combined using AND/OR/NOT logic to
produce an event that can have several "effects". An "effect" can be a control output, raise an alarm, make a log entry send an e-mail or
SMS, run a control script etc. An almost unlimited number of events can be processed by the VID software, and a more limited number
can be processed by the NetCommander nodes natively, this will allow some basic control to be maintained autonomously,
in the event of network or PC failure.
