OPC Scada Viewer. This OPC client program retrieves OPC data and displays it in real-time with the help of various indicators    

Brief description:

The family of the OPC software technologies is a unified interface for controlling automation objects and technological processes. Most gauges, monitoring and control devices nowadays have OPC servers that can be used to obtain the current data. OPC Scada Viewer supports the primary and most widely used OPC DA1 and DA2 standards that allow you to exchange data with programmable logic controllers, human-machine interfaces, computer numerical controlled devices, and other devices in real-time.

What problems can be solved with OPC Scada Viewer?

OPC Scada Viewer allows you to easily and very visually display data received via the OPC interface. Data is displayed in real-time, which allows you to use the program for permanent control and monitoring in various systems. OPC Scada Viewer offers many indicators for displaying the values of OPC tags, from simple analog pointer indicators to charts and diagrams. It is possible to customize every indicator separately for your needs.

A good example of using the program is replacing a large and cumbersome SCADA in a system where it is necessary to only control and monitor and where there is no need to send any commands back.
