OPC Scada Viewer

OPC Scada Viewer is a tool designed to extract information from OPC (OLE for Process Control) servers. Subsequently, OPC provides a client/server interface between Windows applications and industrial hardware devices.

Setting up the program is a simple task that requires minimal attention on your behalf. By default, OPC core components redistributable files and a demo are included in setup but you can exclude any of them if you're not interested.

OPC Scada Viewer's interface is represented by the main app window that shows a graphical representation of the OPC server, along with a simulator window which reveals real-time readings of the monitoring system.

The monitoring system is shown using a picture, and new tabs can be added with any relevant images from the computer. You can also create blocks with server connections, representing indicators, borders, captions, states, windows, values, minimum, maximum, scale, or scripts.

The simulator window displays the current value of each item from the monitoring system, together with the data type, whether or not the object is null, quality, and simulation nodes. Updates can be made with one click for any item, and you can also change the default update interval. Requested items can be added to this area automatically, depending on your preference. Visual and audio warnings are triggered when an OPC tag exceeds the limit you specify.

The OPC configuration details can be saved to XML files or to the registry. It's possible to switch to fullscreen mode, forbid configuration changes and modifications in block positions and sizes, password-protect the program, as well as customize UI colors for information, warnings, errors, and others.

OPC Scada Viewer makes it possible to write custom values to OPC servers, like rotating switchers for Bool values. It worked smoothly on Windows 10 throughout our evaluation. Taking into account its user-friendly interface and options, the program delivers a straightforward solution for recovering data from multiple OPC servers at the same time.
