PQSCADA Analysis Software & Specifications:
Comprehensive Web Serverfor Remote Monitoring
The integral web server allows comprehensive monitoring and control of the unit, with 3-level user privileges and 128-bit SSL cryptographic protocol. It includes tabular display screens, graphical display and remote control and configuration screens. By using an existing web browser, the inconvenience of installing dedicated software is avoided. Most operations can be performed via the web server interface; the screens are intuitive and easy to use. This means that monitoring, managing and analyzing network data can be performed using the web interface.

PQSCADA Power Quality Management Software (Enterprise Edition)
Innovative PQSCADA enterprise analysis software enables operators to view, control, analyze and monitor multiple measurements devices simultaneously. Data is accurately time-synchronized within sites and across sites.

The practically unlimited amount of data, collected from the M4400 devices, is processed and analyzed by using the PQSCADA software. The operator receives a comprehensive picture of graphical system trends and time synchronized power quality values from multiple devices on same screen for statusand anomaly source-propagation analysis.

The software's distributed architecture is scalable and allows easy management of countless local and remote measurement devices. The scalability scheme supports physical expansions and reflects the hierarchy of the components in the electrical grid.

The architecture is built on nodes, sites and enterprises:

Nodes are software components that directly control measurement devices for collection, storage, management and ultimate analysis of measurement data.

Nodes are grouped logically under sites which serve as entry points for various applications (internal and 3rd party) and provide a real-time picture of all connected points for management and configuration functions. Enterprises is the umbrella site that comprises all sites provides all-inclusive
snapshots of the network (trends and data).
