SCADA

Asix is a platform for HMI/SCADA/MES systems developed by ASKOM since 1994. It is designed for creating and implementing industrial IT systems for enterprises, processes, production lines, machines, and devices.

The primary use of Asix is SCADA applications – for operator stations to directly supervise and control processes. It enables data acquisition from programmable controllers, meters, and other measurement devices. Commands such as starting and stopping drives are sent to controllers, analog and binary data trends are recorded, and an alarm log is maintained. Using Asix, HMI-class applications for operator panels can also be created. The platform supports online production tracking, calculating performance and quality indicators, data analysis, and reporting to ERP systems.

The Asix platform offers a wide range of features, making it ideal for various industries. Key features include:

The Asix platform allows using a single SCADA application, but the available information and possible actions depend on the user's location and access rights.

The application's wide range of tools and functions, combined with a precise permission control system, allows for:

The Asix platform is a robust solution for various industries, from standard supervision and control applications to advanced monitoring systems. This is confirmed by over 16,000 licenses sold, used in the following sectors:

Current measurement values can be displayed numerically or using graphical objects representing analog readings. Measurement panels, which are small windows providing concise information about the current measurement state, technological limits (modifiable), and a trend graph, are commonly used in applications. Binary signals are used to reflect the status of devices and control them, such as information on drives, activation states, electrical readiness, and limit switch breaches.

Data archiving is performed by the Aspad historian module, which efficiently collects analog and binary data trends. The capacity of the online archive available on the operator's or dispatcher’s computer is limited only by the disk size, allowing for years of historical data storage. In version 9, the historian was enhanced to process and record current data with a precision of 100 nanoseconds.

Data can be archived in the internal Aspad module format, ensuring real-time data compression and redundancy removal, or in an MS SQL database. Data is saved in UTC, providing consistent timestamps regardless of daylight saving changes or different time zones.

Archived data is made available as raw data or aggregates for other Asix platform modules and third-party software.

The AsTrend program is a tool for in-depth analysis of historical data. It displays, reviews, and prints time trends of selected variables, creating “graphical reports” of system performance. AsTrend can operate as part of the visualization system or as a standalone program, even in a web browser, with local or remote access to the data archive.

Standard Asix licenses allow continuous data archiving with a resolution of up to 100ms. For higher frequency data collection, the AsLogger module is available, which records short-term data series in an SQL database. Fast series mode is supported by selected electrical protection drivers.

Data from the Aspad module is used to create measurement charts directly on process diagrams. Operators can adjust the charts by changing the visible time horizon, scrolling through history, zooming in, or reading specific past values.

Modern SCADA systems are expected to provide advanced reports for management, synthesizing data from multiple applications and enriching it with statistical analysis. Asix meets these requirements by offering:

User authentication and access control in Asix are based on user roles, defining detailed permissions. Actions are only executed if the user has appropriate permissions.

AsAlert ensures reliable and fast notification of abnormal system states or failures via:

The Asix Mobile module extends the platform’s tools to mobile devices, enabling visualization and control interfaces tailored for small screens and touch operations.

The Evo technology design environment provides a user-friendly interface for configuring visualization systems and applications.

Asix applications can be published on local networks or the Internet, accessible through web browsers without functionality limitations.

Asix supports “hot redundancy” configurations, ensuring system stability and minimizing the impact of hardware failures.
