Bachmann atvise® scada

Visualization strictly using web technology

The implementation of atvise® scada was based strictly on web technology from the very beginning. This means that any end device with a web browser can become a SCADA client, without any installation effort or additional licensing costs. All that is needed for visualization is a web browser.

Vertical communication via OPC UA

A wide range of available OPC UA services allows process data to be distributed flexibly in the overall architecture. OPC UA Data Access, Alarms & Conditions, Historical Access and Methods are available as interfaces for retrieving and providing process data. These interfaces can be used not only for the interaction between atvise® systems, but also by all communication participants that have implemented one of these OPC UA services. Such implemented systems remain continuously synchronized in the overall architecture, all without loss of information or interface adjustments 1) .

1) Provided on all supported platforms.

Completely scalable

Solutions implemented with atvise® scada can be expanded at any time. This means that the same project can be scaled from a small-scale application with a few data points to a distributed large-scale application with several million data points. The full range of functions is always provided on all supported platforms, on both low-end and high-end hardware.

Wide range of data interfaces

Process data from all well-known control manufacturers can be connected via OPC UA (also via connection and user certificates). In addition, atvise® scada offers ready-made interfaces to databases and web services. With the atvise® connect communication module, the data interfaces of atvise® scada can be expanded further and nothing stands in the way of convenient data access to Siemens and Rockwell controllers. Modbus TCP, BACnet, KNX and MQTT are also available as communication interfaces.

Dynamic alarm processing

Many powerful features are offered in the area of alarm processing. Alarms can be structured in arbitrarily nestable alarm hierarchies and enhanced with further process information at runtime. In addition to delayed alarms, alarm management functions such as reset, deactivate, suppress, acknowledge and comment are offered; these can be executed by the operator as well as by the runtime system itself.

High-performance archiving

Process data, alarms and user interactions can be easily and conveniently historised. Large data queries are intelligently divided into small data packet and reloaded piece by piece. For the management of historized data, online archive management is offered, with which data archives can be removed and then restored again at runtime. Fine-grained event archives ensure the transparent structuring of different events in the system.

High-performance scripting engine

With fully parallel processing of server-side scripts, the scripting engine of atvise® scada offers outstanding scalability and performance for industrial data processing. All available process data can be accessed. The manipulation of existing data points and the creation of new data structures is also possible dynamically at runtime. In addition, ready-made functions for processing text files in CSV and XML format are also provided.

Failure safety as a system solution

The Hot-Standby Redundancy of atvise® scada ensures comprehensive fail-safe reliability of the data source connections, the runtime environment itself as well as web clients. The redundancy system is synchronized throughout and a switchover to the operating server takes place without data loss. Even in the event of a fail-over, the process is handled fully automatically by the passive server system within a few seconds.

Powerful project planning

The engineering tool of atvise® scada offers flexible remote access to the project server, which can be used by several team members at the same time. Using online engineering, project updates can be imported at runtime without interrupting processes currently running in the runtime system. Numerous editors are offered for the engineering of data structures, alarms, archive configurations and much more. Furthermore, with an extensive catalog of graphic objects and many prepared visualization layouts with responsive design support, everything that is needed for the fast and efficient implementation of applications is provided.

Fine-grained access control

The access control implementation within atvise® scada enables the efficient realization of simple as well as complex authorization structures at the same time. Authorizations can be defined for sub-trees or individual data points of an atvise® project. These defined authorizations can be extended at any hierarchical level, which means that atvise® scada offers a high degree of design freedom and flexibility in the implementation of authorization systems. With an additional separation option between visualization and engineering users and integrated authorization indications in all atvise® graphic objects, the convenient implementation of authorization systems is easily possible.
