Overview

Telecontrol SCADA is supervisory control and data acquisition software for collecting field data, presenting it to operators, issuing control commands, archiving telemetry, and displaying historical information.

The system uses a client-server architecture. The Server is a set of separate processes: protocol processes (MODBUS, IEC 60870-5-104, IEC 61850 and others), the archive, the configuration, the file store, and a proxy that Clients connect to. The processes are purchased separately and the license lists the ones purchased; a small site needs only one protocol process. See Server processes. Any number of Clients can connect over TCP/IP, and client sessions remain resilient while the Server stays online.

For operation, the system requires one computer for a single-machine deployment or multiple computers for a distributed deployment. The Server processes run on Windows 10 or newer or on Linux; the Client runs on Windows 10 or newer. The Client displays Modus diagrams itself; no additional component is needed for that. The Modus graphical editor is used to edit diagrams.

Installation is described in Getting started, and what changed between versions in the Change log.

All schematics are stored as vector graphics, so even large process diagrams remain compact and can be displayed at large scale on shared operator panels without loss of image quality.

The platform supports one or more operator workstations depending on the required user roles and access rights for the monitored automation system.
