SCADAservere

SCADAservere is a term used in some documentation to denote the central software component of a SCADA system. It is not a standard industry term and its exact meaning can vary by vendor or project, but it generally refers to the server-side element that aggregates data from field devices and provides interfaces for operators and applications.

In a typical SCADAservere configuration, field devices such as PLCs and RTUs collect process data and issue control commands. These devices communicate with the SCADAservere over industrial protocols such as Modbus, DNP3, or OPC UA. The SCADA server stores data in a historian database and serves it to human-machine interfaces, reporting tools, and automation subsystems.

Core functions include real-time data acquisition, event and alarm processing, trend visualization, historical data storage, and the ability to issue control commands within authorized permissions. The SCADAservere often integrates with alarm notification systems, analytics modules, and ERP or MES platforms.

Deployment models vary from on-premises installations to cloud-based or hybrid solutions. A SCADAservere may be deployed as a standalone server or as part of a redundant, scalable architecture with load balancing and disaster recovery capabilities.

Security considerations are central to SCADAservere design. Practices include network segmentation, access control, secure communication (encryption in transit), regular patching, and auditing. Compliance with standards such as IEC 62443 and NIST SP 800-82 is commonly referenced.

Terminology note: because SCADAservere is not a standardized term, readers should verify its precise role in each implementation, as it can refer to different software layers or vendor-specific products.
