SCADAlike

SCADAlike is a term used to describe software architectures and systems that imitate key functions of traditional SCADA (supervisory control and data acquisition) systems. Such systems gather real-time data from field devices, present it through human–machine interfaces, log historical data, generate alarms, and support basic remote control, all within a more lightweight or accessible package than a full industrial SCADA installation. SCADAlike solutions are commonly used for prototyping, education, research, and small-scale monitoring projects where formal SCADA deployments are impractical or unnecessary.

Typically, a SCADAlike setup comprises three or more layers: data acquisition interfaces that read sensors or controllers (such as Modbus, MQTT, or OPC UA endpoints), a data store or historian for time-series data, and a visualization/controls layer (HMI or dashboard). Some implementations include scripting or rules engines for automated responses, as well as security and access controls. Open-source tools and commercial offerings frequently enable rapid assembly of SCADAlike stacks on commodity hardware, using standards like OPC UA, MQTT, or REST APIs to connect devices.

In contrast to fully fledged SCADA systems, SCADAlike solutions are usually less feature-rich in terms of redundant architectures, lifecycle management, and formal safety certifications. They are valued for flexibility, lower cost, and easier experimentation, but may require additional hardening for production use.

Safety and security considerations are important, including authentication, encryption, network segmentation, and regular software updates to mitigate cyber risks associated with industrial control-like software.
