Insol-Node is an Edge Computing hardware-software platform for industrial automation, combining 4diac runtime, PostgreSQL, OPC UA server and web-SCADA into a single device. Built on a managed 10BASE-T1L Single Pair Ethernet switch, the device is designed to deploy distributed, cabinet-free data acquisition and control systems based on the IEC 61499 standard.

Key Advantages:
► unlimited number of tags, archives, and client connections - no "per-tag" licensing fees
► all-in-one upper level in a single device: 4diac, PostgreSQL, OPC UA and web-SCADA
► adaptation to the specific requirements and volume of field equipment
► reliable network transmission, efficient control and high system response speed
► SPE support based on 10BASE-T1L and PoDL - significant reduction in infrastructure and cable count
► connection of diverse field devices and their integration into a unified control system
► operation across a wide range of climatic conditions and working parameters

Service Functions:
► lightweight and cross-platform application
► visualization tools
► alarm management - event notification
► reporting
► scripting
► connectivity
► trend charts
► user management

Proprietary Hardware and Software
Insol-Node is a proprietary development by Insol Technology LLP: both the hardware and the software platform are designed and manufactured in-house. The entire upper level of the industrial control system (ICS) runs on open-source and free software, free from foreign proprietary licenses. This makes the solution fully compliant with supply chain resilience and technological independence initiatives.

All-in-One Solution
The entire upper level of the ICS is integrated into a single device: the runtime environment, DBMS, OPC UA server, and web-SCADA come pre-installed and interconnected out of the box. This completely eliminates traditional integration costs, bypassing the need for separate SCADA servers, external OPC servers, historians, or databases with individual licenses.

Zero Per-Tag Licensing Fees
The technology stack is built on open-source software (4diac Forte, PostgreSQL, OPC UA, FUXA), meaning there is no "per-tag" pricing, and no licensing fees for client connections or historical data archiving. The number of variables (tags), archives, and active connections is limited solely by the physical resources of the hardware, not by a license key.

Traffic Prioritization and Reliable Control
The switch's feature set enables packet prioritization, ensuring a guaranteed time slot for each connected device. Rigidly fixing the polling priority of field devices maintains the absolute reliability of the core process control algorithm.

PostgreSQL Database
PostgreSQL is a powerful, open-source object-relational database system. It utilizes and extends the SQL language combined with a robust feature set to safely store and scale even the most complex data workloads.
