One platform, multiple
industrial operating modes.
AI-PLC Core is more than a compact controller. It can run local control, expose remote I/O, generate Modbus RTU and TCP requests, simulate a Modbus device map, bridge data to MQTT-based systems, support future OPC UA interoperability and be developed in a modern VS Code and ESP-IDF workflow. The ESP32-S3 platform also provides hardware headroom for future TinyML / Edge AI functions.
Remote I/O
Acts as a compact remote I/O node, exposing local digital and analog signals to external controllers, PLCs, HMIs or SCADA systems.
02 / REMOTE I/OModbus Gateway
Creates its own Modbus RTU Master and Modbus TCP Client requests to acquire data from external industrial devices and integrate them into the platform.
03 / MODBUS GATEWAYModbus Device Simulator
Can emulate a configurable virtual Modbus map with coils, discrete inputs, holding registers and input registers for HMI, SCADA, testing and commissioning workflows.
04 / SIMULATORMQTT / Edge Gateway
Publishes local data and Modbus-acquired variables to MQTT-based SCADA, edge and cloud applications, enabling lightweight industrial data integration.
05 / MQTT EDGEVS Code Development
Application development is performed in Visual Studio Code, giving users a modern and familiar workflow for building and maintaining industrial applications.
06 / VS CODEESP-IDF + Core API
Built around Espressif IDF and programmed through the AI-PLC Core API + SDK, combining low-level platform power with a higher-level application model.
07 / IDF + APIOPC UA Ready
Architecture prepared for future OPC UA connectivity to expose structured process data, variables and diagnostics to industrial SCADA and interoperability platforms. Core OPC UA software support is planned and is not yet implemented.
08 / OPC UATinyML / Edge AI Ready
The ESP32-S3 with 8 MB PSRAM is prepared for future on-device inference, diagnostics and anomaly-detection workloads. Core software support is planned and is not yet implemented.
09 / AI READYDIN-Rail Enclosure
Designed for installation inside a standard DIN-rail cabinet enclosure. Approx. enclosure dimensions: 159 × 90 × 58 mm, for mounting on a standard 35 mm DIN rail.
10 / DIN-RAILArchitecture
The product value is in the platform stack and deployment flexibility.
AI-PLC Core is defined by its own runtime, API and SDK. The Loong Socket module provides the compute foundation, while AI-PLC Core adds the software stack, the flexibility to work as a standalone controller, remote I/O node, Modbus gateway, simulator or MQTT edge device, a development workflow based on Visual Studio Code and Espressif IDF, planned OPC UA interoperability, and hardware capability for future TinyML / Edge AI workloads. OPC UA and TinyML / Edge AI Core software support are planned and not yet implemented.
Own Core Runtime for platform execution and control services.
Core API for structured software access to features and services.
Core SDK for application development, integration and productization.
