EM300 – Modular Industrial Edge Controller for Plug-and-Play I/O Expansion & Edge Computing

IOT Applications

1. Distributed Control in Edge Environments

Industrial automation systems often require separate PLCs, I/O modules, and communication gateways, increasing system complexity and deployment cost.

The EM300 consolidates edge control, modular I/O expansion, protocol communication, and networking into a single compact platform.
With scalable I/O modules, field signals can be expanded flexibly without redesigning the control architecture.

Built-in Node-RED enables local logic execution for equipment coordination, alarms, and real-time control.

2. Connecting Legacy Devices to Modern IoT Systems

Many industrial sites still rely on RS485 devices and PLC-based systems, making cloud integration and remote data access difficult.

The EM300 bridges legacy equipment and modern IoT platforms by supporting multiple industrial protocols and enabling direct integration with MQTT, HTTP, and SCADA systems.
Edge processing reduces cloud load while ensuring faster local response.

3. Remote Operation for Distributed Industrial Sites

Remote industrial environments often require multiple standalone devices for networking, security, and maintenance.

The EM300 integrates VPN, firewall, remote access, and device management into a single edge platform, enabling unified remote operation.
Automatic reconnection and retransmission mechanisms help maintain stable communication in unstable network conditions.

Core Advantage

Instead of separating PLC, I/O, gateway, and networking functions into multiple systems, the EM300 unifies them into a single edge architecture.

This reduces system complexity, simplifies deployment, and enables faster commissioning in distributed industrial applications.

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

Q1. What’s the fundamental difference between EM300 and a traditional industrial gateway?

A1: The EM Series industrial edge controller is not just an industrial gateway. It is an edge computing + distributed control and data acquisition platform.

Traditional industrial gateways are mainly used for protocol conversion and data forwarding to the cloud.
In contrast, the EM Series can handle everything directly at the field level:

•Distributed I/O signal acquisition (DI/DO/AI/AO with flexible expansion)
•Real-time control logic execution (millisecond-level response)
•Multi-protocol device integration and unified management
•Edge data processing with cloud connectivity

It combines data acquisition, control, communication, and maintenance into one programmable industrial execution system, instead of being just a data transfer device.

Q2. What protocols does the EM300 support?

A2: The EM300 Controller supports a wide range of industrial communication protocols for device integration and data acquisition, including:

• Modbus RTU, Modbus TCP
• PLC communication protocols such as SIEMENS, MELSEC, OMRON, LS Electric, Allen-Bradley, Delta, and other mainstream PLC brands
• CNC communication protocols such as SIEMENS, MELSEC, Mazak, Heidenhain, Haas, KND, LNC, and other CNC brands
• Industrial and IoT protocols including MQTT, OPC UA / OPC DA, HJ212, and IEC104
• Common network communication protocols such as HTTP, TCP, UDP, and WebSocket

For non-standard or proprietary protocols, users can implement custom parsing and logic through JavaScript (JS).

Q3. Can EM300 replace a PLC?

A3: For lightweight automation, remote monitoring, and edge logic applications, EM300 can reduce PLC dependency by integrating I/O, logic control, networking, and remote maintenance into one device.
