What's NexPLC controller

An Open, Connected, and Intelligent PLC for the IT/OT Era

NexPLC is a new-generation industrial controller designed for Industry 4.0 and smart manufacturing, developed by Beilai Technology.
It breaks the limitations of traditional PLC systems by deeply integrating control, data acquisition, protocol interoperability, and cloud connectivity into a single, open platform.

Built on an enhanced OpenPLC core, NextPLC is not just a PLC—it is an IT/OT convergence controller that enables seamless communication between field devices, automation systems, and cloud platforms.

Why NexPLC?

Traditional PLCs suffer from two fundamental problems:

• Closed ecosystems
  Vendor-locked software, proprietary protocols, and poor interoperability increase system cost and integration complexity.

• Limited connectivity
  Connecting meters, building systems, energy devices, or third-party PLCs often requires multiple gateways and complex configurations.

NexPLC solves these problems by offering an open architecture, multi-protocol communication, and cloud-ready design—right out of the box.

Core Capabilities

1. Standardized PLC Programming (IEC 61131-3)

NexPLC fully complies with the IEC 61131-3 international PLC standard and supports:

• Ladder Diagram (LD)

• Function Block Diagram (FBD)

• Structured Text (ST)

• Sequential Function Chart (SFC)

• Instruction List (IL)

A modern engineering environment allows mixed-language programming, improving code reuse, readability, and long-term maintainability.

2. Open Communication & Multi-Protocol Integration

NexPLC is designed as a protocol-native controller, not a closed PLC with limited interfaces.

Supported protocols include:

• Field / Downstream

  • Modbus RTU / TCP

  • BACnet IP / MS-TP

  • DLT645

  • IEC 104

  • Mitsubishi / Siemens / Omron / Delta PLC protocols

• Upstream / IT Systems

  • OPC UA

  • MQTT

  • Modbus TCP

  • BACnet/IP

  • SNMP

This allows direct communication with HMI, SCADA, MES, EMS, and cloud platforms—without external gateways.

3. Cloud & Edge-Ready Architecture

NexPLC supports seamless integration with major platforms such as:

• AWS IoT Core

• Huawei Cloud

• Alibaba Cloud

• ThingsBoard

• Ignition SCADA

With built-in edge computing and data preprocessing, PLC logic can directly interact with cloud data, enabling:

• Cross-system control logic

• Data-driven automation

• Predictive maintenance

• Remote analytics

4. Flexible Hardware Architecture

NexPLC is available in multiple hardware forms to match different project scales:

Compact All-in-One Controller

• Dual Ethernet + RS485

• Pluggable I/O expansion

• Digital I/O, Analog I/O, RTD, Thermocouple, RS232/485

• Up to 219 I/O combinations

• Ideal for compact machines and small automation projects

Distributed I/O Architecture

• Controller + distributed I/O modules

• Up to 32 expansion modules per controller

• High-density digital, analog, and temperature acquisition

• Ideal for medium and large automation systems

Industrial-grade design ensures EMC robustness, wide-voltage power input (12–24V DC), and long-term reliability.

5. Modern Engineering Experience

NexPLC provides a next-generation PLC IDE focused on usability and efficiency:

• One-click compile, upload, and run

• Visual protocol configuration & data mapping

• Real-time variable monitoring

• Graphical point mapping across protocols

Compared with traditional PLC tools, common engineering tasks are reduced by over 50%, significantly shortening project delivery time.

6. Remote Maintenance & Lifecycle Management

With integrated remote access tools, NexPLC supports:

• Remote program upload/download

• Online debugging and monitoring

• Device health diagnostics

• Batch firmware upgrades

This dramatically reduces on-site maintenance costs and enables centralized lifecycle management.
