Product Description

The cMT-CTRL01 is a programmable logic controller integrating CODESYS and an IIoT gateway, primarily targeting industrial IoT and smart manufacturing applications. Below is an overview:

Hardware Configuration

Processor: Dual-core RISC central processing unit.

Memory: Equipped with 4GB Flash memory, 512MB RAM, plus 3MB of Data/Memory/Code memory. Reserved and persistent areas each occupy 16KB, with an 8MB file system.

Communication Interfaces: Features one 10/100/1000Base-T Ethernet port and one 10/100Base-T Ethernet port. COM1 is an RS-232 2-wire interface, COM2 is an RS-485 2-wire/4-wire interface, and COM3 is an RS-485 2-wire interface.

Other: Supports SD/SDHC cards, built-in real-time clock, operates on 24±20% VDC power supply with integrated power isolation. Dimensions: 50x109x81mm, weight: approx. 0.24kg. Mounted via 35mm DIN rail with aluminum rail mounting. IP20 protection rating.

Software & Programming

Programming Standards: Built-in CODESYS complies with IEC 61131-3 PLC standards, supporting multiple programming languages including FBD, LD, IL, ST, SFC, and CFC.

Protocol Support: As a gateway, it supports IIoT protocol standards like OPC UA and MQTT, along with protocols such as Modbus TCP/IP Master and EtherCAT Master. It also features a built-in Modbus TCP/IP gateway supporting protocols for over 300 mainstream PLC brands.

Remote Services: Authorized users can activate EasyAccess 2.0 to update CODESYS projects and monitor device status. Through EasyAccess 2.0's push notifications, users receive real-time operational error alerts on mobile devices.

Key Features

Data Processing: The IIoT gateway supports data sampling and event logging. Historical data can be stored on SD cards or synchronized to SQL databases.

Port Flexibility: Dual Ethernet ports offer versatile allocation. One can be dedicated to CODESYS while the other serves the IIoT gateway, or both can function as IIoT gateways—one connecting to a host computer or the internet, the other linking to field Ethernet-based PLCs.

Application Scenarios

The cMT-CTRL01 is suitable for industrial IoT and smart manufacturing scenarios. It connects industrial equipment from different brands, converts protocols, and uploads device data to industrial IoT data platforms. This enables production equipment monitoring, data acquisition and analysis, and remote operation and maintenance, helping factories achieve intelligent upgrades and automated control. It can also be flexibly combined with iR series modules to expand the system according to application requirements.

Frequently Asked Questions

Q: What is the primary purpose of the cMT-CTRL01 controller?
The cMT-CTRL01 integrates CODESYS PLC features with an IIoT gateway. It is designed to bridge different industrial protocols, handle data processing/logging, and transmit operational data to industrial IoT platforms for smart manufacturing application environments.
Q: Which programming standards and languages does the CODESYS system support?
The built-in CODESYS complies with the IEC 61131-3 standard, allowing engineers to program using multiple languages such as FBD (Function Block Diagram), LD (Ladder Diagram), IL (Instruction List), ST (Structured Text), SFC (Sequential Function Chart), and CFC (Continuous Function Chart).
Q: Can the dual Ethernet ports be configured independently?
Yes. The dual Ethernet ports provide flexible configurations. You can assign one port to CODESYS tasks and the other to IIoT gateway operations. Alternatively, both ports can act as IIoT gateways, with one connecting to your local PLCs and the other to an upstream PC or the internet.
Q: How is operational data stored or backed up?
The controller supports data sampling and event logging features. All historical operational records can be logged on an external SD card or synchronized automatically with remote SQL databases.
Q: What are the installation dimensions and mounting type of the unit?
The unit measures 50 x 109 x 81 mm and weighs approximately 0.24 kg. It features a plastic enclosure designed for standard 35 mm DIN rail installation.
Q: Does this controller support expansion modules?
Yes. The cMT-CTRL01 can be integrated with iR series I/O expansion modules through its internal iBus communication protocol to expand overall system capacity as needed.
