What Is Schneider Modicon M340 PLC?

The Modicon M340 is a modular controller platform designed for applications that require more flexibility and expansion than a compact machine PLC.

An M340 system can combine:

• Processor

• Rack and power supply

• Digital I/O

• Analogue I/O

• Communication modules

• Expert/technology modules

• Modicon X80-compatible modules

Schneider's M340 documentation identifies the platform as suitable for industrial process and infrastructure control and highlights Ethernet, CANopen, Modbus serial communication and compatibility with Modicon X80 modules.

Why Use an M340 PLC?

Industrial automation systems often need a controller that can handle multiple I/O types while communicating with HMIs, drives, remote devices and supervisory systems.

The M340 architecture provides a practical platform for:

• Machine and equipment control

• Process monitoring

• Distributed I/O

• Analogue signal processing

• Industrial communication

• Data exchange with supervisory systems

• Automation system expansion

Its modular structure also allows the hardware configuration to be adapted according to the application.

Main Components of an M340 Automation System

1. M340 Processor

The CPU executes the automation application and manages the configured I/O and communication functions.

Different processor references are available for different application requirements, so the exact CPU should be selected according to program size, I/O architecture, communication requirements and performance needs.

2. Racks & Power Supplies

The processor and compatible modules are installed within the appropriate M340/X80 rack architecture.

The rack and power-supply selection depends on the number and type of modules required.

3. Digital I/O

Digital input and output modules allow the PLC to interface with:

• Sensors

• Push buttons

• Limit switches

• Contactors

• Relays

• Solenoid valves

• Motors and actuators

4. Analogue I/O

Analogue modules allow the controller to process continuously varying signals such as:

• Temperature

• Pressure

• Flow

• Level

• Speed reference

• Process measurement

5. Communication Modules

Communication modules can be selected according to the network and equipment requirements.

Schneider's M340 documentation includes Ethernet, CANopen and Modbus serial communication capabilities, while additional communication modules can extend the system according to the application.

Modicon M340 & X80 I/O

A major advantage of the M340 architecture is its relationship with the Modicon X80 I/O platform.

Schneider describes X80 as a common module platform used with M340, M580 and Quantum Ethernet I/O systems. It includes digital, analogue, expert and communication modules.

This common platform can simplify:

• I/O selection

• Spare-parts management

• Engineering

• Maintenance

• System expansion

• Training requirements

M340 Communication Options

Communication is an important part of modern automation systems.

Depending on the selected hardware, M340 systems can communicate with:

• HMIs

• SCADA systems

• Variable-speed drives

• Remote I/O

• Industrial equipment

• Supervisory systems

• Other PLCs

Ethernet Communication

M340 systems can use Ethernet-based communication for supported industrial protocols and system integration.

Schneider confirms that the M340 platform can support EtherNet/IP through the BMXNOC0401 module.

Modbus TCP

The M340 Ethernet interface supports Modbus TCP/IP communication. Schneider's current technical guidance also documents Modbus TCP operation on M340 Ethernet ports.

CANopen

CANopen communication is available for supported M340 architectures and can be used for machine and installation-bus applications. Schneider includes CANopen among the M340 platform's communication capabilities.

Modbus Serial

M340 systems can also support Modbus serial communication through the appropriate interface or module.

M340 PLC Programming Software

The Modicon M340 PLC is programmed using EcoStruxure Control Expert, formerly known as Unity Pro.

Schneider explicitly states that M340 can only be programmed using Control Expert and supports the S, L and XL software versions.

Control Expert provides an engineering environment for:

• PLC programming

• Hardware configuration

• I/O configuration

• Communication setup

• Diagnostics

• Application testing

• Commissioning

• Maintenance

Schneider also identifies Control Expert as the common IEC programming platform for Modicon M340, M580, Momentum, Premium and Quantum applications.

M340 Programming Languages

Depending on the application and Control Expert configuration, engineers can work with IEC 61131-3 programming languages including:

• Ladder Diagram

• Function Block Diagram

• Structured Text

• Sequential Function Chart

This provides flexibility for both machine-control and process-control programming requirements.
