Modicon M340

Is a Programmable Automation Controller (PAC) and is built to suit the needs of the process industry and a wide range of demanding automation applications.

  • Included
    • 7 Kinst/ms
    • Multitasking system for guaranteed reflex time
    • Programmed with Unity™ Pro software
    • USB port for programming and HMI
    • Two additional ports as required: Ethernet, CANopen®, Modbus™.


    • Programming code up to 70 Kinst.
    • Application back-up in supplied memory card
    • Additional file storage up to 128 MB with FTP access.


    • Industry-standard network connectivity using CANopen, AS-Interface®, Ethernet or Modbus reduces field wiring and lowers installation costs.
    • Rack expansion capability up to four 12-slot racks for applications with large I/O count requirements.
    • Supports the Highway Addressable Remote Transducer (HART), the protocol for sending and receiving digital information across analog wires between smart devices and a control or monitoring system.
    • Distributed Ethernet I/O for other Modicon PLCs. Modicon M349 Peripheral I/O Adapter
    • Supports Ethernet Modbus TCP/IP and EtherNet/IP™ on the same module without requiring any configuration. The module consists of a four-port switch that also supports a daisy-chain loop on two ports.
      • Ethernet topologies for distributed I/O.
      • Ethernet I/O ring communications.
      • Ethernet daisy chain topologies.
      • Ethernet ring topologies with Modicon M340 PACs.
      • Ethernet complex, self-healing ring topologies.

    Specific applications

    • Integrated RTU solution for Water, Oil & Gas, Power & Infrastructure; supports DNP 3.0 and IEC60870-5 serial or Modbus TCP/IP connections
    • Process control (Integrated Process Control library)
    • High density analog I/O modules
    • Counting Pulse Train Output (PTO) motion module
  • Benefits

    • No battery required
    • Extended temperature (-25°C +70°C) and conformal coating for operation in harsh environments
    • Protection of SI and OEM know-how by the SD card technology

    BenefitsThe Modicon M340 offers in a small form factor flexibility and integrated functions. In the heart of your process, it provides plug-and-play solutions with both Schneider Electric and third party devices. The large capacity of Unity Pro SoCollaborative software will ease and shorten programming and commissioning time.
