4 Presentation Modicon M251 logic controllers General presentation Presentation Applications Modicon M251 controllers offer an innovative, high-performance solution in the ield of modular machines and distributed architectures. Thanks to their compact dimensions, they can optimize the size of wall-mounted and floor-standing control system enclosures. Since Modicon M251 controllers have no embedded I/O, field devices such as variable speed drives and remote I/O are connected on either the CanOpen bus or the Ethernet network. Modicon M251 controllers have an embedded Ethernet port offering FTP and web server services, meaning they can easily be integrated in control system architectures, for remote monitoring and maintenance of machines by means of applications for smartphones, tablets and PCs. The wealth of embedded functions minimizes the cost of the machine: - Functions embedded in the controller: Modbus serial link, USB port dedicated to programming, CANopen fieldbus for distributed architectures and advanced position control functions (PLCopen libraries). - Functions embedded in Modicon TM3 extensions: functional safety modules, motor-starter control module and remote expansion system. - Functions embedded in Modicon TM4 communication modules. The processing power and the memory size of M251 controllers are ideal for targeting high-performance applications. SoMachine's programming software is powerful and intuitive, making it quick to create applications. Existing applications can easily be retrieved from the Modicon M221, M238 and M258 ranges, maximizing use of the investment already made. Main functions v Both Modicon M251 logic controllers come in an identical format (w x h x d): 54 x 90 x 95 mm (2.13 x 3.54 x 3.74 in). v Modicon M251 controllers have no embedded I/O but can be combined with Modicon TM3 expansion modules. v Each M251 controller has a Run/Stop switch. v Each M251 controller has a slot for an industrial SD (Secure Digital) memory card. v Each M251 controller has a QR code for direct access to its technical documentation. Embedded communication M251 logic controllers have up to 5 embedded communication ports. v Embedded in the TM251MESE controller are: - an Ethernet 1 network (1) with 2 RJ 45 ports connected by an internal switch, this network being mainly for communication between machines or to your factory network - an Ethernet 2 network (1) with an RJ 45 port, optimized for connecting field devices (variable speed drives, distributed I/O, etc.) by means of the Ethernet I/O scanning service (Industrial Ethernet Manager). This port can also be connected to a factory network v Embedded in the TM251MESC controller are: - an Ethernet network (1) with 2 RJ 45 ports connected by an internal switch, this network being more specifically dedicated to communication between machines or to your factory network - a master CANopen port for connecting field devices (variable speed drives, distributed I/O, etc.) v In addition, both these M251 logic controllers incorporate: - a serial link port - a programming port (1) Ethernet with embedded Web server function. Processing power v Execution speed: 22 ns/Boolean instructions v Program: 128 Boolean Kinstructions v DualCore processor v RAM: 64 MB. Flash memory: 128 MB Programming Modicon M251 logic controllers are programmed with the SoMachine software, Please consult on our website: www.schneider-electric.com SoMachine software TM251MESE TM251MESC Example of a QRcode: QRcode for access to the TM251MESC logic controller technical documentation Compatibility of offers Modicon M251 logic controllers > Modicon TM3 expansion modules > Modicon TM2 expansion modules > TM4 communication modules > SoMachine software 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 7 8 9 10
