Schneider Electric expands automation offerings with new range of Modicon programme logic controllers

Schneider Electric, the global specialist in energy management, has expanded its portfolio with the addition of three new Modicon controllers M221, M241 and M251.

All versions are optimised for Ethernet communication and include a USB interface for programming, as well as a web server for integration into modern communication solutions and remote access.

The controllers use an SD card to save program and firmware, making them easy to transport or switch out without the need for a PC. It is also possible to use a PC to install program and/or firmware data on the controllers, even when they are switched off.

Modicon M221

The Modicon M221 is designed for machines automated with hardwired controller architectures and is available in both compact and standard formats. As one of the fastest controllers on the market in its class, it is suitable for applications with up to mid-level performance requirements. The basic configuration includes a serial interface and there is also an integrated pulse/direction interface for connecting servo drives fitted as standard. The standard format has 24 I/O terminals, while the book format has 16.

The Modicon M251 is specifically designed for tasks in which the controller needs to communicate simultaneously via Ethernet within the machine and at network level. With two Ethernet interfaces and an embedded Ethernet switch, it can communicate in a parallel operation through two Ethernet networks, and can act as an Ethernet master in one of them.

Both the Modicon M241 and M251 are designed for CANopen communication, boasting a wide assortment of interfaces in addition to the field bus connection. The dual-core processor has an impressive performance and allows the controller to work with a consistently short life cycle, even in large-scale communication tasks.

Modicon M251

The I/O terminal block for the Modicon M241 is designed with 5.08 mm spacing, and the terminals can be easily and ergonomically connected by opening a small cover on the housing. The integrated pulse/direction interface is also standard in this controller, as are several high-speed counters.

All controllers are also built with an I/O expansion bus that is 10 times faster than traditional solutions. The Modicon TM3 I/O modules allow flexible and customisable expansion, with potential to add up to 14 terminals with no tool requirements. The new safety system modules can also be added to the controllers via the I/O bus.

All controllers are based on SoMachine, the tool-based engineering suite for all the controllers of the MachineStruxure multi-controller platform. Controller programs can be created in the common languages of the IEC 61131-3 standard and can be ported between the different Modicon controllers.
