Product description

The three general-purpose controllers together form a family called Modicon M2X which is part of the MachineStruxure portfolio. They share an expansion bus claimed to be ten times faster than conventional systems. The controllers are:

The entry-level Modicon M221 (below) - a 24 I/O logic controller for basic hard-wired applications, claimed to offer best-in-class performance. It includes two analogue inputs, Ethernet, USB and serial ports, and an SD memory card slot. It can be expanded using up to 14 modules including motor starters, safety modules, and analogue and digital I/O. Up to two servo amplifiers can be connected without needing a fieldbus network.

The more powerful Modicon M241 is based on a dual-core processor and supports CANopen communications. A built-in Web server allows remote access via mobile devices such as smartphones and tablets.

The Modicon M251 (below), which is aimed at distributed architecture applications, replaces the I/O terminal array of the first two M2X controllers with ports for two different Ethernet networks and has a built-in Ethernet switch. An alternative version incorporates a CANopen master interface (supporting up to 63 slaves), along with one Ethernet port and an Ethernet switch.

As well as the high-speed expansion bus (called Modicon TM3) for I/O and safety modules on the right-hand side of the Modicon M241 and 251 controllers, they also accept up to three stackable communications modules on their left-hand sides using a bus called Modicon TM4.
