Entry-level Modicon M221 controller from Schneider Electric
The Modicon M221, the entry-level model of the Modicon family of controllers, is part of an innovation package for MachineStruxure, Schneider Electric's automation offering for machine building. It's surprising combination of performance, interfaces, and modularity sets it apart from other controllers in its class.
Schneider's Modicon M221 controller is designed for machines automated with hardwired controller architectures. In addition to the standard format, it is also available in a compact book format. The Modicon M221 is described as one of the fastest controllers on the market in its class, making it suitable for applications with up to mid-level performance requirements.
An integrated Ethernet interface allows the controller to fully accommodate the trend toward incorporating even simple applications into modern communication systems. The basic configuration also includes a USB interface for programming, as well as a serial interface. An integrated pulse/direction interface for connecting servo drives is also standard in this controller.
There are 24 I/O terminals in the standard format, while the book format has 16. The Modicon TM3 I/O system, which was specially developed for the new controller series, allows flexible and customisable expansion of both formats. Up to 14 terminals can be added to the controllers, with no tool requirements, and the high-speed bus is 10 times faster than traditional approaches.
The new safety system modules can also be added to the controllers via the I/O expansion bus. Individual controller configurations, including safety functionalities, can be created using standard I/O modules and safety relays in different configurations on the same expansion bus, without the need for additional, separately installed safety relays.
Program data is saved on SD cards, which are easy to transport or switch out. Another feature is the ability to use a PC to install program and/or firmware data on the controllers even when they are powered off.
Engineering with the Modicon M221 is made even easier thanks to a special configuration of the SoMachine programming tool, which deactivates all irrelevant functionalities while supplementing the functionalities needed for programming the HMI application in the tool. Intuitive user guidance also means that training is no longer required before using the software. SoMachine Basic is freeware and can be downloaded from the Schneider Electric website. Programs created with SoMachine Basic are naturally IEC 61131-3-compliant and can be upgraded to the full version of SoMachine.
