TORONTO – SCHNEIDER ELECTRIC’s new Telemecanique Modicon M340(TM) PLC is a rugged, compact, and user-friendly controller ideally suited for most applications. Its small size packs surprisingly high performance and allows the M340(TM) to fit seamlessly into solutions for mining and many other industries, says the manufacturer. The M340 joins Schneiders rugged family of Modicon PLCs including the Modicon Premium(TM) and the Modicon Quantum(TM), known for their dependability and power.

Modicon M340 PLCs are built for ease of use. They have both high-speed USB ports and customizable communication ports. Users can program online, transfer programs, access data files and manage remote operation and diagnostics thanks to open TCP standards and the embedded web server functions. This openness ensures users can access their machines in complete security from anywhere on the floor, the office or remotely.

These controllers have a 4-Mb internal RAM that can manage applications up to 70 k instructions and 256 Kb data. Data are automatically backed up in an internal flash memory and the application in an SD card format. Data files or maintenance files can also be stored and easily accessed from a PC or by simple “drag-and-drop” via FTP. Each M340 module is hot swap designed and automatically configured by the CPU when inserted into the backplane.

The new Modicon M340 maximizes efficiency and performance with Unity(TM) – Schneider’s world-class development platform that uses common tagging and a single database for development tasks across a range of Schneider automation products. Unity allows the user to concentrate on the process, not the configuration. As a result, development and downtime are reduced and productivity and uptime are maximized.

Solutions based on the feature-packed M340 and Unity team are simple to design and implement and easy to maintain. For more information on M340 PLCs, visit
