Programmable controller

Schneider Electric has released the Modicon M340 programmable controller which complements its Modicon Premium (medium to large controllers) and Quantum (large to extra large controllers) for industry and infrastructures.

With 4 MB of internal memory, the Modicon M340 can manage applications up to 70,000 instructions and up to 256 KB of data. The processor includes a USB port and two communication ports for CANopen, ethernet and/or Modbus.

Data is automatically backed up on the internal flash memory and no battery is required, reducing maintenance, or alternatively applications can be automatically backed up on an SD Card. This card's 'Plug & Load' technology enables easy updating of applications and the ability to transfer applications onto other machines with no disruption of operation. Data and maintenance files can be stored and easily accessed from a PC or by simple drag-and-drop via FTP client from the SD Card.

Modicon M340 can be programmed via USB port or ethernet. Machines can be remotely monitored via modem or standard ADSL link. The embedded web server allows the operator to program online, transfer programs, access data files and manage remote operations and diagnostics.

Its compact size means the Modicon M340 can fit easily into tight spaces. The Modicon M340 is also flexible with rack configurations of four to 12 modules and a maximum density of 64 channels per module. Each module is 'hot swap' designed and automatically reconfigured by the CPU at replacement.

Modicon M340 adapts to severe industrial environments exceeding IEC standards. In addition, Modicon M340 conforms to the RoHS European Directive on environment protection.
