BMXP342020 – Modicon M340 – Processor – 1,024 Digital I/O – 256 Analog I/O – 1 Modbus – 1 Ethernet

This processor module is part of the Modicon M340 automation platform. This high-performance processor supports up to 4 racks and 1,024 I/O points, with a 4,096 KB memory capacity.

The front panel features a security screw for locking the module into its slot, as well as a display block with 8 LEDs for status and diagnostic information.

The processor is equipped with:

A Mini-B USB connector for connection to a programming terminal
A dedicated slot containing its Flash memory card
An RJ45 connector for connection to the Modbus/TCP Ethernet network
An RJ45 connector for Modbus serial communication or character mode communication (RS-232C / RS-485, 2-wire, non-isolated)

The processor is supplied as standard with an SD (Secure Digital) Flash memory card, designed to back up the two memory areas of the processor module’s internal RAM, including the application program.

The SD Flash memory card also provides backup for:

Symbols and comments
Program constants
Application data

Data is automatically backed up by duplication when the PLC is powered down. Likewise, data restoration is transparent to the user when power is restored.
