Schneider Electric BMXP342020 Modicon M340 Processor 1024 I/O Modbus Ethernet Programmable Logic Controller

The Schneider Electric BMXP342020 is a Modicon M340 processor module supporting up to 1024 discrete and 256 analog I/O across 4 racks, with Modbus, Ethernet TCP/IP and a USB programming port. It executes at 6.4 to 8.1 Kinst/ms and stores programs on a removable SD memory card, serving as the central CPU of small-to-mid M340 process control and machine automation systems.

Selection Notes

BMXP342020 offers RS232/RS485 serial plus Ethernet and USB connectivity without an integrated CANopen master, distinguishing it from the CANopen-equipped variant in the same processor family used for independent-axis motion control. Choose this model when the application needs Modbus RTU/ASCII legacy device integration over serial links rather than CANopen networking. Its 1024 discrete / 256 analog I/O capacity across 4 racks and 6.4 to 8.1 Kinst/ms execution speed suit small-to-medium process and machine control applications that do not require axis-level motion coordination.

Applications

Used in process industries, water and cement plants, renewable energy installations and machine or infrastructure automation where Modbus and Ethernet TCP/IP connectivity link the PAC to distributed I/O and third-party devices.
