Why the BMXP3420302 Fits Modern Automation Needs
Industrial automation demands controllers that handle complex communication and high I/O counts. The Schneider BMXP3420302 processor module from the Modicon M340 platform meets these needs with integrated CANopen and Ethernet TCP/IP. This module supports up to 1024 discrete I/O in multi-rack configurations, making it suitable for medium to large-scale systems.
With a 0.12 µs Boolean execution time and 8.1 Kinst/ms for 100% Boolean logic, the BMXP3420302 delivers fast processing for time-critical tasks. Engineers can rely on its deterministic performance for applications like packaging, material handling, and machine control.
Technical Specifications and Performance
The BMXP3420302 includes 4096 kB internal RAM, with 3584 kB allocated for program, constants, and symbols. It comes with a supplied BMXRMS008MP memory card for backup and web server activation. The module supports 64 event tasks, one cyclic/periodic master task, and one periodic fast task, offering flexibility for diverse control strategies.
Communication is a strong suit: the processor integrates a CANopen master bus with speeds from 20 kbit/s to 1 Mbit/s, and an Ethernet TCP/IP port at 10/100 Mbit/s. It also includes a USB port at 12 Mbit/s for local programming. The module can manage up to 63 CANopen slave devices and supports daisy-chaining or tap junctions for network topology.
Current consumption is 135 mA at 24 V DC, supplied via the rack. The operating temperature range is 32 to 140 °F (0 to 60 °C), with an IP20 degree of protection. Certifications include CE, UL, CSA, RCM, EAC, and Merchant Navy, ensuring compliance with global standards.
Applications in Modern Manufacturing
In a typical packaging line, the BMXP3420302 can coordinate multiple conveyor sections, labelers, and sealers via CANopen. Its 256 analog I/O capacity in multi-rack setups allows precise control of temperature, pressure, and speed. The Ethernet port enables seamless integration with higher-level SCADA or MES systems for data collection and remote monitoring.
For material handling, the module's motion control capabilities over CANopen support independent axis control. This is useful for sortation systems or automated guided vehicles where synchronized movement is critical. The 64 event tasks can capture fast sensor inputs without missing a beat.
Integration with Existing Networks
The BMXP3420302 supports up to two Ethernet communication modules and four AS-Interface modules, expanding its connectivity. Embedded services include Modbus TCP messaging, SNMP network administration, and a Rack Viewer for diagnostics. The CANopen interface complies with DS 301 V4.02, DS 303-2, and DS 405 profiles, ensuring interoperability with a wide range of devices.
Network management features like NMT, PDO, SDO, and special functions (SYNC, EMCY, TIME) are built in. This makes the module a strong choice for upgrading legacy systems or building new distributed architectures. The Ethernet port also supports bandwidth management and a data editor for easy configuration.
Business Value and ROI
Choosing the BMXP3420302 reduces total cost of ownership by combining multiple communication protocols in one module. Its fast execution speeds minimize cycle times, boosting throughput. The supplied memory card and built-in diagnostics reduce downtime by simplifying troubleshooting and backup.
With certifications for hazardous locations (Class I Division 2) and compliance with EN 61131-2 and EN/IEC 61000-6-5, the module is built for harsh industrial environments. This reliability translates to fewer unplanned stoppages and lower maintenance costs.
