Technical Specifications Breakdown

The BMXP3420302 offers a robust set of specifications. It supports 4 racks and 11 slots, with a discrete I/O processor capacity of 1024 I/O for multi-rack and 704 I/O for single-rack setups. Analog I/O capacity reaches 256 I/O for multi-rack and 66 I/O for single-rack configurations. The module includes 36 application-specific channels. Memory includes internal RAM of 4096 kB, with 256 kB for data and 3584 kB for program constants and symbols. It executes Boolean instructions in 0.12 µs and floating-point operations in 1.16 µs. Current consumption is 135 mA at 24 V DC, supplied via the rack.

Industry Applications

In manufacturing plants, the BMXP3420302 controls assembly lines with precision, leveraging its CANopen master bus for motion control of independent axes. In process industries, it manages analog inputs from sensors and actuators, ensuring accurate data collection. Its Ethernet TCP/IP port enables integration with supervisory systems for real-time monitoring and data exchange.

Installation & Setup Guidance

Mount the BMXP3420302 on a Modicon M340 rack using the internal power supply connection. Ensure the supplied memory card (BMXRMS008MP) is inserted for program backup and web server activation. Connect the CANopen bus via the SUB-D 9 connector with twisted shielded pairs, and the Ethernet port via RJ45. Configure communication parameters using the embedded services like Modbus TCP messaging and SNMP network management.

Compatibility & Integration

The BMXP3420302 integrates seamlessly with Modicon M340 racks and supports up to 2 Ethernet communication modules and 4 AS-Interface modules. It communicates via CANopen (DS 301, DS 303-2, DS 405) with up to 63 server devices and Ethernet TCP/IP at 10/100 Mbit/s. The module also features a USB port at 12 Mbit/s for local programming.

Maintenance & Reliability

Routine inspection of the BMXP3420302 ensures long-term reliability. Operate within an ambient temperature range of 32 to 140 °F (0 to 60 °C) and relative humidity of 10 to 95% without condensation. The IP20 protection rating suits clean indoor environments. Check status LEDs for network activity, bus faults, and processor errors to quickly identify issues.

Selection Guide & Purchasing Advice

Before purchasing the BMXP3420302, verify your rack configuration and I/O requirements. Ensure compatibility with your existing Modicon M340 system and confirm the need for CANopen or Ethernet communication.
