It supports up to 64 event tasks, one periodic fast task, and one master cyclic task, optimizing task management within your application.

From a hardware perspective, the processor is compact and lightweight, measuring approximately 11.5 x 11 x 5.5 cm and weighing only 0.205 kg. Its power consumption is efficient, drawing just 95 mA at 24V DC through the internal rack supply. Diagnostic LEDs offer real-time visual feedback for system status, Ethernet activity, I/O faults, and memory card errors.

Connectivity is one of the BMXP342020's standout features. It supports Ethernet communication at 10/100 Mbps and has embedded services like Modbus TCP messaging, bandwidth management, SNMP network admin, and a built-in web server. These features allow real-time remote monitoring, configuration, and troubleshooting, boosting system reliability and minimizing downtime.

For serial communication, the module offers flexible options with RJ45 ports supporting both character and Modbus transmission modes. These ports operate over twisted shielded pairs, delivering reliable data transfer across varying distances, from 10 meters in non-isolated configurations to up to 1000 meters in isolated setups.

Environmental robustness is another strength. The BMXP342020 operates in temperatures ranging from 0°C to 60°C and humidity levels from 10% to 95% non-condensing. It carries IP20 protection and is compliant with multiple international standards like CE, UL, CSA, and Marine certifications, ensuring safe deployment even in demanding industrial conditions.

Installation is seamless with support for up to four racks and eleven module slots. Its compact footprint makes it suitable for space-constrained control panels. The device is pre-treated with protective coatings for extended durability, even in environments exposed to dust or humidity.

Memory protection and program backup are ensured with the supplied BMXRMS008MP card. This allows backup of programs, constants, symbols, and real-time data, enhancing system resilience against unexpected shutdowns or power failures. The same card also activates the built-in web server and enables remote diagnostics via a browser.

The processor module offers multiple layers of error handling and communication diagnostics. With LED indicators for Ethernet status, communication activity, and module errors, engineers can identify faults instantly and take corrective actions with minimal effort.

It supports both character mode and Modbus communication protocols, offering a wide range of compatibility with third-party devices and legacy systems. Whether you're developing a new automation infrastructure or upgrading an existing setup, this module ensures flexible deployment without compatibility issues.

Designed for performance, the BMXP342020 meets industry standards such as EN 61131-2 and EN/IEC 61850-3. It is suitable for use in hazardous environments classified under class I division 2, making it reliable even under tough industrial conditions like electrical substations or marine control systems.

For high-speed control tasks, the BMXP342020’s rapid task execution and minimal system overhead ensure precise response times. The fast task has a system overhead of only 0.13 ms, while the master task maintains efficient timing at 0.7 ms—ideal for real-time processing in mission-critical automation.

The product ships in durable packaging that ensures safe delivery, with a primary package weighing around 245 grams and bulk packaging options for large-scale installations. It is available individually or in groups of 15 for convenient inventory and project handling.

With a host of features including fast execution, scalable memory, broad communication options, and rugged build quality, the Schneider BMXP342020 is a dependable choice for control engineers and automation professionals.
