Schneider BMXP3420102 M340 Processor Module 1024 I/O

Schneider BMXP3420102 Modicon M340 Processor Module

Product Introduction

The BMXP3420102 serves as the central processing unit for Modicon M340 automation systems. This processor module delivers robust control capabilities for medium to large-scale applications. It supports multi-rack configurations with up to four racks and eleven slots per rack. Furthermore, the BMXP3420102 offers extensive communication options, making it suitable for diverse industrial automation scenarios. For system integrators and OEMs, this processor provides a balanced combination of performance, connectivity, and scalability.

Technical Specifications

The BMXP3420102 offers substantial I/O handling capacity for demanding applications. In multi-rack configurations, it supports up to 1024 discrete I/O points and 256 analog I/O channels. For single-rack setups, it handles 704 discrete I/O and 66 analog I/O. Additionally, this processor manages up to 36 application-specific channels and supports motion control through CANopen.

Regarding memory, the BMXP3420102 includes 4MB of internal RAM, with 3584KB dedicated to program storage, constants, and symbols. It also provides 256KB for data storage. A supplied memory card (BMXRMS008MP) supports backup of programs, constants, symbols, and data for enhanced security.

Execution performance proves impressive for this class of controller. Boolean instructions execute in just 0.12 microseconds, while floating-point operations complete in 1.16 microseconds. Consequently, the processor delivers 8.1 Kinst/ms for 100% Boolean applications, ensuring responsive control for time-critical processes.

Communication Capabilities

The BMXP3420102 offers versatile built-in communication options. First, it includes non-isolated serial links supporting both RS232C and RS485 protocols. These ports handle Modbus RTU/ASCII and character mode communication at speeds from 0.3 to 19.2 kbit/s. Second, a USB port provides 12 Mbit/s connectivity for programming and diagnostics.

For fieldbus integration, this processor features a CANopen master bus through a SUB-D 9 connector. It supports transmission rates from 20 kbit/s up to 1 Mbit/s, with bus lengths reaching 2500 meters at lower speeds. Furthermore, the BMXP3420102 can address up to 63 CANopen server devices, making it suitable for distributed automation architectures.

Embedded communication services include Network Management (NMT), Process Data Objects (PDO), and Service Data Objects (SDO). Special functions like SYNC, EMCY, and TIME further enhance its CANopen capabilities.

Application Structure and Programming

The BMXP3420102 supports a comprehensive application structure. It features one cyclic or periodic master task, one periodic fast task, and up to 64 event tasks. This flexible task architecture allows you to prioritize critical control functions appropriately. The processor does not include an auxiliary task, simplifying the application model.

Programming efficiency benefits from the processor's fast instruction execution. The system overhead measures 0.7ms for the master task and 0.13ms for the fast task, ensuring minimal impact on overall cycle times.

Monitoring and Diagnostics

This processor includes comprehensive diagnostic capabilities. It features Modbus diagnostic counters and event counters for detailed performance monitoring. Status LEDs provide clear visual indication of system status. These include indicators for processor running (RUN), I/O faults (I/O), CAN bus status (CAN RUN and CAN ERR), memory card status (CARD ERR), processor faults (ERR), and Modbus activity (SER COM).

Environmental and Certification

The BMXP3420102 operates reliably within a temperature range of 0°C to 60°C. It supports relative humidity from 10% to 95% without condensation and carries an IP20 protection rating. This processor complies with numerous international standards, including EN 61131-2, EN/IEC 61010-2-201, and UL 61010-2-201.

Furthermore, it holds certifications from CE, UL, CSA, RCM, EAC, and Merchant Navy. It also meets hazardous location requirements for Class I Division 2 applications, expanding its suitability for challenging environments.

Installation and Setup

Installing the BMXP3420102 requires following standard Modicon M340 procedures. First, ensure the power supply is disconnected from the rack. Next, align the processor module with the designated slot on the M340 rack. Then, insert the module firmly until it seats properly in the backplane connector. After securing the module, connect your communication cables to the appropriate ports. Finally, apply power and verify the RUN LED illuminates, indicating normal operation.
