Schneider BMEH584040 Redundant Processor Module

BMEH584040 Modicon M580 Redundant Processor Module

Product Introduction

The BMEH584040 is a powerful redundant processor module built for the Modicon M580 automation platform. It delivers exceptional processing speed, executing 40 Kinstructions per millisecond for Boolean logic. Moreover, this module supports a Hot Standby (HSBY) configuration, ensuring seamless switchover during faults. It manages up to 16 remote I/O racks, accommodating both X80 and Quantum I/O drops. Additionally, the BMEH584040 offers extensive communication capabilities, including Ethernet TCP/IP and a dedicated HSBY port. Furthermore, it is Achilles certified, providing robust cybersecurity protection. This processor is ideal for water treatment, power generation, and oil and gas applications where downtime is unacceptable.

Processing Performance and Memory

The BMEH584040 excels in computational power and memory capacity. Its integrated RAM includes 16 MB for program storage and 2048 kB for data. Additionally, it features 10 kB of system memory for efficient task management. The module supports expandable flash storage up to 4 GB for data logging and firmware updates. This processor executes complex applications with ease. For mixed workloads (65% Boolean + 35% arithmetic), it processes 30 Kinst/ms. For purely Boolean logic, it achieves 40 Kinst/ms. Consequently, this high throughput ensures rapid scan cycles, even in demanding applications. The application structure includes a cyclic/periodic master task and a periodic fast task. This flexibility allows you to prioritize time-critical control loops.

Redundancy and High Availability

A standout feature of the BMEH584040 is its Hot Standby redundancy capability. Two identical processors can be configured in a primary/standby pair. The HSBY link, using a dedicated Ethernet port, synchronizes data between them. If the primary processor fails, the standby unit takes over instantly. This switchover is transparent to the connected I/O and networks. Specifically, the module includes two Ethernet TCP/IP ports for device networks, one service port, and one HSBY port. Additionally, the processor supports RIO and DIO scanner services. These manage remote and distributed I/O communication efficiently. Therefore, the BMEH584040 guarantees maximum system uptime.

Connectivity and I/O Capacity

The BMEH584040 supports a wide range of I/O and devices. It can manage up to 16 remote I/O stations, each containing X80 or Quantum drops. Furthermore, it handles 64 distributed equipment nodes and 61 Ethernet devices. For specialized applications, it supports HART, SSI encoder, serial link, and motion control. It also features accurate time stamping and counter functions. The module's integrated connection types include:

• 1 Ethernet TCP/IP service port

• 2 Ethernet TCP/IP device network ports

• 1 Ethernet HSBY port

• 1 USB type mini B port

Consequently, this processor serves as a central hub for complex automation architectures.

Cybersecurity Features

In today's connected world, security is paramount. The BMEH584040 is Achilles certified, verifying its resilience against cyberattacks. Additionally, it includes an embedded firewall and IPSec for secure network communication. It supports secure HTTPS communication and TLS (Transport Layer Security). The processor also features password protection, port hardening, and firmware signature verification. For auditing, it includes SNMP logging, Syslog protocol support, and a comprehensive security log. Audit trail functionality helps track system changes. Therefore, the BMEH584040 provides robust protection against unauthorized access and cyber threats.

Mechanical and Environmental Parameters

The BMEH584040 operates reliably in temperatures from 32 °F to 140 °F (0 °C to 60 °C). It can be stored between -40 °F and 185 °F (-40 °C to 85 °C). The module withstands vibration up to 3 gn and shocks up to 30 gn. Its relative humidity tolerance ranges from 5 % to 95 % at 131 °F (55 °C), without condensation. The processor has an IP20 protection rating, suitable for control cabinet installation. It operates at altitudes from 0 to 6561.68 feet (0 to 2000 meters), with derating up to 5000 meters. Compliance with low voltage and EMC directives ensures safe operation.

LED Diagnostics and Monitoring

The BMEH584040 features 13 diagnostic LEDs for rapid troubleshooting. These include:

• RUN (Green): Processor running

• ERR (Red): Processor or system fault

• I/O (Red): I/O module fault

• DL (Green): Download in progress

• BACKUP (Red): Memory card or CPU flash fault

• ETH MS (Green/Red): Ethernet configuration status

• Eth NS (Green/Red): Ethernet network status

• REMOTE RUN (Green): Peer processor running

• A (Green): Processor ID set to A

• B (Green): Processor ID set to B

• PRIM (Green): Acting as Primary

• STBY (Green): Acting as Standby

• FORCED IO (Green): I/O values overridden

• Hsby Diag (Green): Hot standby link status

Consequently, operators can quickly diagnose system status at a glance.

Installation Guidelines

Installing the BMEH584040 requires careful attention to redundancy configuration. First, power down the M580 rack completely. Insert the module into the designated CPU slot. Secure it with the retaining screws. For HSBY setups, install two processors in separate racks. Connect the HSBY Ethernet ports between them using a crossover or switch. Then, connect the device network ports to your plant network. After hardware installation, configure the processor using EcoStruxure™ Control Expert software. Set the primary/standby roles, IP addresses, and redundancy parameters. Upload your application program and download it to both processors. Finally, test the switchover function by simulating a fault on the primary unit. Verify that the standby takes over without process interruption.
