Schneider Electric BMEP58CPROS3 Modicon M580 Safety CoProcessor

Configured for safety processing between the Modicon M580 Safety processor and rack-based control architecture, the Schneider Electric BMEP58CPROS3 (BMEP58CPROS3 Safety CoProcessor) provides direct processor-level execution through the internal rack power and backplane interface. It is a coated processor module with SIL 3 capability, IP20 protection, and Modicon X80 compatibility.

Hardware Specifications

M580 Safety Processor and Backplane Integration

BMEP58CPROS3 is installed in the Modicon M580 rack next to the M580 Safety processor. The module receives its operating power through the rack and interfaces with the rack architecture rather than using a separate field power input.

The specified installation requires the CoProcessor to be mounted adjacent to the CPU and secured with two screws at the top of the module. Modicon X80 I/O, backplane and cable components can be used within the supported M580 architecture.

The module provides status indication through RUN, ERR, DL, SRUN and SMOD LEDs for processor operation, fault status, download activity, safety mode and maintenance mode.

Safety and Environmental Characteristics

The module is specified for SIL 3 and PL = e applications and uses conformal coating for environmental protection. Environmental specifications include IP20 protection, 3 gn vibration resistance and 15 gn shock resistance.

The published environmental characteristics include gas resistance class Gx under ISA S71.04, gas resistance class 3C4 and dust and sand resistance class 3S4 under IEC 60721-3-3. ATEX and IECEx Zone 2/22 certifications are also specified.

Frequently Asked Questions

Q: Does BMEP58CPROS3 require a separate power supply?

A: No. The module receives its operating power internally through the Modicon M580 rack. The specified current consumption is 295 mA at 24 VDC.

Q: Where should the BMEP58CPROS3 be installed in the rack?

A: The CoProcessor must be installed in the rack next to the M580 Safety processor and secured using the specified two top mounting screws.

Q: Which software is specified for configuration and programming?

A: The module operates within the Modicon M580 architecture using EcoStruxure Control Expert.

Field Installation Guidelines

• Verify that the rack, M580 Safety processor and associated X80 components are compatible before installation.
• Install the BMEP58CPROS3 directly next to the M580 Safety processor as specified by the product documentation.
• Secure the module mechanically with the designated mounting screws before energizing the rack.
• Keep the module within the specified -25 to 60 deg C operating temperature range.
• Maintain the required environmental conditions for humidity, vibration, shock and altitude.
• Do not obstruct the module ventilation area or exceed the IP20 installation environment.
• Follow the applicable cabinet grounding and EMC practices for the complete M580 installation.
• Route power and communication wiring according to the system installation documentation and maintain physical separation from high-noise power circuits where required.
• Confirm the RUN, ERR, DL, SRUN and SMOD indicators after installation and during commissioning.
