Schneider Electric BMEP581020 M580 Standalone Processor 4 MB

BMEP581020 M580 standalone processor with Ethernet backbone

The BMEP581020 is a Schneider Electric product listed in the datasheet as: standalone processor, Modicon M580, 4MB, 61 Ethernet devices, 4 local IO racks of 1024 digital, 256 analog [TAA]. The BMEP581020 is a standalone processor for the Modicon M580 ePAC platform. It runs control programs with an Ethernet-based backplane and scans local and remote I/O, and it has built-in cybersecurity services. Seven Star LLC supplies the BMEP581020 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: BME marks the M580 platform, P58 the standalone processor series, and the following digits the model in the series (the datasheet title: 4 MB, 61 Ethernet devices, 4 local I/O racks of 1024 digital, 256 analogue). The marking [TAA] in the datasheet title refers to a trade-agreement compliance version.

Technical specifications of the BMEP581020

Capacity, tasks and security of the BMEP581020

Racks: 4. Local I/O capacity: 256 I/O. Application-specific channels: 36. Distributed devices: 64. Memory: Integrated RAM, 4 MB program; Integrated RAM, 384 kB data; Expandable flash, 4 GB data storage; Integrated RAM, 10 kB system memory. Cybersecurity: DoS prevention; IPSec; SNMP logging; Syslog protocol support; Transport layer security; Audit trail; Embedded firewall; Firmware signature. Instruction speed: 30 Kinst/ms 65 % Boolean + 35 % fixed arithmetic; 40 Kinst/ms 100 % Boolean. Tasks: 1 periodic fast task; 2 auxiliary tasks; 1 cyclic/periodic master task; 64 event tasks.

The M580 differs from the M340 in that its backplane and its device network are both Ethernet, so I/O and communication modules share high bandwidth. A processor of this class is a good fit for a process unit with many analogue loops and a requirement for secure remote access.

Racks, power and companion modules of the BMEP581020

The processor sits in the first slots of an M580-compatible rack such as BMEXBP0800 together with a rack power supply (for example the BMXCPS family). Remote I/O drops and distributed devices connect through the Ethernet service ports of the processor and communication modules.

Programming software and firmware must be in step: an M580 firmware version determines which communication and security features are enabled. Always record the version when ordering spares.

Selection checklist for the BMEP581020

• I/O and loop count against the processor capacity.
• Number of remote drops and distributed devices.
• Memory: 4 MB program capacity.
• Cybersecurity features required on site and certificates.
• Redundancy needs, for which a BMEH58 processor is used instead.
• Rack and power supply compatibility.

Commissioning, backup and spares for the BMEP581020

Insert the processor into the first slot positions of the rack, power the rack, and connect Ethernet to the network on the service port. Set the IP address with the engineering software and download the program and the configuration.

Keep a stored copy of the application and of the firmware, and keep a spare processor with the same firmware level for critical plants. The Ethernet traffic should be on a managed switch with the network design from the system guide.

Typical applications of the BMEP581020 in Oman and the GCC

In Oman and the GCC the M580 appears on water-treatment plants, power-distribution automation and oil and gas utility packages where a high-availability, secure PLC is specified. Plant cybersecurity policies often decide the choice between the M580 and older M340 racks.
