FAQs

Q1: What is the primary function of the BMEH586040?
A: It serves as a Level 6 Hot Standby redundant processor for Modicon M580 ePAC systems, executing control logic, managing local and remote I/O, and ensuring continuous operation through automatic failover in high-availability applications where downtime cannot be tolerated.

Q2: How does the Hot Standby redundancy work?
A: Two identical BMEH586040 processors are configured as Primary and Standby, synchronized via a dedicated HSBY Ethernet port. The Primary updates the Standby at the beginning of each scan. If the Primary stops communicating, the Standby assumes control within one scan, ensuring seamless operation.

Q3: What is the difference between BMEH586040 and BMEH586040S?
A: The BMEH586040 is a standard redundant processor for process control. The BMEH586040S adds SIL 3 safety certification for safety instrumented systems (SIS), with dedicated safety memory partitions and dual code execution for safety-related logic.

Q4: What cybersecurity features does this processor include?
A: The BMEH586040 is Achilles certified and includes DoS prevention, IPSec, SNMP logging, Syslog protocol support, embedded firewall, firmware signature verification, password protection, port hardening, secure HTTPS communication, audit trail, and security log.

Q5: What is the program and data memory capacity?
A: The BMEH586040 features 64 MB of integrated RAM shared between program and data storage, with a maximum combined capacity of 64 MB. It also includes 4096 kB of dedicated HSBY data memory for synchronization between Primary and Standby controllers.
