Working Principle: After power‑on, module loads and runs B&R Automation‑Runtime real‑time‑operating‑system. Execute user control‑program stored in FlashPROM. Realize I/O‑data exchange via back‑plane‑bus with each I/O‑module. Complete data‑interaction with HMI and external‑equipment via RS232 or expansion‑card interface, finish logic‑calculation, closed‑loop‑control and motion‑control task of automation equipment.

Installation Requirements:

• Insert into designated CPU‑slot position of B&R 3BP‑series back‑plane‑rack
• Ensure back‑plane‑connector fully engaged and module‑lock‑clip locked
• Install matching backup‑battery for real‑time‑clock and data‑retention
• Complete hardware‑configuration and user‑program download before commissioning
