Main Functions

1. Acts as Genius‑bus master controller, manages bus scheduling, token passing and all connected Genius remote I/O slave blocks.
2. Dual‑port shared RAM realizes high‑speed bidirectional data exchange between host CPU and Genius field‑bus I/O.
3. Supports multiple communication services: cyclic global‑data broadcast, acyclic datagram message and directed control data for parameter download.
4. Collects comprehensive bus diagnostic counters and slave‑block fault status, reports to host system.
5. On‑board hardware watchdog; jumper configurable auto‑restart mode when watchdog expires.
6. LED status indication (LEDs located on PCIM carrier):   ‑ Green OK：µGENI board self‑test pass   ‑ COMM：Genius‑bus communication activity indicator   ‑ FAULT：Bus error / slave fault alarm

Installation & Wiring Requirements

1. Cut off PCIM rack power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling daughter‑board.
2. Insert IC660ELB912 firmly onto PCIM carrier board; set baud‑rate jumpers consistent with all Genius slave blocks.
3. Genius‑bus wiring strictly follow GE Genius hardware manual; use shielded twisted‑pair bus cable; install bus terminator resistor at both physical ends of bus trunk; separate bus cable from high‑power cables, connect shielding to dedicated protective ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement：power‑on step‑by‑step, verify OK LED status, download Genius‑bus configuration, perform bus‑scan and full I/O‑loop commissioning test.
6. Replacement note: Verify PCIM hardware and firmware compatibility; full Genius‑bus‑loop simulation test mandatory before unit put‑into‑service.
