Mechanical Data

‑ Weight：approx 0.42 kg ‑ Dimension：Series‑90‑70 standard single‑slot plug‑in module form‑factor ‑ Handling note：ESD‑sensitive high‑speed memory circuit, anti‑static wrist‑strap mandatory during handling ‑ Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Provide large‑capacity dual‑port buffer memory for Genius bus controller IC687BEM711, enhance data exchange capacity between Series‑90‑70 CPU and Genius remote I/O blocks.
2. Cache cyclic global‑data, acyclic datagram messages and slave block fault diagnostic information, reduce CPU load of processing Genius bus data.
3. Revision‑B hardware is backward‑compatible, can directly replace IC687BEM713A without hardware modification.
4. LED status indication:   ‑ Green OK：Module power‑on and self‑test pass   ‑ ACT：Genius‑bus data access activity indicator

Installation & Wiring Requirements

1. Cut off Series‑90‑70 PLC rack power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling module.
2. Insert IC687BEM713B fully into PLC backplane slot and lock latch; confirm matching with IC687BEM711 Genius controller module.
3. Genius‑bus wiring strictly follow GE Genius hardware manual; use shielded twisted‑pair bus cable; install terminating resistor at both physical ends of bus trunk; separate signal cables 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 PLC, verify OK & ACT LED status, download Genius hardware configuration, perform bus‑scan and full I/O‑loop commissioning test.
6. Replacement note: Verify CPU firmware compatibility; full Genius‑bus‑loop simulation test mandatory before unit put‑into‑service.
