10. Board Control System nvSRAM type: PowerStore 32Kx8 Board Control Systems are essential parts of modern vehicles, e.g. for large excavators. They are remarkable for their extraordinary performance and combine proven engineering with advanced technological developments. Many technological refinements have been incorporated to reduce maintenance and to lower operating costs. These include for instance the integrated electronic system. 9 Bansuk industrial

11. The Board Control System(BCS) • High-performance 32-bit monitoring and data logging system for vital signs and service data of the engines, hydraulic system, pumps, motors and drive system. • All essential operational data, errors as well as limits are displayed (analog & digital) on the monitor of the control column. • Any irregularities are immediately indicated optically & acoustically so that serious damage can be prevented well in advance. 10 Bansuk industrial

12. 보다 작고 보다 능률적인 발자국 SDRAM 베터리의 필요를 제거하고, Journal 보호와 실행(Performance)을 허용하는 Write를 지속적으로 제공 SKU 의 유연성 같은 발자국 안에 복합적인 SKUs 와 firmware 구조를 제공할 수 있다. (Battery-backed write and read cache와 함께또는 없이도) Performance 향상 Read/write cache data 와 write journal 사이의 대역폭(전송용량) 경합(복수의 단말이 공유하는 회로에서 동시에 송신할 때 생기는 상태)의 제거 빠른 mirroring operations 허용. 승인(acknowledging)완료 전에 Second Disk로 Write를 완료까지 기다릴 필요가 없다. 높은 신뢰성 72시간 이상 Write journal data 를 지속할 수 있다. 간단한 디자인 DRAM 이 Deep sleep 모드로 있는 동안 개발을 위해 재생(Refresh) and recall algorithms 을 하지 않는다. RoHS Compliant 와개선된 제조 다루기 위한 Batteries가 없음 Battery SDRAM을 넘은 nvSRAM의 장점 11 Bansuk industrial
