VMIC VMIVME-7452 Eurocard IDE Storage Module

Module Feature

VMIVME-7452 is a single-slot 6U VMEbus storage module developed by VMIC (GE Fanuc / Abaco Systems). It adopts integrated mechanical carrier design inside standard 6U VME card frame,supports installation of 2.5 inch IDE hard disk and 3.5 inch floppy disk drive. The carrier comes with shock damping structure to protect mechanical disk media under industrial vibration environment. The board works as VME slave device and communicates with VME single board computer via VME bus. Front panel is fitted with disk eject opening and activity LED indicator. Onboard FPGA converts VME bus protocol to standard IDE ATAPI control signals. Built-in BIT diagnostic continuously monitors drive power supply,media presence and read/write error events;fault status can be read through VME control register. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine VME control chassis local historical data storage,aerospace ground test bench and hardware-in-loop real-time simulation VME chassis.

Working principle

VME host controller sends IDE read/write commands to VMIVME-7452 over VME bus. Onboard VME interface FPGA converts VME bus address and data signals into IDE control signals to operate the hard disk and floppy drive. Disk data is temporarily cached and transmitted back to VME CPU. BIT circuit monitors disk power rail,media detection and access errors in real time,refreshing activity LED and fault status register accordingly.
