Description
1. Product Overview
Abaco Systems VMIVME‑7452 is a standard 6U single‑slot VME bus storage expansion module. Originally a classic industrial control storage unit manufactured by VMIC, it is now part of Abaco Systems embedded computing product line. Designed for VME/VME64x bus‑based embedded industrial control systems, military airborne equipment, industrial measurement‑and‑control platforms and real‑time data acquisition systems, this module provides disk storage expansion, local data caching, system program mounting and on‑site data persistent storage for VME single‑board host computers. It serves as an indispensable auxiliary storage peripheral for VME‑architecture measurement‑and‑control systems.
Adopting passive bus architecture and low‑power industrial‑grade design, the VMIVME‑7452 occupies one standard 6U VME slot. It supports optional storage media including floppy disk, mechanical hard disk, solid‑state drive and FLASH memory. It delivers large‑capacity local storage expansion without consuming main controller resources. Featuring wide‑temperature operation, vibration resistance, reliable data read‑write performance and error correction capability, the module fits harsh operating conditions in aviation, military industry, rail transit and high‑end industrial measurement‑and‑control fields. Widely deployed in maintenance replacement, embedded platform storage capacity expansion and technical retrofit of legacy VME systems, it acts as an original core storage spare part for industrial and military embedded VME systems.
2. Functional Features
Standard VME Bus Compatibility for Plug‑and‑Play Expansion Fully compliant with VME64x industrial bus protocol, it adopts standard 6U single‑slot form factor and passive bus connection design. It only draws power, ground and P2 user‑defined pin resources from the VME backplane, without consuming main controller bus bandwidth or interfering with real‑time system operation. It is directly compatible with all VME‑architecture main control boards, enables in‑situ storage expansion with no modification to system architecture, and fits all standard VME industrial control chassis and embedded platforms.
Multi‑Media Storage Compatibility with Flexible Configuration The module supports optional multiple storage media. It is factory‑equipped with a 3.5‑inch 1.44 MB floppy disk drive, with IDE/SATA HDD, SATA SSD and FLASH memory module as alternatives. Different capacity and reliability storage solutions can be configured according to operating‑condition requirements to satisfy multi‑scenario demands including program solidification, log archiving and real‑time on‑site data recording.
Low‑Power Passive Design with Minimum System Overhead Built upon passive hardware architecture without complex computing chips or high‑power‑consumption components, the module achieves extremely low power consumption in standby and operating states. It imposes no extra load on the VME host system and does not compromise real‑time response. No heat accumulation or power drift occurs during long‑term continuous operation, meeting low‑power and high‑reliability requirements for embedded systems.
Industrial‑Grade Wide‑Temperature Operation for Harsh Environments Constructed with full industrial‑grade components and reinforced mechanical design, it supports an ultra‑wide operating temperature range of ‑40℃ ~ +85℃. It withstands alternating high‑low temperature, heavy vibration, dust‑humidity and complex electromagnetic interference, perfectly fitting high‑reliability scenarios such as airborne, vehicle‑mounted and field measurement‑and‑control applications, and eliminating storage read‑write anomalies and data loss induced by temperature fluctuation.
Built‑in Data Error Correction and Protection for High‑Storage Reliability Integrated hardware data checksum, error detection and fault‑tolerant read‑write logic automatically identifies and corrects read‑write exceptions and bit errors. It effectively prevents data corruption, file loss and abnormal program loading caused by industrial electromagnetic interference and voltage fluctuation, and guarantees integrity of system programs, configuration parameters and field acquired data.
Standardized Embedded Adaptation with Excellent System Compatibility Natively compatible with VxWorks, Linux and other embedded real‑time industrial operating systems, it comes with mature drivers and high protocol compatibility. It directly mounts system images, application programs, configuration files and historical data, adapting to various embedded software ecosystems for military, aviation and industrial measurement‑and‑control applications. Legacy VME equipment replacement requires no driver adaptation or system reconstruction.
- Reinforced Anti‑Vibration Structure against Industrial Mechanical Shock Modular reinforced packaging with mechanically locked components and strengthened solder joints tolerates long‑term equipment vibration, start‑stop shock and transportation jolt. It prevents loose storage media, read‑write interruption and hardware desoldering, suitable for high‑vibration conditions of mobile devices, high‑speed operating equipment and field airborne units.
