ABB DSMC112 57360001-HC Floppy Disk Controller Board

Description

Hardware and Performance Specifications Auxiliary supply: Powered by VME rack back‑plane, no external power supply required Power consumption: ≤7 W External device interface: Floppy disk drive interface Core function: Floppy disk read‑write control, program/configuration backup‑restore Mounting mode: VME Eurocard plug‑in board for Advant subrack Protection class: IP20 Operating temperature: −20 ℃ ~ +70 ℃ Storage temperature: −40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial electromagnetic‑compatibility standards Dimension & weight: approx. 324 × 234 × 22.5 mm, weight approx. 0.40 kg Certifications: CE approval

Main Functions Realize hardware interface driving between Advant AC400 controller and external floppy disk unit. Support reading and writing system configuration, user application programs and process parameters on floppy disk media. Complete system backup and configuration restoration via floppy disk for on‑site maintenance work. Front‑panel LED indicators display power‑on status, drive activity and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and floppy‑drive communication errors, and reports fault information to the main controller. Parameter configuration and peripheral drive debugging are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Floppy‑drive connecting cables shall adopt shielded twisted‑pair and be strictly separated from high‑power power cables. Ensure reliable cabinet protective grounding. After module replacement, confirm full part‑number DSMC112 / 57360001‑HC matches original project configuration. Perform read‑write test with matched floppy drive and verify backup‑restore function. Different hardware revisions cannot be directly interchanged without configuration adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Floppy‑disk‑controller‑board spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for legacy DCS system program backup, parameter restore and firmware upgrade in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.

Key Features

1. Dedicated floppy disk controller for legacy Advant AC400 DCS systems, implements removable media data access for old‑generation DCS.
2. Standard VME Eurocard design, back‑plane powered, convenient for on‑site replacement and maintenance.
3. Supports system configuration backup and restore, facilitates spare‑part replacement and system commissioning.
4. Built‑in hardware and peripheral‑interface diagnosis function, convenient for fault location.
5. Strict full‑part‑number matching required for spare‑part replacement.
