System compatibility

XVME-113 belongs to XYCOM XVME series large capacity memory module.

It installs in XYCOM VME chassis and cooperates with XVME series CPU and I/O modules.

Compatible with 8/16/32-bit VME processor boards,turbine,compressor and legacy DCS control systems via VME bus.

Commonly used for power plant,oil & gas,petrochemical old equipment maintenance and spare replacement.

Function

High capacity storage expansion for XVME VME controller rack.

Supports RAM,EPROM,Flash,EEPROM multiple memory media to store control program,firmware and process data.

Onboard battery backup and real-time clock RTC,realize data preservation and time record when power failure.

Two independent memory banks,support jumper configuration for address,memory type and speed.

Support RMW read-modify-write and UAT unaligned transfer,VME A24/A32 addressing.

Onboard self-test for memory chip,battery monitoring circuit,RTC and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-113 card into empty double-height VME slot,tighten front panel fixing screw.

Set memory bank jumpers and switches according to actual configuration.

Power on chassis,run hardware self-test.

Controller identifies memory module and activate expanded memory space.

Interface

VME P1 backplane connector,LED indicators:PASS,FAULT,BATTERY LOW.

Feature

Double height VME large-capacity memory board,XYCOM XVME series.

24 memory sockets,two independently configurable memory banks.

Built-in real-time clock and battery low voltage monitoring alarm function.

Power-down protection circuit,prevent abnormal writing when voltage drops below 4.65V.

Industrial grade memory chip,stable data storage under vibration environment.

VME slave interface,easy plug-in installation.

Discontinued obsolete VME module,supply only for old production system spare replacement.

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

FAULT LED on:memory chip damage or VME bus communication failure;

BATTERY LOW LED on:backup battery voltage insufficient,need battery replacement;

Cannot be identified by CPU:check VME backplane contact and address jumper setting;

Data loss after power off or RTC time reset:check backup battery and battery circuit.
