System compatibility

70688-001 VME-AT belongs to XYCOM XVME series VME CPU board.

It serves as main controller of VME chassis and cooperates with XVME series I/O modules.

Compatible with 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

Act as the main processor unit of VME control rack,run PC/AT compatible industrial control operating system.

Manage VME bus arbitration,read and write data of each I/O module inside chassis.

Process analog and discrete field signals,execute closed-loop control and safety interlock logic.

VGA interface supports display output for on-site monitoring and system debugging.

IDE and floppy controller support local storage for firmware and control program.

Dual RS232 serial ports,parallel port and PS/2 keyboard/mouse interface for peripheral connection.

Onboard speaker for system alarm and status prompt.

Onboard self-test for CPU,memory,storage interface and VME bus hardware fault inspection.

Support 7-level VME bus interrupt for fast event response.

Installation

Power off VME chassis.

Insert 70688-001 VME-AT card into empty 6U VME slot,tighten front panel fixing screw.

Connect serial cable,VGA display,PS/2 keyboard and storage device as required.

Power on chassis,complete boot sequence and run hardware self-test.

Scan VME backplane to identify all I/O modules,load control software.

Interface

VME P1/P2 backplane connector,front VGA port,PS/2 keyboard/mouse port,dual RS232 serial port,parallel port,speaker interface,LED indicators:PASS,FAIL.

Feature

Single height 6U VME standard board,PC/AT compatible architecture,easy replacement in VME rack.

Intel 80486SLC/e low power industrial processor,suitable for legacy real-time control applications.

Integrated VGA,IDE,floppy,audio and multi I/O ports,reduce auxiliary hardware requirement.

Optional math coprocessor for complex process calculation.

Support VME master/slave and multi-level interrupt,stable data exchange with I/O boards.

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

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

FAIL LED on:memory fault,CPU failure or poor backplane contact;

System boot failure:check DRAM,storage media and VME backplane power;

VGA/serial abnormal:check front panel wiring and peripheral hardware;

Cannot communicate with I/O modules:check VME bus arbitration and address mapping.
