System compatibility

70630-025 XVME-630 belongs to XYCOM XVME series VME CPU board.

It serves as the 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,execute real-time industrial control programs.

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

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

Dual serial ports for system debugging,firmware download and external device communication.

Battery backed RTC keeps system time and small volume configuration data when power off.

Onboard self-test for CPU,memory,serial port and bus hardware fault inspection.

Support optional floating-point coprocessor for complex algorithm calculation.

Installation

Power off VME chassis.

Insert 70630-025 XVME-630 card into empty 6U VME slot,tighten front panel fixing screw.

Connect serial debug cable to front panel serial connector.

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

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

Interface

VME P1/P2 backplane connector,front dual serial port,LED indicators:PASS,FAIL,HALT.

Feature

Single height 6U VME standard board,easy installation and replacement in VME rack.

Motorola 68EC030 32-bit industrial processor,support real-time operating system.

Configurable memory banks,support SRAM/EPROM/Flash mixed combination.

Optional hardware floating-point coprocessor,suitable for complex process calculation.

Battery backup RTC and nonvolatile RAM,save system configuration parameters.

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

Vibration resistant PCB design,suitable for turbine and compressor control cabinet.

Diagnostic

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

System boot failure:check EPROM firmware integrity and VME backplane power;

Serial communication abnormal:check serial wiring,baud rate and communication protocol setting;

Cannot access I/O modules:check VME bus arbitration and address configuration.

Product Brief

XYCOM 70630-025 XVME-630 is legacy 6U single height VMEbus processor module based on 68EC030 CPU.

It executes control logic and communicates with all I/O modules in VME rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
