System compatibility

XVME-957 belongs to XYCOM XVME series intelligent communication module.

It can cooperate with XVME series VME CPU boards.

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

Intelligent serial communication controller for VME system.

Offload serial data processing burden from main CPU,onboard processor handles frame assembly,CRC check and timeout retransmission.

Each serial channel can be independently configured as RS232/RS422/RS485.

Adopt shared memory mode to realize high-speed data interaction between main CPU and serial board.

Support asynchronous and HDLC synchronous serial communication.

Trigger VME interrupt when receiving complete data frame or alarm event.

Support self-test for communication channel,fault state displayed via LED indicator.

Installation

Power off VME chassis.

Insert XVME-957 card into empty 6U single-height VME slot,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Connect serial field wiring on front panel.

Power on chassis,run hardware self-test with VME host CPU board.

Interface

VME P1,P2 backplane connector,multi-channel serial terminal/DB port,LED indicators and reset switch.

Feature

6U single slot VME intelligent serial board,XYCOM XVME series.

Onboard local processor to reduce main CPU load.

Multi-channel independent configurable serial interface,support multiple electrical standards.

Built-in FIFO buffer to improve data throughput and prevent data loss.

Shared memory data exchange mechanism,stable communication in noisy industrial environment.

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

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

LED alarm on:channel communication error,address jumper error,bus fault or power supply abnormality;

Serial device no communication:check wiring,serial parameter matching(baud rate,parity,data bit);

VME communication failure:check backplane contact and address configuration.

Product Brief

XYCOM XVME-957 is legacy VMEbus 6U intelligent multi-channel serial communication controller.

It offloads serial protocol processing for VME host,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
