System compatibility

XVME-402 belongs to XYCOM XVME series fieldbus communication controller module.

It installs in XYCOM VME chassis and cooperates with XVME series CPU and 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 communication bridge between VME main bus and Bitbus distributed remote I/O subnet.

Onboard i80C152 processor handles Bitbus protocol stack independently,offload communication task from VME host CPU.

Realize data exchange between VME rack and multiple Bitbus remote I/O nodes.

Support read and write operations to remote Bitbus I/O modules,collect field discrete and analog signals.

Support hardware interrupt to notify host CPU once remote data update or fault occurs.

Transmit field I/O data and control commands between VME backplane and Bitbus field subnet.

Onboard self-test for Bitbus controller,communication transceiver,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-402 card into empty single-height VME slot,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Connect Bitbus twisted pair field cable to front panel connector.

Power on chassis,run hardware self-test.

VME CPU scans bus,identifies the board and starts Bitbus distributed I/O communication.

Interface

VME P1 backplane connector,front panel Bitbus field wiring terminal,LED indicators:PASS,FAULT.

Feature

Single height VME Bitbus master controller board,XYCOM XVME series.

Independent i80C152 processor,real-time Bitbus protocol processing.

Build distributed remote I/O network to expand system I/O capacity over long distance.

Twisted pair bus wiring,suppress industrial field electromagnetic interference.

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:Bitbus controller damage or VME bus communication failure;

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

Bitbus remote node offline:check field twisted pair wiring,bus termination resistor and remote station power;

Intermittent communication dropout:check cable shielding and grounding condition.

Product Brief

XYCOM XVME-402 is legacy VMEbus Bitbus master controller module.

It serves as gateway connecting VME system and Bitbus distributed I/O subnet,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
