Meggitt VibroSmart ® VSI010 + VSB010 communications interface module

Introduction

The VibroSmart ® distributed monitoring system

(DMS) is a system of modular and scalable

products designed for condition monitoring and

machinery protection applications for power

generation turbines, oil and gas applications and

auxiliary balance-of-plant equipment.

VibroSmart ® modules can be mounted directly

on machinery, reducing the need for expensive

cabling, because they are designed and certified

to work in extremes, such as harsh industrial

environments characterised by potentially

explosive atmospheres (Ex Zone 2), high

temperatures (70 °C, 158 °F) and high mechanical

stress. VibroSmart complements the VM600 series

of rack-based solutions from Meggitt’s

vibro-meter ® product line and is compatible with

the same VibroSight ® machinery monitoring

system software.

The VibroSmart ® VSI010 communications

interface module is an optional communications

module for use with other VibroSmart modules in a

monitoring system. The VSI010 module supports up

to two fieldbus channels and allows the data from

the VibroSmart modules in a measurement block

to be read by fieldbus master devices.

VibroSmart distributed monitoring system

A VibroSmart ® distributed monitoring system

(DMS) is a network of small and economical

modules providing measurement,

communications or other functions that are

connected together in distributed, networked

measurement blocks in order to provide the

functionality normally offered by rack-based

machinery monitoring systems. A VibroSmart

system consists of one or more measurement

blocks, each containing up to sixteen VibroSmart

modules, a power supply and an optional host

computer running the VibroSight software.

A measurement block is a logical grouping of

VibroSmart modules that allows data such as

tachometer, trigger and alarm information to be

shared, for example, in order to monitor the same

machine. Measurement blocks are configured

using the VibroSight software.

Note: A VibroSmart system is limited to a

maximum of two VSI010 modules per

measurement block.

A VibroSmart module consists of an electronics

module (providing configurable machinery

monitoring functions) that clips into a VibroSmart

terminal base, which mounts on a DIN rail. A

range of plug-in fieldbus communications

adaptors that interface directly with the VSI010

module are available to provide an integrated

solution for interfacing to fieldbuses.

VibroSmart terminal bases incorporate buses and

connectors to provide all of the I/O connections

required to interface to a VibroSmart module.

Terminal bases also include non-volatile memory

to store the configuration of the attached

VibroSmart module, which allows modules to be

hot-swapped. Modules and terminal bases use

mechanical key-coding for a system that is simple

to operate and use.

Different VibroSmart modules, terminal bases and

fieldbus communications adaptors can be

combined to offer unique combinations of

functionality, versatility and safety assurance. In

this way, a monitoring system can be built to meet

the exact needs of an application resulting in a

more cost-effective and reliable solution.
