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.

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.

KEY FEATURES AND BENEFITS • VibroSight ® compatible hardware from the vibro-meter ® product line • Communications interfaces for industry standard fieldbuses: Modbus RTU, Modbus TCP, PROFIBUS DP and GOOSE (IEC 61850) • PROFIsafe safety layer to ensure more reliable and secure PROFIBUS DP communications • Two VSI010 modules per VibroSmart measurement block allows redundant operation • AND, OR and majority voting logic functions for the combination of alarm and status information for a VibroSmart measurement block • VibroSmart ® security (module lock) • Redundant communications and redundant power supply inputs to improve availability • Discrete outputs: 2 local relays • Real-time Ethernet communications • Live insertion and removal of modules (hot swappable) with automatic reconfiguration • Fully software configurable • Robust enclosures with DIN rail mounting APPLICATIONS • Communications bridge between a VibroSmart system and third-party systems, such as a DCS or PLC • Machinery protection and/or condition monitoring • Conforms to IEC 61850-3 requirements for power plant and utility applications

Applications information

VSA003 BNC cable assemblies are typically used

with VSA004 BNC patch panels in order to make

the buffered “raw” outputs from VSV30x + VSB300

monitoring modules readily available via BNC

connectors in a rack, panel or other permanent

enclosure.

As each populated VSA004 BNC patch panel slot

uses a VSA003 BNC cable assembly to connect to

a VSV30x + VSB300 module, one VSA003 is

automatically included for each populated

panel slot in an order, although they can also be

ordered separately.

For specific applications and other information,

contact your local Meggitt representative.

The VSA004 BNC patch panel is a DIN-rail

mounting device, making it suitable for industrial

environments where equipment must be installed

on DIN rails. Its compact dimensions also allow it

to be deployed within an industrial housing with a

particular IP or NEMA rating, in order to provide

environmental protection.

VSA004 BNC patch panel

The VSA004 BNC patch panel is designed to

provide a permanently installed patch panel that

makes the buffered outputs from

VSV30x + VSB300 monitoring modules available

via BNC connectors in a rack, panel or other

enclosure.

The VSA004 is a robust aluminium enclosure with a

standard height of 2U (HE). It provides 10

individual slots with a standard width of 4 TE that

can be populated with either a blank slot panel

or a populated slot panel with cutouts for three

BNC connectors (female), corresponding to the

buffered “raw” outputs of a VSV30x + VSB300

module. That is, the RAW CH1, RAW CH2 and

RAW AUX signals.

VSA003 BNC cable assembly

The VSA003 BNC cable assembly is designed to

connect the buffered sensor “raw” outputs

available from VSV30x + VSB300 monitoring

modules to other systems.

The VSA003 uses a 2 m long cable, one end of

which is terminated with flying leads crimped with

wire-end ferrules for easy connection to a

VSV30x + VSB300 module (via the terminal base’s

J2 connector). The other end of the cable is

terminated with female BNC connectors for use

with patch panels such as the VSA004 BNC patch panel.
