VibroSmart® – new VSV30x firmwareSummary of new features and benefits

VSV30x monitoring module firmware version 18 (PNR 642-001-000-018) brings some notable new features and benefits:

1. Module lock mode via spare DSI (multi-purpose): The VSV30x module can now be locked (prevent unauthorized configuration change) by connecting to ground the spare multi-purpose DSI (Discrete Input).

2. PTP time synchronization: for improved accuracy with up to sub-millisecond waveform synchronization between modules and improved VibroSight display of waveforms time.

3. Channel bypass: It is now possible to easily bypass a sensor connected to a VSV30x module via the VibroSight Scope client. By bypassing a sensor, all associated sensor OK status, alarm, danger and flags are ignored. The measured value is still being displayed to help for troubleshooting.

4. Support for pre-logging / pre-trigger : The VSV30x module supports now pre-trigger data logging in the Alarm Event based data logging rule (acquisition at higher rate).


VibroSmart® –new VSV30x firmwareImprovements and bug fixes

o Narrow band vibration for AC coupled input channels: NB vibration processing is now allowed for AC coupled dynamic input channels. In previous VibroSight versions AC+DC coupling was enforced by a configuration consistency check. As a resultof this change it is now possible to perform both a narrow band vibration processing and an asynchronous absolute bearing vibration processing using the same input channel with bearing absolute sensor (accelerometers and velocity sensors). Note that the flexible input channel to processing block mapping has been introduced with previous version -017 of VSV30x firmware.

o Direct waveform modification for Hydro applications: this is to correct intermittent mis-detection of generator pole with air-gap measurement. The module can now provide all tacho time stamps to VibroSight so for example all one-per-rev pulse for phase reference associated time stamp. The display is not yet available but will be with VibroSight 5.1.

PTP time synchronization1.2

New Features


VibroSmart® –new VSV30x firmwareNew feature PTP time synchronization

Both NTP (Network Time Protocol) and PTP (Precision Time Protocol) time servers use network time protocols to serve time to other devices on the network and achieve time synchronization between devices.

Firmware release prior 642-001-000-018 only provided NTP synchronization between the VibroSmart devices and other systems. The PTP synchronisation was only performed within a VibroSmart measurement block and for data exchange between modules. With FW -018 it is now possible to synchronize the VSV30X modules time to either a NTP or a PTP server for the timestamping of measurements provided to VibroSight.

With NTP synchronisation, the VSV30x modules were able to achieve time synchronisation between 2 – 10ms and in some cases up to 50ms.

With PTP, the VSV30x can synchronise waveform measurement to sub-millisecond in order to correlate events in VIbroSight from VibroSmart system with other systems such as disjonctors or electrical events and allow accurate analysis (accurate sequencing of events by comparing waveforms). Also VibroSight waveform plot display related to time axis and the option “Elapsed time” or “Time” have been improved to allow accurate time synchronization when comparing waveforms from different VibroSmart measurement channels.

VibroSmart® –new VSV30x firmwareNew feature PTP time synchronization – Delay Machanism selection

In VibroSight configurator, there is the option to choose the delaymechanism for the PTP synchronisation:

E2E = End-to-end

P2P = Peer-to-peer

Which one to choose? …of course, it depends. The short answer is thatthe P2P peer-to-peer delay measurement mechanism is best in anengineered network, where all switches (and routers if there are any)can be guaranteed to be 1588 capable, i.e. they are eithertransparent clocks or boundary clocks. If there are going to be anynon-1588 aware switches, or if there is any doubt about this, then youwant the E2E end-to-end delay measurement mechanism.

“Elapsed time” display mode example: the waveforms are synchronized using relative time from the start of their acquisition.

Channel bypass1.3

New Features


VibroSmart® –new VSV30x firmwareNew feature Channel bypass

Customer feedbacks were the trigger of this new feature. Prior FW -018, it was only possible to perform an “Alarm Bypass”of an entire VSV30x module by using VibroSight Scope or the “AB” DSI. There was no simple and efficient way to bypassone single channel. If the input channel or the processing block was set as “disabled” for example, many consistencychecks of the configuration were blocking the activation to the modules (i.e : Logic error, Modbus register error, DCoutput error, Dual channel error etc). With the new “Channel bypass” feature, it only takes few clicks to completelyignore a channel.

When “Channel bypass” is active:

The sensor OK associated with the input is forced to OK state

All flags as well from processing and alarms are forced to OK

The sensor power supply remains ON or as it is configured

A flag is indicating that the channel is bypassed, this flag is available for mapping to Fieldbus via the VSI010 module

When a speed is bypassed, if it is shared with another module, then the information is propagated and the processing using this speed will be bypassed as well

The calculated value is still displayed which is very useful for troubleshooting purposes


VibroSmart® –new VSV30x firmwareNew feature Channel bypass – VS Scope

To activate a channel bypass, use VibroSight Scope, (directconnect to device, not via a server) select the module and thenclick on the DSI command needed.

Note: on the screenshot, the DSI commands are labeled wronlgy as « Alarm bypassChX ». This will be changed to « Channel bypass ChX » in the next VS release 5.1.

New Features


VibroSmart® –new VSV30x firmwareNew feature Support for pre-logging / pre-triggerThe VSV30x module now supports pre-trigger data logging in the Alarm Event based data logging rule. The pre-trigger maximumsize is 50 seconds of trend data, waveforms, spectra and orbits with a resolution in time of every 100ms. The 50 seconds maximumbuffer size with a 100ms data resolution in time is fixed and not configurable.

1.5 Compatibility


VibroSmart® – VibroSight® compatibility

VSV30x monitoring module firmware version 18 (PNR642-001-000-018) is not compatible with earlier versions ofVibroSight:

VibroSight® software 5.0 fully support this firmware release

A VibroSight® software upgrade to version 5.0 is required in order to take advantage of the new features and

benefits in this latest VSV30x module firmware.

Configurations need to be updated and activated using VibroSight® software version 5.0.

Existing configurations are automatically converted by VibroSight, with no specific actions required from user.

Note: However, configurations cannot be converted back for compatibility with earlier versions of VSV30x

module firmware, so back up your configurations before updating.

Similarily, VibroSight® Vision corresponding to VibroSight® software version 5.0 or later is required to read

data/measurements from VSV30x modules running this latest version of firmware.

2.1 Narrow band vibration for

AC coupled input channels

Improvements and bug fixes


VibroSmart® –new VSV30x firmware Improvements and bug fixes NB vibration for AC coupled input channels

The AC+DC coupling restriction for the Narrow Band processing has been removed. This change now allow to usethe same input channel to perform either NB, AAB or BBP processing (everything can be set as AC coupling).

Before this change, the NB processing needed its input channel to be configured as AC+DC couling (all the signal without analog filtering). The reason was that the analog HP filter (configurable 0.1, 1 or 3 Hz) introduces a slight phase distortion for low frequencies. But for most applications, this is not important.


2.2 Direct waveform modification for

Hydro applications

Improvements and bug fixes


VibroSmart® –new VSV30x firmware Improvements and bug fixes Direct WF modification for Hydro applications

This improvement is preventing an intermittent mis-detection of poles when performing AirGapmeasurement. The issue was due to approximatedspeed information transmitted to the VibroSight serverand errors were accumulating. The fix is allowing all timestamps and indexes of the tacho to be transmitted toVibroSight.

The new FW 018 already contains the improvement butthe full integration with VibroSight will be effective withthe next 5.1 release. The tacho markers are alreadydisplayed but they are calculated from the waveformassociated speed value. The real tacho markers comingfrom the card will be available on the waveform plot.
