1 Introduction

Thank you for purchasing the ONEPROD MVX monitoring and predictive maintenance system.

This performing system allows for the monitoring of industrial machines using 8, 16, 24 or 32 measurement channels, depending on the selected model.

ONEPROD MVX can also act as a synchronous multichannel acquisition system when connected to a predictive maintenance platform based on the ONEPROD NEST ANALYST (XPR) software package.

ONEPROD MVX can be connected to many transducers, even though its prime objective remains vibration measurement and analysis.

In case of a problem, please contact OneProd Hotline: [email protected]

2 Evolutions

2.1 Main evolutions of firmware version 5.4.0-7

WARNING : This firmware version is ONLY for MVX 1027000A, MVX1027000B, MVX1029000 and MVX1031000.

Firmware update through the MVX Web interface (not CAST anymore).

Operating conditions management: only 1 operating condition can be valid at a time. If more than 1 operating condition is valid, MVX takes the first valid condition of the list (list from XPR operating condition pannel)

Improved definition of operating condition limits :

o Low limit included(≥), high limit exclude (>)

Operating conditions can be available by OPC or by Modbus, not both at the same time.

Possibility to disable automatic reset in case of bad configuration in remote locations

2.2 Main evolutions of MVX version 5.1

Modbus Digital Inputs: Refer XPR software user manual to see the implementation of this feature. This mode cannot be used with CSM

The operating parameters are available through MVX Modbus output: cf. § 7.3.8

New management Ethernet ports: cf. § 6


2.3.1 Monitoring on 100% of the signal

This new functionality is available only on Premium MVX version

From V5.0.xx version MVX Premium is able to compute in real time a selection of indicators. The aim of such a function consists in ensuring that 100% of the signal is actually monitored.

11

Brand of ACOEM

Illustration:

“Standard” indicators are achieved at each cycle by MVX.

Thus, a very short phenomenon can be ignored if it happens during a processing phase.

RT indicators (Real Time) are achieved permanently during acquisition

Thus, 100% of the signal is actually monitored.

Thus the smallest transient phenomena can be detected (even if it happens only once and if it lasts some milliseconds), according adapted parameters (i.e. pick detection).

Besides it is obVIOusly possible to choose another set of parameters, which erases transient phenomena in order to avoid false alerts (i.e. RMS detection with several seconds time constant).

As a complement to such real time monitoring, MVX can record a new “Time waves on event” signal category (Please see next §).

The following processing parameters can be applied to define real time indicators which are monitored on 100% of the signals.

High pass filter : 2Hz or 10Hz

Signal integration : 0 or 1

Low pass filter : 1000Hz or no filter (i.e.20kHz)

Processing : RMS, pk or pk-pk

Averaging : continuous exponential with time constant between 1s and 25s

Averaged DC level (for process and GAP signals)

BGI indicator (Blade Guard Index)

GCI indicator (Gearbox Condition Index, see next §)

Broad band and narrow band extraction on real time FFT :

o FFT 400 pts, 800 pts, 1600 pts ou 3200 pts

o FFT 1kHz, 2kHz, 5kHz, 10kHz ou 20kHz,

o FFT with 50% fixed overlapping

2.3.2 “Time waves on event” signals recording

MVX Premium with DAT option is required

Besides real time monitoring MVX can record specific time waves that can be trigged at all time and that includes « pre-trigger » capability. I.e. possibility to include what happened BEFORE the trigger event.

Possible trigger events:

o Real time indicator alarm level VIOlation,

o Change in the operating condition,

o Manual measurement request (from XPR)

Time wave on event parameters:

o Fixed sampling rate: 51.2 kHz.

o Length: 1s to 30s on 32 channels

o Maximum length can be overstepped if less than 32 channels have to be recorded at the same time:

Number of channels concerned by time wave on event 32 24 16 8 4 3 2 1

Maximum duration (s) 30 40 60 120 240 320 480 480

Pre-trigger duration: 0 to total wave length (*).

(*) For first generation MVX which have been updated with V5.xx, the following limitations (due to internal RAM) are to be considered:

Note: Internal RAM cannot be upgraded.

2.3.3 DAT option performance optimisation

Firmware version 5.0.x.x improves substantially DAT performance in optimizing RAM management in two directions:

Limiting RAM consumption for a given configuration

Involving the additional RAM that is available on the last generation products (Please see §12)

2.3.4 BGI: for the monitoring of structures

BGI = Blade Guard Index.

BGI is a specific indicator, dedicated to monitor structural resonance phenomena. It can be particularly suitable for wind turbine blades when associated to specific sensors.

BGI requires DAT option in order to get time wave on alarm signal.

2.3.5 GCI: for particle counting

GCI (Gearbox Condition Index) is dedicated to particles counting.

GCI is available with MVX Easy or Premium.

Particle sensor (i.e. GASTOPS / MetalSCAN) are especially useful for degradations of the wind turbine gearboxes.

GCI is performed on 100% of time.

GCI is made with 3 sub-indicators:

GCI-h : number of particle detected in the last hour

GCI-d : number of particle detected in the last 24 hours (performed in a slipping mode)

GCI-t : Total number of detected particle

Each sub-indicator is monitored with its own set of thresholds.

2.4 Main evolutions of MVX version 4

In addition to the new functions described in the preVIOus chapter, Version #4.1 of the MVX firmware includes the following evolutions:

2.4.1 New « Shock FinderTM » indicator (SFI)

This new indicator is able to detect abnormal shocks<;

It is especially suitable for low speed machineries, where standard indicators (i.e. filtered RMS vlalues) are not always completely pertinent

Thus Shock FinderTM is suitable for windturbine rotor monitoring, steelmill or papermill monitoring, etc.

It can be used for rolling element bearings as well as gearbox monitoring.

Shock FinderTM also incorporates a smooth function dedicated for decreasing false alarm risk.

Please consult XPR300 V4.3 user manual (chapter 14.8) for more details about SFI set up.

Shock FinderTM can be setup with ONEPROD NEST ANALYST (XPR)

Shock FinderTM can’t be setup with OneProd CSM

2.4.2 Increase of the efficiency

MVX firmware V4.1 is based on a new operating system. Consequently MVX efficiency is increased.

The main observable improvement concerns the processing times that are lower vs preVIOus firmware versions.

Consequently a decrease of the cycle time is observed, allowing an improvement of the monitoring rate.


Version 3.1xxx of the MVX firmware includes mainly the following new functions:

2.5.1 Compatibility with the ESA analysis by ONEPROD-System

MVX is now compatible with the electric signal analysis (ESA) functions available in ONEPROD NEST ANALYST (XPR).

The analysis of electric signals consists in acquiring and analysing the power supply voltages and currents of a motor and detecting the distinctive characteristics thereof that indicate anomalies.

Electric or mechanical anomalies on the motor can thus be evidenced (unbalance, misalignment, broken bar, etc.).

2.5.2 Short-term memory

MVX stored in a FIFO buffer all or part of the indicators that were worked out during the monitoring measurements.

MVX can store up to 1000 values for each indicator, with a periodicity ranging from a few seconds (*) to 600 seconds.

This new function is available from ONEPROD NEST ANALYST (XPR) only.

17

Brand of ACOEM

(*): for a given application, the periodicity cannot be shorter than that for the calculation of the indicators by MVX.

Example:

When an indicator goes into alarm mode, one can know whether this indicator increased suddenly or progressively before reaching the alarm threshold.

2.5.3 OPC parameters via XCOM

When MVX is connected to XCOM (communication engine of ONEPROD NEST ANALYST (XPR)), it can now:

Monitor original OPC parameters (*)

Use original OPC parameters (*), such as condition parameters

(*): MVX does not have a local OPC connection. Parameters called “original OPC parameters” are retrieved by the OPC client of the XCOM component, which is physically located on the same PC as ONEPROD NEST ANALYST (XPR)

2.5.4 Priority management

MVX can now take into account three possible priority levels for each task.

This function allows for a better monitoring of machines with complex or random operating conditions.

2.5.5 Alarm triggering delay

The purpose of this function is to avoid untimely alarms due to interference or transient phenomena (e.g., related to the start of a neighbouring machine). It consists in, on request, acknowledging an alarm status ONLY if it is confirmed during a given period.

This function is accessible only from ONEPROD NEST ANALYST (XPR). A triggering delay is defined in seconds. If it is shorter than the cycling time, MVX performs at least one confirmation measurement.

18

Brand of ACOEM

MVX keeps it operating cycle and must confirm the presence of the alarm on all measurements collected over the defined time.

If the alarm level remains present during the defined time, MVX triggers the alarm status: relay, MODBUS status, acquisition on status change. If the level disappears, the alarm is no longer effective.

2.5.6 Vector tracking

MVX can now, and on request from ONEPROD NEST ANALYST (XPR), calculate phased spectra.

The phase reference that is taken into account is that of the trigger input corresponding to the machine under study.

19

Brand of ACOEM

3 MVX Operating

3.1 Principle

Unlike most predictive maintenance system on the market, ONEPROD MVX performs sequences of simultaneous acquisitions on all measurement channels.

These acquisitions are really synchronous and in phase.

3.2 Operating conditions

Signal acquisitions can be performed (depending on the configuration) under specific operating conditions for the machine(s) under monitoring.

These operating conditions can be:

A rotation speed, acquired by MVX through a “trigger input”-type frequency signal connected to one of the analogue inputs.

Values of one or two process parameters (power, temperature, etc.) acquired by MVX one of the analogue inputs through a continuous voltage or 4-20 mA current signal.

Up two 3 logical data (TTL signal) acquired by MVX on its logical inputs.

3.3 Operating in “Monitoring” mode

When MVX is set up to perform monitoring operations, the processing of data acquired simultaneously aims at calculating indicators and comparing them to alarm thresholds.

This calculation is performed:

During acquisition for the real time indicators (MVX Premium only)

After each acquisition phase for the standard indicators.

Thus, MVX alternates acquisition and processing phases and a set of updated “results” indicators is available after each processing phase.

20

Brand of ACOEM

Spectra calculated for the extraction of indicators can neither be viewed nor stored by MVX.

3.4 Operating in “Predictive Maintenance” mode

When MVX is set up to perform predictive maintenance tasks, it performs the required acquisition(s) as soon as the fixed period or date has expired.

In this case, all signals (spectra and/or time signals) and indicators described in the configuration are stored by MVX in order to be integrated into the predictive maintenance database, either at once, or later on.

Between two scheduled operations, MVX can permanently calculate scalar indicators described in the settings and compare them to alarm thresholds, like in the monitoring mode.

In case of status change (threshold VIOlation), all measurements (spectra and/or time signals) and indicators described in the parameter settings are stored by MVX to be later integrated to the predictive maintenance database.

Short-term memory:

Furthermore, and for each calculated parameter, MVX will store in a FIFO buffer the short-term history of scalar values.

The size of this FIFO buffer can be set up to 1000 values per indicators.

The periodicity for storage in the short term memory can also be programmed and can range from a few seconds (i.e., MVX stores all calculated values) to 600 s.

By storing 1000 values with a periodicity of 600s, the capacity of this short-term memory can thus reach 600 000s, i.e., about 1 week.

21

Brand of ACOEM

4 Set-up

When only monitoring tasks (to the exclusion of any predictive maintenance tasks) are to be assigned to MVX, the OneProd CSM set-up interface should be used.

This interface is used to set up MVX; it does not allow for visual display or processing of measurement results.

To assign predictive maintenance tasks to MVX, one should use MVX jointly with the ONEPROD NEST ANALYST (XPR) predictive maintenance software program.

This platform will perform the set up of MVX, as well as the processing of measurement results.

In both cases, the communication between MVX and the computer hosting OneProd CSM or ONEPROD NEST ANALYST (XPR) used an Ethernet connection: existing network or point-to-point connection.

4.1 Setup with OneProd CSM

While remaining a user-friendly interface, CSM can be used to set up simple, as well as more specific, monitoring tasks.

The use of ONEPROD CSM is described in detail in a dedicated user manual.

Note:

CSM isn’t suitable to setup real time indicators

CSM isn’t suitable to setup SFI indicator (Shock FinderTM).

CSM isn’t suitable to setup GCI indicator (Gearbox Condition IndexTM)

CSM isn’t suitable to setup time wave signals

4.2 Set-up with ONEPROD XPR

XPR is a global, multi-technique, performing predictive maintenance software package.

In particular, it allows for the management of production assets under both “off-line” and “on-line” monitoring.

There is a separate user manual devoted to ONEPROD NEST ANALYST (XPR).

CAUTION

Although set-up structures are compatible, we strongly recommend that the use of XPR and CSM never be combined to set up a MVX module.

6 Connecting MVX on an Ethernet network

6.1 Ethernet port selection

There are two RJ45 type Ethernet sockets on MVX: A & B.

They are located on the bottom of the MVX case.

Connecting MVX to an Ethernet network is possible using A or B socket.

Only one socket can be used at a time.

These two connectors may be used but their pin assignment are not identical:

2 USB ports (not used)Ethernet A port Ethernet B port

netwok led indicators

Port A (or « left »port): standard (non crossed, same as a PC):

In order to connect MVX to a factory network through A port, you have to use a standard (uncrossed) cable.

In order to connect MVX to a PC through A port, you have to use a crossed cable and to setup beforehand MVX in Fixed IP address mode.

Port B (or "right" port): crossed.

In order to connect MVX to a factory network through B port, you have to use a crossed cable.

In order to connect MVX to a PC through B port, you have to use a standard cable.

Addressing mode led: fixed or dynamic addressing mode

24

Brand of ACOEM

Please note that some recent Ethernet switch and portable PC automatically cross or uncross their port.

IMPORTANT - Rules for the use of Ethernet ports:

It is recommended to use preferably the port B. This port can handle the communication with the software OneProd (XPR, CAST, MSC, VIO) and PLC via Modbus TCP.

If the Modbus devices are on a different network then connect them on port A

When the connection is OK, a green indicator lights on the RJ45 socket (high & right corner, see on the upper scheme)

You have to reboot the MVX after any change on the network connection

After connecting MVX to an Ethernet network:

- Startup MVX

- Please verify that the light is green on the RJ45 socket. If this indicator remains off, the network is off or the cable isn’t appropriate.

6.2 IP addressing mode

6.2.1 Default address mode

As default, the two MVX Ethernet ports are « Dynamic IP » configured:

When starting, MVX looks for a DHCP server on the network in order to get an IP address.

If a DHCP server is present on the network (dynamic IP addresses network), MVX IP address isn’t known, and the serial number of the MVX is used as the « hostname ».

If no DHCP server is present on the network, then MVX chooses an IP free address in the range 169.254.x.y on its B port, right side. In this case use also MVX serial number as « hostname » to address it.

This addressing mode can be restored using the Reset button: cf. § 8.4

Warning : from V4.1.x .x MVX firmware, A port doesn’t focus automatically to a default fixed IP address. You shall use B port or you shall setup A port in fied IP address mode with CAST

25

Brand of ACOEM

6.2.2 MVX dynamic address mode

This is the simplest case: MVX IP address is arbitrary because chosen by the DHCP server.

MVX user does not use this IP address.

He names each MVX with its “Hostname”, which is in fact its serial number.

When MVX is running with an Ethernet port programmed in dynamic address mode, the led in the high & left corner of the RJ45 socket is light on in GREEN.

6.2.3 MVX fixed address mode

Reminder: When MVX is set up in dynamic addressing mode and when no DHCP server exists at the same time on the network, then MVX chooses an IP free address in the range 169.254.x.y on its B port, right side. In this case use also MVX serial number as « hostname » to address it.

In order to connect several MVX on a fixed IP addresses network, you have beforehand:

To define the MVX list with the serial number and the IP address of each.

To connect each MVX with a PC in a « point to point » network, in order to assign its fix address.

This operation may be achieved with CAST toolbox which is delivered together with MVX.

Start CAST toolbox in the “expert” mode (password needed)

Enter the MVX serial number or its “old” IP address

Click on the “connect to MVX” button

Choose the “configuration” page

In the “Set fixed IP address” area:

o choose the MVX port that you want to use: A port (left), or B port (right)

o Enter the new IP address

o Enter the subnet mask

o Enter the default gateway

o Click on "configure"

This may cause MVX re-boot.

When MVX is running with an Ethernet port programmed in fixed address mode, the led in the high & left corner of the RJ45 socket is light on in RED.

6.3 How to check the Ethernet connection

The network “connection status” should indicate “connected”.

With Windows XP, the connection status is available through:

A double-click on the icon into the “task bar”

Or in the “network connections” item of the “control panel”.

The “ping” command may be used in order to check the MVX response time.

Click on Start - Run

Type cmd and click on OK : A DOS window is open

Type ping [MVX IP address] or ping [MVX serial number]

Example:

C:\>ping 192.168.103.240

Pinging 192.168.103.240 with 32 bytes of data:

Reply from 192.168.103.240 : bytes=32 time<1ms TTL=128

7 Using the MODBUS output interface

7.1 General points

Whether it runs with XPR, with VIO or in stand-alone mode, MVX computes and updates as often as possible a number of scalar levels (called “overall levels” or “indicators”).

All these levels can be consulted using the dialogue function in MODBUS format.

The status of these indicators (OK, Alarm, etc.) is also available, along with their unit.

In any event, MVX is a MODBUS slave that answers requests issued by a Master. This Master is usually a programmable automaton, a centralized management system or a monitoring system.

7.2 Communication principles

Data in MODBUS format can be accessed:

Either using the RS485 connection on MVX: “Serial MODBUS”

Or using the Ethernet connection of MVX: “MODBUS-TCP”

7.2.1 Serial MODBUS with RS485 connection

The RS485 standard allows for the creation of a local network made up of a twisted and shielded pair onto which up to 32 instruments can be connected.

In practice, one needs to connect one or several MVX instruments to a single “master” instrument.

We recommend reading Chapter 3.9 of MVX installation manual P153.NUT.576 before achieving the physical connection of instruments.

It is possible to adjust RS485 configuration (baud rate, parity …) with CAST software.

Each MVX is assigned a MODBUS slave number ranging from 1 to 32. The MODBUS slave address of each MVX is set from the ONEPROD NEST ANALYST (XPR) software or from the OneProd CSM software.

31

Brand of ACOEM

7.2.2 MODBUS-TCP with Ethernet connection

MODBUS data are available through a MODBUS TCP protocol, which is constantly active over the network.

IMPORTANT - Rules for the use of Ethernet ports:

It is recommended to use preferably the port B. This port can handle the communication with the software OneProd (XPR, CAST, MSC, VIO) and PLC via Modbus TCP.

If the Modbus devices are on a different network then connect them on port A

Conventions:

Data in MODBUS-TCP format are available through the standard 502 port.

The MODBUS slave address must be set to 255 in requests (in this case, the IP address is used to select each MVX).

CAUTION

The slave address had to be fixed at 1 (instead of 255) in the previous versions of MVX.

This change can result in malfunction after upgrading MVX firmware to V5.0

Adress #255 allows for a better compatibility vs MODBUS-TCP standard..

7.3 Data format

The MODBUS interface is used to read values, statuses, units and thresholds of indicators computed by MVX.

7.3.1 Available indicators

Using software programs XPR or CSM, one can program up to 255 different indicators in MVX.

Each indicator is assigned a number (ranging from 1 to 255), which is part of the indicator’s parameters and is entered upon programming.

For more details, refer to the user manuals of XPR or CSM.

It is to be noted that MVX channels do not correspond to the indicator numbers. As an example, a single channel can result in the computation of about 10 different indicators, whereas another channel, which remains unused, will not issue any indicator and will therefore no longer exist in the MODBUS dialogue.

7.3.2 Modbus requests

The MVX answers the function with code 03: Read Holding Registers.

Available data are described in the paragraphs below.

7.3.3 Number of indicators

The number of indicators programmed in MVX is available at address “zero”.

7.3.4 Values of indicators

Data are in IEEE floating format over 32 bits.

Two consecutive addresses are then required for each indicator value.

At address 1000 (& 1001), π (PI) value “3.1416” is displayed permanently, which allows to check the proper operating of the connection.

Indicator values are available in an address range from 1002 to 1513 and sorted according to the table below:

7.3.7 Threshold values

Alarm and Danger threshold values are available provided that the corresponding indicators are achieved in one operating condition only.

In other words, this function is not suitable when indicators are calculated in several operating conditions and monitored with different sets of thresholds,.

As well as indicators, data are stored in IEEE floating format over 32 bits.


There are 4 thresholds for each indicator, even if all of them are not used in all cases.

At address 4000 (& 4001), π (PI) value “3.1416” is displayed permanently, which allows to check the proper operating of the connection.

Indicator threshold values are available in an address range from 4008 to 6055 and sorted according to the table below:

8 Maintenance

8.1 Preventive maintenance operations

The MVX system does not require any specific operation for its maintenance, except for dust cleaning on the ventilation inlets.

To do so, disconnect MVX from the power supply.

In case of a particularly dusty atmosphere, it can be useful to get rid of the dust accumulated inside MVX.

To do so, please contact 01dB-Metravib’s after-sales department.

8.2 Replacement of the battery

The theoretical lifetime of the data back-up battery is several dozen years for a MVX module under constant voltage.

Replacing this battery may however be necessary every 10 years.

Also, we recommend that the battery be replaced as soon as the MVX module has remained totally unused for more than a year.

To replace the back-up battery, please contact the 01dB-Metravib’s support.

(see page 2).

8.3 1st level diagnosis

8.3.1 Normal boot sequence

If To is the Power-on instant, the normal boot sequence is:

To: The “power” green led lights. All the other leds are “ON” too.

39

Brand of ACOEM

~To + 60 seconds: Red leds are flashing on the two RJ45 Ethernet connectors.

~To +70 seconds: All the leds are flashing. Then A & B leds are staying lighted for a moment.

~To + 100 seconds: Integrity relay becomes energised; A & B leds become OFF: the MVX is ready to work.

8.3.2 Regular working operations

When MVX is normally working, A, B and C leds are flashing:

A Led: lights during signal acquisition

B Led: lights during post-processing operations

C Led: fleetingly lights during each network access

8.3.3 Bias voltage monitoring

When bias voltage monitoring is activated, MVX inserts periodically a specific sequence for that goal.

During this sequence, A Led flashes quickly 6 times.

8.3.4 Offset compensation

When a new configuration is transferred to MVX, it does not start immediately with its nominal operating mode, as described in the previous two paragraphs.

MVX goes into an initialisation phase, during which the two LEDs A and B blink quickly and simultaneously.

This phase usually lasts about 15 seconds.

However, if instrument property “Offset adjustment” is activated in XPR, this initialisation phase may last several minutes.

8.3.5 Defects indicated by the MVX leds

8.3.5.1 All the leds are ON

If all the MVX leds are staying ON during more than 2 minutes after powering, it means that an internal electronic failure exists.

In this case please contact the 01dB-Metravib’s Hot-line (see page 2).

40

Brand of ACOEM

8.3.5.2 The “SYSTEM” led flashes quickly (3 times per second)

MVX could not start because of a general acquisition defect.

MVX is not able to work. Its integrity relay is not activated.

In this case please contact the 01dB-Metravib’s Hot-line (see page 2).

8.3.5.3 The “SYSTEM” led flashes slowly (once each 3 seconds)

A partial defect has been detected. Examples:

One acquisition channel is defective.

Acquisition memory is full because MVX work exceeds its possibilities.

An acquisition operation has been delayed because more than 32 channels were to be acquired simultaneously.

The Compact-Flash memory is full because communication with XPR is defective.

In each case it is possible to know the defect details using the “Read MVX states” button of the CAST Toolbox.

8.3.5.4 The SENSOR led flashes slowly (Once each 3 seconds)

There are 3 possibilities:

One IEPE sensor (or more) has been detected defective,

One channel (or more) has been detected as overloaded,

The current in one of the “4-to-20mA” input is less than 3.5 mA, or more than 20.5 mA.

In all these cases the integrity relay is not energised

As well as before it’s possible to know the defect details using the “Read MVX status” button of the CAST Toolbox.
