Version compatibility The following combinations must be fulfilled in order to guarantee an optimal working. Release date / MVX type CAST (firmware) Until September 2007 1.0xx 1.01.xx 1.00x 1.00x 3.05 From October 2007 2.0xx 2.xx 2.xx 2.xx 4.xx From October 2009 3.1.xx...
Hardware identification Year after year, MVX Hardware supported some changes. The hardware version of each MVX is available on the side label that is pasted on the left side, just near the fan entry. The following table gives the technical differences between the hardware versions:...
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.

(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.
Page 12
Real time indicators are achieved in the limit of the available MVX processing capability. An automatic control of the parameters embeds a checking of MVX processing load and cautions the operator when launching if overload is predictable. Brand of ACOEM...
2.3.2 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.
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.
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 Finder » indicator (SFI) This new indicator is able to detect abnormal shocks<;...
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.
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. 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.
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. 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.
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.
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.

Ethernet B port 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.
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...

Each PC must be setup with a fixed IP address: 192.168.103.100 & 192.168.103.101. Each MVX must be setup with a fixed IP address using CAST: 192.168.103.240 & 192.168.103.241. MVX Web interface The web interface allows to Look at MVX information, Modbus configuration, log files, date and time information, configuration files and also allows to update the firmware.
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.
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.
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.
7.3.5 Status of indicators The logical status of each indicator can take 4 different values: Value of logical status Description of indicator status Normal (OK) Alarm Danger Defect (transducer or other defect making measurement impossible) At address 2000, one can read hexadecimal 5555 value permanently, which allows checking the proper operating of the transfer connection.
7.3.6 Units of indicators Indicator units are coded as follows: Value Unit m / s² inch / s mm / s mils micrometer L / s kg / s °C °F At address 3000, one can read hexadecimal value AAAA permanently, which allows checking the proper operating of the transfer connection.
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.

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