2 Foreword
M-Log datalogger has been designed for environmental applications; it comes from E-Log
primarily and utilizes the same use modes and management programs (3DOM, Gidas …)
Thanks to its low power consumption, its sizes, the range of signals that it can receive, the
protection as regards heavy environmental conditions and possible overvoltages, M-Log datalogger
is particularly suitable for measurements of weather, water, air quality, indoor and outdoor
environmental monitoring applications.
M-Log line is divided in two big typologies (you can find the detailed list of models in §3.2):
M-Log with inputs suitable to receive sensors with connectors for automatic configuration
by means of recognition resistance; it’s suitable for indoor applications (microclimate).
M-Log with terminal board inputs; it’s suitable for outdoor applications (meteorology).
M-Log can be fitted with a wide range of accessories to enhance its power autonomy, to protect it
against extreme weather conditions and for data transmission via RS232/485, USB, Ethernet,
modem PSTN/GSM/GPRS.
2.1 Disposal
M-Log is a highly electronic scientific device. In accordance with the standards of environmental
protection and collection, LSI LASTEM advises to handle M-Log as waste of electrical and
electronic equipment (WEEE). It is therefore not to be collected with any other kind of waste.
LSI LASTEM is liable for the compliance of the production, sales and disposal lines of M-Log,
safeguarding the rights of the consumer. Unauthorized disposal will be punished by the law.
Dispose of the dead batteries according to the regulations in force

3 Guide to the start
3.1 Description
M-Log is leading-edge datalogger worked out by LSI LASTEM, and thanks to its multimeasurement system it’s suitable for all environmental applications.
The front panel of instrument is equipped with illuminated display (4x20 characters), signalling
bright leds, function and arrow keys.
On top side of instrument there are the communication devices (according to the model: serial port
or Ethernet output), the Reset key, the socket for connection of external power supply system.
On bottom side we can find the inputs for connection of sensors; according to M-Log model, for
connection of sensors, it’s possible to find fix mini-din connectors (models series ELO009), or
usual terminal board with pluggable terminals; in last case extract the terminals from their housing
using a suitable tool.

3.3 Mechanical and electrical installation
M-Log is able to be used for both internal use (placed on a flat surface of fixed onto a wall) and
external use (inside suitable protection boxes).
The use of supports furnished by LSI LASTEM is advisable for indoor applications:
BVA304
Universal tripod to support BVA311 stand
BVA311
Stand for support of n.5 probes and M-Log on tripod or on wall
BVA312
Stand for support of further n.5 probes and M-Log on BVA311 or on wall
BVA314
Sidebar for support of stand on the wall
3.3.1 Instrument power supply
M-Log is equipped with 1,95 A, lithium ion, internal rechargeable battery.
All models can be powered by an external power supply pack (8 ÷ 14 Vdc), by means of connector
placed on top panel of instrument; in this case the positive pole is pole inside the connector. In any
case pay attention not to invert the power supply polarity (although the instrument is protected from
wrong procedure).
For ELO007 and ELO008 models is also possible to power by means of terminal board.
Make reference to table below for connection with instrument-input and sensors-output powersupply terminals or other devices that need power supply.
Connection

0 Vdc battery
28 or 29
+ Vdc battery / + Vdc fixed to power sensors
and external devices
30 or 31
GND
32
When there’s GND wire (grounding), it’s recommended to connect it with 32 terminal.
In case of no switch on of the device, push the RESET button (located on the higher panel of the
instrument) and then try to push the keys combination for switch on; if the sensor is still off, send it
for repair at LSI LASTEM.
WARNING: in case terminals 5-6 and 16-17 feed outside equipments, they must be equipped with
power fail circuit against short circuits or absorbed currents above 1 A.
WARNING: in applications where there is LSI LASTEM BSO103.1 sensor (CO2 probe), M-Log
datalogger must be powered by means of external power supply pack; the only M-Log internal
battery isn’t able to supply enough power for right operation of connected sensor.
3.3.2 Internal rechargeable battery
The internal rechargeable battery ensures to the instrument the autonomy, the independence and the
handiness during different applications that involve it; it is normally subject to unload. The low
battery signalization occurs on datalogger through three times blinking of LED ▄-Err (see §Errore.
L'origine riferimento non è stata trovata.).
Page 10
LSI LASTEM M-Log – User’s manual
10
The total discharge of the battery will lose the date/time of the datalogger; this condition is very
dangerous because it makes the stored data unreadable so also compromising the operation of data
unloading and data storing on the acquisition system.
Note: It’s advisable to check the date/time displayed by the datalogger and eventually update to the
current date/time through 3DOM software (see §4.5.2 of SWUM_00339 manual reported on LSI
LASTEM products DVD MW6501):
- before starting the survey;
- before and after operations of battery recharge;
- after a long period of inactivity;
- when the message of low battery is displayed (see §Errore. L'origine riferimento non è stata
trovata.).
3.3.3 Inputs and actuators
3.3.3.1 ELO007-ELO008-ELO009 models
The instrument is fitted with 4 analogue inputs in differential mode and 8 in single-ended mode
(§3.3.4Errore. L'origine riferimento non è stata trovata.) (independent, for sampling of voltage
signals, current, resistance, Pt100 with three or four wires, thermocouples), a digital input (for
sampling of pulse inputs, frequency or digital state) and 2 actuators used to power the sensors
connected to the terminal board; the actuators can also be used by the actuation programmable
logics, than can produce alarms according to the values acquired by the sensors . The voltage
available on these terminals depends on the kind of power supply received by the instrument.
Use the program 3DOM (see SWUM_00339 available on LSI LASTEM product DVD – MW6501)
to configure the operation to switch on the sensors by means of the switching powers. In order to
choose the actuation time is advisable to consider both the energetic saving and the time the sensor
needs to initialize.
The association between input and switching power is fixed, as shown in the table below. The
number of the terminal is indicated in italics; we understand, for example, that inputs 1 and 2 both
make use of the first actuator; therefore it cannot be used for the other inputs. In case of sensors that
generate two signals (like the thermo-hygrometric sensor), it’s suitable to select both inputs that use
the same actuator.
A third actuator is on the pin9 of the serial port connector 1 and it can be used for sensors that
interface to M-Log with serial connection; if configured appropriately with a logic based on the
power level or battery power level, it can be used as fixed power supply.
All the actuators can be activated manually by the diagnostic window type 4 (see §4.3.4).
The following tables show the terminals used to connect sensors and power supply for ELO007 and
ELO008 models.

The drop resistance, indicated by Rx, is used to return a voltage signal from the current generated
by the sensor. Program 3DOM supplies a library for the setting of the LSI LASTEM sensors,
including some powered outputs; for such models the settings have been arranged to use the
energized scale -300÷1200 mV, thus being able to use 50 Ω drop resistances.
Sensors with digital signal:

3.3.3.2 ELO011 model
The instrument is fitted with a digital input (for sampling of pulse inputs, frequency or digital state)
and an actuator that switches the power supply on pin 9 of the serial port connector 1. The actuator
can be used for sensors that interface to M-Log with serial connection; if configured appropriately
with a logic based on the power level or battery power level, it can be used as fixed power supply
by the connected device.

3.3.4 Single-ended inputs
Starting from datalogger firmware version 2.10.00 (model ELO011 excluded) it is possible to
double the number of analogue inputs, passing from 4 to 8. This function is available only for
sensors with current signals (this function is called single-ended). Resistive signals, instead, go on
occupying a full single physical input (this function is called differential).
Differential inputs are more immune from electromagnetic disturbances than single-ended ones and,
when possible, they have to be preferred.
Page 13
LSI LASTEM M-Log – User’s manual
13
All sensors generating current signals and all powered sensors can be connected to single-ended
inputs (see connection scheme).
WARNING:
To R/M Log instruments it is possible to connect only: radiometers, thermo-couples, fluxmeters or
signals externally powered (see connection scheme)

The drop resistance, indicated by Rx, is used to return a voltage signal from the current generated
by the sensor. Program 3DOM supplies a library for the setting of the LSI LASTEM sensors,
including some powered outputs; for such models the settings have been arranged to use the
energized scale -300÷1200 mV, thus being able to use 50 Ω drop resistances.
When a probe is added using the 3DOM probes library, those sensors are always added in
differential mode; for this reason is not possible add a single-ended probe to a configuration where
there is only one single-ended sensor free; when this situation occurs set the measure parameters
manually matching the single-ended probe needs; otherwise change, if possible, different measures
from differential to single-ended mode until obtaining a complete differential input free (two singleended sequential inputs).
3.3.5 Serial communication lines
All the M-Log dataloggers are equipped, on the upper panel, at least with one communication serial
port (furnished with douple connector, DTE and DCE; female if the datalogger is used as a DCE
device, male if it is used as a DTE device); ELO008 and ELO009 have another communication
serial port (only in DTE mode). Serial port are used to program the instrument's operative modes
and data download, by means of the LSI CISS communication protocol.
The serial port leaves our factory with the following default configuration:
Baud rate: 57600 bps;
Data bit: 8;
Stop bit: 1;
Parity: none;
Network address: 1.
Page 14
LSI LASTEM M-Log – User’s manual
14
The instrument can be programmed; however only the baud rate and network address can be
changed; all other parameters cannot. The rate can be programmed from 1200 to 115200 bps; in
case of use of phone modem GSM/GPRS it is suitable program 9600 bps on bound rate.
Electrically speaking, both ports are configured as a DCE device. The following table shows the
meaning of each serial connectors' pin:

3.3.6 Modem power supply
M-Log can power the modem continuatively (through 12 Vdc powering from the terminals, like
shown at §3.3.1), or through timed actuator, in order to reduce the electric energy consumption of
the system.
You must use actuator n.3 to power the modem through actuator. Activate it according to the
different connected modem:
GSM Modem: the actuator is started at time of instrument starting; in this case the telephone
connection holds on also during the remote re-configuration of the instrument through
3DOM program; the next shutdown happens by means of the timed actuation logic,
according to the programmed shutdown time; i.e. in case of following programmed timed
logic, starting at 15:00 o’clock and shutdown at 16:00 o’clock, if the instrument is started at
14:30, the effector will operate one hour and half;
GPRS Modem: the actuator is started at time of instrument starting and the shutdown
happens about one minute later; next modem activation will happens according to the GPRS
data transmission timing, as programmed with 3DOM.
3.4 Configuring the operative mode
The instrument supplied by LSI LASTEM is equipped with standard configuration that includes
only the battery tension and the internal temperature; for models series ELO009 it’s possible to setup the configuration automatically, as they are equipped with function for sensors auto-recognition;
but configuration of models ELO007, ELO008 and ELO011 must be set-up by means of 3DOM
software, through the direct input from software library or through support of suitable models
designed for different user applications (microclimate, walls transmittance …)
Both the measurements autogeneration and the applicative models produce the generation of only
type “Ave” elaborations (mean value). When configuration is set-up starting from sensors in 3DOM
library, it’s possible to obtain the generation of more complete processings (“Min/Ave/Max”, “Tot”,
“Stdev”, “%valid data” …); so in this case it’ll be possible to delete, manually, the elaboration you
aren’t interested in.
Page 15
LSI LASTEM M-Log – User’s manual
15
For all M-Log releases the modification of configuration, in order to obtain new setup satisfying
with one’s own needs, is made through PC connected to serial communication port 1 with 3DOM
program; the serial port 2 (model ELO007 excluded) can be used for configuration upload only
when it is configured to use CISS protocol.. For details about all settable parameters, make
reference to online help of this program or user manual DVDs made by LSI LASTEM. For
connection of serial line and its programming, see §Errore. L'origine riferimento non è stata
trovata..
During the configuration data upload (by means of the 3DOM program) the survey (in progress in
the instrument) is closed, in order to allow to the instrument the right reconfiguration condition. At
this point the measures list on the display (see §Errore. L'origine riferimento non è stata
trovata.) is replaced with the notice “Survey halted”; it means that the survey has been halted.
Note: when programming a new configuration, all data stored in the instrument's memory will be
deleted. For this reason we advise to receive on PC all data from the instrument before uploading
the new configuration.
3.4.1 Language configuration
The instrument always uses English language for display messaging; for measurement texts it is
factory programmed to use Italian names but this can be changed by 3DOM configuration program.

and stay awaiting for confirmation through key before you start the operations for autorecognition of probes.
At the end of auto-configuration function, if the instrument hasn’t found any errors, a new survey
will be started and new mask of instantaneous values will be displayed.
Warning: this operation will delete all stored data; before you confirm the auto-recognition,
download the stored data on PC.
4.3.1.4 Record the starting and ending time of data acquisition (Survey n)
M-Log is a mono-survey instrument, but offers to the user the possibility to mark the time of
surveys; in other words it allows to fix manually, for one survey, the starting and ending time of
data acquisition. These information are shown by LSI LASTEM application programs (such as
Microclima) in order to make easy the selection of data included into given period of sampling.
The starting time, to consider data, is fixed pressing and keys at the same time; display
will show following mask:

But pressing again and keys at the same time it’ll be fixed the ending time; the
instrument will continue to save the data, but not inside survey closed before. An univocal numeric
value n will identify the selected slot; n will be increased every time a new slot for acquired data
consideration is fixed. The reset of survey number is made only modifying configuration from PC
or starting new auto-recognition procedure.
4.3.1.5 Reset statistics
Pressing and keys at the same time, it’s possible to reset values of diagnostic mask
statistics number 2 (see §4.3.4), in other words the values referred to communication (bytes and
transferred and received messages).

4.3.1.6 Fast transmission mode
Pressing and keys at the same time from diagnostic window type 2, it’s possible select
the sensor fast transmission mode (transmission every second). This function will be active only if a
value different from 0 is set in the Serial communication port x Instantaneous values automatic
transmission rate option (x takes values 1 or 2 according to the relative serial port) in the
configuration send to the instrument. The fast transmission mode will be activate only on the serial
port that is interrogated during the display of diagnostic window: when you display the diagnostic
window type 2 relative to the serial port 1 (C1), the keys combination and will activate
the fast transmission mode only for coomunication serial port 1.
Pressing again the same keys combination, the transmission mode will return to work according the
configuration’s parameters.
4.3.1.7 System clock setting
A few seconds after being switched on, the instrument can require to re-set the clock (date and
time). This can happen only in particular situations as, for example, the complete discharge of the
battery: in this case the date/time setting is compulsory and cannot be cancelled.
The date/time changing can anyway be performed whenever desired from the Diagnostic window
type 1. Use the following keys:
: enter change mode; exit from change mode confirming and storing the new date/time;
: exit from change mode discharging possible modified values;
: move the cursor over the field to modify;
: it augments the value selected by the cursor; other elements of date/time can change
contemporarily;
: it reduces the value selected by the cursor; other elements of date/time can change
contemporarily.

this reason the memory is virtually end-less. The calculation of
availability is made according to total memory space dedicated to
elaborated data in comparison with data already transferred to PC
from serial line; during the reading of elaborated data this value is
updated continuously in order to specify the percentage of available
memory in relation to datum is being read from one instant to the
next; if the instrument shows that percentage value is zero, it means
that circular storage algorithm has stored new data and deleted the
older ones.

This mask is very important for diagnostic reasons, in order to value the quality of communication
among M-Log datalogger (configured in master-slave mode) and between M-Log and PC.
Communication between PC and M-Log
Every standard message consists of about 13 characters; so:
In case of reception of more than 13 Rx
characters and no increase of Rx of Msg value
M-Log bit rate could be higher than rate set on PC
In case of reception of less than 13 Rx characters
and no increase of Rx of Msg value
M-Log bit rate could be lower than rate set on PC
In case of rates set correctly, right reception of
characters but not decoded message (Msg value
doesn’t increase)
Could have been used different protocols or could be
communication electric problems (i.e. on 485 line, + and could have been inverted) or communication line is too
jammed.
In case of: rates set correctly, right reception of
characters, encoded message but no answer (Tx
of Msg value doesn’t increase)
The addressee of message isn’t stated M-Log but an other
datalogger: check network address (Protocol ID)
Communication among M-Log datalogger
The correct datalogger communication can be checked displaying that the following fields are
increased the same value with similar timing:
- Byte and Msg fields of Tx for communication serial port of slave datalogger;
- Byte and Msg fields of Rx for communication serial port of master datalogger.

can be checked by means of any program for terminal emulation for diagnostic purposes.
Note: the communication values can be changed by means of keyboard but this is a transitory
modify, because it’s arranged to solve quickly possible communication problems with the outside
equipments; in fact every time the instrument is switched on again it uses the PC’s programmed
configurations. Use 3DOM program to program these setups definitively.

^ indicates the selected actuator;
zzz: percentage value of power battery of the instrument. When the datalogger is
externally powered displays a value below 100% (60% typically) even when the
battery is fully charged (can be determined by switching off the charging LED on the
frontal panel); removing the external power supply the value of battery is shown
correctly. This feature is similar when “battery voltage” is a sampling measure.
For diagnostic uses, use the keys to shift on the selected actuator (indicated by ^ symbol)
and key to shift from switched on to switched off modes and viceversa .

From 2.3 firmware version it is possible to force the actuator state among to the internal logics that
could change (actuators logics or sensor power supply logics); in addition to the 0 value (actuator
off) and 1 value (actuator on) is shown the F letter, one for each actuator, if the forcing is active.
In practice, if the forcing is also imposed to an actuator state (that can assume 0 or 1 value) means
that actuator will never be change by any internal logic (except the commands received from remote
through CISS communication protocol or Modbus that have priority on F status); if the F forcing is
off, the internal logic can normally change the actuator status.

4.3.5 Shutting off the display
Shut off the display allows to save about 25 mW. It is therefore important to keep the display shut
off whenever possible when the instrument is running on batteries with or without sun panels.
To shut off the display you can use the keyboard (see §4.2) or use program 3DOM to have it shut
off; to do so, modify parameter "Characteristics – auto display shut off". By setting this parameter
to Yes, M-Log will shut off the display after the keyboard remains inactive for three minutes.
4.4 Reset button
On the bottom panel, together with inputs for sensors (with terminal board or mini-din connectors),
there’s an hole for access to Reset key; the latter is only accessible through a pointed object (such as
a straightened paper clip) and allows to instrument the reset of its possible block condition. Inside
memory will remain the instrument configuration, processed data and date and hour of system; on
the contrary all statistics will be reset.
4.5 LED’s
On frontal panel of M-Log there are four bright indicators (LED) that display the operation state of
instrument (OK/ERR), the communication from and to external devices (Rx/Tx) and the chargecondition of inner battery.
See below a detailed description of each state.

5 M-Log additional features
M-Log is an instrument designed to acquire, elaborate and store measures from sensors connected
to its analogue, digital and serial inputs. On the base of the acquired data it can operate field
actuations according to the programmable algorithms.
5.1 Starting and running the survey
Note: The first operation to do after turning on the instrument is to check the date and time
displayed by the datalogger; in case of disagreement with the current date and time, update them
(see §Errore. L'origine riferimento non è stata trovata.).
M-Log performs the measurements and processings as they always belong to only one survey. The
execution of survey is made in automatic way, few seconds after the starting of instrument.
The features of datalogger configuration can be changed through software 3DOM; after a
configuration change and its transmission to the instrument, all data in the memory will be
automatically deleted and a new survey will start. The data management is allowed by application
software on the PC.
5.1.1 Automatic recognition of probes
M-Log dataloggers complete with inputs with mini-din connectors (series ELO009) are equipped
with function for auto-recognition of probes made by LSI LASTEM.
The inner library of M-Log allows the instrument its auto-configuration according to LSI LASTEM
sensors physically connected to datalogger (for its operation see §4.3.1.3); the library assigns the
respective measurements (acquired and calculated) to each specific recognized sensor and in this
way it automatically setup the configuration with more suitable parameters.
The measurements configured in this library (programmed thanks to experience of LSI LASTEM
engineers) have acquisition times and other management modes in accordance with type of
measured quantity. It’s however possible to modify the configuration parameters (processing time,
acquisition rate, name of the measurement …); in order to carry-out this modification, follow the
instruction below:
1- open 3DOM software;
2- download configuration from instrument (see §4.4.8 of SWUM_00339 manual);
3- modify the interesting parameters (see §4.4 of SWUM_00339 manual);
4- save the configuration and re-send it to instrument (see §4.4.7 of SWUM_00339 manual).
The programming of new configuration produces the erasing of all data in the instrument
memory; for this reason it’s recommended to transfer data on PC, through same program,
before you setup new configuration.
In order to allow the instrument the right acquisition, the acquisition rates of measurements must be
lower or equal to elaborated rate. During auto-configuration function, one or more measurements,
having acquisition rate higher than rate setup for processing, can be generated in M-Log; to avoid
this possible error, M-Log has been equipped with function of automatic correction that restores the
acquisition rates (if they are higher) equal to elaborated rates automatically.

During auto-recognition function could be pointed out some errors; here below the codes and their
relevant meanings:
1
GR_CISS_Error
In the instrument the library of sensors includes the
description of sensor or non-valid measurement
2
GR_EmptyLibrary
The instrument doesn’t include a valid library of
sensors
3
GR_ParamNotFound
The measurement doesn’t include the placeholder
for demanded parameter
4
GR_UndefinedProbe
The connected sensor hasn’t been defined in library
of instrument
5
GR_UndefinedMeasure
The connected sensor generates a measurement that
hasn’t been defined in library of instrument
6
GR_DepMeasureNotFound
One calculated measurement requires one
dependent measurement (acquired or calculated by
same or other sensors) that hasn’t been generated
7
GR_DepMeasureMarkerNotFound
The tag for dependent measurements, included into
measurement definition, hasn’t been found
8
GR_MeasureUpdateRateNotFound
The tag for the update rate, included into
measurement definition, hasn’t been found
9
GR_SensorCalibrMarkerNotFound
The tag for calibration value, included into
measurement definition, hasn’t been found
10
GR_UndefinedProbeCalibrParam
One connected sensor requires the definition of
calibration value that hasn’t been defined in
standard quantities (*)
11
GR_UpdateActiveConfigError
Memory writing error during update of instrument
current configuration
(*)Algorithm for search of parameters for sensor calibration: if there’s only one defined parameter
it’s always used for every input (also more than one); if there’re several defined parameters, they
must correspond with specified input; in other cases, error. The calibration parameters can be
defined at the end of list of standard quantities.
The function of probes auto-recognition is a local setup, in other words the configuration is set-up
automatically and just in the instrument where this function is required. In case there’s a network of
M-Log dataloggers, it’s necessary the use of 3DOM software in order to update the configuration of
master instrument and acquire properly all quantities coming from other acquirers by radio.

5.1.2 Checkimg the power supply voltage
During the survey the instrument checks the power supply voltage constantly, in order to grant its
enough to the inner functions. The check isn’t arranged to grant the operation of the outside devices
(modem, sensors that need power supply, etc.) that already couldn’t work regularly.
The check happens every minute: the instrument acquires and checks the power supply voltage; it
must be 3,5 Vdc at least. In case it isn’t enough, M-Log closes the survey in progress and stands by.
During the stand-by it checks every minute the power supply voltage, until it’ll reach the minimum
value of 3,7 Vdc. The note “Power low” (instead of the measures list) shows the stand by condition
looking forward the right power supply. When the right voltage comes back, the survey’s re-opened
and the standard operating modes re-start.
Note: the power supply voltage is acquired and checked, even if the instrument’s configuration
doesn’t include (among the programmed measures) the corresponding acquisition measure of the
battery’s voltage. In order to store the feeding values (surveyed during the survey), the battery
voltage measure must be programmed (like proposed by 3DOM warning message).
5.2 Acquisition and calculation of measures
It is possible to acquire measures of sensors with a rate from 1 second to 12 hours; this allows a
better representation of both fast-changing quantities (wind speed), as well as slow-changing ones
(air temperature). It is possible to acquire as many as 10 measures per second.
For sensors which have to be powered, M-Log is fitted with own outputs with switched power
supply (actuators).
The instrument is able to calculate quantities deriving from measures that sample the signs from the
inputs: M-Log is fitted with a calculation library dedicated to environmental applications, also able
to carry out useful mathematical functions (see §Errore. L'origine riferimento non è stata
trovata.). M-Log is able to acquire and calculate up to a maximum of 50 total measures.
Furthermore it’s possible to program some calculated measures according to the data generated by
other calculated measures.
Program 3DOM can be used to program the measure sampling sequence: the program interface
allows choosing the sequence in which the measures are displayed; hence which is the sampling
sequence taking place during the survey. With 3DOM you can also set automatically the measure
sequence according to their acquisition rate (from the shortest to the slowest). This is important to
gather measures which, during the acquisition process, must be sampled within the shortest
intervals possible among each other (if they are allocated to only one actuator).
If configured with the same acquisition rate, the analogue channels following the first one will be
sampled about 80 ms after the previous channel. This means that as many as eight analogue
channels are sampled within a total time of 400 ms. Digital channels are instead sampled in about a
flash. In case of application with a sensor with two measures that requires an actuator, remember
that the probe must be connected on 1-2 inputs (actuator n.1) or on 3-4 inputs (actuator n.2).

5.2.1 Acquisition from sensors with serial or radio output
M-Log is able to acquire measures from sensors connected through serial port; both serial ports (if
they are present) are enabled for this function although it is preferable and advisable to use the
seirial port 2 for this application. M-Log actually supports LSI LASTEM CISS protocol (owner
communication protocol designed by LSI LASTEM and available in all sensors with
microprocessor; device for via radio reception by means of LSI LASTEM DEC301 outside
receiver).
The use of CISS protocol allows the connection to one or more LSI LASTEM sensors (even if they
have different model); every configured sensor must have an univocal network address as regards
other sensors connected on the same communication line. The connected sensors’ quantity
determines the sampling minimum slot of the instrument: consider usually 3 sensors per second (the
minimum acquisition time with 20 sensors must be set up 7 seconds at least). It is important that the
acquisition time programmed in the instrument through 3DOM application (shown by the parameter
“Update rate”) must be the same of the spontaneous communication rate programmed by the sensor
through LSM program.
The sensor can be programmed to repeat the message communication several times, in order to
improve M-Log reception reliability; one repeat is usually enough (so the message has been
transferred twice); before the arrangement of several repeats, take into consideration: the power
autonomy of the sensor (if it is powered on through battery), and the further generated traffic. This
can make worse the reception reliability (depending on the connected sensors and the programmed
acquisition slots).
The acquisition of messages from the sensors happens as follow: 3DOM application programs one
measure for each quantity that has been acquired and transferred inside the message by the sensor;
every measure is correlate to the respective sensor’s quantity by means of the sensor’s network
address, that specify: the origin sensor (in 3DOM it’s the parameter Probe ID), and the ordinal
number of the quantity inside the message; for example in case of LSI LASTEM mod. DME811
sensor (programmed by network ID = 5) can be programmed up to 5 different measures, which
correspond to the quantity: air temperature, relative humidity, surface temperature, temperature,
temperature. The quantities number and their programming order aren’t binding (for example it’s
possible program surface temperature, relative humidity), but the quantities sequence must have the
same order like in the message; in the previous example two M-Log measures must be programmed
as follow:
Quantity
Network
address
Measure
index
Surface temperature
5
3
Relative humidity
5
2
3DOM application automates some configuration operations by means of its sensors library: for
example to program the LSI LASTEM mod. DME810 sensor press key Add from the measures list
window and then select the relevant code from the available sensors list: the application knows that
sensor is serial type and so it requires the sensor’s network ID; in succession the procedure
generates all needed measures for the sampling of the sensor in the right way.

5.2.2 Acquisition from thermocouples
This feature is not available for the model ELO011.
M-Log is able to acquire the signals from many types of thermocouples. M-Log uses the internal
temperature value as reference of value of the cold junction.
In these cases it is necessary to program, by means of the 3DOM program, the measure of the
internal temperature. The measure of the internal temperature must precede, in the measure
sequence, all measures of quantities which use such reference.
5.2.3 Details about the measure acquisition process
The sampling of the signals produced by the sensors connected to the instrument's terminal board
takes place according to the following logical procedure:
1) Measurement of the electrical signal based on its type (voltage, resistance, frequency, etc.)
and its digital conversion into a 16-bit numeric value; the physical type of the sensor is
programmed through parameter Electrical measure type;
2) Data validation: during this operation the value is limited within the scale values allowed by
the physical type of measure;
3) Possible thermocouple value correction through the measure of the cold junction
temperature (internal temperature of the instrument);
4) Linearization of non linear signals based on the setting of parameter Linearization type; the
linearization may also take place through the setting of a polynominal function whose
factors are specified until 10° degree (section Linear parameter of 3DOM);
5) Recalculation of the value according to numeric parameters defined in section Parameters:
Computation of the measured quantity through the defined initial and final scale values;
Application of the calibration factor of the specific used sensor (radiometers, rain
gauges, etc.);
Selection of the logical state with reference to the analogue signal thresholds;
Measure validation after processing accompanied by error signalization if greater (by
0.5%) than the limits set in output; wind direction and relative humidity are excluded;
Linearized quantity control: the instrument produces null output when receiving null
input;
User scale limits.
All above parameters are indicated in section Measure properties in the measure modification
window of program 3DOM.
5.2.4 Acquisition from status signals
M-Log is able to acquire different types of digital status; they have to be configured for their
connection to input number 5.
Ther are 3 different signal types: frequency signals, digital status and counters.
The default configuration of datalogger has been made for:
Page 34
LSI LASTEM M-Log – User’s manual
34
give logical status = 1
In case of short circuit or 0 V
give logical status = 0
In case of opened contact or 4 V
The sensors with status output that produce voltage (i.e. they aren’t pure contacts “open/closed”)
but with variable voltage according to measured status, can be connected to M-Log through one
diode; in this way every connection is always the right one, apart from the output voltage (no
divider is required). The anode of diode must be placed on clamp F of terminal board’s entrance and
the cathode towards the sensor.
For long acquisition it’s advisable power on externally the datalogger.
5.2.5 Fast acquisition mode of the measures
For diagnostic purposes, M-Log is equipped with a function that allows the acquisition of all
sensors connected to its inputs at maximum speed (excluding the sensors connected to the serial
port or received through the radio).
In order to activate the fast acquisition mode press key and at the same time. In this
mode, the acquisition rate becomes 1 second every 10 measures and LED of the instrument will
show a particular flashing: 5 green quicly blinkings.
Please note that in this condition the instrument:
Acquires all sensors and recalculates all measures with minimum rate of 1 second every 10
measures;
Keeps switching powers used to power the sensors permanently on;
Uses up much more energy;
Produces elaborations at the programmed rate; uses a higher number of samples compared
to the normal conditions;
In this mode the green Ok LED blinks 5 times every 5 seconds.
In order to set the instrument back to its normal mode, switch it off and on again without however
pressing key and at the same time.
5.2.6 Activation of sensor control
Function valid only for M-Log with connectors (ELO009 model)
The instrument acquires the sensors rapidly thus using up little energy; hence increasing its
operative autonomy.
When enabled, this function will replace the normal acquisition process. Avoid setting a check that
is too frequent, especially in case of several fast rate measures. Do not use this function if you aim
at saving as much energy as possible. For example, in case you have programmed 8 measures with
10 seconds acquisition rate, set the Probe check rate to 1 minute or higher.
Page 35
LSI LASTEM M-Log – User’s manual
35
5.2.7 Details about calculated measures
If the instrument has been programmed to process one ore more calculated measures, the logical
process will be the following:
1) Acquisition of all primary measures that allow the estimate of calculated measures; a
calculated measure can be a primary measure for new calculated measure;
2) Collection of the value of primary measures; if at least one of these values is found to be in
error, its calculated measure will also be indicated in error;
3) Collection of the value of standard parameters, whenever used in the calculation; the value
of these parameters is decided during the configuration process and cannot therefore be
modified during the survey;
4) Execution of the estimate;
5) Allocation of the calculated value to the measure's instant datum.
The acquisition rate of a specific calculated measure is setted by 3DOM so that it may correspond to
the acquisition rate smaller than the calculated measures it depends on.
5.3 Measure elaboration
For each acquired or calculated measure it is possible to obtain statistical elaborations at a time base
from 1 second to 12 hours. The selected elaboration base is common to all quantities.
Just as with the acquisition process (see §Errore. L'origine riferimento non è stata trovata.), the
elaboration process, too, evaluates the time of the built-in clock as a multiple of the elaboration rate
in order to determine the moment in which the elaboration of the statistical data begins. For
example, if the elaboration rate were to be set to 1 hour and 30 minutes, and the current time were
15:24:01, the following elaborations would take place at 16:30:00, 18:00:00, 19:30:00, etc.; the
elaboration uses all instant data acquired or calculated in the chosen elaboration span.
The available statistical elaborations are:
Arithmetical calculations
o Instantaneous value
o Mean
o Minimum
o Maximum
o Standard deviation
o Total
o % valid data
Vectorial calculations specific for anemometric quantities
o Prevailing direction
o Resulting direction
o Resulting speed
o Direction standard deviation (sigma-teta)
o Calm wind percentage
Page 36
LSI LASTEM M-Log – User’s manual
36
It is not possible to combine arithmetical and vectorial calculations for each specific measure.
Program 3DOM can be used to program the elaboration parameters.
The instrument doesn’t have infinite process capacity: it depends on the number of acquired and
calculated measures, on programmed actuation algorithms, on processings configured for each
measure, and on continuous communications between the instruments and the outside devices; all
these parameters cannot be programmed at the same time up to their available maximum, because
the instrument could have wrong operation. The instrument has right operation in the following
heavy duty condition:
All analogue and digital inputs configured with measures of resistance, tension, state and
frequency (4 kHz); every input sampled with 1 second rate;
Six measures configured like measures calculated with several algorithms;
The remaining measures (up to 50 measures) sampled by LSI CISS sensors with
transmission every 10 seconds;
Each measure is elaborated every 30 seconds with minimum, medium and maximum value
statistics and standard deviation;
All 10 active actuation logics configured with different algorithms and by the use of
acquired and calculated measures;
Serial communication constantly activated on both communication ports at maximum bit
rate.
It’s possible to relax some parameters in this configuration (for example the measures total number
or the active actuation logics number) in order to obtain best performances in other cases (for
example the measures activation slot)

5.4 Storing elaborated data
M-Log stores the calculated statistical processings (elaborated data) in the 2-MB internal memory; a
part of this memory (128 kB) is used for configuration information and other internal information;
the real capacity is therefore slightly less than the total storage capacity.
Data storage takes place circularly; once the memory is full, the new data will replace old ones.
By sending a new configuration to the instrument, all data so far stored will be cancelled; this
happens because the new configuration information might be potentially not in tune with them, and
the PC might misinterpret them.
The instrument stores the data in the internal memory only when a data page is full; the dimension
of this page equals to 256 bytes; therefore the instrument might store the data only after several
sequences of elaboration; this depends on the programmed elaboration rate, on the number of active
measures and, for each one of them, on the selected elaboration elements. Please note that by
switching off the instrument, some elaborated data inside the data page and those not definitely
stored might be lost; for this reason we advise transferring the elaborations which have not yet been
transmitted to the PC before switching off M-Log.
5.4.1 Memory autonomy
Depending on the chosen configuration (measures, types of elaboration for each measure and
acquisition rate) the instrument will work somewhat autonomously as far as the maximum storage
time is concerned, without replacing old data with new ones. The calculation of the time dimension
of the maximum number of storable data is as follows:
A = K / (86400 / RE * NE)
where:
A = number of days of autonomy of the data memory;
K = value subordinate on the size of the used memory; for the 2 MB internal memory, K=386048;
RE = elaboration rate expressed in seconds;
NE = total number of elaboration’s elements programmed for all measures.
Page 38
LSI LASTEM M-Log – User’s manual
38
Note: the duration of memory measured in days (according with the current configuration) is
displayed on PC after sending the configuration through 3DOM software.
5.5 Actuation logics
M-Log has got an actuation logics library. It’s useful to switch-on all type devices (alarms, solenoid
valves, motors) according the surveyed parameters in surrounding environment. The actuation
logics are based on the instantaneous value of the acquired and calculated measures. They can be
programmed up to 10 calculation algorithms, that use same or different logics. One or more
algorithms can be combined in two differed modes , in order to switch-on the selected actuator:
1) All algorithms must be in alarm at the same time (AND logic);
2) One algorithm can be in alarm at least (OR logic).
The actuator’s switch-on logic can operate according to low power consumption mode (the actuator
is usually deactivated, and starts in case of alarm), or according to safety mode (the actuator is
usually activated, and it shuts-down in case of alarm). Summarizing explanation in the table below.
Operating logic
State
Actuator
Low consumption mode
No alarm
Actuation output switched-off
Alarm
Actuation output switched-on
Safety mode
No alarm
Actuation output switched-on
Alarm
Actuation output switched-off
In case of one or several measures’ error (for example owing to sensor breaking, no-scale
acquisition, or disconnected cable) it doesn’t modify the present state of the actuator piloted by the
logic that uses the same measures.
The manual activation and deactivation of the actuators, performed by the user directly on the
instrument from Diagnostic window type 4 (see §4.3.4), does not affect the actuation logics. The
actuation logic deactivates the actuator only if it has previously activated from the logic itself.
The actuation logic begins operation after the first activation of the actuator, even if this occurs
temporally after the deactivation.
The programming of the actuation logics happen by means of the 3DOM program according to two
different phases:
1) Selection of the logics and their calculation parameters (section Logics);
2) Selection of the actuation outputs and their AND or OR modes correlation with the present
logics (section Actuators); note that the same logic can be combined with other different
logics several times, in order to switch over different actuators.
For M-Log with connector inputs (ELO009 series) may only be used the following actuation logics:
Cyclic timer or with data/hour start/stop;
Threshold value compare.
Page 39
LSI LASTEM M-Log – User’s manual
39
For M-Log with terminal board inputs (ELO007 and ELO008 series) may be used all the actuation
logics available from 3DOM software.
The model ELO011 has only the actuator 3 on the serial line 1.
5.5.1 Eolic alarm
(Logic used only for M-Log with terminal board inputs – ELO007 and ELO008 series.)
The logic uses a wind direction measure to establish the condition of a wind position in a specified
sector for a predefined time. Can be set:
The measure that samples wind direction (degrees);
The starting angle (extreme included) of the direction sector;
The ending angle (extreme included) of the direction sector;
The continuous permanence time of the wind direction inside the defined sector in order to
detect the alarm condition;
The continuous permanence time of the wind direction outside the defined sector in order to
detect the end of the alarm condition.
Both times can be set from 0 seconds to 12 hours; if both times are set to zero, the wind direction in
or out conditions inside the sector are immediately detected.
It is possible to join this logic with an another logic of threshold bypass type (see §Errore.
L'origine riferimento non è stata trovata.) applied to a wind speed measure: in this way it’s
possible to refine further the alarm activation (i.e. to activate the alarm when the wind is more than
5 m/s for at least 3 minutes and inside the Est sector of 45 degree for at least 1 minute).
5.5.2 Evaporimeter filling
(Logic used only for M-Log with terminal board inputs – ELO007, ELO008 and ELO011 series)
The logic uses a water level probe inside the evaporimeter to establish the need for filling up it.
Can be set:
The measure that samples the water level;
The filling-up start time (it’s recommended the automatic filling-up programmed in the
morning, before the sunrise, in order to avoid temperature changing that could alter the
evaporation measure);
The maximum filling-up time, useful to avoid flooding in case the water level sensor is
broken or surveys a wrong measure;
The maximum water level that determines the stop of the filling;
The minimum water level, under that the need for the evaporimeter filling-up (at the defined
time), is detected. To obtain the right evaporation keep the evaporimetric basin always
filled. Therefore set the minimum level like the maximum level, because, in case of too low
water level, the shade of the walls on the surface of the water doesn’t allow the right
evaporation in the morning and in the evening.
5.5.3 Start precipitation alarm
(Logic used only for M-Log with terminal board inputs – ELO007 and ELO008 series)
The logic uses a measure connected to a rain gauge to detect the start precipitation conditions.
Page 40
LSI LASTEM M-Log – User’s manual
40
Can be set:
The measure that samples the precipitation;
The minimum time T1 after the first precipitation detection by means of the rain gauge
(instantaneous value > 0);
The minimum time T2 that must pass after the precipitation detection, meanwhile no
precipitation is detected (no precipitation detection by the inner sensor of the rain gauge), to
determinate the end precipitation condition;
The minimum precipitation quantity that determines the start of the precipitation condition.
The alarm condition is detected when T1 time is passed after the first precipitation detection (and
it’s raining again), or is reached the specified rain quantity; anyway if T2 time is passed without any
precipitation detection, the system goes to no alarm condition.
5.5.4 Flood alarm
(Logic used only for M-Log with terminal board inputs – ELO007, ELO008 and ELO011 series)
The logic uses a measure connected to a rain gauge to detect flooding conditions. Can be set:
The measure that surveys the precipitation;
The maximum precipitation quantity in a defined period;
The minimum precipitation quantity in the same period;
The length of alarm or not alarm period.
The alarm condition is detected when, within the specified period that starts from the first
precipitation event, the maximum precipitation quantity is exceeded; from alarm condition
beginning or at the end of the first period, are managed new periods and for each of them the rain
totalization starts from zero; for each new period, if the rain fall quantity returns below the specified
minimum value, the system returns in no alarm condition.
5.5.5 Threshold value compare
The logic detects value overflow or underflow by one or more measures (both univocally and
simultaneously). To the threshold values can be applied a further hysteresis value; this can avoid
continuous alarm state changes in case the measure value moves nearly around the threshold value.
The comparison logics are the following:
Greater than: alarm in case the measure value if greater than the threshold value added to
the hysteresis; return to no alarm condition when the measure value in lesser than the
threshold value minus the hysteresis; i.e. threshold value=4.0 and hysteresis=0.2 (alarm in
shaded area):
Page 41
LSI LASTEM M-Log – User’s manual
41
Lesser than: alarm in case the measure value is lesser than the threshold value minus the
hysteresis; return to no alarm condition when the measure value is greater than the threshold
value added to the hysteresis; i.e. threshold value=4.0 and hysteresis=0.2 (alarm in shaded
areas):
Page 42
LSI LASTEM M-Log – User’s manual
42
Included: alarm in case the measure value if greater than the minimum threshold value and
at the same time lesser than the maximum threshold value; return to no alarm condition
when the measure value is lesser than the minimum threshold value or greater than the
maximum threshold; hysteresis is used like shown in the following example: threshold
values=2.0 and 4.0 and hysteresis=0.2 (alarm in shaded areas):
Excluded: alarm in case the measure value if lesser than the minimum threshold or greater
than the maximum threshold; return to no alarm condition when the measure value is greater
than the minimum threshold and at the same time lesser than the maximum threshold;
hysteresis is used like shown in the following example: threshold values=2.0 and 4.0 and
hysteresis=0.2 (alarm in shaded areas):
Page 43
LSI LASTEM M-Log – User’s manual
43
Threshold value compare algorithm can be applied to one or more measures; in the last case all used
measures must be consecutively ordered (the list cannot include any measures that shouldn’t be
considered in the comparing), because the logic programming needs the ordinal numbers of the first
and last measure. This logic can be programmed to detect the alarm condition only if all measures
(that belongs to the selected set) or alternatively only one of them are contemporary over the stated
limit.
Furthermore it’s possible specify a minimum time (during that the measure stays over the set
threshold value) to enter into the alarm condition and a minimum time to exit from the alarm
condition. It can be done applying the algorithm to only one measure (i.e. it isn’t possible to
program the minimum times if two or more measures have been selected).
5.5.6 Timer
The timer logic allows: to activate or deactivate the actuator in two different times in the day, or
alternatively to define a timed cycle on/off status. Can be set:
Timer type (cyclic or time);
The power-on delay after the initial instant determined by the cycle;
If timer type is cyclic, the on and off statuses duration; the first cycle starts in the day time
when the instrument clock time, divided by the sum of the two durations, returns zero as
remainder; in this way the first cycle starts in a precise day time, not at any moment (i.e. if
has been programmed 15 minutes On period duration, and 45 minutes Off period duration,
the first cycle starts at the first hour and zero minutes after the instrument survey is started);
the next cycles happen at set on/off times.
If timer type is not cyclic, the day time of power on the actuator, and the day time of power
off.
Page 44
LSI LASTEM M-Log – User’s manual
44
This logic is joinable with other logics in AND mode, for example to allow the alarms activation
only in specified hours of the day.
5.5.7 Snow level alarm
(Logic used only for M-Log with terminal board inputs – ELO007 and ELO008 series)
The logic detects excessive snow fall conditions in indeterminate time period; the alarms condition
stays active during programmable time; at the end of this alarm period the snow level starts to be
counted from the actual level; if during the alarm condition the snow level decreases (owing to
melting or autocompression), the snow level start value (used like reference value in the next delta
calculation) updates accordingly. Can be set:
The measure that samples the snow level;
The maximum delta (centimeters), over that the system goes in alarm condition;
The alarm duration before its automatic reset.
5.5.8 System error
The logic sets an alarm when the instrument detects and internal malfunction. All errors are
detected as specified in §Errore. L'origine riferimento non è stata trovata..
Page 45
LSI LASTEM M-Log – User’s manual

5.6 Communication modes
M-Log has got different communication devices, that can be used to extend the connection
capacities and modes to systems for data collection:
RS232 serial port: at least one port (equipped with a double connector for applications
where you want to interface M-Log with a DCE device or a DTE device) for each M-Log
datalogger; two serial ports are available for ELO008 and ELO009 models; (see §Errore.
L'origine riferimento non è stata trovata.)
Xxx line driver: it lengthens the cable for serial connection up to 1 km or more; the
connection speed is function of covered distance; you have always to install a couple of line
drivers: one of them must be connected to RS232 serial port of M-Log, the other one must
be connected to PC;
RS232/Ethernet converter (code LSI LASTEM DEA550): it can be used with instruments
equipped with RS232 serial line; it allows the communication using Ethernet LAN/WAN
net, so virtually of any length; particularly ELO007 model has this converter built-in;
GSM DEA714 Modem: it uses GSM network for connection to remote instruments; 9600
bps connection speed; it can be connected to serial port of M-Log; (see §Errore. L'origine
riferimento non è stata trovata.)
GSM/GPRS Modem (code LSI LASTEM DEA717 and DEA718): it uses GPRS packets
transmission in order to allow the permanent transmission (with transmission rate according
to choice) and rating according to traffic; it can be connected to serial port of M-Log and it’s
an application valid only for datalogger equipped with terminal board (series ELO007 e
ELO008); (see §5.6.2)
Bluetooth Adapter (code LSI LASTEM DEA300): it can be connected to serial port of M-
Log (it’s advisable use port serial 1, as able to handle sending large data frames, in excess of
128 B);
External radio devices.
5.6.1 RS232 serial port
M-Log communicates with PC through 9 poles male/female not-reversing serial cable.
M-Log implements a particular system for activation of communication port: after 8 seconds of noreception or no-transmission, the consumption goes down to first saving; after further 22 seconds
the consumption goes down to minimum values. If you don’t query M-Log continually, it
communicates using very low energy consumption.
Every instrument uses a net address, that consists of a number with value included between 1
(default) and 200. If the instrument has been connected through network (radio) with other
instruments, it’s necessary to modify the address. The PC programs use the address of each definite
instrument to select M-Log for sending of communication messages.
M-Log is compatible with LSI LASTEM sensors family equipped with CISS protocol. So it can be
used in existing networks of LSI LASTEM cordless sensors, that make reference to E-Log, R-Log,
Babuc ABC or receivers connected to PC directly. In this case M-Log can be programmed for
spontaneous transmission, through serial port, of instantaneous data of acquired and calculated
measurements; this parameter is available in mask for modification of 3DOM communication
Page 46
LSI LASTEM M-Log – User’s manual
46
parameters, and it’s called automatic transmission rate. In this mode M-Log results like LSI CISS
multi-channel sensor and so its measurements can be received by an other M-Log.
In addition to the CISS protocol, M-Log is able to manage, through serial port 2, other protocols:
TTY (see §5.6.4);
Modbus (see §5.6.5) ;
Gill anemometer;
Giletta GIL-D-I Ice sensor (only if it’s required);
Aeroqual gas analyser;
Hydrolab;
Lufft UMB sensor (only if it’s required);
Climatronics sensor.
A GSM or GPRS telephonic modem can be connected to serial port; in this case, if you want reduce
the energy consumption of modem, it’s possible follow the instruction of §5.7. Anyway, if removed
appropriately, the use of a modem doesn’t block the local communications with M-Log, connecting
PC to serial port of instrument directly.
Note: in case PC has to execute any communication with the instrument through serial port, and the
latter has been programmed for spontaneous transmission of data at frequent rate (intervals shorter
than 10 s), PC could meet some difficulties to start first communication; so it could be necessary to
start operation several times. After the reception of message, M-Log deactivates spontaneous
communication for 1 minute, in order to make further communications with PC easier.
M-Log manages the flow check according to two choices (none, only RTS) that can be selected
through configuration from 3DOM (see §4.4.4.3 of manual SWUM_00339 inside CD of LSI
LASTEM – MW6501 products).

5.6.2.2 XPORT configuration (internal Ethernet port)
For right operation, each M-Log must be configured according to special setups (for TCP/IP
protocol) through DeviceInstaller of Lantronics software, available in DVD LSI LASTEM products
(MW6501) in “Install\Support\Lantronix” folder or downloadable from Lantronics website
http://www.lantronix.com/support/downloads.html
To configure Ethernet port, follow the instruction below:
1. Connect LAN cable in proper port on top panel of M-Log and check the flashing LED on
the port, indicating the presence of the network.
2. Open DeviceInstaller software of Lantronics and following window will be displayed:
3. Press Search and identify the computer device connected to LAN. After some seconds, if
LAN connection is operating properly, the instrument is recognized and listed among the
available ones. In case of several instruments, it’s possible to determine each model
according to hexadecimal numeric code written on label placed on bottom side of box.

5.6.3 Data trasmission through GPRS connection
GPRS data transmission system consists of the following parts:
One or more M-Log instruments (only ELO007, ELO008 and ELO011 models);
One modem GPRS LSI LASTEM Mod. DEA717 or DEA718 for each M-log, connected
through ELA110 or ELA112 cable; the modem SIM card must be able to GPRS data
transmission and the request of PIN code must be disable;
Page 51
LSI LASTEM M-Log – User’s manual
51
One PC server with Windows operating system (Window XP or next version, Windows
Server 2003 or next version), connected to Internet with a public IP address;
LSI LASTEM CommNetEG code BSZ306.2 program with use licence enabled for GPRS
connections (only for transmission through TCP socket).
M-Log must be configured through 3DOM program, in order to use GPRS modem and transfer the
elaborated data with selected timing; the GPRS modem can be used only with serial port 1. In the
configuration through 3DOM software, remember to enable with Yes the field Modem powered with
actuator in the Serial communication port 1 window when the modem is powered using actuator 3
(recommended solution).
GPRS connection happens according to the spontaneous transmission rate programmed inside the
system; therefore it happens according to the programmed timing (on the initiative of the
instrument); you can also make a manual data transfer by pressing the button . The remote
computer (that collects the data) consists of one TCP server, set on IP public address. The address
of this server has been programmed inside GPRS modem connected to M-Log.
There are two different transmission’s modes:
Through TCP socket;
Through FTP protocol.
The TCP socket connection allows the use of minimum quantity of IP packets, and for this reason
it’s cheaper than FTP protocol. Moreover one server (no special software installed in it) can transfer
the data through TCP protocol.
In addition to the above-described parameters, set the following parameters through 3DOM
software in according to the selected transmission’s mode:
for TCP mode, select Switched off and on in case of failure option in Serial communication port
1 window;
for FTP mode, select Power on/off due to actuation logic option in Serial communication port 1
window to set the modem to switch off once a day. Then configure an actuation logic for leave
the modem turned on all day except for a minute that will remain turned off; it is advisable to
turn on the modem at least two minutes before the transmission.
M-Log will transfer the data to the operative centre at set timing. The parameters of the operative
centre (IP address, IP port, user name, etc) have been specified inside config.ini configuration file
(stored inside GPRS modem). In case of transmission through TCP socket the operative centre must
be equipped with LSI LASTEM CommNetEG code BSZ306.2 program. In case of transmission
through FTP protocol, one FTP server must be available and working.

5.6.4 TTY Protocol
TTY protocol allows: the inquiry of the data acquired by simplified way (also from terminal), or the
transmission of the instantaneous data of the measures by spontaneous mode.
Page 53

53
For more informations about TTY protocol see INSTUM_00728_en manual reported on LSI
LASTEM products DVD (MW6501).
5.6.5 Modbus Protocol
Modbus is a serial communication protocol used in industrial circle; it allows the communication
between one master (usually PC) and one or more slave (devices for measurement, check or PLC)
connected to the same network. Modbus sets-up the master and slave’s modes to start and stop the
communication, it settles the modes for messages exchange and errors identifying too. Only master
can start the communication.
There are two protocol versions: one serial version (RS-232 or RS-485) and one Ethernet version.
The serial version includes two different communication modes: one RTU mode (where the data are
packet in Hexadecimal format) and one ASCII mode (where the data can be easily read). In
Ethernet version (like the RTU version) the protocol’s packets are inside TCP/IP packets.
Every network device has its univocal address. A Modbus command includes the Modbus address
of the instrument which want communicate with. Only this instrument will answer to the command,
even though all instrument receive it. All Modbus commands include check information, that assure
the correct reception of the command. The base commands can ask to a slave to change one value
into one of its statuses or to return one or more values included into its registers.
E-Log looks like slave and implements part of the industrial Modbus protocol in RTU version on
serial port RS-232.
For more informations about Modbus protocol see INSTUM_00728_en manual reported on LSI
LASTEM products DVD (MW6501).
5.6.6 M-Log connected like master-slave mode
It’s possible use two M-Log cascading, that is master/slave mode, especially when the number of
physical inputs required by the application is higher than the number of physical inputs supplied by
one M-Log datalogger. So we call master instrument the M-Log connected to host through direct
connection or through communication apparatus, while slave instrument is connected only to master
instrument. Using this configuration mode the slave instrument is a real multi-parametric serial
sensor (from master datalogger’s point of view).
In order to configure the system like master/slave mode follow the instructions below:
1. Physical connection:
Connect the serial port 2 of both dataloggers using null modem cable (LSI LASTEM
code ELA121) or serial cable (LSI LASTEM code ELA105) with null modem
adapter;
Connect the serial port 1 of M-Log master with the host through direct connection or
through one communication apparatus.
2. During configuration through 3DOM software:
configure the slave instrument using only its measures (i.e. the measures that take-up
their physical inputs) and don’t setup any elaborations;
Page 54
LSI LASTEM M-Log – User’s manual
54
configure the master instrument using both its measures (marked with symbol )
and the serial measures (marked with symbol ) coming from slave instrument; the
serial measurements coming from slave instrument can be imported directly from
Import function in 3DOM software selecting the correct configuration to be
imported;
check the agreement between the measures acquired from slave and the serial
measures received from master (most of all the values of Sensor’s Protocol Address
and Index of measure in the sensor); the uncorrect agreement prevent the master
instrument from acquiring correctly;
for M-Log master configure in serial communication parameters of port 2: Protocol
Type =Native and Velocity=57600;
for M-Log slave configure in serial communication parameters of port 2: Network
Address=1, Spontaneous transmission Rate ≠0 (input one rate lower than the
acquisition rate of fast serial measure set up on master; we recommend the input of
slave’s transmission rate half of master’s acquisition rate) and Message transmission
repetitions ≥1; see the following example:
for serial measures, that have to be received from master instrument, set up the
Sensor’s Protocol Address equal Instrument’s Network Address selected for serial
communication port 2 of slave instrument; recommended default value is 1.
So it’ll be possible the remote modification (through 3DOM software ) of instrument’s
configuration, but it won’t be possible the remote modification of slave’s configuration

5.7 Operating of low energetic consumption
There isn’t a very configuration for low energetic consumption mode.
Anyway in order to optimize energy consumption, proceed as follows:
Use the highest possible value to program the acquisition rate of the measures, according to
the dynamic feature of the quantity's signal to be sampled (see §Errore. L'origine
riferimento non è stata trovata.);
Keep the actuation time to energize the sensors low without compromising the reliability of
the measure (see §Errore. L'origine riferimento non è stata trovata.);
Use the lowest possible acquisition time required to, however, have the sensor send the
measured signal in a correct manner (see §Errore. L'origine riferimento non è stata
trovata.);
Use a high rate, and only if necessary, to program the rate for probe control (see §5.2.6);
Switch the display off manually or program it to automatically shut off by itself (see §4.3.5);
the display can be turned off by pressing of button, while displaying the mask of
measures;
Disable the fast acquisition mode of the measures which was possibly enabled while the
instrument was switched on (see §5.2.5).
Cancel not-used actuation logics (see §Errore. L'origine riferimento non è stata
trovata.);
Manage modem switch on through actuator 3 (programmed with timed logic), or
programming GPRS communication through modem activation;
In case of sensors or telephone modems fed continuously, don’t use instrument’s batteries,
but use other ones (if possible). In this way the instrument can operate even if modem and/or
sensors aren’t fed, and so they aren’t operating;
ATTENTION: Default configuration programmed on instrument is not the one of lowest energetic
consumption.

(*) Calculated measures available only for M-Log datalogger with firmware from 2.3 version;
calculated measures associated with 3DOM software from 3.8 version.
These measure are set a fixed update time of 1 second: the update of value of calculated measure on
the actuator is always 1 second delay compared to the status recorded by internal actuation logic.
Now is therefore possible to process and record the actuator status or display it as an instantaneous
value without having to carry the electrical signal of the actuator in an input of the datalogger. Now
it is also possible make complex algorithms through a combination of actuation logics status with
other calculated measures (typically addition and multiplication), overcoming the limits of the use
of a single operator (AND and OR) and giving the inputs for the acquisition of real sensors.
With 3DOM you can choose which quantities to have the instrument calculate and select the direct
measures which allow their calculation.
Some calculations, frequently used in agro-meteorology, such as wind direction or integral
radiation, are easily obtained from the integral mathematical calculation.

6.3 Error messages
M-Log indicates errors by triggering the red led Err located on the instrument's keyboard: the kinds
of errors, listed in the following table, are indicated by the blinking modes.
Number of
blinkings
Type of problem
Troubleshooting
1
Data memory access
Try to transfer the data elaborated by the instrument;
then send the configuration again to the instrument
using 3DOM (see §Errore. L'origine riferimento non
è stata trovata.); if the error occurs again, contact LSI
LASTEM technical support
3
Acquisition from
sensors
Use 3DOM to check the congruence of the acquisition
parameters of the measures in the current
configuration; send the configuration again to the
instrument (see §Errore. L'origine riferimento non è
stata trovata.); should a new error occur, contact LSI
LASTEM technical support for assistance including the
current configuration file
4
Parameter configuration
Transfer the data elaborated by the instrument; then
send the configuration again to the instrument using
3DOM (see §Errore. L'origine riferimento non è
stata trovata.); if the error occurs again, contact LSI
LASTEM technical support for assistance including the
current configuration file
5
Search data in memory
If the error occurs immediately after switching on the
instrument, reset the error and continue using the
instrument as usual; should a new error occur while
operating the instrument with no communication with
the PC, contact LSI LASTEM technical support;
should the error occur while requesting the elaboration
in memory by the program 3DOM, try requesting the
data again using a different date/time (try using a
previous date first; should a new error occur, try later
dates); should the error persist, switch the instrument
on and off and request all data indicating a date/time
definitely prior to the first date in memory; upon
completion of the data transfer, cancel them; should the
error occur again send the configuration of the
instrument to LSI LASTEM technical support
describing the problem.
6
Protocol CISS
Use 3DOM to check the congruence of contents
parameters in the current configuration; send the
configuration again to the instrument (see §Errore.
L'origine riferimento non è stata trovata.); should a
new error occur, contact LSI LASTEM technical
support for assistance including the current
configuration file
When the instrument finds an error, it also indicates it as follows:

1) By activating the digital signal of the error;
2) By displaying the numeric value of the error found: the error code appears on the
visualization window of the diagnostic data type 1; the numeric code can actually indicate
more than one error; the displayed value is expressed with a hexadecimal number; the errors
that correspond to the value that appears on the display can be easily interpreted by means of
program 3DOM (menu Instruments);
3) By communicating with program 3DOM: while the instrument transfers the elaborations or
sends the configuration data, the programs may show the code of the error found by the
instrument.
6.3.1 Disabling error signalization
There are two possibilities to disable error signalization:
1) Press key and while the error code is being displayed in the diagnostic window
type 1 to reset the error (it will however remain on the display when you leave and call the
diagnostic window);
2) While the data is being transferred between instrument and PC: in this case the instrument
resets the error since it considers that the error has already been found by the person using
the computer.
In both cases the reset operation will locally switch off the optical indicator Err, eliminate the error
number from the diagnostic window type 1 and disable the signal in effector’s output (if
programmed by respective actuation logic). The error reset will remain until the instrument finds a
new possible error; in this case the instrument will activate the error signalization mode again as
previously described.
6.3.2 Error found in measure
The values indicated by the measures (instantaneous values) may indicate the error status (Err), in
the following conditions:
If the measure is acquired:
o Programming of a measure incompatible with the type of signal to be measured
(electrical type selected, linearization type, scale recalculation parameter, etc.);
o Sensor is interrupted or is not correctly connected to the terminal board (see
§Errore. L'origine riferimento non è stata trovata.);
o If the sensor is powered by an energized output, the starting time might not be
enough;
o The electrical input signal (to the instrument) is out of scale;
o In case of thermocouple measure, the cold junction temperature (internal
temperature) might not be programmed;
o In case of measure acquired from serial port: no valid message has been detected
coming from the sensor during time corresponding to more then treble set
acquisition rate.
If the measure is calculated:
o Out-of-scale or in-error value from one or more dependant measures allocated to the
measure to be calculated;
Page 63
LSI LASTEM M-Log – User’s manual
63
o Error in output to the algorithm of the calculated measure;
When the number to be displayed is < -999999 or > 9999999, E-Log points out the anomaly of
measure in overflow with “Overfl.” error status.
6.3.3 Low battery signalization
The low battery signalization occurs on datalogger through three times blinking of LED ▄-Err; the
error LED blinking disappears automatically in instrument when the battery becomes charged.
In the following table there are values of battery voltage to trigger the alarm condition:
Condition
Battery voltage
Minimum voltage of battery to “keep alive” the instrument
3,3 V
Minimum voltage of battery to trigger the alarm condition
3,5 V
Minimum voltage of battery to operate with the survey
3,7 V
6.4 Instrument maintenance
M-Log does not require special maintenance interventions when installed according to the general
safety rules indicated in §Errore. L'origine riferimento non è stata trovata..
However, we recommend that LSI LASTEM staff carries out periodical check of whole installation
(M-Log and sensors connected to it) at regular intervals in order to point out and correct possible
measurement errors.
