Measurement Timing
The timing of measurements is determined by the cycle selected during
configuration (Normal or Fast Cycle):
zNormal Cycle means that the scan cycle duration is fixed.
zWith the Fast Cycle, however, the system only scans the channels designated as
being In Use. The scan cycle duration is therefore proportional to the number of
channels In Use.
The cycle time values are based on the cycle selected:
NOTE: Module cycle is not synchronized with the PLC cycle. At the beginning of
each PLC cycle, each channel value is taken into account. If the MAST/FAST task
cycle time is less than the module’s cycle time, some values will not have changed.
Overflow/Underflow Control
Module BMX AMI 0810 allows the user to select between 6 voltage or current
ranges for each input.
This option for each channel have to be configured in configuration windows. Upper
and lower tolerance detection are always active regardless of overflow/underflow
control.
Depending on the range selected the module checks for overflow, it verifies that the
measurement falls between a lower and an upper threshold:

The values of the thresholds are configurable independently from one another. They
may assume integer values between the following limits:

range
Upper Tolerance Area varies between the values included between the
maximum value for the range (for instance: +10 V
for the +/-10 V range) and the upper threshold
Lower Tolerance Area varies between the values included between the
minimum value for the range (for instance: -10 V for
the +/-10 V range) and the lower threshold

Measurement Display
Measurements may be displayed using standardized display (in %, to two decimal
places):
It is also possible to define the range of values within which measurements are
expressed, by selecting:
zthe lower threshold corresponding to the minimum value for the range: 0 % (or -
100.00 %).
zthe upper threshold corresponding to the maximum value for the range (+100.00
%).
The lower and upper thresholds must be integers between -32,768 and +32,767.
For example, imagine a conditioner providing pressure data on a 4-20 mA loop, with
4 mA corresponding to 3,200 millibar and 20 mA corresponding to 9,600 millibar.
You have the option of choosing the User format, by setting the following lower and
upper thresholds:
3,200 for 3,200 millibar as the lower threshold
9,600 for 9,600 millibar as the upper threshold
Values transmitted to the program vary between 3,200 (= 4 mA) and 9,600 (=
20 mA).
Measurement Filtering
The type of filtering performed by the system is called "first order filtering". The
filtering coefficient can be modified from a programming console or via the program.
The mathematical formula used is as follows:
where:
α= efficiency of the filter
Measf(n) = measurement filtered at moment n
Measf(n-1) = measurement filtered at moment n-1
Valb(n) = gross value at moment n

You may configure the filtering value from 7 possibilities (from 0 to 6). This value
may be changed even when the application is in RUN mode.
NOTE: Filtering may be accessed in Normal or Fast Cycle.
The filtering values depend on the T configuration cycle (where T = cycle time of
5 ms in standard mode):
Sensor Alignment
The process of "alignment" consists in eliminating a systematic offset observed with
a given sensor, around a specific operating point. This operation compensates for
an error linked to the process. Replacing a module does not therefore require a new
alignment. However, replacing the sensor or changing the sensor’s operating point
does require a new alignment.

The alignment value is editable from a programming console, even if the program is
in RUN Mode. For each input channel, you can:
zview and modify the desired measurement value
zsave the alignment value
zdetermine whether the channel already has an alignment
The alignment offset may also be modified through programming.
Channel alignment is performed on the channel in standard operating mode, without
any effect on the channel’s operating modes.
The maximum offset between measured value and desired (aligned) value may not
exceed +/-1.500.
NOTE: To align several analog channels on the BMX ART/AMO/AMI/AMM
modules, we recommand proceeding channel by channel. Test each channel after
alignment before moving to the next channel in order to apply the parameters
correctly.

Wiring Precautions
Introduction
In order to protect the signal from outside interference induced in series mode and
interference in common mode, we recommend that you take the following
precautions.
Cable Shielding
Connect the cable shielding to the grounding bar. Clamp the shielding to the
grounding bar on the module side. Use the BMX XSP 0400/0600/0800/1200
electromagnetic protection kit
(see Modicon M340 Using Unity Pro, Processors,
Racks, and Power Supply Modules, Setup Manual)
to connect the shielding.

4 To sensors
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
While mounting / removing the modules:
zmake sure that each terminal block is still connected to the shield bar and
zdisconnect voltage supplying sensors and pre-actuators.
Failure to follow these instructions will result in death or serious injury.

Reference of Sensors in Relation to the Ground
In order for the acquisition system to operate correctly, it is recommended to take in
account the following precautions:
zsensors must be close together (a few meters)
zall sensors must be referenced to a single point, which is connected to the PLC’s
ground

Using the Sensors Referenced in Relation to the Ground
The sensors are connected as indicated in the following diagram:
If the sensors are referenced in relation to the ground, this may in some cases return
a remote ground potential to the terminal block. It is therefore essential to follow the
following rules:
zThe potential must be less than the permitted low voltage: for example, 30 Vrms
or 42.4 VDC.
zSetting a sensor point to a reference potential generates a leakage current. You
must therefore check that all leakage currents generated do not disturb the
system.
NOTE: Sensors and other peripherals may be connected to a grounding point some
distance from the module. Such remote ground references may carry considerable
potential differences with respect to local ground. Induced currents do not affect the
measurement or integrity of the system.
DANGER
HAZARD OF ELECTRIC SHOCK
Ensure that sensors and others peripherals are not exposed through grounding
points to voltage potential greater than acceptable limits.
Failure to follow these instructions will result in death or serious injury.

Electromagnetic Hazard Instructions
CAUTION
UNEXPECTED BEHAVIOR OF APPLICATION
Follow those instructions to reduce electromagnetic perturbations:
zuse the BMX XSP 0400/0600/0800/1200 electromagnetic protection kit
(see Modicon M340 Using Unity Pro, Processors, Racks, and Power Supply
Modules, Setup Manual)
to connect the shielding.
Electromagnetic perturbations may lead to an unexpected behavior of the
application.
Failure to follow these instructions can result in injury or equipment damage.

Wiring Accessories
Two cords BMXFTA150 (1.5 m (4.92 ft)) and BMXFTA300 (3 m (9.84 ft)) are
provided to connect the module with Telefast interfaces ABE-7CPA02
(see page 89)
, ABE-7CPA31
(see page 89)
or ABE-7CPA31E
(see page 89)
.
In case HART information is part of the signal to be measured, a Telefast interface
ABE-7CPA31E
(see page 89)
has to be used in order to filter this information that
would disrupt the analog value.
