 Safety instructions

1 Safety instructions
Intended use
The amplifier system is to be used exclusively for measurement tasks and
directly related control tasks. Use for any purpose other than the above is
deemed to be non-designated use.
In the interests of safety, the device should only be operated as described in
the operating manuals. It is also essential to comply with the legal and
safety requirements for the relevant application during use. The same ap­
plies to the use of accessories.
Each time, before starting up the equipment, you must first run a project
planning and risk analysis that takes into account all the safety aspects of
automation technology. This particularly concerns personal and machine
protection.
Additional safety precautions must be taken in plants where malfunctions
could cause major damage, loss of data or even personal injury. In the
event of a fault, these precautions establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling,
limit switches, etc.

General dangers of failing to follow the safety instructions

The amplifier system is a state of the art unit and as such is reliable. The
device may give rise to residual dangers if it is inappropriately installed and
operated by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance
or repair of the device must have read and understood the operating
manuals and in particular the technical safety instructions.

Residual dangers
The scope of supply and performance of the amplifier system covers only a
small area of measurement technology. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety
engineering considerations of measurement technology in such a way as to
minimize residual dangers. On-site regulations must be complied with at all
times. There must be reference to the residual dangers connected with
measurement technology.

MGCplus A0534-30.0 HBM: public 11

Safety instructions

After making settings and carrying out activities that are password-
protected, you must make sure that any controls that may be connected re­
main in a safe condition until the switching performance of the amplifier
system has been tested.

Working safely
The supply voltage connection, as well as the signal and sense leads, must
be installed in such a way that electromagnetic interference does not ad­
versely affect device functionality (HBM recommendation: "Greenline
shielding design", can be downloaded from http://www.hbm.com/Greenline).
Automation equipment and devices must be designed in such a way that
adequate protection or locking against unintentional actuation is provided
(access checks, password protection, etc.).
When devices are working in a network, these networks must be designed
in such a way that malfunctions in individual nodes can be detected and
shut down.
Safety precautions must be taken both in terms of hardware and software,
so that a line break or other interruptions to signal transmission, such as via
the bus interfaces, do not cause undefined states or loss of data in the auto­
mation device.
Error messages should only be acknowledged once the cause of the error is
removed and there is no further danger.

Conversions and modifications

The amplifier system must not be modified from the design or safety engi­
neering point of view except with our express agreement. Any modification
shall exclude all liability on our part for any resultant damage.
In particular, any repair or soldering work on motherboards (replacement of
components, apart from EPROMs) is prohibited. When exchanging com­
plete modules, use only original parts from HBM.
The amplifier system and/or individual components are delivered from the
factory with a fixed hardware and software configuration. Changes can only
be made within the possibilities documented in the operating manuals.

tion switch (protection class I).
Use only the mains cable included with delivery, which is fitted with a ferrite
core.
The device must be switched off and the mains plug disconnected from the
socket before opening the device.
Never pull the mains plug out of its socket by the supply lead.
Do not operate the device if the mains lead is damaged.
If an amplifier channel is removed, the module must be sealed with a blind
panel.
Only operate built-in devices once they are installed in the housing pro­
vided.

MGCplus A0534-30.0 HBM: public 13

Electromagnetic compatibility

The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1); protection class I.
The insulation resistance of the connecting cables (v50V) must be at least
350V(AC).

1.1 Electromagnetic compatibility

The MGCplus device has been tested based on EMC product standard
EN 61326-1:2013. This standard includes definitions of limit values and test
levels for various electromagnetic environments.
Regarding emission (EME), requirements are included for class A (industrial
environments) and class B (residential, business and commercial environ­
ments as well as small businesses). Laboratory applications also usually
require class B.
The product standard here references to EN 55011:2009+A1:2010.
Regarding immunity to interference, the product standard includes require­
ments for controlled electro-magnetic environments (lowest requirements),
general environments and industrial environments (highest requirement).
MGCplus meet the following requirements:
- Emission (EME): Class B
- Immunity to interference: Industrial environment
The MGCplus series and the individual modules thus essentially meet the
highest requirements and are therefore suitable for use in all environments
described in the product standard.

 Introduction
System description

3.3 System description

The MGCplus system is structured modularly. Depending on the housing

variant, up to 16 slots are available for single and multi-channel amplifier
modules. Thus up to 128 measuring points can be measured in an
MGCplus.
Each amplifier module works independently through its own CPU. Data
preparation, for example taring, filtering and measuring range adjustment, is
carried out digitally. This eliminates the disadvantages of analog data prepa­
ration, such as time and temperature-dependent drift, errors due to compo­
nent tolerances, greatly limited flexibility and extensive circuitry. An essen­
tial precondition for this is analog/digital conversion with no loss of
information. The digitally conditioned signal is directed to the internal bus.
For single-channel modules, two analog outputs (voltage) are available in
addition to the digital measured values.
An internal standard PC computer in credit-card format collects data with a
total sampling rate of up to 307,200 measured values per second (4-byte
integer format: 3-byte measured value + 1-byte status). All measurement
signals can be acquired in parallel, since each channel has its own ADU. No
Sample & Hold or Multiplexer is used in the MGCplus. This ensures continu­
ous digital filtering and maximum signal stability.
Data is sent to an external computer or PLC via interfaces such as Ethernet.
A large part of the system functionality is implemented by device-internal
software (also called firmware). We therefore recommend you use our free
firmware updates and always keep your devices updated to the latest
firmware version. For further information go to www.hbm.com/downloads.

Installation of the CP52 communication processor

3.7 Installation of the CP52 communication processor

For type "D" housings (ER003D or TG001D, etc.) the existing communica­
tion processor (CP22/CP42) can be replaced by the CP52 communication
processor.
► Loosen the screws on the old communication processor, the blind panel
(only with CP22) and the cover of the NT030 power supply unit.
► Remove the parts.
► Insert the new CP52 communication processor and screw it in place.
► Fit the power supply cover of the NT030 and screw the cover in place.
The process is similar when subsequently installing a CP52 communication
processor in an MGCplus housing (type "D" or type "E") that was initially
configured without a communication processor.
► Loosen the screws on the blind panels, if there are any, of the SY03 syn­
chronization interface and the power supply cover.
► Remove the parts.
► Insert the new CP52 communication processor and screw it in place.
► Fit the power supply cover of the NT030 or NT040 and screw the cover
in place.

If the communication processor is installed subsequently in a system where

none was present before, the housing cover must also be removed to check
the setting of the CP switch (S3). It must be set to "yes" so the system can
be started with the communication processor. Then the housing cover can
be closed again.

CAUTION

S Protect the devices in a desktop housing from moisture and dampness

or weather conditions such as rain, snow, etc.
S Make sure that you do not cover the ventilation openings at the side, the
openings for the power pack fan on the back side of the device and the
openings underneath the device.
S Do not expose the device to direct sunlight.
S Comply with the maximum permissible ambient temperatures for the sys­
tem devices, as stated in the technical data sheet.
S For installation in 19" electrical enclosures, due to poorer heat dissipa­
tion, measures must be taken to ensure that the maximum permitted am­
bient temperature (refer to the technical data sheet) is not exceeded! We
recommend forced venting in any case and in especially critical cases
intermediate spaces between the upper and lower rack frames.
S The devices are classified in overvoltage category II, degree of pollution 2.
S Install the device so that it can be disconnected from the mains at any
time without difficulty.
S It is safe to operate the MGCplus up to an altitude of 2000 m.

CAUTION
The power supply fuse may only be replaced by the manufacturer's service
personnel!

Grounding switch
In the factory setting ( ), the grounding switch connects supply voltage
zero with the protective conductor. If external devices (transducer, com­
puter) have already set up this connection resulting in ground loops (hum-
pickups), the grounding switch must be opened ( ).

4.1.2 Synchronization of multiple CP52 devices

4.1.2.1 Synchronization of multiple CP52 devices via a

synchronization jack

Connected devices are automatically detected and synchronized when syn­

chronization jacks are occupied. Connect the master device with the first
slave device (Sync In, X1) via the output jack (Sync Out, X2). If there are
additional slave devices, connect the input jack (Sync In, X1) in turn with the
output jack (Sync Out, X2) of the previous slave device (Sync Out, X2).

put.

Green The device is in slave mode, correctly synchronized
and ready for operation.
Yellow The device is in slave mode but is not synchronized.

 Connection
Connecting the MGCplus in a tabletop housing/rack frame

If several MGCplus systems are to be synchronized with each other, each

system must be equipped with a CP52 communications processor. To syn­
chronize MGCplus systems with CP52, you need a synchronization cable
with the HBM part number 1-KAB2125-2 (2 m in length).

Fig. 4.1 Example of synchronizing two MGCplus systems equipped with CP52.

The overall length of the synchronization chain (total length of cable be­
tween the sync master and the last sync slave) must be less than 150 m. A
termination resistor should be used if the line length is >15 m. We recom­
mend that you attach a termination resistor connector to the Sync Out
socket (X2) of the last sync slave. This connector is available from HBM on
request. The maximum number of MGCplus units that can be synchronized
is 32.

Powering up the system

When connecting the system, the sync slaves must be connected first.
Connect the system that will work as the sync master last of all.

4.1.3 Synchronization of CP52 with CP22/CP42

The synchronization jack enables MGCplus systems with CP52 to be

synchronized with MGCplus systems with CP22/CP42.
To do this note the following points:
Both CP42 and CP52 can be the synchronization master. CP22 can only be
a synchronization slave.
Use the following cables for this:
1-KAB2126-2: CP52 (master) to CP22/CP42 (slave)
1-KAB2127-2: CP42 (master) to CP52 (slave)

The synchronization status for CP22/CP42 is indicated by a multicolor LED.

Shielding design

4.2 Shielding design

Sources of interference can cause electromagnetic fields which can induce

interference voltages inductively or capacitively via the connection cable
and device housing in the measuring circuit and therefore interfere with the
device function. It must be ensured that the devices used in the system also
do not transmit any electromagnetic interference. Electromagnetic compati­
bility (EMC), which encompasses both the required electromagnetic interfer­
ence immunity (EMI) and the permissible electromagnetic interference emis­
sions (EME), has become increasingly important over the years.

The HBM Greenline shielding design

The measurement chain is completely enclosed by a Faraday cage by
appropriate routing of the cable shield. The cable shield is extensively con­
nected with the transducer housing and is routed via the conductive plug to
the amplifier housing. The influence of electromagnetic interference is signif­
icantly reduced by these measures.

The conductive housing

ensures the connection
to the plug or device

The cable shield is connected with the
Signal-carrying
conductive housing via strain relief
contacts

36 A0534-30.0 HBM: public MGCplus

 Connection
Shielding design

Notice
All parts of the measurement chain (including all cable connection points
such as plugs and couplings) must be surrounded by a closed EMC-tested
shield. Shield junctions must represent a full contact, closed and low-imped­
ance connection. This is the case for original HBM plug connections.

Ground connection and grounding

As the signal ground and shielding are separated in EMC-compliant cabling,
the shielding can be connected at more than one point to the ground, i.e. via
the transducer (metal housing) and the amplifier (housing is connected to
the ground conductor).
If there are differences in potential in the measuring system, a potential
compensating line must be laid (recommended value: highly flexible
stranded wire, wire cross section 10mm2). Signal and data leads must be
set up so they are physically separated from current-carrying power lines.
Ideally, cable ducts made of sheet metal with an internal partition should be
used. Signal ground, ground and shielding must be laid out separated as
much possible.
In order to minimize the effect of electromagnetic interference and differ­
ences in potential, the signal ground and ground (or shielding) are designed
to be physically separate in the HBM devices. The ground connection or a
separate mains protective conductor should serve as the ground connec­
tion, as is the case for potential compensation in buildings, for example. The
ground cable should not be connected to a radiator body, water pipe or simi­
lar objects.

HBM recommends this connection technique for measuring amplifiers

ML10B, ML30B, ML38B, ML55B and ML455 with connection boards
AP01i, AP03i, AP14 and AP455i with very small measuring ranges, in
environments especially subject to interference and when long cables
are used.
This applies to all bridge connections.
With cable lengths >50 m, a resistor with half the value of the bridge
resistance (R_B/2) must be connected in each sense lead of the trans­
ducer.

AP815i can measure decentralized half bridge circuits for which the active
SGs are separated by a line.

1) With decentralized half bridge circuits the measured value must be acquired at both ends of the connecting line between the active SGs.
With standard half bridge circuits a connector can also be bridged.

Information
Information about AP418i connection boards:
When laying transducer cables outside of enclosed areas or with cable
lengths greater than 30 m between the connection board and transducer,
the sensor cables must be designed with an additional, separately grounded
shield to ensure overvoltage protection. This can be done for example by
laying the cable in a metallic pipe or using double-shielded cable, in which
case the outer shield must be connected to ground potential or protective
conductor potential where it is close to the connection board (for example
where it enters the switch cabinet). HBM recommends Triaxial cable for this
purpose.

ML74B communication card and the AP74 connection board. In combina­
tion with the NT030 power pack, you can connect a maximum of 12 modu­
les per board and a maximum of 25 modules per MGCplus device (a maxi­
mum of 256 channels per CP42 and 512 channels per CP52 in total). The
combination of NT040 with CP52 enables up to 50 modules per MGCplus
device to be connected. For further information regarding connection and

4.5.1 Inputs/outputs of the CP52

The CP52 communication processor has two digital inputs and outputs
each. The digital inputs and outputs must be operated with an external cur­
rent feed (12 V ... 24 V).

Inputs (0 V ... 24 V)
You can assign the following functions to the digital inputs:
S Start to record measured data with an external trigger
The status of the inputs and outputs can also be queried with the MGCplus
terminal commands.

Outputs (0 V ... 24 V)
The following functions are assigned to the digital outputs:
S Disk is full
If the remaining storage space of the USB mass storage medium in the
CP52 is 1 Mbyte, the output is set to logical High. The status can be
changed using the MGCplus terminal commands.
S System is up and running
Inputs and outputs When the initialization is completed and measured values are acquired, the
output is set to logical High.

Notice

Functions can only be assigned to the digital inputs and outputs of the CP52
communication processor by using the MGCplus Assistant software from
HBM.

4.5.2 Analog output on the front panel

On the front panel of a single-channel module there is a BNC socket for the
analog output signal VO1. (This socket is used for test purposes. Stationary
wiring should always be done with the connection boards, since there is no
noise voltage with this method).

Notice

Please note: The input resistance of the connected device must be greater
than 1MΩ.

When connecting a coaxial cable to the analog output of the ML60B ampli­
fier module, a ferrite (available from Würth, art. no. 742 711 72, or similar)
must be placed on the cable for operation in environments of limit value
class B in accordance with EN55011 and EN55022 (residential applications,
business and commercial applications as well as small businesses).

4.5.3 Connection boards AP01i/AP03i/AP14/AP17

In addition to the transducer connection, the connection boards also provide

several output and control signals, depending on the option selected.
They are explained in greater detail in the following sections.

S On pin 13 the analog output signal of VO1 is present (and also on the
BNC socket on the front panel).
The connected load resistance must be greater than 5 kohms.
The following signals can be assigned to outputs VO1 and VO2:
S S1: Gross
S S2: Net
S S3: Peak value 1
S S4: Peak value 2
S S5: various differential, integration and mean value
S On pins 17 to 20 the switching states of limit switches 1...4 are present.
The switching states are indicated by two different HCMOS voltage lev­
els:
Positive logic:
Level 0 V: limit switch OFF
Level 5 V: limit switch ON
S On pin 21 a level of 5 V (High level) is present, which can be used as a
warning signal. In case of a fault or broken transducer cable the output
signal is set to 0 V (Low). However, this signal is also set to zero during
the autocalibration cycle (every 5 minutes for about 1 s).

Remote controls
On pins 2 to 9 of socket 2, remote controls CTRL 1...8 are present for con­
trol of some amplifier functions. These contacts are active if they have been
enabled with the AB22A display and control unit, i.e. in REMOTE operating
mode. The assignment of these remote controls is freely selectable. The
possible functions are described in
section 8 Additional functions .

Information
In the factory settings the contacts are not assigned.

Termination resistors must be connected for long lines (>100m) and high
frequencies (>200kHz). To do this the 3x DIP switch S2 on the motherboard
of the AP17 must be switched to "ON".

Devices in the desktop housing and rack frame

5 Starting up
This section shows you the necessary operating steps to place your mea­
surement chain (measuring amplifier system and transducer) in operation.
This will enable you to perform a functional test of all the components. The
steps are deliberately described in very general terms so that there is no
need to go into the details of specific transducers or amplifier modules.
However the description can easily be applied to your measurement chain.
In some cases – especially when connecting transducers – reference is
made to the following sections. We also point out some typical errors that
may occur during start-up.
After the initial start-up is performed and the amplifier module is adapted to
your transducer, you will be ready to become familiar with the remaining
functions and possibilities of the MGCplus measuring amplifier system.
S Unpack the MGCplus.
S Check the MGCplus for damage.
S Is the delivery complete?
S Compare the contents of the package with the enclosed documentation
list. Is the documentation complete?

5.1 Devices in the desktop housing and rack frame

If you have not already received your measuring amplifier system complete,
note the following information as you put together your system:
S Plug in the measurement cards from the front and the corresponding
connection boards from the back.
The assignment is important in this process.
S If you are using the wide connection board or amplifiers (8 sub-units),
plug them into slots 1, 3, 5, etc. Slots 2, 4, 6, etc. on the front and back
must be left free or fitted with blind panels.

MGCplus A0534-30.0 HBM: public 99

Starting up
Devices in the desktop housing and rack frame

S For safety reasons all free slots (amplifiers or connection boards) must
be covered by blind panels.
S Check to make certain the amplifiers and connection boards are securely
plugged in.
S Connect the device to the mains with the mains cable provided.
S Connect your transducer to the applicable socket on the back of the
connection board (designation BU01). If you are using a cable pre-
assembled in-house, please note the pin assignments for your
transducer in section B.
Comply with the safety instructions on è page 11.

7.1 General information

This section describes the steps you will need to follow to perform a mea­
surement with MGCplus. At the beginning of each section an example ex­
plains the transducer-specific details for adapting the amplifier modules. Af­
ter you have adapted the amplifier modules you can start with the
measurements. Other functions such as limit switches and peak-value
memory are described in è section 8 "Additional functions", page 191 .

Steps to adjust the measurement chain

1. Transducer-specific settings Bridge type, bridge excitation voltage,
sensitivity, gage factor.
2. Settings for signal conditioning Zero balance, zero drift, tare value, filter
settings.
3. Display-specific settings; unit, decimal places, display range, step.
4. Settings of the analog output: Gross, Net, Peak value, Output
characteristics.
There are two ways to adjust the zero point and measurement range:
S By entering the given transducer characteristics
S By calibration with direct loading

You can use the cubic polynomial characteristic curve to correct the trans­
ducer signal (in mV/V). This adjusts the measured values to the true charac­
teristic curve. To do this enter the coefficients A0, A1, A2 and A3 of the third
order polynomial, which is described by the following equation:
YPh = A3@Yel3 + A2@Yel2 + A1@Yel + A0
YPh: Display in physical unit with polynomial characteristic curve
Yel: Measured value in electrical unit
The values of the coefficients can be found on the transducer calibration
certificate.
The amplifier itself requires coefficients (C0 ...C3) standardized to the value
1. The coefficients from the calibration certificate (A0 ...A3) are automati­
cally converted before they are forwarded to the amplifier (also in
MGCplus‐Assistant).

Butterworth t
The Butterworth characteristic shows a linear amplitude response with a

7.3.1 SG transducers

SG transducers (load cells and force transducer from HBM) are passive
transducers that have the following features:
S They must be supplied with an excitation voltage (carrier frequency or
direct voltage)
S They are SG full bridge circuits
S The transducer is identified by the following data:
- Maximum capacity (for example 20 kg)
- Nominal (rated) sensitivity (for example 2 mV/V)
These data items must be taken into consideration when adapting the
amplifier.
The standard setting for the excitation voltage UB with SG full bridge circuits
is 5 V. If higher measuring ranges are required or multiple transducers are
connected in parallel, a lower excitation voltage must be selected. The
individual values depend on which module is used.

Amplifier Measuring range limits (mV/V)

UB=10V UB=5V UB=2.5V UB=1V

ML38B - 0.2...5.1 0.4...10.2 -
ML55B - 0.1...3.06 0.2...6.12 0.5...15.3

With these measuring range limits, depending on the setting, a voltage of 1

7.3.2 Strain gages

The quantity used to assess material stresses is the mechanical stress to

which the material is exposed. One practicable method for experimentally
determining material stresses is based on strain gages (SG). A detailed de­
scription of SG technology can be found in the book "An Introduction to the
Technology of Measuring with Strain Gages" (author Karl Hoffmann, pub­
lished by HBM Darmstadt).

Measuring
Adapting to the transducer

The measurement system always measures the total strain () of the indi­
vidual SGs active in the Wheatstone bridge. Individual SGs are usually used
for mechanical stress analysis in practical applications.
The half bridge circuit and full bridge circuit are used on account of tempera­
ture compensation, the larger measurement signal, better cable resistance
compensation and for some stress states (measuring on a bending beam,
etc.). The most important characteristic value of a SG is the gage factor.
The MGCplus measurement system automatically switches to strain mea­
surements if a gage factor >0 is entered. The zero point and measuring
range are scaled in m/m. By changing the unit and the display value you
can derive other physical quantity quantities (such as mechanical stress in
N/mm2). If zero is entered as a gage factor, the system switches to mV/V.

7.3.3 Inductive transducers

Inductive transducers (for example force transducer from HBM) are passive
transducers that have the following features:
S They must be supplied with an excitation voltage (carrier frequency)
S They are inductive half or full bridge circuits
S The transducer is identified by the following data:
- Nominal (rated) displacement (for example 20 mm)
- Nominal (rated) sensitivity (for example 10 mV/V)
The standard setting for the excitation voltage UB with inductive transducers
is 2.5 V. If higher measuring ranges are required or multiple transducers are
connected in parallel, a lower excitation voltage must be selected. The indi­
vidual values depend on which module is used.

Amplifier Measuring range limits (mV/V)

UB=5 V UB=2.5 V UB=1 V
ML55B 1.5...45.9 3.0...91.8 7 .5...229.5

With these measuring range limits, depending on the setting, a voltage of

1 V ... 10 V can be generated on the analog output.

Important
The specified full scale values are maximum values that cannot be affected
by settings of the analog output!

7.3.4 Torque transducer

Torque transducers with different measurement principles require different

amplifier modules in the MGCplus system and therefore different operating
steps.
The HBM torque transducers in the type series TB1A and TB2 work with SG
full bridge circuits. The procedure described in è section 7.3.1
"SG transducers", page 135 must be followed to adapt the torque channel
(ML10B, ML30B, ML38B, ML55B) of these measurement shafts.
The adaptation of the speed channels (ML60B/ML460) corresponds to the
procedure described in this section.
The HBM torque flanges in type series T10… and T40… (without the -KF1
version) require connection board AP17 for operation with ML60B amplifier
modules (one amplifier module each for torque and rotational speed).
When using the amplifier modules ML460 (multi-channel module) with
AP640i connection boards, the T10 and T40 transducers must be powered
externally.
For calculating additional parameters, such as the rotation output (product
of torque and rotational speed), the freely programmable module ML70B is
recommended for MGCplus. Another option is to use "online calculation
channels" in the HBM catman data acquisition software.

7.3.7 Thermocouples

Thermocouples are active transducers. To perform measurements with ther­

mocouples you will need the ML801B amplifier module as well as connec­
tion board AP809. The temperature cold junction is built into the AP809. The
amplifier module performs cold-spot compensation and linearization for the
thermocouple type K.
If you selected 'Thermocouples' as the operating mode and °C or °F as the
unit, the corresponding temperature display will be in the selected unit. If
you select operating mode "75 mV", you will have the output voltage of
the thermocouple directly (without linearization and cold-spot
compensation).

7.3.9 Resistance temperature sensors

Resistance temperature sensors are passive transducers. For this trans­

ducer you will need the ML801B multi-channel module with connection
board AP835. It performs linearization automatically and indicates the cor­
rect temperature.
If you selected 'Resistance temperature sensor' as the operating mode and
°C or °F as the unit, the corresponding temperature display will be in de­
grees of the selected unit. If you choose volts as the unit, the output voltage
will be scaled accordingly1).
The settings are explained with the following example:
Resistance temperature sensors type Pt100; the temperature will be dis­
played in °C with a temperature of 50 °C equivalent to an output signal of
0 V. At 70 °C the output signal will be +10 V.

1) The permitted ranges depend on the bridge excitation voltage. If you set a measuring range that lies outside of of the adjustment range of
the amplifier, the maximum or minimum value will be applied.

7.3.11 Pulse counting

To count pulses you will need the ML60B or ML460 amplifier. This amplifier
is able to process a maximum pulse string frequency of 1 MHz. Further in­
formation about possible settings of this amplifier can be found in è section
7.3.4 "Torque transducer", page 158.
Incremental transmitters (used for example to measure angles) return two
square wave signals which are phase-shifted by 90. The duty ratio between
the High and Low of the two signals must be about 1:1.
The settings are explained with the following example:
An angle of rotation transmitter returns two signals, each with 180 pulses/
revolution. They will be realized in the display as 360. Due to the pulse
number per revolution, a value of 1 is specified as the step, since a higher
revolution is not practical. The level of the square wave signal is 10 V.
In addition to the measured value, a frequency signal with four times the
count pulses is required at the output.

Current-fed piezoelectric transducer

7.4 Current-fed piezoelectric transducer

Piezoelectric transducers with a built-in preamplifier are often used for ac­
celeration and force measurements. These transducers require a constant
current for supply. The measurement signal corresponds to the modulated
voltage on the power line. The DeltaTronT acceleration transducer from
Brüel&Kjaer is a typical representative of this product family.
To operate current-fed piezoelectric transducers you will need the AP418i
connection board and the ML810B amplifier. You can select coarse and fine
adjustment for the measuring range. 3 input ranges are available for coarse
adjustment: "0.05 V; "0.5 V; "5 V.
Example: If the required measuring range is 4 V, the next larger input range
"5 V is set.
The zero point defines the 0 V voltage generated at the output of the ampli­
fier. The nominal (rated) value is always defined relative to the zero point.
The settings are explained with the following example:
A DeltaTronT transducer will be used to measure an acceleration of up to
300m/s 2. The nominal (rated) value of the transducer is 1mV/ m/s2.
Measuring range (fine adjustment) 300 m/s2 x 1 mV/m/s2 = 0.3 V
Input range (coarse adjustment): "0.5 V ( > 0.3 V)

Measuring
Potentiometric transducers

7.6 Potentiometric transducers

Potentiometric transducers are passive transducers that must be supplied

with an excitation voltage. To work with a potentiometric transducer you will
need the ML10B amplifier with AP01i or AP03i, or ML801B with 6i. Please
note that the maximum resistance value is 5 kΩ.
The settings are explained with the following example:
The measurement will be performed with a potentiometric displacement
transducer with a nominal (rated) displacement of 10mm. The entire nomi­
nal (rated) displacement will be used. The display range is 10 mm.
The dependency of the excitation voltage and nominal (rated) input voltage
(mV/V) results in the following correlation for the measuring range to be set
with an excitation voltage of 2.5 V:

Nominal (rated) value to be set = Nom. (rated) voltage (displacement)

(RANGE) Excitation voltage
Nominal (rated) value (range) = 2.5 V/2.5 V = 1.000 mV/V
This value of 1000 mV/V or 1 V/V only changes if a potentiometric trans­
ducer is used with a partial range.
In the second method, a partial range calibration is performed with gage
blocks of 7 mm for calibrating the zero point and measuring range.

Limit values (single-channel modules only)

8.2 Limit values (single-channel modules only)

To assess dimensional or weight tolerances, or when monitoring forces,

pressures etc., it is often necessary to comply with specific setpoint or limit
values. Four limit switches are available for this in each amplifier module
(they are turned off in the factory settings).
You can assign the level, hysteresis and its direction for limit value
monitoring. The hysteresis value prevents the limit switch from "flickering"
when the switching threshold is reached.
The respective switching status is indicated by an LED on the front panel of
the amplifier module if the STATUS display mode has been enabled.
Display of
limit value Note the following point when working with limit values:
states
S The measurement signal must be present for at least 1ms. The
measuring voltage returned by the amplifier is compared internally with
the reference voltage. If the measuring voltage reaches or exceeds the
set reference voltage, the relevant logic output switches and the
corresponding LED indicates the switching status.

. . . Recording format
Reading a recorded file
To be able to read and interpret the data in the file, you must be familiar with
the internal format of the file. The data is recorded in a binary file structured
as follows:
The following header data items come before the actual data area:
S File ID (4‐byte LONG) // currently = 6001
S Number of channels (4‐byte LONG)
S Length of a data line (i.e. one measured value for all channels/signals) in
bytes (4‐byte LONG)
S Number of data lines (i.e. measured values/channel) in the file (4‐byte
LONG)
S The data format used to save measured values (4‐byte LONG)
S Sampling rate used to acquire measured values (4‐byte LONG)
S Size of the header area in bytes (4‐byte LONG) // currently = 512
S Reserved (4‐byte LONG)

Then the following items for each channel:

S Channel number (4‐byte LONG)
S Scaling information: Measuring range MR (4‐byte FLOAT)
S Scaling information: Offset (zero offset) OS (4‐byte FLOAT)
S Unit (4‐byte CHARACTER)
S Signal mask (4‐byte LONG)

The signal mask indicates how many values will appear in the data line per
channel:
S Bit 0 set: GROSS signal
S Bit 1 set: NET signal
S Bit 2 set: Peak value 1
S Bit 3 set: Peak value 2
This means that a maximum of 4 consecutive values can be displayed for
each individual channel.

262 A0534-30.0 HBM: public MGCplus

 System
Recording series of tests

This channel block is followed by information about the date and time:
S TimeDate (30‐byte CHARACTER)
The bytes that follow to the end of the header are reserved for future use
and may be left out. They are followed by the values, data line for data line
(the example shown here is based on bit 0 (Gross) and bit 2 (peak value 1)
being set):
S C1, 1 (Gross) C1: Channel 1
S C1, 1 (PV1)
S C2, 1 (Gross)
S C2, 1 (PV 1)
__________________________

New data line

S C1, 2 (Gross)
S C1, 2 (PV 1)
S C2, 2 (Gross)
S C2, 2 (PV 1)

Each value (measured value) takes up 4 bytes (data formats 1253=LONG

and 1257=FLOAT) or 2 bytes (data format 1255=INT). Integer formats are
saved in INTEL (TM) format, i.e. MSB -> LSB.
Depending on the data format used for data acquisition, the raw values
must be scaled for each channel:
S 1253 (LONG): Physical value = (binary raw value) / (256*7680000) * MR +
OS
S 1255 (INT): Physical value = (binary raw value) * 256 / 7680000) * MR + OS
S 1257 (FLOAT): Physical value = (binary raw value)
S MR: Measuring range
S OS: Offset

Information
The 1253 LONG format contains status information in the least significant
byte. To access this status, you should check this byte first (!) Scale, since
this will cause the least significant byte to be lost due to division by 256.

The status byte is structured as follows:

S Bit 0: Limit value output 1 active if set
S Bit 1: Limit value output 2 active if set
S Bit 2: Limit value output 3 active if set
S Bit 3: Limit value output 4 active if set
S Bit 4: Overflow of Gross signal if set
S Bit 5: Overflow of Net signal if set
S Bit 6: Calibration counter error if set
S Bit 7: Amplifier settings that are changed during the measurement (for
example by remote control) if they are set

10.3.2 Format of the MGCplus measurement files

When measurements are recorded on a storage medium, files with the

extensions *.mea, *.me1 and *.me2 are created. All the channels recorded
at sampling rate no. 1 are stored in the file with the extension mea, those at
measuring rate no. 2 in the file with the extension me1 and those at
sampling rate no. 3 in the file with the extension me2.
If the "Compression factor" option is also activated, additional files will be
formed with the extensions "sto", "st1" and "st2", containing an extract of the
minimum and maximum sample block values.
When measured values are recorded in files with the extensions mea, me1
and me2, the following options have to be considered:
S Time channel yes/no

If yes, the format of the time channel

MGCplus Device Time
S NTP time format
S IRIG time format

Measured value format

S 4-byte INT (LSB ... MSB)
S 2-byte INT (LSB ... MSB)
S 4-byte Float (LSB ... MSB)

10.3.2.1 Measured values

The measured values of each MGCplus channel are transmitted with 4

bytes: The Least Significant Byte contains the measurement status, the
other three bytes contain the measured value. The following table shows the
format of the measured values at the internal data interface of the MGCplus
system.

INT format) the status is checked to see whether it is s>15. If it

is, the corresponding measured value is replaced by a number
defined by the user.

If measured values are stored in an MGCplus measurement file in a

different format than 4-byte INT, information about the measurement status
is irrevocably lost. So we recommend that the 4-byte format is always used
when saving.
An example of how 32-bit INT values in the status and the physically scaled
measured value can be converted, is given below. In this example, the
variable z is one such 32-bit value.
z Ů NJ–2.147.483.647, . .. , 2.147.483.648Nj
The status s is obtained by carrying out the following mathematical
operations.

s + z–2 8 @ Ȳ2z ȴ1)

8

Obviously, it would be far more efficient to perform this operation in a

programming language such as C++ or Visual Basic, with the aid of
bitshifting operators (SHR, SHL).
The physically correctly scaled measured value can be calculated by
applying the following operation:
z @ c scale
y+ –c
(2 8 @ 7.680.000) offset
cscale and coffset represent the scaling information which is contained in the
relevant amplifier and also in the measurement files on the PC card hard
disk.

10.3.2.2 Time channels

The "MGCplus Device Time" time channel (called the "HBM" time channel in
the AB22A) is used to count 76.8 kHz periods. 46 bits are available for the
time count, so it will take 29 years for the counter to overflow.

t tot + 2 46 s + 916.259.689, 8133 s + 10.604, 86 d [ 29.05 a

The table below shows the "MGCplus Device Time" format.

Counter 1 Counter 2

8-bit status 23-bit counter + 1 bit sign 8-bit status 23-bit counter + 1 bit sign
Bit no.
0 7 8 3 0 7 8
1

In this format the time begins to be counted after the MGCplus system starts
up with t=0.
The format of the NTP time is an absolute format that contains the system
time of the communication processor. The time information is split between
2 counters of 32 bits each, with one counter containing the number of
seconds since January 1, 1970 00:00:00 UTC and the second counter
counting the s in the current second.
After February 7, 2106 (that is in about 100 years) there will be problems
with the NPT time.

IRIG time channel

This time channel is only available in conjunction with an ML01B on which
special firmware is installed (ML0135BP535.F72). This module is
synchronized to an external IRIG-B source and makes the time information
available in the system. The format of this time channel is identical to NTP
format (see below) with the only difference being that the second
component only contains the seconds of the current year that have passed.
So the channel always overflows with every new year!

10.4.1 Port usage

Certain Ethernet ports must be shared for communication between PC and

CP.
The following TCP ports must be shared for CP52:
- Port 7 for communication with the device
- Port 80 for the web server and firmware updates
The following UDP ports must also be shared to be able to find CP52 with
the HBM Device Manager or change interface settings:
- Port 31,416 to find CP52
- Port 31,417 to change interface settings using the HBM Device
Manager
The following TCP ports must be shared for CP22/42:
- Port 7 for communication with the device
- Port 80 for the web server (CP42 only)

10.4.2 Communication processor and multi-client mode

When a communication processor is delivered from the factory, it is only

possible to connect one PC to the MGCplus system. If you want to connect
several PCs to the MGCplus system the "Multi-client" option must be
activated. This is done with the "MGCplus Assistant" software, in the CP
Options dialog box. All interfaces support the multi-client capability of the
communication processor. The multi-client option also supports Ethernet
access via routers.
In total, up to 5 external clients can access the MGCplus. Only one client
can be linked to each interface. It is only possible to connect several clients
simultaneously via Ethernet (using an Ethernet switch with patch cables, for
example).
In addition to the external clients, there are also other internal clients (for
example ML70B, ML71B, and ML78), which are always active, regardless of
whether the multi-client option has been activated. So it is always possible
to record measurement data on a PC card and acquire data on a PC in
parallel.

MGCplus A0534-30.0 HBM: public 279

System
Interface

If two or more PCs are to be used with an MGCplus it is essential for

"MultiClient" to be activated.
While the measured values of one client are being recorded, none of the
other clients can make changes to the recording of measured data. External
clients can only reset the time channel. All the other measured data
recording parameters, such as sampling rate groups, triggers, channel
selection, etc., are divided between the client processes.

Notice
But every client can effect changes in the parameterization of every
amplifier. For example, should a client change the zero offset or the filter
setting of an amplifier, this will immediately have repercussions for the
recorded data of another client process. In this case, the recorded
measurement traceability information will not match the effective amplifier
parameters.

What constraints are there to consider?

The number of measured values that can be generated in an MGCplus is
limited to 307,200 per second (16 modules at a maximum of 19,200
measured values per second).
Each module in the MGCplus system can transmit no more than 19,200
measured values per second to the external interfaces. If one client request
net values, for example, and another gross values, this may cause "link
resource conflicts", which can be cleared by HBM software. Other
manufacturers' software can perhaps not resolve these "link resource
conflicts" automatically.
The communication processor has an internal ring buffer where measured
values can be stored temporarily if external users delay collection. In
multi-client mode, the various external clients must share this internal buffer.
HBM catman software (catman Easy/AP and catman enterprise) can be
used to view utilization of the buffer and data acquisition performance.
It is not possible to specify absolute rates for measured value transmission
over the individual system interfaces, as external influences (PC and
software performance) must be taken into account.
