• MP85A
• MP85ADP
• MP85A-S
• MP85ADP-S
The designation MP85A process controller will be used for all devices in this
manual. If text/data refers only to specific devices, this will be clearly indicated
in the text and one of the above designations used.
• Use shielded, low-capacitance HBM cables only.
Intended use
The MP85A process controller 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 application concerned during use. The same applies to the use of accessories.
Each time, before commissioning the device, 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 must establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling,
limit value switches, etc.
The MP85A process controller must not be connected directly to the
mains. The supply voltage must be 18 − 30 V.
General dangers of failing to follow the safety instructions
The MP85A process controller corresponds to the state of the art and is
failsafe. 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 Manual
and in particular the technical safety instructions.

Protect the device from direct contact with water (IP20).
Maintenance and cleaning
The MP85A process controller is maintenance-free. Please note the following
points when cleaning the housing:
− Before cleaning, disconnect the device from the power supply.
− Clean the housing with a soft, slightly damp (not wet!) cloth. You should
never use solvent, since this could damage the labeling on the front panel
and the display.
− When cleaning, ensure that no liquid gets into the device or connections.
Residual risks
The scope of supply and performance of the MP85A process controller 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 remaining dangers.
Prevailing regulations must be complied with at all times. There must be reference to the remaining dangers connected with measurement technology. After
making settings and carrying out activities that are password-protected, you
must make sure that any controls that may be connected remain in safe
condition until the switching performance of the measurement system has
been tested.
Any risk of remaining dangers when working with the MP85A.process
controller is pointed out in these instructions by means of the following

The control inputs are available at screw terminals 3 and 4 and are electric-
ally isolated from the internal supply voltage and from the control outputs.
• at screw terminal 3: control input 1
• at screw terminal 4: Control inputs 2...5 (MP85A/MP85A-S only)
An external reference potential (
IN ), to which the control input signals relate,
must be connected for the control inputs.
The MP85A process controller digital inputs are flank controlled by
transition from 0V to control voltage (e. g. 24V). The set digital input
function is only implemented once with the rising flank. The subsequent
permanent application of the control voltage does not cause a further
action.

3.4 Transducer
Two transducers can be connected to screw terminals 5 and 6, independently
of one another. The two measurement channels are parameterized using the
PME Assistant (menu: Transducer).
3.4.1 Synchronization of carrier frequencies
Synchronization prevents interferences occurring due to small differences in
the carrier frequencies of the individual amplifiers, i.e that amplifiers disturb
each other.
Synchronization is advisable for transducers with carrier frequency excitation
when
D the transducer cables of several devices run side by side
D the measuring points are unshielded and are close together
Even if devices work without a CAN bus, the flat ribbon cable should always
be used for synchronization between them, see Section 2.2 on Page 14.
WARNING
To synchronize several devices, declare one device as master and set all
other devices as slaves. Setting is implemented via the PME Assistant
program (menu: Basic settings −> Hardware synchronization).

Fig. 3.4: Connecting different transducers in “carrier-frequency amplifier” mode
When connecting a transducer in four-wire configuration, the sense lines must
be connected to the appropriate bridge excitation circuit (Pin 3 with Pin 2 and
Pin 5 with Pin 4). With cable lengths >50 m, a resistor with half the value of
the bridge resistance (RB/2) must be connected instead in each sense lead of
the transducer.

NOTE
Use standard HBM cables or other shielded, low-capacitance measurement cables for connecting the transducers. Connect the shield of each
transducer cable via as short a line as possible (t5 cm) and a flat
connector (4.8 mm; “Faston”) on the right next to screw terminal 6.
Otherwise EMC protection is not ensured.
CAUTION
Line break detection
MP85A process controllers have line break detection for the connected transducers.
The excitation voltage lines and the measurement signal leads are monitored.
With sense leads, a wire break is only reported as a fault if both lines are
broken; with measurement signal leads and excitation voltage leads, the
break of a single line is also reported as a fault. When a single wire breaks in
a sense lead, the measured value displayed is too high.
This also means that if the connection is faulty (for example, when full bridges
or half bridges are connected in four-wire configuration and the feedback
bridges are missing) an error message appears (display: Transducer error).

A supply voltage is available at screw terminals 5 and 6, pins 7 and 8 for
feeding incremental encoders, transducers with an SSI interface and sensors
with voltage signal.
An internal or external power supply can be selected via switch S1. The
device must be open to do this (see Chapter 4).
• Transducer supplied from MP85A process controller:
Transducer supply voltage 5 V "10%, 150 mA max. (for both channels
together). The power supply is then not electrically isolated from the meas-
urement system.
• Transducer supplied from an external power pack:
At screw terminal 3, pins 5 and 6, a voltage of between 10 … 30V
DC
(nominally 24VDC), is supplied, including ground. A current of max. 300 mA
(for both channels together) can then be drawn at screw terminals 5 and 6,
pins 7 and 8.
This external supply voltage is electrically isolated from the measurement
ground and simultaneously feeds the digital control outputs.

CAUTION
The differential signal of the measurement signal and the zero index signal must each be minimum 1.2 V.
The voltage to measurement ground must not exceed 14 V in any line. If
necessary, the voltage must be reduced via a voltage divider.
3.4.4 Piezoelectric measurement chains
The inline charge amplifier model CMA or CMD is required for operating
piezoelectric sensors on the MP85A process controller. The charge amplifier
is supplied externally with 24 VDC and is available from Pin 7 and 8 of the
screw terminals 5 and 6 of the MP85A process controller (see Chapter 3.4.3,
Active sensors, Fig. 3.7).
Internal or external voltage in the MP85A process controller can be selected
via switch S1. The device must be opened to do this (see Chapter 4) and the
switch S1 set to “24V external”.

carried out before starting a measurement (Pin 3) MEASURE / RESET. With
an input voltage of 0 V at PIN 3, the charge amplifier is in the measurement

mode MEASURE. If a voltage of 24 V is present at PIN 3, the charge amplifier
switches to RESET.
TIP:
The reset signal can be generated externally or via the MP85A process
controller. To do this, the process signal “Reset piezo sensor” must be set to a
digital output of the MP85A process controller (PME Assistant, menu: Digital
outputs, circuit logic: positive).
TEDS:
The charge amplifiers have TEDS functionality for the voltage input which is
available in MP85A process controller from hardware version V1.07. When
operating without TEDS, the measurement ground (charge amplifier, Pin 6)
must be connected directly to Pin 3 of the MP85A process controller. The
yellow cable (TEDS) is therefore not required.
The charge amplifier has a measuring range selection RANGE1 / RANGE2.
Selection is via Pin 2 of the charge amplifier. The switching signal can be
supplied by an external control or the digital inputs of the MP85A process
controller. If a voltage of 0 V is present at Pin 2, measuring range 1 (100%
F
) is active at the charge amplifier.
nom
TIP:
The CMA charge amplifier gives you the option to zoom into a second measuring range (20% of the nominal (rated) force = 100% output span). A voltage
of 24 V
must be applied at PIN 2 for this.
DC
The changed measuring range must also be set in the MP85A process
controller, either automatically via the TEDS function or using the scaling
option of the input channel.

CAUTION
After RESET, the charge amplifier output is set to zero, but this does not
mean that the machine generating the force is force-free. Make sure that
the force transducer is not overloaded, even though the output signal is
still in the −10 − +10 V range.
Once all the force is removed, a negative voltage signal is present with
the value of the voltage output for a RESET, without having to RESET
again.

3.5 TEDS-transducers (electronic data sheet)
3.5.1 TEDS connection
TEDS stands for “Transducer Electronic Data Sheet”. Transducers with electronic data sheets as per standard IEEE 1451.4 can be connected to the
MP85A process controller. This enables the automatic setting of the measuring amplifier: The transducer characteristics (electronic data sheet) are read
and translated into own settings and measurement can then start. A six-wire
configuration must be used for TEDS to be connected.
Fig. 3.10: MP85A process controller with TEDS technology
3.5.2 Parameterization with TEDS
If a transducer with TEDS, containing the parameterization data for a sensor,
is connected, this can be used to parameterize the MP85A process controller
automatically.
When the MP85A process controller is activated, it automatically detects
whether a TEDS is connected. When the transducer is replaced in the activated state, the new TEDS is also detected automatically.
To monitor TEDS functionality and to protect scaling from manual intervention, check the boxes in the TEDS dialog box in the PME Assistant
(menu: TEDS). TEDS functions can be enabled individually for each
channel. Using TEDS for piezoelectric measurement chains is described
in Section 3.4.4 .
NOTE
A2392−5.0 en HBM
Page 28
28
Set up with the PME Assistant
In the PME Assistant, choose the desired conversion unit from the selection
menu in the “TRANSDUCER” area. If instead you want to use the unit stored
in the TEDS directly, deactivate this function in the TEDS dialog box.
When the TEDS is activated, its scaling data will be read out and converted to
the required physical unit. Should the unit stored in the TEDS and the
required conversion unit be incompatible because they describe different
quantities (e.g. torque transducer connected, conversion unit is “N”), an error
message is generated and scaling does not take place.
If a scaling error is reported once the TEDS is activated, the reason may be
that the value range specified by the two characteristic curve points is so
great or so small, that the measured values cannot be displayed with the set
decimal places.
You then need to adapt the number of decimal places in the “Amplifier” area. It
may possibly help to change to a different power of ten, such as “N” to “kN”.
MP85A process controller
The PME Assistant displays this information for each channel in the “TEDS”
area with the “TEDS error status”. For an accurate analysis, it is advisable to
display the data stored in the TEDS. You need the TEDS Editor and suitable
hardware, e.g. the HBM TEDSdongle, to connect the sensors.
The data for the minimum and maximum bridge excitation voltage in the
TEDS is also checked.
If, instead of using the PME Assistant, you are parameterizing directly e.g. by
bus command, you must use Object 2122 to set the required conversion unit
before activating TEDS.
The available units match the selection list provided by the PME Assistant.
CAUTION
If several transducers are connected to an MP85A amplifier input in
parallel, their TEDS data cannot not be used as neither the error-free
reading out of parallel connected TEDS is ensured nor can a summation
of the individual parameters take place. In this case, ensure that the
fields in the TEDS dialog are not activated for the channels concerned.
3.6 Interfaces
Use the PME Assistant to set up and parameterize the device via the Ethernet
or CAN interfaces. In automatic applications, the devices are integrated into
the machine control via fieldbus interfaces.
A2392−5.0 enHBM

3.6.1 Ethernet interface
An RJ45 socket for Ethernet connection is located underneath the MP85A
process controller as standard.
RJ45
29
Fig. 3.11: Ethernet connection
The device can also be integrated into an existing Ethernet network. It
supports speeds of 10 Mbit/s and 100 Mbit/s. The transmission speed is automatically adapted to the existing network. Category 5 or higher cables must
be used for this. This enables line lengths of 100 m to be implemented.
Fig. 3.12: Integrating the MP85A process controller into an existing Ethernet
network
Notes on operation in an Ethernet network
In order to avoid network problems, you should check the following points
before connection to an Ethernet network:
• Are the connected device addresses unique, i.e. no identical IP addresses?
A2392−5.0 en HBM
Page 30
30
MP85A process controller
• Does the network have sufficient reserves for the transmission of the
planned data or could the network load become too great?
• Are there nodes that could load the network through broadcasts, i.e. data
sent to all nodes?
In order to avoid disturbance of measurement operation by other network
nodes, you can also operate the devices in a separate network disconnected
from your company network. Connection to the company network would only
be necessary if external access to the measurement devices themselves is
necessary. If access to the generated data alone is required, you can implemented this with a PC connected between the networks − linked via one
network card to the devices and via a second network card to the company
network.
If the device is to be connected to the company network, we recommend the
use of a “Managed Switch” as these (higher quality) devices are by experience less susceptible to disturbances. The network with the measuring instruments and any PCs integrated in this network is then connected to the
company network via the Switch.
In order to achieve the best possible separation between the network with the
measuring instruments and the remaining company network, you can also use
a router that separates both networks and only transmits messages between
the two networks when necessary.
3.6.2 CAN interface
The CAN bus is connected via screw terminal 1. A maximum of 32 CAN
nodes can be connected in one bus segment (in accordance with the
CANopen specification).
The CAN bus needs a termination resistor of 120 Ω
node
. The maximum number of termination resistors the bus cable can have
on the first and last bus
is two. The MP85A process controller has an integrated termination resistor,
which is activated by toggle switch S2.

If the first or last device in the bus cable is not a PME device, a 120 W re-
sistor must be connected to each of these external devices.
The baudrate of all devices must be identical to that of the CAN master.
The baudrate must be reduced for greater line lengths according to the
CAN specifications.

5 Starting up/Setting up mode
To prepare the MP85A process controller for a measurement task, the
following requirements must be met and the relevant steps taken:
• You require an MP85A process controller and either the PME Assistant or
INDUSTRYmonitor program.
• The hardware must be set up: Transducer, MP85A process controller, PC
with software (from Section 5.2).
• The software must be installed (from Section 5.3)
To connect the MP85A process controller to a PC, you need:
− for Ethernet operation (Section 5.2.2 ):
• Ethernet crossover cable
− for CAN interface operation:
• CAN adapter (Section 5.2.3 ), either PCAN USB-to-CAN or PCAN card
(PCI or ISA)
The MP98A process controller must be connected to a PC via the Ethernet
cable or the CAN adapter. Once you have launched the software, you can set
up the MP85A process controller with the PME Assistant (Section 5.4).
In order not to invalidate subsequent statistics while in set up mode, the PME
Assistant (menu: Data storage) can be used to temporarily switch off the statistics processing.
TIP:
Detailed instructions are included in the PME Assistant Online Help. To call
the Help, the PME Assistant must be installed. For a quick guide to operating
the measurement system, refer to the FASTpress Suite quick start guide.

press the SET key. This will close all the files and write the
FAT.
The display briefly shows the message “MMC/SD Disk Closed” or,
in the case of error, “MMC DiskClose Err”. The MMC/SD card then
switches to the “Stopped” status and can be removed from the device. If there is no more space left on the memory card, it automatically switches to the “Stopped” status. This status can only be left
when the memory card is removed from the device. Re-initialization then follows automatically.
6. Kinds of error
During measurement, the ! character in the status field (in measuring mode)
indicates an MP85A process controller error.

NOTE
The possible error messages are summarized in Chapter 10, “Error messages”.
7. Firmware update (F-Update)
To update the firmware, use the program PME Update. A description of the
procedure can be found in the online help. The program can be used to
transfer a new firmware version to several devices simultaneously. In order
not to conflict with the processing of a process (no measurements or evaluations can be implemented during an update), you can specific from firmware
version 2.22 or higher that the firmware update is only implemented on the
device following manual confirmation (F-Update: Permitted!). If confirmation
does not occur within 15 minutes, no changes are made to the firmware.
The firmware update program is available on the System CD or can be downloaded from the HBM website.
We recommend saving the device settings (device backup) before any
updates.
8. Device backup
All MP85A process controller settings can be saved to MMC/SD card via the
integrated keyboard and then, e.g. transferred to another MP85A process
controller.
Using the device menu, all 31 Flash parameter sets, including all interface
settings of the MP85A process controller, can be saved to the memory card
A2392−5.0 en HBM
Page 42
42
MP85A process controller
as a backup (“S-Status Save”) and reloaded into the MP85A process
controller where necessary. When loading, you can select whether loading
should take place without interface parameters (“S-Status Restore”) or with
interface parameters (“S-Status Load-Com”), see Chapter 5.1.3. Confirm the
action by pressing the SET button. Progress is displayed as a % display in the
device display.
CAUTION
No measurements or evaluations are implemented during a device
backup and the response times of the device to the software or controllers take longer!

MP85A process controller
NOTE
If ! appears on the display or the status LED glows red, an error has occurred. Please refer to Chapter 10 “Error messages”.
• Connecting the bus system
To find out how to connect several devices to a bus, refer to Sections 2.2
(Page 14) and 3.6 (Page 28). Note that devices must be synchronized for
error-free operation.
5.2.2 Establishing the Ethernet connection
For an MP85A process controller to communicate with the PC, the device
must be connected to the PC. Use an Ethernet crossover cable (1-KAB239-2)
for direct connection. The connection (RJ45 socket) is located underneath the
MP85A process controller. When operating several devices in an Ethernet
network, we recommend the use of industrial Ethernet switches.
RJ45
As a minimum, category 5 cables with a maximum line length of 100 meters
are used for this.
Further information on connection setup and interface settings can be
found in the operating manual “CAN/PROFIBUS/Ethernet MP85ADP
FASTpress interface descriptions”.

5.4.1 Using the Ethernet interface
Launch the PME Assistant program and enter the required interface connection in the Start window:
• In the Interface field, select “TCP/IP”. The PME Assistant now gives you
the option of using the preset IP address or setting a new one.
• The address cannot be assigned automatically via DHCP. So you must
make sure that the IP address of the MP85A process controller differs
from the address of the network being used in max. one segment.
A2392−5.0 enHBM
Page 49
MP85A process controller

• In the subnet mask, a zero must be set in this position. All other
segments in the subnet mask must be set to 255.
• Now use the “Add IP to device list” button to transfer the IP address of
the MP85A process controller to the device list.
Alternatively, you can also press the “Scan” button to run a bus scan. In
this case, all the devices found will be displayed in the device list.
• If several MP85A process controllers are connected to the Ethernet
network via a switch, for example, make sure that each address has only
been used once. If you do not know the settings, you can query them via
the MP85A process controller keyboard (see Chapter 5.1.2).
• Use the “Start” button to launch the PME Assistant. The MP85A process
controller automatically sets the transmission speed to 10 Mbit or 100
Mbit.
5.4.2 Using the USB interface
Launch the PME Assistant program and take the following steps to configure
the USB interface:
• In the Interface field, select “CAN”. The PME Assistant now gives you the
option of selecting the CAN network to be used.
• The baudrate in the CAN network must be the same. In the delivery
condition, the baudrate of the MP85A process controller is set to 1 MBit/s.
• If you select “Use as standard”, this network will be chosen automatically
the next time the system starts up.
• If several MP85A process controllers are connected to the CAN network,
make sure that each address has only been used once. If you do not
know the settings, you can query them via the MP85A process controller
keyboard (see Chapter 5.1.2).
• Click the “Scan” button. The PME Assistant now searches for devices
connected to the CAN network and includes them in the device list.
• Use the “Start” button to launch the PME Assistant.

5.5 Automatic version recognition
MP85A process controller
If MP85A process
controllers are recognized
that use a firmware not fully
supported by your version
of the PME Assistant, the
following message appears:
The firmware of the device can be determined via the display of the MP85A,
PME Assistant or the INDUSTRYmonitor program.
The latest PME Assistant is always compatible with all MP85A(DP)-(S)
devices.
The latest software and firmware versions can be found on the HBM website:
www.hbm.com −> Support −> Software-/Firmware-Downloads.
NOTE
5.6 Firmware update
The firmware update program is installed using the supplied system CD. The
latest program and firmware versions can also be found on the HBM website:
www.hbm.com −> Support −> Software-/Firmware-Downloads.
New functions are often implemented via firmware and can then be loaded
into existing devices.
A2392−5.0 enHBM
Page 51
MP85A process controller
NOTE
The device settings remain unchanged if the firmware is updated. However,
we recommend that all settings be saved via the PME Assistant to the PC
before an update.
51
Simultaneous update of several devices can be selected.
In order not to conflict with the processing of a process (no measurements or
evaluations can be implemented during an update), you can specific from
firmware version 2.22 or higher that the firmware update is only implemented
on the device following manual confirmation (F-Update: Permitted!). If
confirmation does not occur within 15 minutes, no changes are made to the
firmware.
5.7 Offline operation
In offline operation, the PME Assistant can be used without a connected
MP85A process controller to create a device setting (parameter set) and save
it in XML format to PC. The device setting can later be transferred to the
MP85A process controller.
The offline mode is started as follows:
− Open the PME Assistant and select the “Offline” interface.
− Select the required device type from the device list.
− Start the Assistant with the “Start” button.
The device settings can now be made without any connected MP85A process
controllers. In the “Save/Load parameters” menu, the settings can be saved to
PC or existing settings loaded for viewing and further processing.

6 Methods of measurement
A measurement start/stop can be implemented manually with the PME
Assistant in individual operation, externally via a digital input or via the field
bus interfaces.
When measurement starts, the measured quantities acquired by the sensors
are written as an x/y value pairs with a time stamp to the internal MP85A
process controller memory and rated as OK or NOK by means of defined
windows, an envelope curve or a tolerance band. In addition, limit value
monitoring can be included in the evaluation. The last measurement curve in
each case can also be instantly plotted and displayed. All processes can be
stored in the background, independently of this display.
6.1 Data reduction
y=f(x)
A measurand Y (force) is recorded and rated as a function of a measurand x
(displacement). The measurement points are also given a time stamp.
Advantage: Intelligent data reduction. Curve points are only generated when
there is a sufficiently large change to x or y. The values nx and ny are user-
selectable.
Fig. 6.1: Force/displacement-driven process curve determination
y=f(t)
A measurand on channel y is recorded as a function of time.
Advantage: There is no need for the X sensor (the displacement sensor on a
press, for example).
Condition: Reproducible feedrates, as otherwise the curve that depends on
them would be shortened or lengthened.
A2392−5.0 enHBM

6.2 Classification
Classifying X or Y
Measured quantities on channel X, such as length, thickness and diameter or
channel Y, such as force, weight, torque, etc., can be divided into 5 groups
per window. This means that e.g. springs can be automatically sorted by
spring rate.
y
max
y
min
Fig. 6.3: Classifying the measurands of a tolerance window
NOTE
Statistics and classification can only be used when using the 31 Flash para-
meter sets, not with memory card or PC parameter sets.
6.3 Monitoring limit values in real time
A total of eight limit values can be assigned and monitored in real time for
channels X and Y. A switching signal of choice can be allocated to each limit
value. This allows a press, for example, to be switched over from “fast” to
“slow”. The circuit logic can also be inverted.
A2392−5.0 en HBM
Page 54
54
MP85A process controller
6.4 Masking out external tolerances
The MP85A process controller can suppress external tolerances, such as
those caused by the differing positioning heights of workpiece holders, e.g.
when the pin being press-fitted is touched. Displacement is set to zero at this
time and a second relative axis is drawn to which the coordinates of the evaluation elements now refer.
Reference point
Dynamic zero point, relative to the force trigger.
When the reference point is reached, displacement is set
to zero. The windows now relate to this zero point.
Fig. 6.4: Reference points for X relative reference of evaluation elements
6.5 Evaluation criteria
The MP85A process controller has different window types to allow a universal
evaluation of the various curve shapes using window techniques. Any mix of
these window types can be used for each measurement curve. An envelope
curve is available if the entire process is to be monitored without a gap.
Fig. 6.5: Evaluation method using tolerance windows
Thread-in window
This checks that the fitting partners thread in correctly and do not fit askew.
A real-time signal indicates that there is a thread-in problem (for example,
window exited at top) and this can be used by the press control to trigger the
return stroke of the press, for example.

Fig. 6.6: Online window
Process window
This window type checks the course of a curve in the window area.
The curve must run through the window as defined from the entry side to the
exit side, without violating any of the other window limits. The entry and the
exit sides are user-selectable (left, right, top, bottom, any).
Fig. 6.7: Process window
Block window
The block window monitors the block size and the block force of a press-fit
process. With this window type, the curve must enter at the given entry side
and must not exit the window. The entry side is user-selectable (left, right, top,
bottom, any).

Thresholds
Thresholds monitor the process continuously in very restricted ranges. The
thresholds can be positioned vertically or horizontally. As an option for
machine safety, these evaluation elements can also monitor the process in
real time and signal the control via a digital output or the field bus.

Fig. 6.9: Thresholds
Envelope curve
The envelope curve continuously monitors the process in max. 4 adjustable
ranges. The process must enter the envelope curve on the one side and exit
on the other. The tolerance width of the envelope curve is freely selectable
and can therefore be adapted to process requirements. Evaluation takes
place at the end of the process.
y

Fig. 6.10: Envelope curve
Tolerance band
The tolerance band covers the complete process. The first to last measurement points must lie within the tolerance band in OK processes (in contrast to
the envelope curve which must be entered and exited). Evaluation takes place
at the end of the process.

Limit monitoring
From firmware version 2.22 and higher, the limit values can also be included
in the total result for process monitoring. This allows, e.g. minimum and
maximum values to be monitored at the start and/or end of a process. This
option is particularly useful in the evaluation methods “Envelope curve” and
“Tolerance band”: The following diagram monitors whether the start and end
of the measurement curve are lying in the yellow marked areas.

6.6 Measurement programs (parameter sets)
A total of 31 measurement programs can be activated from the MP85A
process controller’s internal (flash) memory for 31 different workpieces. A
measurement program comprises a workpiece-specific parameter set
consisting of the settings of the amplifier for the sensor technology, measurement acquisition and storage, function assignments of the digital inputs/
outputs and the evaluation methods.
The parameter sets are loaded from the MP85A process controller flash
memory to the RAM via digital input/outputs, bus commands or the PME
Assistant programs (Chapter 8.6).
CAUTION
Parameter sets may only be switched after the end of a process, not
during a measurement. The next process may only be started once parameter set switching is complete (see Chapter 8.1, Machine control).

TIP:
The optional memory card (MMC(SD card) can store another 1000 parameter
sets in binary data format, in addition to the 31 parameter sets in XML data
format. The function and processing speed is identical for both file types.
Processing the system parameters
The system parameters include the basic settings, interface settings, passcode and settings for data storage and MP85A process controller statistics.
If the parameter sets from the internal Flash-EPROM are used, the system
parameters are identical for all 31 Flash parameter sets and only present
once in the MP85A process controller. If parameter sets from the MMC/PC
card or from PC are used, the system parameters are a component of the
respective parameter set and can therefore be different. This means that, e.g.
different memory settings can be implemented.

7 Switch tester with MP85A(DP)-S EASYswitch
The functions for switch and haptic tests are only available in an
MP85A(DP)-S EASYswitch (switch test version).
7.1 Switch test
All the switching characteristics are recorded by the MP85A(DP)-S EASYswitch and evaluated according to specific features, such as actuating force,
release force, differential force and differential travel.
In addition to these mechanical parameters, the electrical switching point can
also be recorded. To do this, a switch testing type window is placed on the
marked points.
Fig. 7.1: Switch test
Up to 5 switches or switching elements can be checked and evaluated in one
procedure.
It is checked whether the switching of the switch lies within the corresponding
switch test window and whether the specified switching function (make/break)
is met.
The electrical check is implemented via the MP85A(DP)-S EASYswitch digital
inputs. Evaluation takes place at the end of the process.
A2392−5.0 enHBM
Page 61
MP85A process controller
61
NOTE
As the MP85ADP-S only has one digital switch test input, the (virtual) inputs 2
to 5 can be set via PROFIBUS commands and so the switch result displayed,
see MP85A interface description, Chapter 4.
The switch test inputs are available at screw terminals 3 and 4 and are electrically isolated from the internal supply voltage and from the control outputs.
• At screw terminal 3: Control input 1
• At screw terminal 4: Control inputs 2 … 5 (MP85A/MP85A-S only)
An external reference potential (
IN ), to which the control input signals relate,
must be connected for the switch test processes.
The MP85A process controller digital inputs are flank controlled by
transition from 0V to control voltage (e.g. 24V). The set digital input
function is only implemented once with the rising flank. The subsequent
permanent application of the control voltage does not cause a further
action.

Entry and exit sides are not needed for the switch test window type. They can
be monitored with additional process windows.
The switch coordinates displayed in the switch test window, i.e. the coordinates at which the switch changes state, are stored in the statistics. In addition,
“No switching” is signaled for OK or NOK, when the switch does not change
state or when switching is repeated because multiple switching occurs
(chatter).
Switch windows can also be parameterized as windows with defined
sequences. This ensures that on/off switchings are processed in the correct
sequence.
Evaluation follows at the end of the process, i.e. evaluation in real time cannot
be selected.

7.2 Haptic test
The haptic test checks how the switch in this window changes its state, that is,
the “feeling” on actuation. The characteristic values required to do this can be
entered in the haptic test dialog box via the PME Assistant or INDUSTRYmonitor. Any combination or all the characteristic values listed can be tested.
The check is NOK as soon as one of the activated characteristic values is not
OK. The individual characteristic values are clearly shown in the graphic
below.
For the haptic test, the curve must enter and exit the window at the sides and
the window must always be square. It is not possible for the curve to enter or
exit the window at the top or bottom.
TIP:
To secure the process, additional process windows can be set up to evaluate
the process curve in real time and so assist machine protection. If the switch
is defective, limit force switch off is implemented with a reaction time of
approx. 2 ms.
Further information can be found in the online help of the PME Assistant
and the MP85A process controller interface description.

8 Communication with a control system
8.1 MP85A process controller in machine control
Digital inputs/outputs and the CAN, PROFIBUS-DP and Ethernet digital interfaces are available for embedding into a machine control. Both these cases
access the same MP85A process controller device functionality (object table).
Firstly, control commands can be exchanged between the MP85A process
controller and the machine control to ensure that production runs smoothly
and secondly, status information can be exchanged and signals given to the
machine operator. The following signals are available in real time as control
inputs/outputs (e.g. machine protection):

Description
You can set the digital outputs via the SDO
object 2320 (hex), subindex 0. With this option, you can forward individual bits of the Bytes transferred with this object to the relevant
outputs
Allows you to specify the number of a parameter set loaded from the Flash: The parameter set number is output as a binary number
(Bit 0 to Bit 4).
Parameter sets loaded from the MMC/SD
card or PC cannot be queried
You can control the time required for loading a
parameter set with this function: The next process can only be started after switchover
which can take up to 200 ms, the MP85A process controller is only ready for measurement
after switchover. As long as the signal is active therefore, no new process can be started

Implements a transducer test
Loads a parameter set. If, for example, only
three different parameter sets are required,
you can just use two inputs for parameter set
loading, Bit 0* and Bit 1*, you do not need to
assign all bits (parameter set 0 is the default
setting).
Specify via the signal condition whether the
zero value is retained during loading or whether the zero value from the parameter set
should be used.
Specify via data storage whether the device
name is retained during loading or whether
the device name from the parameter set
should be used
Use this input to start/end a process or the
measurement. If you enter further start, stop
or end conditions in the control settings, these
will also apply

digital input available, you can use the four
so-called virtual inputs: The status of the virtual input is set via a PROFIBUS command
(cyclical transmission).
The switching moments are also shown during a haptic test if an input is assigned
Description
There are two methods for process control:
1. With full storage of the process data, i.e. storing curves and results without
loss of data.
2. With a sequence optimized to the process, where, when there is a new
process, data storage is interrupted, so that the next process can be
started again even more quickly.
Both methods are described in the following sections, all signal diagrams are
based on positive circuit logic.
8.2 Test process sequence over time
a) Storing curves and results without loss of data
When you opt for the “without loss of data” storage method and want to save
the curves and/or results on the memory card or externally via the bus, the
following diagrams apply.
The ready signal is then only 1 again, if
− the process is completely finished,
− all the data have been fully stored and
− the device is ready to store the data for the next process.

NOTE
If the process data (curves and results) cannot be stored (because the
memory is full or faulty, for example), the next process cannot be started, as the MP85A process controller does not enable the Ready signal.
When saving data externally to a PC, the PME Assistant or INDUSTRYmonitor must remain open.
b.) Curve and result storage optimized to the process
When you opt for the “storage optimized to the process” storage method and
want to save the curves and/or results on the memory card or externally via
the bus, the following diagrams apply.
The difference between this and “storage without loss of data” is that the
Ready signal can be 1 again, even though the device is not yet ready to store
the new data.
A2392−5.0 enHBM
Page 67

This means that, following an immediate start of a new measurement, the
result and curve files will not be immediately transmitted. So you should only
choose this method if very fast processes have to be monitored and the
results and curves are merely used for spot checks.

8.3 Transducer test
The transducer test can be triggered via the digital input or via the bus signal.
At low filter limit frequencies, the filter settling time must be waited before the
test. A pulse of minimum 5 ms duration at the digital input is necessary for the
transducer test. The result is typically available another 10 ms later.

8.5 Simulation of digital outputs
It can be helpful, particularly during start up or service, to check the system
components and processes downstream of the digital outputs through simulation and activation. The digital outputs of the MP85A process controller can be
activated/deactivated via software commands for this purpose.
The data word configuration to be transmitted for activating/deactivating the
digital outputs depends on the configuration of the data word bits on the digital
outputs.
A2392−5.0 enHBM
Page 69
MP85A process controller
The states of the digital inputs/outputs can be displayed in the “Measured
value display” menu.
Example: Activation of digital output 1
• Set digital output 1 in menu: “Digital outputs” to “Data word bit 0” (circuit
logic: positive).
• Send via a software command (e. g. “SDO terminal”) to address SDO 2320
Index 0 (hex) => 1 (dec): this sets the digital output 1 to High.
• Send data word 0 (dec) to address SDO 2320 Index 0 (hex): deactivates
digital output 1 again.
69
8.6 Parameter sets (measurement programs)
The MP85A process controller has the option to use 31 different measurement programs (parameter sets) and store them power failsafe in internal
flash memory. Another 1000 measurement programs can be saved to the
optional memory card (MMC/SD card).
CAUTION
Parameter sets can only be loaded when no process is running !
The device is only ready for measurement after loading. You can query this
via the signal “Parameter set is loading”.
Parameter sets saved to PC cannot be used by the device or software for the
ongoing operation. They must be saved to the Flash memory or the memory
card.
TIP:
In PROFIBUS-DP mode, the changeover of parameter sets to Flash and the
memory card can also be made in cyclic operation. Further information can be
found in the interface description of the MP85A process controller.
Typically, less than 200 ms are required for the activation of a new parameter
set. At very low filter limit frequencies, the filter settling time must be added. If
you use digital inputs for switching, the switchover occurs when the level
changes at the input (flank).

8.7 Evaluation/storage process times
The MP85A process controller FASTpress can reliably monitor and document
virtually all processes in industrial production. There can be up to 10 cycles
per second without process data storage).
The maximum number of process cycles is guided decisively by:
− the number of process curve measurement points (adjustable)
− the number of evaluation criteria (tolerance window)
− whether process data are to be stored (OK only, NOK only, all)
− whether several MP85A process controllers should be operated in network
(mains load)
− the performance of the storage medium
Some of these points can be specified via the PME Assistant or INDUSTRY-
monitor programs (menu: Set evaluation parameters and Data storage).

Fig. 8.4: Device internal evaluation times (with storage of all data to MMC/SD
card)
Data is transmitted to the memory card with a speed between 2 and
8 kBytes/second, subject to the size of the files to be transferred.
The total storage time results from the process time and the storage time on
the target computer.
CAUTION
If the process data are saved via Ethernet, the storage is dependent on
the network load. This must be taken into account with rapid process
cycle times.
Until all measured value curve data are saved to PC, the files have the file
extension .tmp. Once the data transfer is complete, the files are renamed with
the file extension C85 or D85. This means that downstream software can
clearly detect the storage status and only access the process data once
storage is complete.
Typical process times during production operation in combination with
PLC machine control
The following table shows the times that are approximately required when the
MP85A process controller exchanges cyclical data with a PLC via PROFIBUS, saves data to the MMC/SD card or transmits the data via Ethernet. With
INDUSTRYmonitor software running on the PC. The actually achieved values
depend on the hardware used (PC), the network components (switch) and the
network load. Times can range widely from process to process with Ethernet
in particular due to the latency time.

8.8 Process data storage/production data management
It is possible to store all the process data for quality control purposes. You can
save process curves and/or process results and statistical data (separate
files). The data can be stored internally on the memory card or externally via
the bus interface to a PC. The setting to determine which data is being stored
can be made in the PME Assistant in the “Data protection” area or with the
INDUSTRYmonitor program.
If the data is being stored on the memory card, there are 2 setting variants (in
both cases, data transfer from the memory to the PC followed by visualization
are possible):
1. Ring buffer for the last 1,000 or 10,000 processes
2. Unlimited storage up to the capacity limit of the memory card
Example: With a 2 GByte storage capacity MMC/SD card and standard
process curves approx. 3 kBytes in size, up to 600,000 processes can be
stored.

Internal memory
card
MP85A process controller
The saved process data can also be supplemented with a component designation in the file name and saved in freely selectable directories in the target
system. This enables efficient production data management. The information
is transmitted to the MP85A process controller via the PME Assistant, the
INDUSTRYmonitor or the bus interface.

9 Display-and control options
9.1 DT85 control and display terminal
The DT85 terminal can be used to visualize the process in situ. It is used for
operation with tolerance windows, displaying the courses of curves, results
and statistics. A number of the most important checking and parameterization
functions can be performed as well. However, saving data does not occur in
the DT85 and tolerance bands or envelope curves are not supported.
The black-and-white display is a backlit 1/4” VGA display. The device can
also be connected to existing systems later on. No additional hardware or
software is required to connect it directly to the CAN connection on an MP85A
process controller.
If all the devices are interlinked via CAN, the DT85 has access to all the
devices and can display their information. It can also be connected and
disconnected while operation is ongoing.
Up to 10 MP85(A)
Fig. 9.1: MP85A process controller with the DT85 display terminal
In addition to this, a PC with the PME Assistant can be connected to another
CAN interface on the DT85. The DT85 then works as a gateway and forwards
all the data to the PC. This prevents data collision.
CAUTION
As the MP85A process controller is not Multi-Master-capable and the DT85
functions as a CAN master, the DT85 and software, e.g. the PME Assistant or
INDUSTRYmonitor, should not be operated simultaneously (possible data
collision with data loss).

9.2 FASTpress Suite software
The FASTpress Suite is measurement software for HBM devices of the PME
product family. You can use it to perform a variety of measurement and control
tasks quickly and easily, without the need for programming.
Use the PME Assistant dialogs to quickly parameterize the devices and start the measuring mode.
You can also use the software without a device in “offline” mode to
preconfigure the most important settings or to modify an existing
setup file for later transfer to a device.
Make use of the production software INDUSTRYmonitor and the
EASYmonitor example application provided for the MP85A process controller for rapid entry to production process monitoring.
This enables higher speeds for displaying measured value curves
and data transmission specifically for network operation with several devices. Up to 1000 measurement programs can be stored/
used per process controller.
Create your own applications for the MP85A process controller under programming environments such as C# or VB.NET and integrate them into your target system, or use the provided examples
in the source code (EASYMonitor) and adapt them to your production environment.

MP85A process controller
To store curves and process data during active processes, the storage option in the MP85A process controller must be activated and
one of the applications (PME Assistant, EASYmonitor or INDUSTRYmonitor) must be started on the target computer. However,
only one application at a time may be used by the MP85A process
controller, multi-master capability is not available.
