1 General Information
These operating and assembly instructions contain the following topics:
● General functional description
● Basic safety instructions with declaration of the intended use
● Characteristics
● Assembly
● Installation/Commissioning
● Parameterization
● Error causes and remedies
The operating and assembly instructions are supplementary to other documentation, such as
product data sheets, dimension drawings, etc.
The scope of delivery includes the absolute encoder AMP(H) 41, the operating and assembly
instructions and the Software and Support CD.
The operating and assembly instructions may be requested separately.
1.1 Applicability
These operating and assembly instructions apply exclusively for the following measuring
system series with PROFIBUS-DP interface and PROFIsafe profile:
● AMP 41
● AMPH 41
The products are labelled with affixed nameplates and are components of a system.
The following documentation therefore also applies:
● operator’s operating instructions specific to the system,
● and these operating and assembly instructions
1.2 General functional description
The AMP(H) 41 rotary measuring system is a safe and absolute Multi-Turn position measuring
system with PROFIBUS interface and PROFIsafe protocol.
The measuring system has primarily been designed for use in systems that require safe
position detection.
The safety measuring system consists of a redundant, two-channel system, in which optical
and magnetic scanning units are arranged on a drive shaft, designed as a hollow shaft or
solid shaft.

AMP(H)41_MANUAL-en_R11 - 2019-03-28
Absolute Encoder AMP(H) 41
1.2.1 Main Features
● PROFIBUS interface with PROFIsafe protocol, for transfer of a safe position and speed
● Quick process data channel via PROFIBUS, not safety-oriented
● Additional incremental interface, not safety-oriented
● Two-channel scanning system, for generation of safe measured data through internal
channel comparison
– Channel 1, master system:
optical Single-Turn scanning via code disk with transmitted light and magnetic Multi-Turn
scanning
– Channel 2, inspection system:
magnetic Single and Multi-Turn scanning
● A common drive shaft
Due to its technology the optical system possesses greater accuracy; therefore it is used as
master system. The data of the master system are unevaluated in the non-safety-oriented
process data channel with normal PROFIBUS protocol, but are made available with a short
cycle time.
The magnetic scanning system serves for the internal safety check. The "safe data" obtained
through two-channel data comparison are packed into the PROFIsafe protocol and also
transmitted to the control via the PROFIBUS.
The incremental interface is derived from the master system and is not evaluated in relation to
safety.
1.2.2 Principle of the safety function
System safety results when:
– Each of the two scanning channels is largely fail-safe thanks to individual diagnostic
measures.
– The measuring system internally compares the positions detected by both channels in two
channels, also determines the speed in two channels and transfers the safe data to the
PROFIBUS in the PROFIsafe protocol, see Fig. 1: System diagram “Black Channel” on
page 13.
– In the event of a failed channel comparison or other errors detected through internal
diagnostic mechanisms, the measuring system switches the PROFIsafe channel into error
state.
– The measuring system initialization and execution of the preset adjustment function are
appropriately verified.
– The control additionally checks whether the obtained position data lie in the position window
expected by the control. Unexpected position data are e.g. position jumps, tracking error
deviations and incorrect direction of travel.
– When errors are detected the control introduces appropriate safety measures defined by the
system manufacturer.
– The system manufacturer ensures, through correct mounting of the measuring system, that
the measuring system is always driven by the axis for measurement and is not overloaded.
– The system manufacturer performs a verified test during commissioning and in the event of
any parameter modification.

2.2 General risks when using the product
The product, hereinafter referred to as the measuring system, is manufactured according to
state-of-the-art technology and accepted safety rules. Nevertheless, non-intended use can
pose a danger to life and limb of the user or third parties, or lead to impairment of the
measuring system or other property!
Only use the measuring system in perfect technical condition, and only for its intended use,
paying attention to safety and dangers, and in compliance with the operating and assembly
instructions! Faults which could threaten safety should be eliminated without delay!
2.3 Intended use
The safety measuring system can be used for the detection of angular movement and
processing of measured data for a downstream safety host (F-Host) in systems in which the
goal of "Protection of travel" must be safely achieved. The complete processing chain of the
safety function must then satisfy the requirements of the applied safety standard.
The safety measuring system must only be used in safety applications in conjunction with a
control certified according to the applied safety standard.
The system manufacturer must check that the characteristics of the measuring system satisfy
his application-specific safety requirements. The responsibility or decision regarding the use of
the measuring system lies with the system manufacturer.
Intended use also includes:
● observing all instructions in this operating and assembly instructions,
● observing the nameplate and any prohibition or instruction symbols on the measuring
system,
● observing the operating instructions from the machine/system manufacturer,
● operating the measuring system within the limit values specified in the technical data,
● ensuring that the fail-safe processing unit (F-Host) fulfils all required safety functions,
● observing and using the checklist in the Appendix,
● safe mounting (form-closed) of the measuring system to the driving axis.

NOTES!
To enable the correct measures to be taken in the case of an error, the
following applies:
If no safe position can be output due to an error detected by the measuring
system, the PROFIsafe data channel is automatically put into fail-safe status. In
this status so-called "passivated data" are output via PROFIsafe.
See chapter 9.1 "Output of passivated data (substitute values) in case of
error" on page 75.
Passivated data outputs are:
– PROFIsafe data channel: all are set to 0
– PROFIsafe status: error bit 21 Device_Fault is set
– PROFIsafe-CRC: valid
Upon receipt of passivated data, the F-Host must put the system into a
safe state. It is only possible to leave this error state by eliminating the
error and then switching the supply voltage off and on again!
The process data channel addressable via PROFIBUS is not necessarily
affected by this. If the internal diagnosis in the master channel does not detect
an error, the process data are still output. However, these data are not safe for
the purposes of a safety standard.

26
AMP(H)41_MANUAL-en_R11 - 2019-03-28
Absolute Encoder AMP(H) 41
WARNING!
Deactivation of the safety function through conducted interference
sources!
– All nodes of the safety-relevant communication must be certified according to
IEC 61010 or must have a corresponding EC conformity declaration.
– All PROFIsafe devices used on the bus must have a PROFIBUS and a
PROFIsafe - certificate.
– All safety devices must also have a certificate from a "Notified Body" (e.g.
TÜV, BIA, HSE, INRS, UL, etc.).
– The 24V power supplies used must not cut out in the event of a fault in the en-
ergy supply (safe under single fault conditions) and must fulfil SELV/PELV.
– No stubs lines.
– The shielding effect of cables must also be guaranteed after installation (bend-
ing radii/tensile strength!) and after connector changes. In cases of doubt, use
more flexible cables with a higher current carrying capacity.
– Only use M12 connectors for connecting the measuring system, which guar-
antee good contact between the cable shield and connector housing. The cable shield must be connected to the connector housing over a large area.
– A 5-wire cable with a PE-conductor isolated from the N-conductor (so-called
TN network) must be used for the drive/motor cabling. This will largely prevent
equipotential bonding currents and the development of interference.
– A shielded and stranded data cable must be used to ensure high electromag-
netic interference stability of the system. The shielding should be connected
with low resistance to protective ground using large shield clips at both ends.
The shielding should be grounded in the switch cabinet only if the machine
ground is heavily contaminated with interference towards the switch cabinet
ground.
– Equipotential bonding measures must be provided for the complete pro-
cessing chain of the system.
– Power and signal cables must be laid separately. During installation, observe
the applicable national safety and installation regulations for data and power
cables.
– Observe the manufacturer's instructions for the installation of converters and
for shielding power cables between frequency converter and motor.
– Ensure adequate dimensioning of the energy supply.
5 Installation / Preparation for Commissioning
5.1 Basic rules
Upon completion of installation, a visual inspection with report should be carried out. Wherever
possible, the quality of the network should be verified using a suitable bus analysis tool:
no duplicate bus addresses, no reflections, no telegram repetitions etc.

5.2 PROFIBUS transfer technology, cable specification
All devices are connected in a bus structure (line). Up to 32 clients (master or slaves) can be
connected together in a segment.
The bus is terminated with an active bus termination at the beginning and end of each
segment. For stable operation, it must be ensured that both bus terminations are always
supplied with voltage. The bus termination must be provided externally via the connection plug.
Repeaters (signal amplifiers) have to be used with more than 32 clients or to expand the
network scope in order to connect the various bus segments.
All cables used must conform with PROFIBUS specifications for the following copper data
cable parameters:
The transmission speed for PROFIBUS is selectable in the range between 9.6 Kbit/s and
12 Mbit/s and is automatically detected by the measuring system. It is selected for all devices
on the bus at the time of commissioning the system.
The range is dependent on the transmission speed for cable type A:

WARNING! NOTICE!
Destruction, damage and malfunction of the measuring system in case of
infiltration of foreign substances and damp!
The access to the address switches has to be locked after the settings with the
screw plug. Tighten firmly!
WARNING!
This additional interface is not evaluated in relation to safety and must not
be used for safety-oriented purposes!
– The measuring system checks the outputs of this interface for the feed-in of
external voltages. In the event of voltages > 5.7 V, the measuring system is
switched off for safety reasons. In this state the measuring system behaves
as if it were not connected.
– The interface is generally used as position feedback for motor control applica-
tions.
NOTICE!
Danger of damage to subsequent electronics due to overvoltages caused
by a missing ground reference point!
If the ground reference point is completely missing, e.g. 0 V of the power supply
not connected, voltages equal to the supply voltage can occur at the outputs of
this interface.
– It must be guaranteed that a ground reference point is present at all times,
– or corresponding protective measures by the system operator must be pro-
vided for subsequent electronics.
5.5 Bus addressing
Valid PROFIBUS-addresses: 1 – 99

The device will not start up with an invalid
station address.
The set PROFIBUS address automatically
gives the PROFIsafe destination, see
“F_Source_Add / F_Dest_Add” on page 48.
5.6 Incremental interface
In addition to the PROFIBUS-DP interface for output of the absolute position, the measuring
system also has an incremental interface.

5.6.1 Signal characteristics of incremental interface
When passing through a revolution, a corresponding number of pulses are output. To evaluate
the counting direction, a 2nd signal sequence with a 90° phase offset is output for the control.
The incremental resolution of the measuring system is 4096 pulses/revolution.
No zero pulse is present.

5.6.2 Option HTL-Level, 13...27 V DC
Optionally the incremental interface is available also with HTL levels. For technical reasons, the
user must consider the following boundary conditions at this variant: Ambient temperature,
cable length, cable capacitance, supply voltage and output frequency.
In this case the maximum reachable output frequencies about the incremental interface are a
function of the cable capacitance, the supply voltage and the ambient temperature. Therefore,
the use of this interface is reasonable only if the interface characteristics meet the technical
requirements.
From the view of the measuring system, the transmission cable represents a capacitive load
which must be reloaded with each impulse. In dependence of the cable capacitance, the load
quantity necessary for it varies very strongly. Exactly this reloading of the cable capacitances is
responsible for the high dissipation and heat, which result thereby in the measuring system.
Example: Cable with 75 pF/m, cable length = 100 m, half limiting frequency related to the rated
voltage of 24 V DC: It results a twice as high current consumption of the measuring system.
By the arising heat the measuring system may be only operated with approx. 80% of
the given working temperature.
The following diagram shows the different dependences with respect to three different
supply voltages.
Fixed items are
Capacity of the cable: 75 pF/m
Ambient temperature: 25 °C
Fig. 7: Cable length / Limiting frequencies
Other cable parameters, frequencies and ambient temperatures as well as bearing heat and
temperature increase over the shaft and flange, can produce a considerably worse result in the
practice.
Therefore, the fault-free function of the incremental interface with the application-dependent
parameters has to be checked prior to the productive operation.

6 PROFIBUS / PROFIsafe – Commissioning
6.1 PROFIBUS
PROFIBUS is a continuous, open, digital communication system with a broad range of
applications, particularly in manufacturing and process automation. PROFIBUS is suitable for
fast, time-sensitive and complex communication tasks.
PROFIBUS communication is based on the international standards ICE 61158 and IEC 61784.
The application and engineering aspects are defined in the PROFIBUS User Organization
guidelines. These serve to fulfil the user requirements for a manufacturer-independent and
open system where the communication between devices from different manufacturers is
guaranteed without modifications of the devices.
Important information in this regard can be found in the PROFIBUS Guidelines:
● PROFIBUS guideline: PROFIsafe – Environmental Requirements
Order no.: 2.232
● PROFIBUS Assembly Guideline,
Order no.: 8.022
● PROFIBUS Commissioning Guideline,
Order no: 8.032

Electronic Device Data Sheets (GSD Files)
PLC
PROFIBUS
These and further information on PROFIBUS or PROFIsafe are available from the office of the
PROFIBUS User Organization:
6.1.1 DP communication protocol
The measuring systems support the DP communication protocol, which is designed for quick
data exchange in the field level. The basic functionality is defined by the performance level V0.
This includes cyclical data exchange as well as station and module specific diagnosis.
6.1.2 Device master file (GSD)
In order to achieve a simple plug-and-play configuration for PROFIBUS, the characteristic
communication features for PROFIBUS devices were defined in the form of an electronic
device data sheet (device master file, GSD file).
Using the defined file format, the configuration system can easily read in the device master
data of the PROFIBUS measuring system and automatically take account of it in the bus
system configuration.
The GSD file is a constituent of the measuring system and has the file name HUEB0E3F.GSE.
The measuring system also has three bitmap files called HUEB_BDE.bmp, HUEB_BDI.bmp
und HUEB_BSF.bmp, which it displays in normal mode, in diagnostic mode and in special
operating states.
The files are on the Software and Support CD, order no. ID 21771. It is included in the scope of
delivery.
Fig. 8: GSD for the configuration
Absolute Encoder AMP(H) 41
AMP(H)41_MANUAL-en_R11 - 2019-03-28

6.1.3 PNO ID number
Every PROFIBUS slave and every Class 1 master must have an ID number. This is already
entered in the supplied GSD file.
It is required so that a master can identify the type of the connected device without significant
protocol overhead. The master compares the ID numbers of the devices connected with the ID
numbers of the configuration data specified in the configuration tool. The transfer of user data
only starts once the correct device types have been connected with the correct station
addresses on the bus. This achieves a high level of security against configuration errors.
The measuring system has the PNO ID number 0x0E3F (hex). This number is reserved and is
stored with the PNO.
6.2 PROFIsafe
PROFIsafe is the profile for the transfer of safety-oriented data via PROFIBUS and PROFINET
and is internationally standardized in IEC 61784-3-3.
PROFIsafe is a functional extension of PROFIBUS-DP and was the first communication
standard in accordance with safety standard IEC 61508, which permits standard and fail-safe
communication on one and the same bus line. PROFIsafe devices therefore do not require any
modifications to the existing hardware components, and can be integrated problem-free into
existing systems.
These characteristics are implemented with the "Black-Channel" principle:
● No effect on standard bus protocols
● Independent of the respective transmission channel, whether copper cable, fiber-optic cable,
backplane bus or wireless
● Neither the transmission rates nor the respective error detection play a role
● For PROFIsafe the transmission channels are only "Black Channels"
Fig. 9: „Black-Channel“ principle [source: PROFIsafe system description]
6.3 Measuring system PROFIBUS / PROFIsafe communication
The actual values for position and speed are transmitted in two slots:

● The position actual values of both measuring systems are compared for safe transmission. If
the difference is less than the set monitoring window, the value is considered safe. The safe
position actual value and the calculated safe speed value are transmitted via the PROFIsafe
profile. The part of the control which performs the safety-oriented functions can then process
these values.
● The position actual value and the calculated speed value of the first measuring system are
directly transmitted in the unsafe process data channel. This channel is generally processed
more frequently by the control. This allows normal automation processes to access the
updated position value more frequently.

6.4 Start-up on PROFIBUS
Before the measuring system can be included in the user data traffic (Data_Exchange), the
master must first initialize the measuring system during start-up. The resulting data traffic
between the master and the measuring system (slave) is divided into the parameterization,
configuration and data transfer phases.
It is checked whether the planned nominal configuration agrees with the actual device
configuration. The device type, the format and length information as well as the number of
inputs and outputs must agree in this check. The user is thus reliably protected against data
format errors.
If the check was successful, there is a switch to the DDLM_Data_Exchange mode. In this
mode the measuring system transfers e.g. its actual position

6.6 Configuration
Configuration means that the length and type of process data must be specified and how it is to
be treated.
The measuring system uses a defined number of input and output words on the PROFIBUS,
depending on the configuration. This structure information is already entered for both the
safety-oriented and the non-safety-oriented data in the GSD file, and is described below.
The following definition applies:
Data flow for input data: F-Device F-Host
Data flow for output data: F-Host F-Device
6.6.1 Safety-oriented data, JHG-PROFIsafe module
The module uses five input words for the user data and four input bytes for the PROFIsafe
parameter block.
The module uses four output words for the user data and four output bytes for the PROFIsafe
parameter block.
The Safe-Control Register can only be accessed indirectly via the safety program from an
F-Runtime Group.

Device_Fault: Error in F-Device or F-Module
The bit is set if the value set for the Window increments under the iParameters

CE_CRC: Checksum error in communication
The bit is set if the F-Device detects an F-Communication error, such as e.g. an
incorrect consecutive number (detected via a CRC2 error in V2 mode) or if the
data integrity has been violated (CRC error). The F-Host must then count all
defective messages within a defined time period T and assume a configured safe
status in the event of exceeding the maximum permissible defective messages.
This error can also be triggered by incorrect CRC values in the iParameters
(F_iPar_CRC) or F-Parameters (F_Par_CRC) in the parameterization sequence.
The measuring system reports a parameter error via the PROFIBUS standard
diagnosis and does not start up.

WD_timeout: Watchdog-Timeout during communication
The bit is set if the set watchdog time F_WD_Time in the F-Paramters is

As only 16-bit registers have previously been possible on the control side, the preset value to
be written must be calculated first. The desired preset value must be in the range of 0 to
268 435 455 (28 bit). Together with the measuring system resolution, max. number of steps per
revolution according to type plate (8192), the corresponding values for Preset Multi-
Turn/Preset Single-Turn can then be calculated:
Number of revolutions = desired preset value / steps per revolution
The integer part from this division gives the number of revolutions and must be entered in the
Preset Multi-Turn register.
Single-Turn-Position = desired preset value – (steps per revolution * no. of revolutions)
The result of this calculation is entered in the Preset Single-Turn register.
The preset value is set as new position when the preset adjustment function is executed, see

Number of revolutions: 0…32767 ≙ 15 Bit
The output position does not have a preceding sign.
6.7 Parameterization
Parameterization means providing a PROFIBUS-DP slave with certain information required for
operation prior to commencing the cyclic exchange of process data. The measuring system
requires e.g. data for the integration time, counting direction etc.
Normally the configuration program provides an input box for the PROFIBUS-DP master with
which the user can enter parameter data or select from a list. The structure of the input box is
stored in the device master file. The number and type of parameters entered by the user
depend on the configuration.

6.7.1 F-Parameters (F_Par)
The F-Parameters contain information for adapting the PROFIsafe layer to defined applications
and checking the parameterization using an independent separate method. The F-Parameters
supported by the measuring system are listed below.
Byte order = Big Endian
6.7.1.1 F_Check_SeqNr
The parameter defines whether the sequence number will be included in the consistency check
(CRC2 calculation) of the F-User Data telegram. The parameter is set to "NoCheck" and
cannot be changed. This means that only fail-safe DP standard slaves are supported, which
behave accordingly.
6.7.1.2 F_SIL
F_SIL specifies the SIL which the user expects from the respective F-Device. This is compared
with the locally saved manufacturer's specification. The measuring system supports the safety
classes no SIL and SIL1 to SIL3, SIL3 = standard value.
6.7.1.3 F_CRC_Length
Depending on the length of the F input/output data (12 or 123 bytes) and the SIL level, a CRC
of 2, 3 or 4 bytes is required. In order to check the data, this parameter transmits the expected
length of the CRC2 signature in the safety protocol to the F-Component during start-up. The
measuring system supports the CRC length of 3 bytes. This value is predefined and cannot be
changed.
48
AMP(H)41_MANUAL-en_R11 - 2019-03-28
Absolute Encoder AMP(H) 41
6.7.1.4 F_Block_ID
This parameter specifies whether a CRC should also be formed using the device-specific
safety parameters "F_iPar". As the measuring system supports device-specific safety parameters such as e.g. "Integration time Safe", this parameter is preconfigured with the value "1 =
generate F_iPar_CRC" and cannot be changed.
6.7.1.5 F_Par_Version
The parameter identifies the PROFIsafe version "V2-Mode" implemented in the measuring
system. This value is predefined and cannot be changed.
6.7.1.6 F_Source_Add / F_Dest_Add
The parameter F_Source_Add defines a unique source address within a PROFIsafe cluster.
The parameter F_Dest_Add defines a unique destination address within a PROFIsafe cluster.
The device-specific part of the F-Devices compares the value with the in-situ address switch or
an assigned F-Address, to check the authenticity of the connection.
The PROFIsafe destination address must correspond to the PROFIBUS address
+ 500, set by the address switches implemented in the measuring system, also see chapter
5.5 “Bus addressing” on page 30.
Standard value F_Source_Add = 1, Standard value F_Dest_Add = 503,
F_Source_Add ≠ F_Dest_Add.
6.7.1.7 F_WD_Time
This parameter defines the monitoring time [ms] in the measuring system. A valid current
safety telegram must arrive from the F-Host within this time, otherwise the measuring system
will be set to safe status.
The predefined value is 125 ms.
The watchdog time must generally be set at a level where telegram runtimes are tolerated by
the communication, but it must also allow quick execution of the error reaction function in case
of error.
6.7.1.8 F_iPar_CRC
This parameter represents the checksum value (CRC3), which is calculated from all
iParameters of the device-specific part of the measuring system and ensures safe transmission
of the iParameters. The calculation occurs in a program called "JHG_iParameter" provided by
Johannes Hübner Giessen. The checksum value calculated there must then be manually
entered in the F-Host engineering tool, also see chapter 7 “Parameter Definition/CRC
Calculation“ on page 51.
The measuring system also generates a checksum itself from the iParameters transferred by
the F-Host. This checksum is compared with the checksum transferred by the F-Host in the
measuring system. If both F_iPar_CRC are identical, the measuring system is put into data
exchange mode at start-up, otherwise it does not start up.
To calculate the F_iPar_CRC, the 32-bit CRC polynomial 0x04C11DB7 is used in both the
measuring system and in the JHG_iParameter program.
Standard value = 1132081116, valid for all iParameters with default setting.

6.7.1.9 F_Par_CRC
This parameter represents the checksum value (CRC1), which is calculated from all
F-Parameters of the measuring system and ensures safe transmission of the
F-Parameters. The calculation occurs externally in the F-Host engineering tool and must then
be entered here under this parameter, or is generated automatically.
The CRC1 checksum value is also the start value for the cyclical CRC2 calculation.
The 16-bit CRC polynomial 0x4EAB is used to calculate the F_Par_CRC.
Standard value = 46906, valid for all F-Parameters with default setting.
6.7.2 iParameters (F_iPar)
Application-dependent device characteristics are defined with the iParameters. A CRC
calculation is necessary for safe transmission of the iParameters,
see chapter 7.1 “iParameters“ on page 51.
The iParameters supported by the measuring system are listed below.

6.7.2.1 Integration time Safe
This parameter is used to calculate the safe speed, which is output via the cyclical data of the
PROFIsafe module. High integration times enable high-resolution measurements at low
speeds. Low integration times show speed changes more quickly and are suitable for high
speeds and high dynamics. The time basis is predefined to 50 ms. 50…500 ms can thus be set
using the value range of 1…10. Standard value = 100 ms.
6.7.2.2 Integration time Unsafe
This parameter is used to calculate the unsafe speed, which is output via the process data of
the PROFIBUS module. High integration times enable high-resolution measurements at low
speeds. Low integration times show speed changes more quickly and are suitable for high
speeds and high dynamics. The time basis is predefined to 5 ms. 5…500 ms can thus be set
using the value range of 1…100. Standard value = 100 ms.
6.7.2.3 Window increments
This parameter defines the maximum permissible position deviation in increments of the
master / slave scanning units integrated into the measuring system. The permissible tolerance
window is basically dependent on the maximum speed occurring in the system and must first
be determined by the system operator. Higher speeds require a larger tolerance window. The
value range extends from 50…4000 increments. Standard value = 1000 increments.
6.7.2.4 Idleness tolerance Preset
This parameter defines the maximum permissible speed in increments per Integration
time Safe for performance of the preset function. The permissible speed is dependent on
the bus behavior and the system speed, and must be determined by the system operator first.
The value range extends from 1 increment per Integration time Safe to 5 increments
per Integration time Safe.
Standard value = 1 increment per standard value Integration time Safe.
6.7.2.5 Direction
This parameter defines the current counting direction of the position value looking at the flange
connection, turning the shaft clockwise.
Forward = Counting direction increasing
Backward = Counting direction decreasing
Standard value = Forward

7 Parameter Definition/CRC Calculation
It is best to define the known parameters before configuration in the F-Host, so that they can be
taken into account during configuration.
The procedure, in conjunction with the SIEMENS configuration software SIMATIC Manager
and the optional package S7 Distributed Safety, is described below.
The JHG_iParameter software required for the CRC calculation is a constituent of the
Software and Support CD, order no. ID 21771, see chapter 16.6 “Accessories“, on page 99.
7.1 iParameters
The iParameters are preconfigured with meaningful values in the default setting and should
only be changed if expressly required by the automation task. A CRC calculation is necessary
for safe transmission of the individually set iParameters. This must be performed when
changing the predefined iParameters via the JHG program "JHG_iParameter". The calculated
checksum corresponds to the F-Parameter F_iPar_CRC. This must be entered in the field with
the same name in the Properties – DP slave window when configuring the measuring
system with the hardware configurator, also see chapter 8.3.1 “Setting the iParameters“ on
page 66.
7.1.1 CRC calculation across the iParameters
The predefined standard values are used for the following example of a CRC calculation.
These can be loaded in the JHG_iParameter program using an XML template file. If different
values are required, the standard values can be overwritten by double-clicking on the relevant
entry. The modified parameters can be saved as a complete parameter set or opened again as
a template.
52
AMP(H)41_MANUAL-en_R11 - 2019-03-28
Absolute Encoder AMP(H) 41
Install JHG_iParameter by means of the setup file “JHG_iParameter_setup.exe”.
Start JHG_iParameter by means of the start file "JHG_iParameter.exe", then open the
template file provided with the measuring system with the menu File Open XML template (as example here: AMP41_001.xml).
Modify the relevant parameters if necessary, then click on the Generate CRC switch for the
F_iPar_CRC calculation.
Each parameter change requires a new F_iPar_CRC calculation, which must then be taken
into account in the projection. If a safety program is already present, it must be re-generated.
For further information on the use of JHG_iParameter, refer to the help file with the menu
Info Help.

7.2 F-Parameters
The F-Parameters are already preconfigured with meaningful values in the default setting and
should only be changed if expressly required by the automation task. A CRC which is
automatically calculated by the SIMATIC Manager is necessary for safe transmission of the
individually set F-Parameters. This checksum corresponds to the F-Parameter F_Par_CRC,
which is displayed as a hexadecimal value in the Properties – DP slave window under the
heading Current F parameter CRC (CRC1) when configuring the measuring system with
the hardware configurator: The value A9C3 entered in the example below is valid for the default
setting shown here, also see chapter 8.3.2 “Setting the F-Parameters“ on page 67.
7.2.1 Non-settable F-Parameters
The F-Parameters specified below are either managed by the measuring system or by the FHost, and therefore cannot be manually changed:
● F_Check_SeqNr: NoCheck
● F_CRC_Length: 3-Byte-CRC
● F_Block_ID: 1
● F_Par_Version: V2-mode
● F_Source_Add: 2002 (example value, is predefined by the F-Host)
7.2.2 Settable F-Parameters
It is assumed that the following parameters are configured with their standard values:
● F_SIL: SIL3
● F_Dest_Add: 503 (corresponds to the set PROFIBUS address +500)
● F_WD_Time: 125
● F_iPar_CRC: 1132081116 (calculation by means of JHG tool JHG_iParameter)
Each parameter change gives a new F_Par_CRC value, which is displayed as shown above. If
a safety program is already present, it must be re-generated.

8 Safety Creation – Configuration Example
This chapter describes the procedure for creating the safety program using the SIEMENS
SIMATIC Manager configuration software and the S7 Distributed Safety optional
package.
The safety program is created with the FBD/LAD Editor in STEP 7. The fail-safe FBs and
FCs are programmed in the F-FBD or F-LAD programming language, while the fail-safe DBs
are created in the F-DB programming language. The Distributed Safety F-Library supplied by SIEMENS provides the user with fail-safe application modules, which can be used in
the safety program.
When generating the safety program, safety checks are performed automatically and additional
fail-safe blocks are integrated for error detection and error reaction. This ensures that failures
and errors are detected and corresponding reactions are triggered, which keep the F-System in
safe status or put it into a safe status.
A standard user program can run in the F-CPU in addition to the safety program. The coexistence of standard and safety program in the F-CPU is possible, as the safety-oriented data
of the safety program are protected against undesirable influence by data of the standard user
program.
Data exchange between safety and standard user program in the F-CPU is possible by means
of flags and through access to the process image of the inputs and outputs.
Access protection
Access to the F-System S7 Distributed Safety is protected by two passwords, the
password for the F-CPU and the password for the safety program. A differentiation is made
between offline and online password for the safety program:
● The offline password is part of the safety program in the offline project on the programming
device.
● The online password is part of the safety program in the F-CPU.

WARNING!
Danger of deactivation of the fail-safe function through incorrect
configuration of the safety program!
The safety program must be created in conjunction with the system
documentation provided by SIEMENS for the software and hardware.
Extensive documentation on "Configuring and Programming" a safe
control is provided by SIEMENS in its manual S7 Distributed Safety -
Configuring and Programming, document order number:
A5E00109537-04. This documentation is a constituent of the optional
package S7 Distributed Safety.
The following descriptions relate to the pure procedure and do not take
account of the instructions from the SIEMENS manual.
It is therefore essential to observe and comply with the information and
instructions provided in the SIEMENS manual, particularly the safety
instructions and warnings.
The configuration shown should be taken as an example. The user is
required to check and adapt the usability of the configuration for his own
application. This also includes the selection of suitable safety-oriented
hardware components and the necessary software prerequisites.

Blocks
All fail-safe blocks are shown with a yellow background to distinguish them from blocks of the
standard user program.
8.4.1 Program structure
The safety program is accessed by calling up the F-CALL from the standard user program.
The F-CALL is called up directly e.g. in the cyclic interrupt OB OB 35.
Cyclic interrupt OBs have the advantage that they interrupt the cyclic program processing in
OB 1 of the standard user program at fixed time intervals, i.e. in a cyclic interrupt OB the safety
program is called up and processed at fixed time intervals.
After the safety program has been processed, the standard user program is further processed.
8.4.2 F-Runtime Group
To facilitate handling, the safety program consists of an "F-Runtime Group". The F-Runtime
Group is a logic construct consisting of a number of related F-Blocks, which is formed internally
by the F-System.
The F-Runtime Group comprises:
● one F-Call block F-CALL, "FC1"
● one F-Program block, to which the F-CALL is assigned, "FC2"
● further F-FBs
● several F-DBs
● F-Periphery-DBs
● F-System blocks F-SBs
● automatically generated F-Blocks

All necessary blocks are now displayed in the project window:
8.6 Loading the safety program
When the safety program has been generated, it can be loaded into the F-CPU. It is advisable
to transfer the complete safety program to the F-CPU in STOP operating status. This
guarantees that a consistent safety program is loaded. The program is loaded with the menu
Options Edit safety program Download switch.
8.7 Testing the safety program
After generating the safety program, a complete functional test must be carried out according
to the automation task.
After modifications to an already completely function-tested safety program, it is sufficient to
test the modifications.
9 Access to the safety-oriented data channel
The safety-oriented data channel in the JHG-PROFIsafe module is accessed via the process
image, as with a standard periphery. However, direct access is not permitted. The safetyoriented data channel of the measuring system may only be accessed from the generated FRuntime Group.
The actual communication between F-CPU (process image) and measuring system for
updating the process image occurs concealed in the background, by means of the PROFIsafe
protocol.
The measuring system uses a larger area in the process image in the JHG-PROFIsafe
module, due to the PROFIsafe protocol, than would be necessary for the measuring system
function. The F-Parameter-block contained in the process image is not included in the user
data. When accessing the process image in the safety program, only access to the pure user
data is permitted!

9.1 Output of passivated data (substitute values) in case of error
The safety function requires that for passivation in the safety-oriented channel in the
JHG-PROFIsafe module, the substitute values (0) are used in the following cases instead of
the cyclically output values. This status is indicated via the F-Periphery-DB with
PASS_OUT = 1, see below.
● at start-up of the F-System
● in the case of errors in the safety-oriented communication between F-CPU and measuring
system via the PROFIsafe protocol
● if the value set for the Window increments under the iParameters is exceeded and/or
the internally calculated PROFIsafe telegram is defective
● if the permissible operating temperature range, as defined under the corresponding article
number, is fallen below or exceeded
● if the measuring system is supplied with >36 V DC for longer than 200 ms
● if the measuring system is disconnected in RUN mode, the F-Host is reconfigured and the
measuring system is then reconnected
9.2 F-Periphery-DB
For each F-Periphery, measuring system and digital output module, an
F-Periphery-DB is automatically generated during compilation in HW Config. With
reference to the generated safety program, see chapter 8 “Safety Creation – Configuration
Example“ on page 54, this is block DB1638 for the measuring system and DB1639 for the
digital output module. The F-Periphery-DB contains variables which can be analyzed in the
safety program and can or must be written. An exception is the variable DIAG, which may only
be analyzed in the standard user program. Modification of the initial/current values of the
variables directly in the F-Periphery-DB is not possible, as the F-Periphery-DB is know-how-
protected.
The variables of the measuring system F-Periphery-DB must be accessed in the following
cases:
● during operator acknowledgment of the measuring system after communication errors or
after the start-up phase
● during execution of the preset adjustment function
● when analyzing whether passivated or cyclical data are output
● if the cyclical data of the JHG-PROFIsafe module are to be passivated depending on de-
fined states of the safety program, e.g. group passivation

9.2.1 Measuring system F-Periphery-DB “DB1638” – Overview of variables
9.2.1.1 PASS_ON
With the variable PASS_ON = 1 a passivation of the safety-oriented data of the
JHG-PROFIsafe module can be activated, e.g. depending on defined states in the safety
program. The passivation is not performed directly in the measuring system, instead the status
of these variables is registered by the F-Host and the passivation is only activated by means of
the safety program data. Cyclical data are still output by the measuring system!
If a passivation is performed with PASS_ON = 1, the preset adjustment function is switched off.
9.2.1.2 ACK_NEC
The official application of this variable would be an operator acknowledgment for the measuring
system after F-I/O faults. However, for the measuring system no process is defined, for which
this procedure is permissible. For safety reasons these faults must be removed first and then
the supply voltage must be switched OFF/ON, also see chapter 11 “Troubleshooting and
Diagnosis Options“ on page 82.
Absolute Encoder AMP(H) 41
AMP(H)41_MANUAL-en_R11 - 2019-03-28

NOTES!
No passivation of the measuring system is triggered by IPAR_EN = 1!
With reference to the preset execution, the warning notice contained in the
chapter 10 “Preset Adjustment Function“ on page 80 must be observed!
9.2.1.3 ACK_REI
If a communication error is detected by the F-System for the measuring system, a passivation
of the measuring system is performed.
For the operator acknowledgment of the measuring system after the elimination of errors a
positive edge of variable ACK_REI of the F-Periphery-DB is required, which is linked to the
input of the digital input module I 16.0, symbol name: "RESET".
An operator acknowledgment is required:
● after communication errors
● after the start-up phase
An acknowledgment is only possible if the variable ACK_REQ = 1.
An operator acknowledgment must be provided for each F-Periphery in the safety program via
the variable ACK_REI. This requirement has already been taken into account for the measuring
system and digital output module.
9.2.1.4 IPAR_EN
The variable IPAR_EN is used to execute the preset adjustment function. The process
sequence for execution of this function is described in chapter 10 “Preset Adjustment
Function“ on page 80.
A precise description of when the variables must be set/reset during a re-parameterization of
fail-safe DP standard slaves/IO standard devices can be found in the PROFIsafe Specification
from V1.20, or the documentation on the fail-safe DP Standard Slave/IO Standard Device.
9.2.1.5 PASS_OUT/QBAD/QBAD_I_xx/QBAD_O_xx
The variables PASS_OUT = 1 and QBAD = 1 indicate that a passivation of the measuring system
is present.
The F-System sets PASS_OUT, QBAD, QBAD_I_xx and QBAD_O_xx = 1, while the measuring
system outputs substitute values (0) instead of cyclical values.
If a passivation is performed via the variable PASS_ON = 1, only QBAD, QBAD_I_xx and
QBAD_O_xx = 1 are set. However PASS_OUT does not change its value for a passivation via
PASS_ON = 1. PASS_OUT can therefore be used for the group passivation of further
F-Peripheries.
9.2.1.6 ACK_REQ
If a communication error is detected by the F-System for the measuring system, a passivation
of the measuring system is performed. ACK_REQ = 1 indicates that an operator
acknowledgment for the measuring system is required.
The F-System sets the variable ACK_REQ = 1 as soon as the error has been eliminated and an
operator acknowledgment is possible. After the acknowledgment the variable ACK_REQ is reset
to 0 by the F-System.

9.2.1.7 IPAR_OK
The variable IPAR_OK is used to indicate successful execution of the preset adjustment
function. The process sequence for execution of this function is described
in chapter 10 “Preset Adjustment Function“ on page 80.
A precise description of how the variable can be analyzed in the event of a re-parameterization
of fail-safe DP standard slaves/IO standard devices can be found in the PROFIsafe
Specification from V1.20, or the documentation on the fail-safe DP Standard Slave/IO Standard
Device.
9.2.1.8 DIAG
The DIAG variable provides non-fail-safe information of 1 byte on errors that have occurred, for
service purposes. Access to this variable in the safety program is not permitted!
The coding and use of this variable can be found in the SIEMENS manual
S7 Distributed Safety - Configuring and Programming, document order number:
A5E00109537-04.
9.3 Access to variables of the F-Perhiphery-DB
For each F-Periphery, measuring system and digital output module, an
F-Periphery-DB is generated automatically during compilation in HW Config and a
symbolic name is entered in the symbol table at the same time.
The symbolic name is formed from the fixed prefix "F", the initial address of the F-Periphery
and the name entered for the F-Periphery in HW Config in the Object Properties, max.
17 characters.
Variables of the F-Periphery-DB of an F-Periphery may only be accessed from an F-Runtime
Group and only from the F-Runtime Group from which the channels of this F-Periphery are
accessed, when access is available.
The variables of the F-Periphery-DB can be accessed by specifying the symbolic name of the
F-Periphery-DB and the name of the variable: "fully qualified DB access".
It must be ensured in SIMATIC Manager, that in the FBD/LAD Editor in the menu
Options Customize in the General register the option “Report cross-accesses as error”
is not activated. Otherwise access to variables of the F-Periphery-DB will not be possible.

9.4 Passivation and Operator acknowledgment of the measuring system
9.4.1 After start-up of the F-System
After a start-up of the F-System, the communication between F-CPU and measuring system
via the PROFIsafe protocol must first be established. A passivation of the measuring system
occurs during this time.
During use of the substitute values (0), the variables QBAD, PASS_OUT, QBAD_I_xx and
QBAD_O_xx = 1. The operator acknowledgment of the measuring system, i.e. the output of
cyclical data at the fail-safe outputs, automatically occurs, from the viewpoint of the F-Host,
independently of the setting at the ACK_NEC variable, at the earliest from the 2nd cycle of the
F-Runtime Group after start-up of the F-System. Depending on the cycle time of the F-Runtime
Group and the PROFIBUS-DP, the operator acknowledgment can only occur after a few cycles
of the F-Runtime Group.If the establishment of communication between F-CPU and measuring
system takes longer than the monitoring time set in HW Config in the Object Properties
for the F-Periphery, no automatic operator acknowledgment occurs. In this case a positive
edge of variable ACK_REI of the F-Periphery-DB is required, which is linked to the input of the
digital input module I 16.0, symbol name: "RESET".
9.4.2 After communication errors
If the F-System detects an error in the safety-oriented communication between the
F-CPU and measuring system via the PROFIsafe protocol, a passivation of the measuring
system occurs.
During use of the substitute values (0), the variables QBAD, PASS_OUT, QBAD_I_xx and
QBAD_O_xx = 1.
The operator acknowledgment of the measuring system, i.e. the output of cyclical data at the
fail-safe outputs, only occurs if:
● no further communication errors are present, and the F-System has set the variable
ACK_REQ = 1
● an operator acknowledgment with positive edge of variable ACK_REI of the F-Periphery-
DB has occurred, which is linked to the input of the digital input module I 16.0, symbol
name: "RESET" .

WARNING!
NOTICE!
Danger of death, serious physical injury and/or damage to property due to
uncontrolled start-up of the drive system during execution of the preset
adjustment function!
The relevant drive systems must be locked to prevent automatic start-up.
It is advisable to protect the preset triggering via the F-Host by means of
additional protective measures, such as e.g. key-operated switch, password etc.
The new position must be checked after execution of the preset function.
10 Preset Adjustment Function
The preset adjustment function is used to set the currently output position value to any position
value within the measuring range. The displayed position can thus be set to a machine
reference position purely electronically.
The execution of the preset adjustment function is a critical process, as the resulting actual
value jump, e.g. when using a controller, could cause uncontrolled machine movements. The
preset adjustment function may therefore only be executed when the relevant system part is at
a safe standstill.
After completion of the preset process, you must check that the position output by the
measuring system matches the position transmitted to the measuring system.
The preset adjustment function is already locked in the measuring system and can only be
activated via the variable IPAR_EN in the F-Periphery-DB DB1638. Even if all preconditions are
fulfilled from the viewpoint of the F-Host, the preset adjustment function is only executed when
the shaft of the measuring system is stationary. However, a certain edge jitter, e.g. caused by
machine vibrations, is permitted within a certain tolerance window. This tolerance window can
be set with the iParameter Idleness tolerance Preset, see chapter 6.7.2.4 “Idleness
tolerance Preset“ on page 50.

10.1 Procedure
Prerequisite: The measuring system is in cyclical data exchange.
Write the Preset Multi-Turn and Preset Single-Turn registers in the output data
of the JHG-PROFIsafe module with the desired preset value.
The F-Host must set the variable IPAR_EN in the F-Periphery-DB to 1. With the rising
edge, the measuring system is now switched ready to receive.
With the rising edge of Bit 20 Preset_Request in the Control1 register, the preset value
is accepted. The receipt of the preset value is acknowledged in the Status register by setting Bit 20 Preset_Status.
After receipt of the preset value, the measuring system checks that all prerequisites for ex-
ecution of the preset adjustment function are fulfilled. If so, the preset value is written as
the new position value. In case of error, the execution is rejected and an error message is
output via the Status register by setting Bit 215 Error.
After successful execution of the preset adjustment function, the measuring system sets
the variable iPar_OK = 1 in the F-Periphery-DB and thus indicates to the F-Host that the
preset execution is complete.
The F-Host must now reset the variable IPAR_EN in the F-Periphery-DB to 0. The variable
iPar_OK and Bit 20 Preset_Status in the Status register are thus also reset with the
falling edge. Bit 20 Preset_Request in the Control1 register must be reset manually
again.
Finally, the F-Host must check that the new position corresponds to the new nominal posi-
tion.

11.2 Use of the PROFIBUS diagnosis
In a PROFIBUS system, the PROFIBUS masters provide the so-called host system, e.g. a
PLC-CPU, with process data. If there is no slave on the bus or it is no longer accessible, or the
slave reports a fault itself, the master must notify the host system of the fault in one form or
another. There are several possibilities here, whose evaluation is solely decided by the
application in the host system.
Generally a host system is not stopped by the failure of just one component on the bus, but
must react to the failure in an appropriate way in accordance with the safety regulations.
Normally the master firstly provides the host system with a summary diagnosis, which the host
system reads cyclically from the master, and through which the user is informed of the state of
the individual clients on the bus. If a client is reported defective in the summary diagnosis, the
host can request further data from the master (slave diagnosis), which then allows a detailed
evaluation of the reasons for the fault. The reports obtained in this way can be generated from
the master if the affected slave fails to respond to the master's requests, or they may come
directly from the slave if it reports a fault itself. The generation or reading of a diagnosis report
between the master and slave takes place automatically and does not need to be programmed
by the user.
In addition to the standard diagnosis information, the measuring system provides an extended
diagnosis report with module status information.
11.2.1 Standard diagnosis
The DP standard diagnosis is structured as follows. The perspective is always as viewed from

12 Replacing the Measuring System
The following points must be noted when replacing the measuring system:
● The new measuring system must have the same order number as the measuring system
being replaced; any deviations must be expressly clarified with Johannes Hübner Giessen.
● It must be ensured that the PROFIBUS address set via hardware switch for the new
measuring system matches the previous PROFIBUS address.
● If a bus termination was provided for the measuring system being replaced, this must also be
provided for the new measuring system.
● The new measuring system must be installed in accordance with the specifications and
requirements in chapter 4 “Assembly“ on page 20.
● The new measuring system must be connected in accordance with the specifications
in chapter 5.3 “Connection“ on page 28.
● As the F-Parameters and iParameters of the measuring system are stored in the safety
program of the control, the new measuring system is parameterized with the projected
settings in the start-up phase.
● When recommissioning the replaced measuring system, correct functioning must be ensured
first of all by means of a protected test run.

WARNING!
At inspection of the measuring system and the mounting, the basic safety
instructions contained in chapter 2 must be observed.
The inspection of the measuring system and the mounting must only be carried
out by qualified personnel!
Interval
Inspections
Yearly
Inspect the coupling for damage and ensure it is properly
tightened and free of play.
Ensure the fastening screws are properly tightened.
Check the torque bracket (applies to hollow shaft devices
only): check link heads can move freely. You must be able
to move the link rod manually. If it proves difficult to move,
lightly oil the link rod heads or apply lubricant spray.
After approx. 16 000 –
20 000 hours of operation
or higher levels of
continuous load
Check deep groove ball bearings for noise, running
smoothly. Bearings must be replaced by the manufacturer
only.
15 Maintenance
The device is maintenance-free. However, to guarantee safe and fault-free operations we recommend that you carry out the following inspections of the measuring system and the mounting on a regular basis. Inspections must be recorded in a log book.
