2 Basic safety information
DANGER!
This section provides an overview of all significant safety aspects necessary to
protect personnel and ensure safe, fault-free operation of the function module.
Failure to observe this information may result in significant danger.
2.1 Responsibility of the operator
The function modules are used in a commercial capacity. The operator of the function modules,
therefore, is subject to statutory occupational safety requirements and the safety, accident pre-
vention and environmental regulations applicable to the areas in which the function modules are
used.
2.2 Selecting and qualifying personnel; basic obligations
All work on function modules may be carried out only by qualified personnel. Qualified per-
sonnel are personnel with the training, experience, and instruction, as well as expertise on
relevant standards, specifications, accident prevention regulations and operating circum-
stances necessary to carry out the required work, and who have been authorised to do so
by the persons responsible for the safety of the system. They are able to identify and avoid
potential hazards.
In addition, please see standards VDE 0105-100 and IEC 364 for the definition of “qualified
personnel” (reference, e.g. Beuth Verlag GmbH, VDE-Verlag GmbH)
Responsibilities for assembly, installation, commissioning and operation must be clearly de-
fined. Personnel who are receiving instruction or training must be supervised.
2.3 Proper use
The SPN must be used in conjunction with the USL(H) 42 basic device and the UO-SCU.
The system manufacturer must review whether the properties of the function module fulfil the
safety requirements in its specific application. The system manufacturer is responsible for use of
the function module and for deciding whether to use the module. Function modules are de-
signed for unsupervised, continuous operation.
Proper use also includes:
observing all information in this operating and assembly manual
observing type plates and any prohibition or information signs
observing the operating manual of the machine or system manufacturer
operating the function module within the limits stipulated in the technical data
not engaging in improper use

Use for medical purposes.
2.5 Safety information
WARNING! ATTENTION! NOTE!
Destruction, damage or impact to the function of the function module.
Only complete wiring work and only connect or disconnect electrical connections
when the module is powered down.
Review any potential hazards due to interactions with other systems and devices
currently installed in the surrounding area, or which are to be installed. The user
is responsible for taking relevant measures.
The power supply must be secured with a fuse appropriate for the diameter of the
intake line.
Cables used must be suitable for the temperature range.
Defective function modules may not be operated.
Opening function modules is prohibited.
The type plates specify the technical properties of the function modules. If a type
plate is no longer legible, or if a type plate is missing entirely, the function module
may not be operated. Contact Hübner service (see page 2).

3 Assembly
3.1 Safety information
WARNING!
Assembly and disassembly may only be carried out by qualified personnel.
In general, the requirements and acceptance conditions for the system as a
whole must be observed.
DANGER! ATTENTION!
Danger of death, severe physical injury and/or property damage due to
deactivating safety functions, caused by an unsecured shaft drive.
In general, the requirements and acceptance conditions for the system as a
whole must be observed.
3.2 Basic regulations
WARNING!
Power and signal lines must be installed separately.
Observe the manufacturer’s information when installing converters, shielding on
power lines between the frequency converter and motor.
Ensure the energy supply is sufficient for the application.
3.3 Replacing function modules
When replacing function modules, observe the following:
The new function module must have the same item no. (ID) as the old one.
When using a new measurement system, the operator must ensure that the PROFIsafe tar-
get address set via hardware switches is the same as the previous address.
Since the F parameter and iParameter of the measurement system are saved in the secu-
rity program for the controller, the new measurement system is configured with the project-
specific settings in the start-up phase.
If the project does not support neighbourhood detection, then the previously assigned de-
vice names must be assigned to the new measurement system as well during the ex-
change. The device name is recognised when the system starts up, and the new MAC ad-
dress and IP address are automatically assigned to the device name.
When recommissioning the replaced function module, a secure test run must be completed
first to ensure it functions correctly.

PROFINET IO transmission technology, cable specification
Safety- related PROFIsafe communication, as well as PROFINET communication, are transmit-
ted via the commonly used network.
PROFINET supports line, tree and star structures. The bus or line structure used in field buses,
therefore, is also available for Ethernet. This is especially practical when wiring systems, since

UO-SPN-1
Operating and configuration manual
UO-SPN1_Manual-en_R4
13
lines and stubs can be combined. Since the US 42-PROFINET module already has an inte-
grated switch, the line topology can be easily created.
Only cables and plug connectors for which the manufacturer has issued a PROFINET manufac-
turer declaration may be used. Line type A/B/C, mechanical and chemical properties, and the
design of the PROFINET cable must be selected according to the automation task in question.
The cables must be designed for bit rates of up to 100 MBit/s. The transmission speed is de-
tected automatically by the USC 42 PROFINET module, and does not have to be set using a
switch.
Bus addressing via switches, as in the PROFIBUS-DP, is likewise not necessary, as this is han-
dled automatically by the addressing features of the PROFINET controller, however, the
PROFIsafe target address “F_Dest_Add” must be set, see section 5.4.1.6.
The cable length, including patch cable, may be a max. of 100 m for copper cabling between
two devices. This transmission path is defined as the PROFINET-End-to-end-link. The number
of detachable connections within the end-to-end-link is limited to six pairs of plug connectors
(plug/socket). If over six pairs of plug connectors are required, the maximum permitted damping
values (channel class D values) for the entire transmission path must be complied with.
NOTE!
With IRT communication, the topology is planned in a wiring table. Ports 1 and 2
must be connected correctly.
This is not the case for RT communication, which can be wired freely.

Device classes
The following device classes are differentiated in a PROFINET IO system:
IO-Controller
For example, a PLC that addresses the connected IO device.
IO-Device
Decentrally located field device (measurement system) that is assigned to one or more IO
controllers and transmits alarms in addition to process and configuration data.
IO-Supervisor (Engineering Station)
A programming device or industrial PC that has access to all process and parameter data
at the same time as the IO controller.
Device description file (XML)
The GSDML file and associated bitmap file are part of the measurement system: "GSDML-
V2.3-HU-024A-AMPN(H)41-aktuelles Datum.xml".
The files are included on the software and support CD. This is part of the delivery.
Device identification
Each PROFINET-IO device has a device identification. This consists of a company designation,
vendor ID, and a manufacturer-specific part, the device-ID. The vendor ID is assigned by the
PNO; this ID is 0x024A for Johannes Hübner - Fabrik elektrischer Maschinen GmbH, and the
device ID is 0x03E8.
The planned device identification is reviewed during start-up, in order to detect errors in the pro-
ject planning.

UO-SPN1_Manual-en_R4
Address assignment
Parameter
Standard
value
Description
MAC
address
–
The measurement system has a
stored MAC address upon delivery as a standard feature. This is
printed on the device's type plate,
e.g. “00:03:12:04:00:60”, and cannot be modified.
Device type
AMPN(H)41
The name of the device type is “AMPN(H)41” and cannot be
changed.
Device
names
–
Before an IO device can be addressed by an IO controller, it must
have a device name, since the IP address is permanently
assigned to the device name. The IO controller can also assign
IP addresses to IO devices during start-up according to their
device names. The advantage of this process is that names are
easier to handle than complex IP addresses.
Assigning a device name to a specific IO device is comparable to
setting the PROFIBUS address for a DP Slave.
The measurement system does not have any stored device
names upon delivery, or after a reset. The measurement system
can only be addressed by an IO controller after a device name is
assigned using the engineering tool, for instance to transmit
project planning data (such as the IP address) during start-up, or
for user data exchange during cyclical operation.
The name is assigned before commissioning by the engineering
tool via the DCP protocol used as a standard on PROFINET-IO
field devices.
IP address
0.0.0.0
The measurement system does not have a stored IP address
upon delivery, or after a reset.
Standard value: “0.0.0.0”
Subnet
mask
0.0.0.0
The measurement system does not have a stored subnet mask
upon delivery, or after a reset.
Standard value: “0.0.0.0”
Process for assigning device names and addresses to an IO device:
Determine the device name, IP address, and subnet mask. However, this may also be done
automatically depending on the configuration of the IO controller.
The device name is assigned to an IO device (MAC address) –transmit the device name to
the device
Load project plan to the IO controller
The IO controller assigns IP addresses to the device names during start-up. Assignment of
IP addresses can also be switched off; in this case, the available IP address in the IO
device is used.

5.2 Start-up on the PROFINET IO
Following a successful start-up, IO devices will independently begin data transmission. A
PROFINET-IO communication relationship always follows the provider-consumer model. During
cyclical transmission of the measured value, the IO device is the provider of the data, while the
IO controller (such as a PLC) is the consumer. The transmitted data is always assigned a status
(good or bad).

The speed is output as a signed two's complement value.
Setting the direction of rotation = Forward
In light of the flange mounting, turning the shaft clockwise:
positive speed output
Setting the direction of rotation = Reverse
In light of the flange mounting, turning the shaft clockwise:
negative speed output
If the measured speed exceeds the display range of -32768…+32767, this will cause an overrun
reported in the cam register via Bit 20. At the time of the overrun, the speed will remain stopped
at the respective +/- maximum value until it is back in the display range. In this case, the mes-
sage will also be deleted from the cam register. The speed is indicated in increments per in-
tegration time Safe.

The number of revolutions is noted in the Multi-Turn tab, while the current Single-Turn posi-
tion in steps is noted in the Single-Turn tab. The position can be calculated alongside the
resolution of the measurement system, max. number of steps per revolution according to the
type plate:
Position in steps = steps/revolution x number of revolutions + Single-Turn position
Steps per revolution: 8192 ≙13 Bit Number of revolutions 0…32767 ≙15 Bit

Description

iPar_OK: New iParameter values have been assigned to the F-Device.
This bit is set when a Preset query has been successfully completed via the F-Host
(Bit iPar_EN), see also section 9.
21
Device_Fault: Error in the F-Device or F-module
This bit is set when the value set under the iParameters for window increments has
been exceeded, and/or the internally calculated PROFIsafe telegram is faulty. The
measurement system is then transitioned to a failsafe state, and outputs its passiv-
ated data. This state can only be exited by correcting the error and supply voltage
OFF/ON.
2²
CE_CRC: Checksum error in communication
This bit is set when the F-Device detects an F communication error, for instance a
missing serial number (detected via a CRC2 error in V2 mode) or if data integrity
has been violated (CRC error). The F-Host is then requested to count all faulty
messages within a certain time T and, if the maximum permitted number of faulty
messages has been exceeded, to enter a configured safe state.
This error can also be triggered by incorrect CRC values in the iParameters
(F_iPar_CRC) or F-Parameters (F_Par_CRC) in the configuration sequence. The
measurement system reports a parameter error via PROFINET standard diagnosis,
and does not start up.
