Preliminary information
This guide is designed to provide the most complete and exhaustive information the operator needs to
correctly and safely install and operate the SFA-5000 and SFA-10000 absolute draw-wire encoders
with Profibus-DP interface.
The cable pulling mechanism integrates a 13 x 12 bit absolute multiturn encoder (13 bits = singleturn
resolution = 8,192 cpr; 12 bits = 4,096 revolutions).
SFA-5000/SFA-10000 cable-pulling encoder is aimed at speed and position measurements and controls
in a variety of industrial applications through the movement of a 5,000 mm (196.85”) or 10,000 mm
(393.7”) stainless steel wire. The typical back and forth travel of the moving equipment causes the wire
to reel and unreel and thus the linear movement to be converted into a rotative motion detected by the
encoder which is coupled to the drum.
The stroke per turn is always 200 mm (7.874”), the maximum number of turns is 25 for SFA-5000 and 50
for SFA-10000.
To make it easier to read and understand the text, this guide is divided into two main sections.
In the first section some general information concerning the safety, the mechanical installation and the
electrical connection as well as tips for setting up and running properly and efficiently the SFA-
5000/SFA-10000 cable-actuated encoder are provided.
In the second section, entitled Profibus Interface, you can find detailed information on the Profibus
interface. In this section the interface features and the parameters implemented in the unit are fully
described.

lossary of Profibus terms
PROFIBUS, like many other networking systems, has a set of unique terminology. Table below contains a
few of the technical terms used in this guide to describe the PROFIBUS interface. They are listed in
alphabetical order.
Address (Station) IEC 61158-2: Medium attachment unit identification - unique
number of a station connected to a segment (participant).
Address Space Within PROFIBUS DP the maximum possible number of
addressable network nodes per segment, e.g. 127.
Alarm Notification of an abnormal or unexpected event within a
system. Alarms in PROFIBUS DP require in addition to the
standard diagnosis event mechanism within the cyclic data
exchange a separate acyclic acknowledgement procedure
between a host and a Slave application. Since DP-V1, "Device
related diagnosis" is the basis for the "Alarm" and "Status"
types of diagnosis events (GSD: "DPV1"=1). PROFIBUS DP
defines the following alarm types: Diagnosis, Status, Process,
Update, Pull and Plug Alarm. See "Device Related Diagnosis".
The PNO maintains a Profile Guideline, Part3: Diagnosis,
Alarms and Time Stamping, order no. 3.522.
Alert Alert is a generic term for two different types of notifications
within a PROFIBUS DP/PA network especially arranged but not
exclusively for the process automation:
•alarm;
•event.
Both alert types may be used with or without a user
acknowledgement mechanism. The PNO maintains a PROFIBUS
guideline "Time Stamp", order no. 2.192.
Application Profile Within PROFIBUS a specified agreement within families of
field devices on how to use the general PROFIBUS
communication platform and its subsystems (e.g. device
integration via GSD, EDD, FDT/DTM and Communication
Function Blocks). Communication profiles are not a part of the
PROFIBUS DP application profiles. See "Profile".
Baud rate (Data Rate) Other common terms are "data transfer rate" and
"transmission rate". Within PROFIBUS DP this is the amount of
data transferred across a fieldbus segment per second. A data
rate is measured in units of bits per second ( "b/s" or "bps"), or
baud.
Bus Cycle The period of time the bus Master needs to poll every
participant (Slave) once. More bus Masters can be activated by
using the token principle which consequently prolong the bus
cycle.
Class See “DP Master”, “DP Master Class 1 (DPM1)” and “DP Master

Class 2 (DPM2)”.
Class 1 encoder Encoder class must be set when you configure the device.
Mandatory Class 1 provides the basic functions of the device
and can be used for:
•sending the position value (see Position value
parameter);
•changing the counting direction (see Code sequence
parameter);
•setting the preset value (see Preset value parameter);
•acquiring reduced diagnostic information (see
Diagnostic type parameter = “16 bytes fixed (6+10)”).
Class 2 (+VEL) encoder Encoder class must be set when you configure the device.
Class 2 (+VEL) provides all the Class 1 and Class 2 functions
and additional velocity-related functions:
•transmission of the velocity value (see Position and
velocity values parameter);
•setting of the velocity measuring unit (see Velocity
measure unit parameter).
Class 2 encoder Encoder class must be set when you configure the device.
Class 2 provides all the Class 1 functions and additional
advanced functions such as:
•scaling function (see Scaling function control,
Counts per revolution and Total resolution
parameters);
•extended diagnostic information (see Diagnostic type
parameter = “16 bytes (6+10)” or “63 bytes (6+57)”).
Communication Function
Block (Comm FB)
A basic function block defined for PROFIBUS DP and supplied
by the PLC manufacturer for the standardized access of user
programs to field devices. The standardization is based on IEC
61131-3. The PNO maintains a guideline "PROFIBUS
Communication and Proxy Function Blocks acc. to IEC 61131-
3", order no. 2.182.
Communication
Parameter
Communication parameters are parameters, which adjust the
communication protocol function to the current net
configuration. Communication parameters exist for all phases
of the communication protocols. Examples are bus address,
token rotation time, idle time. See "Slave parametrization" and
"Device parametrization".
Communication Profile IEC 61158 comprises a summary of layer stacks of several
different fieldbusses. IEC 61784 defines the useful
combinations of these stacks via communication profiles
CPF3/1 up to CPF3/3 (PROFINET). One of these is PROFIBUS DP.
Within this communication profile three different physical
profiles are defined:
•RS 485 (RS 485-IS);
•MBP-IS (MBP-LP, MBP);
•Fibre Optics.

Cyclic Data Exchange IEC 61158-3: Term used to describe events which repeat in a
regular and repetitive manner. The MS0 services of PROFIBUS
DP are based on cyclic data exchange. See "State machine".
Cyclic Redundancy Check
(CRC)
Error-checking technique in which the frame recipient
calculates a remainder by dividing frame contents by a prime
binary divisor and compares the calculated remainder to a
value stored in the frame by the sending node.
Data Rate (Baud rate) Other common terms are "data transfer rate" and
"transmission rate". Within PROFIBUS DP this is the amount of
data transferred across a fieldbus segment per second. A data
rate is measured in units of bits per second ("b/s" or "bps"), or
baud.
Decentralized Peripherals
(DP)
The term "Decentralized Peripherals" and the acronym "DP"
stand for the simple, fast, cyclic and deterministic I/O data
exchange between a bus Master and its assigned Slave devices.
The corresponding PROFIBUS communication protocol is
called PROFIBUS DP.
Device Identifier Ident number: The primary device identification is an ident
number of data type Unsigned16. This number is unique and
assigned by the PNO business office upon application. It is
stored within the device and defined in the corresponding
GSD file via keyword. In addition it is part of the GSD file
name. At runtime the ident number is used within:
•the set Slave address procedure;
•the parametrization telegram (octet 5 + 6);
•the standard part of a diagnosis message (octet 5 + 6).
The ident number explicitly cannot be retrieved from a device.
Its main purpose is to make sure that a GSD file and
configuration/parametrization data between Master Class 1
and its Slave are matching. The PNO maintains a technical
guideline "Specification for PROFIBUS device description and
device integration, Volume 1: GSD", Version 5.0, order no.
2.122. For a secondary identification possibility see the
identification & maintenance functions (I&M). See "Ident
Number".
Device Parametrization The device parametrization within PROFIBUS DP consists of
three phases. The first phase takes place during start-up of the
communication system and provides basic communication
parametrization and simple additional device parameters. Both
are defined within the GSD file of a device, stored within a
Master Class 1 after configuration in an engineering tool, and
transmitted to the Slave at start-up time. Most of the
automation cases in factory automation are covered by this
method. More complex devices such as drives, laser scanners,
scales, robots, transmitters, etc. require further individual
parametrization before final production start. This is done in a
second phase. In process automation certain device
parameters such as value limits, value range, gain, etc. need to
be adjusted even at run-time. For this second and third phase

PROFIBUS DP provides two ways to accomplish the task:
DTM/FDT and EDD. See "Slave parametrization" and
"Communication parameter".
Device Profile See "Profile".
DP Master IEC 61158-5: Within PROFIBUS DP a fieldbus node that can be
either Master Class 1 or Master Class 2. A Master Class 1 is a
controlling device which controls several DP Slaves (field
devices). NOTE: This is usually hosted by a programmable
controller or a process controller.
A Master Class 2 is a controlling device which manages
configuration data (parameter sets) and diagnosis data of a DP
Master Class 1, and that additionally can perform all
communication capabilities of a DP Master Class 1.
DP Master Class1 (DPM1) IEC 61158-5: A controlling device which controls several DP-
Slaves (field devices). Usually programmable (logic) controllers
or process control systems are hosts for Master Class 1.
DP Master Class2 (DPM2) IEC 61158-5: A controlling device which manages
configuration data (parameter sets) and diagnosis data of a
DP-Master (Class 1). Additionally the DP-Master (Class 2) can
perform all communication capabilities of a DP-Master (Class
1). Usually personal computers are hosts for DP Master Class 2
for programming, parametrizing, diagnosing and monitoring
purposes.
DP Slave IEC 61158-5: A field device that is assigned to one DP Master
Class 1 as a provider for cyclic I/O data exchange. In addition
acyclic functions and alarms could be supported.
Event Within PROFIBUS DP/PA this is a signal or I/O data or process
value within a certain field device at that point in time where
a trigger condition arises. The values are associated with a
time stamp and stored in a buffer. The time-stamped sample
values are used to archive and visualize significant changes
over the course of the production process. Such an event
mechanism does not prevent from the cyclic transmission of
these signals. A separate event alarm is requesting the transfer
of the events to the main system.
Frame A single set of data transmission from a device.
eneral Station
Description ( SD)
A GSD is an electronically readable ASCII text file and contains
both general and device-specific parameters for
communication and network configuration. By means of
keywords, a configuration tool allows to:
•read device information (manufacturer, type, versions,
bitmaps, etc.);
•read texts for comfortable and easy to use
configuration;
•select transmission rates;
•select modules and their I/O data length
(configuration identifier);

•read texts to assign diagnosis IDs to HMI displays;
•select supported services (freeze, sync, etc.);
from the GSD for the configuration of the device. A GSD
replaces the previously conventional manuals or data sheets
and thus already supports plausibility checks during the
configuration phase. Distinction is made between a device
GSD (for an individual device only) and a profile GSD, which
may be used for devices that comply exactly with a profile
such as a "PA device". GSDs for different languages may be
provided in separate files with corresponding file extensions
(*.gse for English, *.gsg for German, etc.) or altogether in one
file (*.gsd). The device manufacturers are responsible for the
scope and quality of the GSD of their devices.
Ident Number See "Device Identifier".
Notes:
•the ident number is necessary for all DP devices except
for Master Class 2;
•the same ident number may be used for modular
devices as long as the device can be described in the
GSD file as a modular device.
Identifier In general: a symbol that establishes the identity of the one
bearing it. Within this context here it represents an absolute
value of a parameter such as a physical address. It is intended
for systematic and performance handling capabilities within
computer systems, e.g. sorting, consistency checking, physical
localization and alike. Usually an absolute value is associated
with a logical value to represent the particular deployment of
the identifier. Typical abbreviation for identifier is ID.
IEC 61131-3: A combination of letters, numbers and underline
characters, which begins with a letter or underline and which
names a language element. Some of the major identifiers
within PROFIBUS DP are:
- Data type numeric identifier;
- Configuration identifier (Cfg);
- Device identifier (ident number);
- Manufacturer identifier (MANUFACTURER ID);
- Profile ident number (PROFILE ID).
Index IEC 61158-5: Address of an object within an application
process.
The permitted range in PROFIBUS DP is 0 - 255. Indexes are
used to address records of data (parameters, variables, state
information, commands, etc.) within modules of a field device.
PDU (Protocol Data Unit) A packet of data passed across a network via telegrams. The
term implies a specific layer of the OSI seven layer model and
a specific protocol. Each layer has its own PDU that is
extended subsequently from the physical layer up to the
application layer:
•Physical layer protocol data unit (PhPDU);
•Data link protocol data unit (DLPDU);

•Application protocol data unit (APDU).
PI The
PROFIBUS Nutzerorganisation e.V. (PROFIBUS User
Organisation, or PNO) was created in 1989. This group was
composed mainly of manufacturers and users from Europe. In
1992, the first regional PROFIBUS organization was founded
(PROFIBUS Schweiz in Switzerland). In the following years,
additional Regional PROFIBUS & PROFINET Associations (RPAs)
were added. In 1995, all the RPAs joined together under the
international umbrella association PROFIBUS & PROFINET
International (PI). Today, PROFIBUS is represented by 25 RPAs
around the world (including PNO) with over 1400 members,
including most if not all major automation vendors and
service suppliers, along with many end users.

PROFIBUS PROcess FIeldBUS. PROFIBUS is a manufacturer independent
fieldbus standard for applications in manufacturing, process
and building automation. The PROFIBUS family is composed of
three types of protocol, each of which is used for different
tasks. The three types of protocols are: PROFIBUS FMS, DP and
PA.
IEC 61784-1: Communication network according to
communication profile family 3 (CPF3); incorporating
application profiles and system integration aspects like
interfaces and languages for engineering tools and HMI.
PROFIBUS is an open, digital communication system with a
wide range of applications, particularly in the fields of factory
and process automation. PROFIBUS is suitable for both fast,
time-critical applications and complex communication tasks.
The PROFIBUS logo is a registered trademark.
PROFIBUS DP Acronym for "PROFIBUS for Decentralized Peripherals".
Specification of an open fieldbus system with the following
characteristics:
•polling Master-Slave-system (cyclic communications,
MS0);
•flying Masters with robin round token passing
coordination (MM);
•connection based (MS1) and connectionless (MS2,
MS3) acyclic communication between Masters and

Slaves.
Options (e.g.):
•Data exchange broadcast (DXB), i.e. Slave to Slaves
communication;
•isochronous mode of Slaves;
•clock synchronization;
•redundancy.
PROFIBUS DP is standardized within IEC 61158 and IEC 61784,
communication profile families 3/1 and 3/2. The term
"PROFIBUS DP" is also a synonym for the RS-485 based
deployments within factory automation.
PROFIdrive Communication technology especially adopted to the
requirements of position and speed controlled drive
applications (e.g. speed synchronized axis). Within the scope of
PROFIBUS, "PROFIdrive" is used for the application of the
PROFIBUS DP protocol (DP-V2) in motion control automation
together with the corresponding application profiles
("PROFIdrive - Profile for variable speed drives" and
"PROFIdrive - Profile drive technology") for the transmission
technology RS-485.
Profile Besides other things profiles in common define agreements on
how to use communication means in a standardized manner.
Within the context of fieldbusses several types of profiles are
known:
•communication profiles (e.g. IEC 61784);
•physical profiles (MBP-IS, RS-485);
•application profiles (see PROFIBUS TC3);
•device profiles (e.g. robots);
•branch profiles (e.g. extruder).
Profile Ident Number Identifier of a particular profile definition. The profile ident
number is taken from the pool of ident numbers handled by
the PNO. It plays a role within the following scenarios.
(1) In cases where the device of a manufacturer A should be
replaceable by an equivalent device, the PNO is assigning
number ranges to dedicated device types (Profile specific IDs)
in combination with certain "Profile GSDs". Profiles using this
methodology are e.g. "PA Devices" and "PROFIdrive".
(2) Usually these Slave devices are designed to communicate
with a Master Class 2 application (e.g. profile application or
profile DTM). In order to ensure a Master application is
communicating with an appropriate Slave, it is sending a
profile specific ID during the establishment of the connection
(MS2 Initiate Service). The Slave may answer with the same
profile specific ID (if it is supporting this profile), with another
ID (if it is supporting another profile) or with "0000h" if it is
not supporting any profile.
(3) I&M functions: Besides its basic I&M information devices -
following a certain profile - are enabled to provide more
detailed profile specific information.

Protocol Data Unit (PDU) A packet of data passed across a network via telegrams. The
term implies a specific layer of the OSI seven layer model and
a specific protocol. Each layer has its own PDU that is
extended subsequently from the physical layer up to the
application layer:
•Physical layer protocol data unit (PhPDU);
•Data link protocol data unit (DLPDU);
•Application protocol data unit (APDU).
Slave Parametrization For a DP Slave several levels of parametrization exist.
(1) The parameters on the DP communication level can be
defined via a GSD file and comprise features such as baud
rates, timing constraints, identification, options, transferable
data structures, publisher subscriber links, etc. This level
supports parametrization of simple modular Slaves and also
special common additional communication layers such as
PROFIsafe. This parametrization is fixed for a given operational
life cycle after start-up.
(2) More complex devices may be parametrized via EDD and/or
FDT/DTM technology via an acyclic communication service
(MS2).
(3) For parameter changes at run-time such as batch
operation (recipes) or motion control, special "parameter
channels" associated with the cyclic data structures may be
added or the MS1 services together with proxy function blocks
may be used.
State Machine (DP) An abstract machine consisting of a set of states (including
the initial state), a set of input events, a set of output events,
and a state transition function. A state machine describes the
behaviour of a field device how to react in different situations.
The state machine for DP Slaves comprises the following
states/actions:
- Power_On_Reset --> Set Slave address --> if successful, a
transition follows to:
- Wait_Prm --> Parametrization, diagnosis (optional) --> if
successful, a transition follows to:
- Wait_Cfg --> Configuration, diagnosis (optional) --> if
successful, a transition follows to:
- Data_Exch --> Normal operation: cyclic data exchange.
On top of this basic communication layer state machine
application profiles are defining their own additional state
machines, e.g. PA devices, PROFIdrive, PROFIsafe, Ident
Systems, Weighing and Dosage Systems.
State machines are best modelled and documented with the
help of the "Unified Modelling Language (UML)".
Station Address Within PROFIBUS DP the address of a communication
participant (Master or Slave). The permitted range is 0 to 127,
with:
- 126 intended to be used for the "soft" addressing of Slave
devices;
- 127 intended to be used for broadcast messages to all the

Slaves.
Topology In a communication network, the pattern of interconnection
between network nodes; e.g. bus, ring, star configuration.
Transmission Rate (Baud
rate)
The signalling rate of a digital communication line. It is the
switching speed, or number of transitions (voltage or
frequency changes) that are made per second. Within
PROFIBUS DP the possible transmission rates depend on the
MAU (Medium Attachment Unit) in use.
Watchdog Control IEC 61158-6: This timer is part of the DP layer within a Slave. It
is restarted by received requests from the bus Master and will
set the outputs of a Slave to a fail-safe state after the
expiration of the timer.
Watchdog Time (Twd) IEC 61158-5: The watchdog timer is part of the DP layer within
a Slave. The watchdog time is set by parametrization at run-
up and consists of a watchdog time base (1 or 10 ms) and 2
factors. A selection can be made during configuration via the
GSD file of a Slave. This is a Slave parameter. See "Watchdog
control".

•connect according to explanation in the ”Electrical connection” section;
•in compliance with 2014/30/UE norm on electromagnetic
compatibility, following precautions must be taken:
-before handling and installing the equipment, discharge
electrical charge from your body and tools which may come in touch
with the device;
- power supply must be stabilized without noise; install EMC filters on
device power supply if needed;
- always use shielded cables (twisted pair cables whenever possible);
- avoid cables runs longer than necessary;
- avoid running the signal cable near high voltage power cables;
- mount the device as far as possible from any capacitive or inductive
noise source; shield the device from noise source if needed;
- to guarantee a correct working of the device, avoid using strong magnets
on or near by the unit;
- minimize noise by connecting the shield and/or the connector housing
and/or the frame to ground. Make sure that ground is not affected by

noise. The connection point to ground can be situated both on the device
side and on user’s side. The best solution to minimize the interference
must be carried out by the user. Provide the ground connection as close
as possible to the encoder. We suggest using the ground point provided
in the cap, use one TCEI M3 x 6 cylindrical head screw with two tooth
lock washers.
1.3 Mechanical safety
•Install the device following strictly the information in the “Mechanical
installation” section;
•mechanical installation has to be carried out with stationary mechanical
parts;
•do not disassemble the unit;
•do not tool the unit;
•delicate electronic equipment: handle with care; do not subject the device
to knocks or shocks;
•respect the environmental characteristics of the product;
•we suggest installing the unit providing protection means against waste,
especially swarf as turnings, chips, or filings; should this not be possible,
please make sure that adequate cleaning measures are in place in order to
prevent the wire from jamming;
•to avoid failures, never exceed the maximum measuring length and
prevent the wire from tangling up;
•never release the wire freely, always help the wire wind properly: risk of
personal injury and/or equipment damage;
•always keep the wire aligned not to damage the equipment;
•the stroke per turn of the draw-wire unit is 200 mm (7.874”).
