1. Introduction
This manual describes the implementation and
configuration of an absolute rotary encoder with
PROFINET interface. The device fulfills the
requirements of a PROFINET IO device with RT
(real time) or IRT (isochronous real time)
classification.
1.1 Absolute rotary encoder
The basic principle of an absolute rotary encoder is
the optical sampling of a transparent code disc
which is fixed with the driving shaft.
The absolute rotary encoder has a maximum
resolution of 65,536 steps per revolution (16 bits).
The mutli-turn version can detect up to 16,384
revolutions (14 bits). Therefore the largest resulting
resolution is 30 bits = 230 = 1,073,741,824 steps.
The standard single-turn version has 13 bits, the
standard multi-turn version 25 bits.

or the setup of a PROFINET network please, refer

1.2 PROFINET technology
PROFINET is an Industrial Ethernet standard
merging plant automation with other enterprise IT
resources.
It provides comparable functionality to PROFIBUS
with techniques used by engineering, IT, and
management personnel.
Established IT standards are employed as basis of
communication: TCP, UDP, IP. XML is used as
description language for device profiles (GSDML
files).
Two ways of using PROFINET are available:
PROFINET IO, similar to PROFIBUS DP as a
distributed I/O system and PROFINET CBA as a
modular component-based system for larger
systems.
PROFINET offers scalable communication for
different applications in industrial automation:
PROFINET NRT (non real time) is suited
for non-time-critical process automation
with clock rates of roughly 100 msec.
PROFINET RT (real time) offers a
communication channel with optimized
performance (10 msec clock rate) for
most factory automation tasks
PROFINET IRT (isochronous real time)
employs special communication hardware
to enable clock rates of less than 1 msec
and a jitter precision of less than 1 µsec.
This channel is mainly of use for motion
control applications.
PROFINET IO uses a view of distributed I/O similar
to PROFIBUS DP. IO controllers (e.g. PLCs) run
an automation program, IO devices (e.g. absolute
encoders) are remotely assigned field devices, and
IO supervisors (e.g. programming devices) are
used for commissioning and diagnostics.
The engineering of PROFINET IO is done similar
to PROFIBUS. The field buses (i.e. Ethernet
topologies) are assigned to control systems during
configuration. The IO device is configured in the
actual system based on the contents of its GSDML
file.
After completion of the engineering the installer
loads the data for the expansion into the IO
controller (PLC) and the IO controller assumes
data exchange with the IO device.
An IO device is addressed within PROFINET (and
also possibly by external IT components) through
its IP address.
Data can be exchanged from the IO controller to
the IO device (and vice versa) cyclically (for
process data). Apart from this, parameter data can
be exchanged acyclically during engineering of the
IO device or by the use of PLC programming
blocks.

2. Installation
2.1 Electrical Connection
The rotary encoder is connected by a 4 pin M12
connector for the power supply and two 4 pin,
D-coded M12 connector for Ethernet.
The Encoder uses a second D-coded connector
and provides integrated switch functionality. On or
in the packaging of the connector is the mounting
description.

2.5 Instructions for mechanical installation and electrical connection of the rotary encoder
The following points should be observed:
Do not drop the angular encoder or
subject it to excessive vibration. The
encoder is a precision device.
Do not open the angular encoder housing
(this does not mean that you cannot
remove the connection cap). If the device
is opened and closed again, it can be
damaged and dirt may enter the unit.
The angular encoder shaft must be
connected to the shaft to be measured
through a suitable coupling (full shaft
version). This coupling is used to dampen
vibrations and imbalance on the encoder
shaft and to avoid inadmissible high
forces. Suitable couplings are available
from Posital.
Although Posital absolute encoders are
rugged, when used in tough ambient
conditions, they should be protected
against damage using suitable protective
measures. The encoder should not be
used as handles or steps.
Only qualified personnel may commission
and operate these devices. These are
personnel who are authorized to
commission, ground and tag devices,
systems and circuits according to the
current state of safety technology.
It is not permissible to make any electrical
changes to the encoder.
Route the connecting cable to the angular
encoder at a considerable distance or
completely separated from power cables
with their associated noise. Completely
shielded cables must be used for reliable
data transfer and good grounding must be
provided. Cabling, establishing and
interrupting electrical connections may
only be carried-out when the equipment is
in a no-voltage condition. Short-circuits,
voltage spikes etc. can result in erroneous
functions and uncontrolled statuses which
can even include severe personnel injury
and material damage.
The encoder should have got a large-area
connection to PE. If the flange don’t have
a good electrical connection to the
machine –i.e. if there was used a plastic
mounting device –then use i.e. a 30cm
long and 2cm wide copper tape to get the
PE connection.
Before powering-up the system, check all of the
electrical connections. Connections, which are not
correct, can cause the system to function
incorrectly. Fault connections can result in severe
personnel injury and material damage.

3.4.1 Format of actual position values
G1_XIST1 and G1_XIST2 are the actual position
values in binary. For absolute encoders one
format example is given below. NOTE: the
alignment in the data-frame (left or right-aligned)
is considered for each individual resolution.
Example: 25 bit Multiturn absolute encoder
(8192 steps per revolution, 4096 distinguishable
revolutions).
All values are presented in binary format
The shifting factors in P979 "sensor format"
display the actual format. The default setting is
G1_XIST1 left aligned and G1_XIST2 right
aligned.
The settings in the Encoder parameter data
affect the position value in both G1_XIST1 and
G1_XIST2.
G1_XIST2 displays the error telegram instead
of the position value if error occurs.
P979, Subindex 3 (Shift factor for G1_XIST1)

3.8 Rotary encoder functions –data format
PROFINET IO devices are set up in modules.
Each module can be plugged in physical and/or
logical slots. These are subdivided into sub slots
individually to accommodate further data hierarchy.
One sub slot can contain several cyclic
input/output channels as well as acyclic record
channels (used for parameters).
There are two versions of PLC available. Some of
them support only one sub slot. Other ones i.e. S7
400 support several sub slots. To work with both
PLCs there are in the GSDML-file two directories:
Standard and Encoder Profile 4.
POSITAL rotary encoders offer for the standard
profile one slot (address #0) with one sub slot
(address #0) for all device data for old PLC’s that
doesn’t support several sub slots.
Device parameters are grouped together as
records in the PROFINET interface. The following

3.9.1 Code sequence
The parameter “code sequence“ defines the
counting direction of the position value. The code
increases when the shaft is rotating clockwise
(CW) or counter-clockwise (CCW) (view onto the
shaft).

3.9.3 Preset control for G1_XIST1
The parameter “preset control“ defines the preset
functionality. If parameter Class 4 is activated and Preset control is disabled then the Preset will not
be affected for G1_XIST1.
