3.3 Supported Standards and Protocols
The encoders of the M36X8/M58X8 series support the IO-Link protocol according to the follow-
ing standards:
• IO-Link Interface and System Specification V1.1.2
• IODD Version V1.1

3 Product Description Kübler Group
8 - EN Manual IO-Link interface - R67071.0002 - 02
• IO-Link Common Profile V1.0
• IO-Link BLOB Transfer & Firmware Update V1.1
The device description file (IODD) can be downloaded from the website of the device manufac-
turer (Contact) or by means of the IODD finder on the IO-Link website.
3.4 Interface Description
IO-Link is a brand name. The original designation of this communication system is SDCI and is
described in Section 9 of European Standard EN 61131 (Single-drop digital communication in-
terface for small sensors and actuators).
IO-Link is not a field bus. It is based on the conventional 3-wire connection for sensor and ac-
tuator(s) and is thus compatible with the existing 3-wire system with switching sensors in today's
machines and facilities.
An IO-Link configuration can be operated as a standalone installation for the communication
between PLC and devices. But it can also be integrated in other field bus networks such as e. g.
ProfiNet, EtherCAT, EtherNet/IP with 100% backwards compatibility. This results in the system
structure shown in the illustration.
9007199389068555
Since IO-Link achieves a serial point-to-point communication, the star topology is the only
device architecture that can be realized. IO-Link devices (hubs) with an expansion port are an
exception. The IO-Link device communicates point-to-point via a standard sensor cable with an
IO-Link master. The IO-Link master combines the data with other IO-Link devices and commu-
nicates with the control via an industrial network or a backplane.
The IO-Link communication thus allows transmitting one or several measured or analog values
in addition to the switching signal. A plurality of switching points or a mix of analog and digital
data can also be transmitted.

Kübler Group 3 Product Description
Manual IO-Link interface - R67071.0002 - 02 EN - 9
Usual field bus or Ethernet software tools can be used for parameterizing and centralized data
storage of the IO-Link devices. There are also dedicated IO-Link tools. The corresponding de-
scription files of the IO-Link devices (IODD) are stored centrally on the so-called IODD finder.
IO-Link has two logical data channels, which separate the cyclic and the acyclic data. The IO-
Link communication takes place continuously between the control and the IO-Link devices. It al-
lows accessing to all process data, diagnostic data and device information. Device-specific data
is also accessible. It is thus also possible to access to the actuators and sensors of a facility, in-
dependently of the location, and to perform a remote diagnostic.
IO-Link uses an unshielded standard three or four-wire sensor cable. Cables between the IO-
Link master and a device can reach a length of up to 20 meters. Usually, M12 A-coded, unshiel-
ded standard automation cables are used.
Most of the IO-Link devices use a Class A IO-Link port. Output devices with a Class B IO-Link
port are also available. The port type of the master and/or the IO-Link device, i. e. Class A or
Class B, must be determined.
IO-Link allows, besides the most simple diagnostic (cable break), far more complex diagnostics,
which come directly from the IO-Link device. IO-Link also offers the possibilities of a dynamic
change of the parameters in IO-Link devices.

4.1.1 General Information for the Connection
ATTENTION Destruction of the device
Before connecting or disconnecting the signal cable, always discon-
nect the power supply and secure it against switching on again.
NOTICE General safety instructions
Make sure that the whole plant remains switched off during the elec-
trical installation.
• Make sure that the operating voltage is switched on or off simultan-
eously for the device and the downstream device.
NOTICE Traction relief
Always mount all cables with traction relief.

NOTICE Use of pin 2
The IO-Link signal I/Q, which represents an optional and currently not
realized digital In/Output, is applied on pin 2, in compliance with the
standard. The use of this pin is currently not planned (marked ac-
cordingly as Reserved in the table).
IO-Link masters offer the possibility to connect the I/Q signal. When
using a 4 on 4-pin (5 on 5-pin), A-coded IO-Link cable, the proper
connection is ensured directly by the orientation of the connector. For
devices with cable outlet, the white cable (I/Q signal) must be con-
nected to the corresponding contact of the IO-Link master.
4.1.3 Network Topology
IO-Link uses a point-to-point communication.
132121483
IO-Link provides for the use of an unshielded line. If the encoder is operated with an unshielded
line, its interference immunity falls in Criterion B and its radiation in Class A according to
61326-1.
If the application requires a higher EMC protection, it is possible to use a shielded cable. If the
encoder is operated with a shielded cable, its interference immunity falls in Criterion A and its
radiation in Class B according to 61326-1.
For currents lower than 200 mA in the IO-Link device, a cable with wire cross-section 0.35 mm²
can be used. The maximum line length can be 20 m.
The illustration below shows an example of a topology:

<= Acceleration upper limit
The closest to the signed min/
max 32-bit integer and the 32-bit
floating-point value without
loss of accuracy.
The unit changes with the accel-
eration format. The limit values
must then be converted accord-
ingly, e.g. 2 counts/ms2 =
2,000,000 counts/s2.
5.2.3 Changing the Parameters
Parameters can be modified by means of individual parameterizing or block parameterizing.
The parameters are automatically saved in a non-volatile way in the device.
Individual parameterizing
Modify, mark and write an individual parameter.
