All about IO-Link
IO-Link Brings Intelligence to Simple Devices IO-Link is not an industrial network, but rather a
simple protocol that adds communication capabilities to devices connected to existing industrial networks. A point-to-point connection
Former named by Siemens: IQ sense IO-Link uses the existing 24 VDC point-to-point
wiring between field devices and I/O channels to transmit additional data via a UART-based pulse modulation over distances of up to 15 meters.
Driven mainly by sensor companies. Own field bus organisation:

IO-Link Beneftis
Peer-to-peer connection no fieldbus technology
Standard sensor / actuator cable Serial communication
making sensors communicative
Mixed operation possible Use of intelligence given in the sensor /
actuator Reducing the variety of interfaces by means of
standardisation Convenient parameter setting and storage Central diagnosis of the whole plant

Technical dataTechnical characteristics Standard I/O connection techniques, unscreened,
20 m cable length Cyclical, deterministic process data typ. 2 ms
with parallel service data transmission Integrated, differentiated diagnostic messages Communication by means of 24 V pulse
modulation, standard UART protocol
-
TV-NP/VUK
Customer benefitsCustomer benefits Reducing the projection and installation costs by
means of a standardised interface Reducing the commissioning and set-up times by
means of transparent parameter storage Reducing machine downtimes by means of
differentiated diagnosis Sound investment due to the compatibility with the
installed base and field bus neutrality
Point to ponder:Today unknown costs for IO-Link master and therefore overall system costs.

configuration is done in a Hardware Configurator including module/device parameter setting and start up parameterization. All relevant information about the device is captured in a generic station description file (GSD)
Software tools for network configuration Siemens: SIMATIC Step 7 Hilscher: Sycon ConfiguratorParameterization Usually parameters are downloaded to the filed
device during the start-up routine. Some field devices support the function start with local parameters. Alternatively parameters can be set via DPV1 with the PLC program.

What is Ethernet?
With the term Ethernet many elements of a typical office network structure are referenced
The official standard of ethernet defined by the IEEE (Institute of Electrical and Electronics Engineers) is IEEE 802.3 CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
Ethernet is a definition of the group physical LAN (Local Area Network) IEEE 802
Ethernet is a group of defined protocols on defined hardware interfaces
Ethernet is an electronic medium for software based transportation, communication and application protocols

Ethernet in the ISO/OSI network model
Ethernet is defined in the levels 1 and 2 of the ISO/OSI network model
The upper level of the OSI model can also work with other network access definitions then ethernet
Ethernet describes cables, communication media and hardware interfaces in level 1. Data access via CSMA/CD and the Ethernet Frame are described in level 2
Ethernet is common in office and home networks. PCs, printers and servers use typically ethernet

Ethernet address
Every ethernet device has a worldwideunique ethernet address (also called MAC address or MAC-ID)
In the levels of the network access of ethernet, devices just communicate with each other via the MAC-IDs
Via ethernet the devices of a network can communicate with each other.To communicate with other networks one device (e.g. network router) has to use other network access medias (Telephone network) and protocols of the upper level

one or more networks, is handled at level 3 and 4 of the network model witch is referencedby the term TCP/IP
Level 5 and 6 (Session management) are not used in the ethernet environment

TCP and UDP The transportation protocols
TCP Transfer Control Protocol TCP creates a virtual connection. The data is
divided into packets. This packets are sent to the receiver. If packets get lost the addressor sends them again.Typically used for file transfer.
UDP User Datagram Protocol UDP sends packets without acknowledgments to
the receiver. It is used for fast applications.

Industrial Ethernet hardware components
Typical components in ethernet networks are hubs and switches with RJ45 connectors
The industrial environment defines higher conditions in the field:- High protection rates, e.g. IP65/67- Temperature- Vibration- Reliability,
Typical office components cannot fulfill such conditions
New definitions for special business orientations define special components
The prices of industrial ethernet components are much more expensive

Industrial Ethernet vs. fieldbus competition or co-existence?Target situation Current situation
One industrial Ethernet protocol > 5 relevant industrial Ethernet protocols
Use of hardware from PCs and consumer products results in uniform,
standardised products.
Didnt happen: necessity for individualised hardware and designs for
each system, few usable electronic components from PC technology
Reduced hook-up costs per device thanks to large quantities and
inexpensive hardware. Vision: industrial Ethernet in the individual
sensor/actuator
Mission botched: price increase for hook-up costs per node due to
quantity splitting, high performance electronics and individual design
Utilisation of IT functions in the front-end automation device provides a
transparent link to master systems, as well as increased data
communication.
Not previously utilised: IT functions are usually only used as of the
control level; few projects with IT at the field level.
High performance communication with regard to data width, speed and
synchronisation allows for the integration of motion control applications
into an network with other field devices.
Mission accomplished: variants with fast, synchronous data
communication in co-existence with standard communications on a single
bus.

In Europe, less than 10% of shipped devices are with PA or FF, 90% are 4..20mA/HART
Price difference 4..20mA/HART to Fieldbus Device: typically 50 to 100 EUR
