IO-Link is a non-proprietary internationally standardized communication technology
which makes it possible to communicate with sensors and actuators in industrial
environments (IEC 61131-9).
The IO-Link devices communicate with the superior control systems using an IO-Link
master.
The IO-Link devices (slaves) are connected to the master in a serial, bidirectional
point-to-point connection via an IO-Link interface (port). This arrangement does not
represent a fieldbus. IO-Link masters are available in different variants and usually
consist of decentralized, superior fieldbus gateways or input cards for the backplane
bus of the control used.
To make it possible for an IO-Link sensor to communicate with the control, the IO-Link
master and the respective IO-Link sensor must be integrated in the hardware configura‐
tion in the control manufacturer’s engineering tool.
To simplify the integration process, SICK provides sensor-specific device description
files (IODD = IO-Link Device Description) for IO-Link devices.
In addition to the process data, depending on the device, device data (parameters,
identification data, and diagnostic information) can be exchanged between the master
and the device. To use this function, the IO-Link master needs the sensor-specific
device description file (IODD).

Not all control system manufacturers support the use of IODDs. If third-party IO-Link
masters are used, the IO-Link sensor can be integrated directly during hardware config‐
uration by manually entering the relevant sensor parameters. To ensure that the IO-Link
sensor can be easily integrated into the control program, SICK also provides function
blocks for many control systems. These function blocks make it easier to read and write
the individual sensor parameters, for example, and provide support when it comes to
interpreting the process data supplied by the IO-Link sensor.

Service data (ISDU, parameter)
NOTE
The device contains a rewritable memory (flash memory) for storing configuration data
(parameters), such as Application Specific Tag, Location and Function Tag, RF field,
etc. It is strongly recommended to write configuration data permanently only during
commissioning. The device is not designed for permanent rewriting of configuration
data during operation. Temporary storage is not affected by this, e.g. data storage
(backup/restore) in the IO-Link master, which takes place in the volatile memory (RAM)
of the device.
8.3.1.1
RF Configuration
With RF configuration or the RSSI threshold, the detection range (working range) of the
device can be limited (reduced).
