4.4.1 IO-Link mode
The devices must be connected to an IO-Link master for operation in IO-Link mode. If the port is
configured in IOL mode, bidirectional IO-Link communication is provided between the IO-Link
master and the device. For this the device is integrated in the controller level via an IO-Link
master. The communication parameters are exchanged first of all; the cyclic data exchange of
the process data (process data objects) then starts.
4.4.2 SIO mode (standard I/O mode)
In standard I/O mode no IO-Link communication takes place between the device and the mas-
ter. The device only transfers the switching state of its binary outputs and can also be run via a
fieldbus device or controller with digital PNP or NPN inputs. An IO-Link master is not required
for operation.
The device parameters can be set via IO-Link and then operated at the digital inputs with the
appropriate settings in SIO mode. Not all functions and properties of the device can be used in
SIO mode.
4.4.3 RSSI value output
The RSSI value denotes the signal strength of the response from the tag to the read/write head.
The RSSI value is not output as a physical value but as a value on a scale from 0…7. The RSSI
value does not have a linear characteristic in relation to the read/write distance.
An RSSI value can be set via IO-Link as a limit value (e.g. for alarm functions).
The RSSI value depends on the following factors:
n Distance between read/write head and tag: The shorter the distance between read/write
head and tag, the greater the RSSI value.
n Dimensions of the tag: The larger the tag, the greater the RSSI value.
n
Effect of metal: Metal has an effect on the electromagnetic field of the read/write head and
thus the RSSI value.
n
Tolerances: A tolerance of up to 30 % must be calculated for the achievable range of the
tags. The 30 % tolerance also applies to the RSSI value.
4.4.4 Password function
The password function enables the memory areas of the tags with the following chip types to
be protected from write or read access:
n
NXP ICODE SLIX2
n
EM4233SLIC
A password for the tags cannot be defined with the IO-Link read/write heads. The tags must be
provided with a password via the standard HF read/write head with a TBEN interface. Alternat-
ively, Turck offers preconfigured tags with a password on request.
