SIO mode parameters
In addition to data exchange in IO-Link mode, the device can also switch in SIO mode
(standard I/O).
To do so, configure SIO mode in parameter 0x41. In SIO mode, the device offers four
evaluation conditions each (subindex 0x01 or 0x06) for both the Q1 or Q2 digital
outputs.
Display behavior in the respective mode:
•
When using the “Transponder Presence” condition, the digital output is activated
as soon as a tag is located in the field (0x00).
•
When using the “Compare Data” condition, the device compares the data read
from the transponder to the reference data. To do so, the device compares the
data of the first four bytes of a memory block. Define the reference data for
the device in subindex 0x03. The data structure of the device is structured in
hexadecimal format and you have to ensure the data is input correctly.
Example: filter definition for a block
°
Data in transponder: 0x01 0x02 0x03 0x04
°
Input for filtering: 0x04 0x03 0x02 0x01
•
The 0x02 and 0x03 indices make it possible to use the alarm function of the
device in SIO mode. Description of the function
Configure the polarity for the events in SIO mode in subindex 3. The data retention time
specifies how long the device keeps the level of the output after the SIO condition is no
longer met.
C/Q1 SIO mode works on pin 4 of the M12 plug connector, in classic SIO mode in
accordance with IEC61131-9. C/Q2 mode uses pin 2 as a digital output.

In order to use pin 2 as a digital input in the available IO-Link master, check the
configuration options of your IO-Link master.
