11 IO-Link
The MLG-2 has an IO-Link interface.
11.1 Configuration via acyclic service data
The service data can be used to configure functions such as the alignment aid, teach-
in, pushbutton lock and functions. It can also be used to read out the process or teach-
in quality, for example.
NOTE
The parameter lists for all readable and writable data are available as separate docu‐
ments:
•
MLG-2, IO-Link V1.1 (SICK part number 8024539)
11.2 Data storage (IO-Link)
All light grid parameters can be saved in the control system via an IO-Link master using
the data storage IO-Link function. If the device is replaced, these parameters can be
written to the new device, or they can be distributed to multiple MLG-2 units with the
same application.
NOTE
The device replacement via the IO-Link function data storage is only possible with an
MLG-2 with the same part number.
If the IO-Link master does not support data storage technology, the SICK memory stick
(SICK part number 1064290) can provide this functionality (see www.sick.de).
11.3 Output of process data from the MLG-2
Transmission data
•
Cycle time: 14 ms (applies to IO-Link V1.1)
•
Frame type: TYPE_2_V
•
Data volume (application data): 32 bytes
Data output
The MLG-2 device variant has a configurable process data format.
User-defined data output
Table 34: User-defined data output
Byte 0 and 1 Byte 2 and 3 … Byte 30 and 31
Output function 1 Output function 2 … Output function 16
You can configure the content of output functions 1 to 16 via IO-Link index 67dec. This
could, for example, be the position of edges, configured functions, status and quality
values.
