SICK MLG-2 Pro

8 IO-Link
The MLG-2 has an IO-Link interface.
8.1 Configuration via acyclic service data
The service data can be used to configure functions such as the alignment aid, teach-
in, pushbutton lock, beam blanking, or a change of operating mode. 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 Pro, IO-Link V1.01 (SICK part number 8017124)
•
MLG-2 Pro, IO-Link V1.1 (SICK part number 8017185)
8.2 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-2s 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. This is only valid in conjunction with V1.1.
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).
8.3 Output of process data from the MLG-2 Pro
Transmission data
•
Cycle time: 14 ms (applies to IO-Link V1.1)
•
Frame type: TYPE_2_V
•
Data volume (payload): 32 bytes
Data output
The MLG-2 Pro device variant has a configurable process data format. The IO-Link index
120 (dec) determines the format. The following options are possible:
•
Value 0 = Data output of the beam status in the run-length code
•
Value 1 = Data output of the binary beam status
•
Value 2 = User-defined, configurable data output
Data output of the beam status in the run-length code
Byte 0 Byte 1 Byte 2 … 31
Status of the
switching outputs
Bit 0 … 3: Q1 … Q4
Bit 3 … 7: reserved
System status Beam status in the run-length code
RLC1 … RLC15
