SICK MLG-2 Prime

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, pushbutt
on 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 par
ameter lists for all readable and writable data are available as separate docu‐
ments:
•
MLG-2 Prime, IO-Link V1.01 (SICK part number 8017123)
•
MLG-2 Prime, IO-Link V1.1 (SICK part number 8017184)
8.2 Data storage (IO-Link)
All light grid parameters can be saved in the control system via an IO-Link master using
t
he d
ata 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 de
vice 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 par
t number 1064290) can provide this functionality (see www.sick.de).
8.3 Output of process data from the MLG-2 Prime
Transmission data
•
Cy
cle time: 6 ms (applies to IO-Link V1.1)
•
Frame type: TYPE_2_V
•
Data volume (payload): 6 bytes
Data output
The MLG-2 Prime has a fixed process data format:
Table 21: Data output of the MLG-2 Prime
Byte 0 Byte 1 Bytes 2 and 3 Bytes 4 and 5
Status of the
sw
itching outputs
Bit 0 … 2: Q1 … Q3
Bit 3 … 7: reserved
System status Output function 1
(de
fault = NBB)
Output function 2
(default = LBB)
On an MLG-2 Prime with analog outputs, the configuration of output functions 1 and 2
det
ermines the content of the process data, as well as the applications of analog out‐
puts 1 and 2.
