D301171 - IO-Link master 1108 4-6
Configuration of the IOLMM (IO-Link master module)
Slot 1 of the modular slave contains the IO-Link master module (IOLMM). The IOLMM serves
as gateway between IO-Link and PROFIBUS-DP. It handles the IO-Link data of the IO-Link
ports for further processing on PROFIBUS.
Parameterization of the IOLMM
The parameters of the IO-Link master module (slot 1) control the communication of the
complete SDPX-IOL4-0001 including all connected devices.
The parameters of slot 1 (IOLMM) have to be set according to the application, see also
Chapter 3 , ”Parameterization” , page 3-19 .
Configuration of the IO-Link ports
The 4 ports of the IO-Link master (slot 2 to slot 5) can be operated either in IO-Link mode or
in SIO mode (see also
”GSD-file” , page 3-15 ).
The determining factor for the function mode of the ports is their configuration:
General
„
IO-Link mode:
If the port is to be used in the IO-Link mode, a sensor with a process data width > 0 has
to be selected from the hardware catalog.
IO-Link sensors from TURCK [TURCK … (IOL mode)] are described in the GSD-file of the
IO-Link master and can be comfortably parameterized via GSD-parameters.
Sensors from 3rd-party-manufacturers are represented as generic IO-Link devices with a
maximum number of 32 byte input- and/or output data
Figure 17: ”Parameterization via
GSD” .
Note
Please be sure that the parameter ”GSD parametrization” is set to active. Otherwise
the parameterization via GSD done in the following in the hardware configurator will
be ignored.

Note
The selected generic device has to be a device with a process data width
≥
the pro-
cess data width of the connected sensor.
