Configuration of the IO-Link system
Introduction
An IO-Link system is configured in several steps. In the first step, the master is integrated in
the automation system and configured. In the second step, the IO-Link devices are
configured.
Integration in the automation system
When using a SIMATIC S7 CPU, use the engineering tool STEP 7, V5.x or STEP 7 (TIA Portal) for
configuration.
The IO-Link system is represented by the IO‑Link master in the configuration of the
automation system or the fieldbus and integrated with STEP 7 or a GSD file.
The IO-Link master itself can be a field bus node (e.g. ET 200eco PN IO‑Link master) or a part
of the modular IO system that is connected to the field bus (e.g. ET 200SP IO-Link master). In
both cases, the number of ports, the address range and the module properties are described
in STEP 7 or in the GSD file.
Example configuration in STEP 7 (TIA Portal)
The figure below shows a PROFINET configuration with integrated PROFINET devices
ET 200SP and ET 200eco PN with IO-Link masters.
