Replacing an IO-Link device
6.5.1
Introduction
To replace 3RA27 modules, the devices must be isolated from communication and disconnected
from the power supply. The complete group of load feeders becomes inactive. After removal of
the connections between the load feeders, the applicable module can then be replaced. After
the connections have been restored and communication has been resumed, the
parameterization can be restored according to the respective IO‑Link communication
specification:
• IO‑Link communication specification V1.0: concerning the LIOLink_Device function block.
• IO‑Link communication specification V1.1: via automatic parameterization under the
ET 200SP

Replacing an IO-Link device according to the IO-Link communication
specification V1.0
6.5.2.1
Procedure
Parameter data and configuration data specially optimized by the user for a specific application
are stored in an IO‑Link‑Device. This data deviates in many cases from the default values stored
in the IO‑Link‑Device.
In the event of replacement of an IO-Link‑Device (referred to below as a "module"), the
optimized data must be transferred to the new module because the parameters are stored
only in the IO-Link device itself.
Data can be transferred via two channels:
• Module replacement with PG/PC
• Module replacement without PG/PC
6.5.2.2
Procedure with PG/PC
In the event of a replacement, a PG/PC is available with the SIMATIC project of the plant.
With the data stored in the SIMATIC project, and the S7-PCT port configuration tool, you
transfer the parameters belonging to the replaced IO‑Link‑Device to the new IO‑Link‑Device.
