2.6 IODD and Port Configuration Tool - S7-PCT
Device description IODD
An electronic device description, the IODD file (IO Device Description) is available for each
device. The IODD provides a wealth of information for system integration:
● Communication properties
● Device parameters with value range and default value
● Identification, process and diagnostic data
● Device data
● Text description
● Image of the device
● Manufacturer logo
The structure of the IODD is identical for all devices from all manufacturers. The structure of
the IODD is always represented in the identical manner by the IO-Link Configuration Tool of
the master manufacturer (for Siemens, S7-PCT). This ensures that the handling is the same
for all IO-Link devices regardless of the manufacturer.
Two different IODD versions are available for devices that support both V1.0 and V1.1
functionality.
IODDfinder
The IODDfinder is a cross-vendor, central IO-Link database.
This database provides you with the latest IODDs of the device manufacturers and offers an
information and download platform.
The IODDfinder is available on the Internet ( https://ioddfinder.io-link.com ).
IO-Link configuration tool
Configuration tools are required to configure the entire IO-Link system. The IO-Link
configuration tools of the master manufacturers are able to read IODDs.
The main tasks of the IO-Link configuration tool include:
● Assigning the devices to the ports of the master
● Address assignment of ports within the address area of the master
● Assigning parameters for the IO-Link device
Diagnostics can also be carried out on the connected devices.
This means the IO-Link configuration tool supports the transparent representation of the
IO-Link system down to field level.
Siemens provides S7-PCT for engineering of the IO-Link system.
