9.2.17 IO-Link devices: Accessing parameters
The ifm IoT Core supports access to the parameters of connected IO-Link devices via the IT network
using ISDU (Index Service Data Unit). Each parameter can be addressed via its ISDU index and ISDU
subindex (Ò IODD of the IO-Link device). If access to the IO-Link device is faulty, the ISDU error code
will also be output in the response (Ò IODD of the IO-Link device).
Substructure: iolinkmaster/port[x]/iolinkdevice (x: 1…8)
Applicable services:
Name Description
../iolreadacyclic Read a parameter of an IO-Link device (acyclic)
../iolwriteacyclic Write a parameter of an IO-Link device (acyclic)
When using the validation level "Type compatible V1.1 Device with Backup + Restore":
After changing a parameter via ISDU write access, the user must end the parameter setting process
with the "ParamDownloadStore" system command and activate the data storage mechanism on the
IO-Link device.
u Set the SystemCommand object (ISDU index: 0x0002) to the value 0x05 (command
"ParamDownloadStore") via acyclic ISDU write access.
w The parameter setting process is finished.
