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…4)
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.
w The data storage mechanism on IO-Link device will be activated.
w The IO-Link device synchronises changed parameter values with data storage of the IO-Link
master.
9.2.17.1 Example: Reading a parameter value of an IO-Link device
Task: Reading the serial number of the ifm temperature sensor TN2531 at port 2.
Solution: Read the serial number with the iolreadacyclic service from the IO-Link device (index:
21, subindex: 0)
