Start-up: IO-Link-Device with IO-Link V1.1
The data storage of the master should be cleared before a device with a different device type is con-
nected to an IO-Link port which has already been used before.
Start-up
Set the "data storage mode" to "deactivated,clear".
Download the parameters into the device.
Re-activate the data storage if required.
Download the parameters into the device.
Connect the IO-Link V1.1 device.
LED „IOL“ = GREEN (for the respective port), IO-Link communication is active

Data storage
error
IO-Link device in accordance
with IO-Link V1.0 connected.
IO-Link devices in accordance
with IO-Link specification V1.0
do not support data storage
Deactivate the data storage.
To do so, set parameter
"
Data storage mode (Seite 21)
" to
"deactivated, clear".
The data storage buffer con-
tains data of another device.
Clear the data storage buffer of the
master.
To do so, set the parameter "
Data stor-
age mode (Seite 21)
" to "deactivated,
clear” and re-activate the data storage if
necessary.
Wrong or miss-
ing device
The connected device does not
match the configured one
(wrong vendor-ID, device-ID
etc.).
Change the parameterization of the IO-
Link port at the master.
Correct the vendor-ID, device-ID, etc.
The parameterization can be done by
teaching the master via IOL_CALL using
the port function
Subindex 67: Teach
Mode (Seite 43)
or via a manual port
parameterization.
Process input
data invalid
Certain IO-Link devices send a
"process input data invalid"-
diagnosis if the process value
cannot be measured.
Deactivate the sending of the "process
input data invalid"-diagnosis for the
respective port.
To do so, set parameter
"
Process input data invalid (Seite 22)
"
to "no diagnostic generated".
