ChannelStatus01 to ChannelStatus04
This register is used to show the current status of the IO-Link channel.
Data type

Status
0
Channel inactive
Disabled
1
Use as digital SIO output
2
Use as digital SIO input
SIO mode
3
Startup of IO-Link device, PREOPERATIONAL mode
Communication is running but
no process data is exchanged.
However, acyclic access is al-
so possible.
4
Operation, OPERATE mode
5
Operation, parameter server data OK
Communication is running
6
Parameter server: Upload active
7
Parameter server: Download active
8
Parameter server: Deleting active
9
IODD parameters are written
Communication is running and
process data is being returned.
10 to 19

21
General error in the parameter server. For example:
•
Parameter server not supported
•
Error accessing an object that is managed by the para-
meter server
•
Internal error
22
Parameter server locked by IO-Link device
23
Parameter server empty:
Tried to load data to the IO-Link device even though no data is
saved in EEPROM
24
New serial number recognized:
The user must decide via the DsControl register what has to be
done (Upload – Download – Restore default values)
25
Parameter server not compatible (new DeviceID or new Ven-
dorID recognized):
The data in EEPROM is not suitable for the connected IO-Link
device. The user must decide via the DsControl register whether
an upload should be carried out.
26
Upload request received.
The user must decide via the DsControl register what must be
done (Upload – Download – Restore default values).
27
The parameter checksum of the IO-Link device has changed:
The user must decide via the DsControl register what must be
done (Upload – Download – Restore default values).
28
Error when sending the SAVE command
Communication is running.
However, an error has oc-
curred on the parameter serv-
er.
Parameter server errors can be
acknowledged via the DsCon-

However, process data was
marked as invalid by the de-
vice.

42
The DeviceID and VendorID of the connected IO-Link device do
not match the predefined IDs.
43

44
Timestamp error
The IO-Link device does not support IO-Link timestamps.
Communication is running but
no process data is exchanged.
However, acyclic access is al-
so possible.

Error starting up the device
No communication

4.26.5.9.5.6 FrameCount
Name:
FrameCount01 to FrameCount04
Received IO-Link frames are counted in this register. Unlike the sync bits, the FrameCount register ensures that
all frames are actually recognized. This is the case even if X2X cycles are lost or if the IO-Link cycle is faster than
the X2X cycle.
