NOTE
After the upload of the parameter data, the vendor ID and device ID of the connected IO-
Link device are also still saved until the data records are deleted.
When the connected IO-Link device is started, a validation takes place. Thus, only an IO-
Link device of the same type can be used for the data management. If an IO-Link device of
a different type is to be used, the contents of the parameter server must be deleted.
Data storage is supported only by IO-Link devices with IO-Link Revision 1.1. The upload
flag on the IO-Link device is needed to overwrite already saved data in the parameter server
with new parameter data of the same IO-Link device.
To enable the upload flag of an IO-Link device the data value 5 must be entered in Index 2,
Subindex 0.

Configuration via explicit messages
Fault State
The Fault State function can be used to specify which value the digital in-/outputs assume when the bus connection is
lost. This always affects pin 2. It affects pin 4 if it is configured as a digital I/O line.
Standard services 14 (Get Attribute Single) and 16 (Set Attribute Single) are used for the fault state. Values can be read
(Get Attribute Single) and written (Set Attribute Single).
Attribute 6 enables or disables the Fault State function:
Class
Instance
Attribute
Value
9
1
6
0: Fault State disabled
1: Fault State enabled
When the Fault State function is enabled Attribute 5 is used to specify how the line should respond in case of a bus inter-
ruption. It can either enable the output (Output on) or hold the last set value (Hold last state).
Class
Instance
Attribute
Value
9
1
5
0: Output on
1: Hold last state
If the
Fault State
function is not enabled, IOs are high-impedance if the bus connection fails, and behave then like an
input.
NOTE
The fault state settings are stored only temporarily in the
SMARTCAMERA
. They are de-
leted after a restart.
To ensure a long-term fault state configuration, the configuration has to be programmed via
the host system so that the settings are transferred to the module again whenever the sys-
tem is restarted.
