Configure Channel Output
State in Fault Mode

Short Circuit Protection

You can configure individual output channels to specific states when a connection fault
occurs, that is, the connection between the controller and the IO-Link master module breaks.

Output Behavior Immediately After a Connection Fault

When the connection between a controller and module breaks, the output can behave in the
following ways, depending on how the Output State in Fault Mode parameter is configured:
• Turn off - Default
• Turn on
• Hold its last state
The output remains at that state value until the following occurs:
• The connection to the controller is re-established.
• The duration expired, which is based on the value that is defined in the "Fault Mode
State Duration".

Fault Mode State Duration After Connection Fault

For output behavior after a connection fault, you must define how long the output remains at
the specified value before it transitions to a Final Fault State.
You can configure the output to remain at the specific value for the following times:
• Forever
• 1 second
• 2 seconds
• 5 seconds
• 10 seconds
After the Fault State Duration time expires, the output transitions to the user-defined Final
Fault Mode State value.

Final Fault Mode State Value

The Final Fault Mode State value defines the value to which the output goes after the Fault
Mode State Duration time expires.
Output State Once Connection is Re-established
Once the connection between the controller and module is re-established, the output resumes
normal operation.
To configure the output states in Fault mode, see
Short circuit protection helps prevent damage that can result from driving a current from the
channel greater than the maximum current level that the channel can handle.
Figure 2 shows the short circuit conditions and protections that are provided on the different
ports.
