Configure IO-Link Process Data Output State in Fault Mode

You can configure the IO-Link process data output to specific states when the IO-Link device connection is in Fault mode.

When the IO-Link device connection is faulted, the process data output can behave in the following ways, depending on how you configure the Process Data Output State in Fault Mode parameter (

C.FaultMode

tag):

Device Decides
The IO-Link master module disables the process data output and the device determines the actual state of the output.
WARNING: The device vendor determines the behavior of a device that is set for the “Device Decides” output state. You must verify proper operation of the device.
Hold Process Data Output
The process data output remains enabled and the last received output process data is sent to the device.
WARNING: For the “Hold Process Data Output” output state, the device output may change if the device configuration changes.
All Zeros
The process data output remains enabled and all zeros output process data is sent to the device.

When the IO-Link device connection is faulted when the connection is in Program Mode, if the value of the device

C.ProgramtoFaultEn

tag is set to 1, the output process data behavior follows the device

C.FaultMode

tag setting; If set to 0, the output process data output behavior follows the device

C.ProgMode

tag setting.

To configure the IO-Link process data output state, see Fault/Program Action View.
