Configure IO-Link Process Data Output State When IO-Link Device is in Program Mode or Inhibited
You can configure the IO-Link process data output to specific states when the IO-Link
device is in Program mode or when the device is inhibited.
When the controller switches from Run mode to Program mode, the output can behave in the
following ways, depending on how you configure the Process Data Output State in Program
Mode parameter (
C.ProgMode
tag):- Device DecidesThe 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 OutputThe 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 ZerosThe process data output remains enabled and all zeros output process data is sent to the device.
When the IO-Link device is inhibited, the process data output behavior follows the
Process Data Output State in Program Mode configuration.
To configure the IO-Link process data output state, see Fault/Program Action View.
