12.4 Behavior of the device in the event of a fault
The device displays warnings and faults via IO-Link. All the device warnings and faults are
for information purposes only and do not have a safety function. The errors diagnosed by
the device are displayed via IO-Link in accordance with NE107. Depending on the
diagnostic message, the device behaves as per a warning or fault condition. A distinction
must be made between the following types of error here:
• Warning:
– The device continues measuring if this type of error occurs. The output signal is not
affected (exception: simulation is active).
– The switch output remains in the state defined by the switch points.
• Fault:
– The device does
not
continue measuring if this type of error occurs. The output signal
assumes its fault state (switch outputs de-energized).
– The fault state is displayed via IO-Link.
– The switch output changes to the "open" state.
