DIQ/S 281
ba77244d01
When an IQ sensor is connected to the system, the system checks whether an
inactive dataset is available for the sensor type.
If an inactive dataset for the sensor type is available, the inactive dataset is auto-
matically assigned to the newly connected sensor. The IQ sensor starts oper-
ating with the settings from the inactive dataset.
Examples:
 The sensor is reconnected after completion of some mainte-
nance- or repair work.
 The sensor is being replaced by another sensor of the same type.
The replacement sensor should at least have the software status
of the active IQ sensor.
This mechanism ensures that the IQ sensor retains its settings and links if it was
removed for maintenance or if the system was temporarily switched off.
