Drift/difference mode

If two sensors are connected and the measured values differ by a specified value, a status
signal is generated as a diagnostic event. The drift/difference monitoring function can be
used to verify the correctness of the measured values and for mutual monitoring of the
connected sensors. Drift/difference monitoring is enabled with the Drift/difference mode
parameter. A distinction is made between two specific modes. If the In band option is
selected (ISV1-SV2I < drift/difference set point), a status message is issued if the value
drops below the set point, or if the value exceeds the set point if the Out band (drift)
option is selected (ISV1-SV2I > drift/difference set point).
Procedure for configuring the drift/difference mode
2. For drift/difference monitoring, select Out band for drift detection and In band for difference monitoring.
3. Set the set point for drift/difference monitoring to the desired value.
