Menu / Parameter Value range Description
Diagnostics / Diagnosis Control / Sil Detection
SIL Detection On / Off
By switching on the detector the monitoring of safety-
relevant components is increased.
With the detector switched on an SFF value of 91.6 is
achieved for the FMEDA analysis (SIL2).
With the detector switched off an SFF value of 85.5 is
achieved for the FMEDA analysis (SIL1).
This is valid for all devices with HART protocol.

The “fingerprint” database integrated in the transmitter allows you to compare the values at the
time of factory calibration or commissioning with the currently recorded values.
As a result, changes of the measuring system can be detected early, and the appropriate
measures can be taken.
