SICK OLM100 User Manual

The application-specific P
lausibility testSAPP-FB function block checks whether the posi‐
tion data from the sensor is plausible.
The process control uses test signals to check whether the standstill and direction condi‐
tions read (from the SSI position data) are plausible.
In addition, the sensors generate their own standstill signal, which they transmit to the
Flexi Soft safety controller via the digital outputs (sensor ID signal). These standstill signals
are also used for the plausibility check.

7.5.4.2 Sensor2 test SAPP-FB function block
The application-specific S
ensor2 test SAPP-FB function block detects systematic faults
that occur on both sensors at the same time. In the case of this kind of fault, the posi‐
tion data can freeze the two sensors and output a static position. This would be inter‐
preted as a standstill.
Test procedure:
After a relatively long inactive phase, Flexi Soft sends a query signal to sensor 2 as a
test. The sensor then performs an internal test. Flexi Soft can use the data read at the
SSI interface to check that the test has been performed successfully and that the test
results coincide with the expectations.
