TestExecuted output

Output for signaling the status of the sensor test.

Data type: BOOL

A TRUE signal at the TestExecuted output results that the sensor test has been completed without errors.

Note
The enable signal at the S_OSSD_Out output can be SAFETRUE even if there is no TRUE signal at TestExecuted.
The automatic test has to be performed with positive results for the safety-related sensor to function correctly.

Connection: Connect the TestExecuted output to a global I/O variable or via additional functions/function blocks in order to transmit the signal externally for diagnostic purposes (e.g., controlling a signal lamp).

Value Description

TRUE The automatic sensor test has been performed successfully.

Note
After a successful test, TestExecuted retains the TRUE status until a new sensor test is requested at the StartTest input.

FALSE The automatic sensor test

has not yet been performed.

or is currently in progress

or has been carried out with errors.

Refer to the warning below this table.

WARNING

Non-conformance to safety function requirements

Regularly check the safety-related sensor by periodically switching the StartTest input from FALSE to TRUE in accordance with the risk analysis.

Make certain that appropriate procedures and measures have been established to help avoid hazardous situations when applying TRUE to the StartTest input.
