Cycle time of the safety project

The execution time of the TwinSAFE logic can be read from the CoE objects listed below. To determine the
cycle time, it has to be multiplied with 1.25, because this is the factor used internally for generating a delay
time before the next cycle.

Resetting the values
The max. and min. values can be reset by writing a value to the CoE object 0x1C32:08.

Diagnosis History

The diagnostic history of the TwinSAFE devices that support this function is implemented in accordance with
the ETG guideline ETG.1020 Chapter 13 "Diagnosis Handling". The diagnostic messages are saved by the
TwinSAFE device in a dedicated CoE object under 0x10F3 and can be read out by the application or by
TwinCAT.
Both the control entries and the history itself can be found in the CoE object 0x10F3. The entry Newest
Message (0x10F3:02) contains the subindex of 0x10F3, which contains the latest diagnostic message, e.g.
0x06 for diagnostic message 1.
