According to the requirements set out in the PI document PROFIsafe - Test Specification Order No.: 2.242, chapter 6 Manufacturer
obligations, the PROFIsafe device is designed and has been verified also to fulfill the following properties:

Transfer failsafe values at the first 3 PROFIsafe telegram cycles to the PROFIsafe Device physical output signal independently of the
l
user data from the F-Host. This rule is described in IEC 61784-3-3 ed.3, Table 10: Transition T27: statement if ok_nr_cycles <4, then
use FVo, FV_activated =1.
The reception of zero-telegrams is ignored. If a zero-telegram (all values are 0) is received, the PROFIsafe watchdog continues to run
l
to make sure possible timeouts can be recognized. This rule is described in IEC 61784-3-3 ed.3, Table 10: statement ignore safety
