### Function description

#### General

This function block is used to generate signals after each CPU restart.\
The CPU restart can be triggered via the simulation input **xTest** (= TRUE) independently of an actual CPU restart.\
\
The output *xQ1* changes after each CPU restart with a time delay **TimeQ1** from the FALSE state permanently into the TRUE state.\
At pulse output 1 *xQ1p* a single pulse with the pulse length **TimeQ1Puls** is generated.\
\
The output *xQ2* changes after each CPU restart with a time delay **TimeQ2** from the FALSE state permanently into the TRUE state.\
At pulse output 2 *xQ2p* a single pulse with the pulse length **TimeQ2Puls** is generated.
