FB_init

Short summary​

The constructor FB_init is needed to create an unique hash code. The hash code is a pseudo random number create with a xorshift algorithm. It can be overwritten on derivations, because it will be called implicit, SUPER^.FB_init() is not required. For more information check: Behavoir with derived function blocks

  • Return type: BOOL

Parameters​
