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

Name	Type	Comment	Kind
bInitRetains	BOOL	if TRUE, the retain variables are initialized (warm start / cold start)	input
bInCopyCode	BOOL	if TRUE, the instance afterwards gets moved into the copy code (online change)	input
set	ISetHelper	the set which this executor will dispatch	input
