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

Parameters

• 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
modeHandler	CNM_OpModeHandlingInterfaces.IOpModeHandler	operation mode handler for the station	input
