FUNCTION_BLOCK AbbLConC2 IMPLEMENTS IAbbLConC2

State machine for level controlled continuous behaviour function blocks Limitations: * B_CyclicAction is called even if A_StartAction has set xError:=TRUE -> Make sure to check for xError=FALSE in B_CyclicAction!

InOut:

Scope	Name	Type	Initial	Comment
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.
Output	Busy	BOOL	FALSE	Operation is running (while output Error is FALSE)
	Error	BOOL	FALSE	Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.
