FUNCTION_BLOCK AbbETrig2 IMPLEMENTS IAbbETrig2

State machine for edge triggered function blocks Limitation: 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	Execute	BOOL	FALSE	A rising edge starts the operation, the output Busy goes to TRUE. In the first cycle all other inputs are read and stored, afterwards they are ignored. A falling edge does not stop the operation. After Done = TRUE or Error = TRUE and Execute = FALSE all outputs will be reset.
Output	Done	BOOL	FALSE	Operation is completed without error (while outputs Busy and Error are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)
	Error	BOOL	FALSE	Operation is stopped with error (while outputs Busy and Done are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE. The output ErrorID gives more details about the error.
