Y_YA_Action

This function block is only for demonstration purposes. It is applied in the Enable_F_Template, Enable_ST_Template, Execute_FB_Template, and Execute_ST_Template function blocks to show how the inputs and outputs of nested functions can be interlocked to apply the PLCopen standards for I/O behavior.

Parameters

*	Parameter	Data Type	Description	Default
VAR_INPUT
B	Execute	BOOL	Upon the rising edge of the Execute input, all other inputs are read and the function block becomes operational. If an input needs to be modified, the value will have to be changed and the Execute input will have to be re-triggered.	FALSE
VAR_OUTPUT
B	Done	BOOL	The Done output is set to TRUE when the commanded action has completed successfully. If another function block takes control before the action is completed, the Done output will never become TRUE. This output is reset when Execute becomes FALSE.
B	Busy	BOOL	For function blocks with Execute input, the Busy output is set to TRUE upon the rising edge of the Execute, and set to FALSE when Done, CommandAborted or Error outputs becomes TRUE. In the case of a function block with an Enable input, Busy indicates that the function block is operating, but may not be ready to provide valid outputs.
B	CommandAborted	BOOL	The CommandAborted output is set to TRUE if the operation performed by the instance of the function block is aborted by another command.
B	Error	BOOL	The Error output is set to TRUE if an error has occurred during the operation of the function block. The output is cleared when the Execute or Enable input becomes FALSE.
E	ErrorID	UINT	The ErrorID output provides the identifier of the error when there is an active error in the function block execution. The output is cleared when the Execute or Enable input becomes FALSE.
