Behavior of the function block

The function block checks the axis interface that has been passed to it if TRUE is asserted at Enable. The current error code is reported as AxisErrorID. If Enable is FALSE, the function block cancels all pending output signals.

	This function block requires no time and no preconditions for executing its tasks. The outputs Error and Busy will never assume the value TRUE and only exist for compatibility reasons.
