the enable to behave as an Et trip input. When the input becomes inactive an Et trip is initiated. This does not affect Pr 10.32 (Et trip parameter),
therefore an Et trip can be initiated in this mode either by making the enable inactive or setting Pr 10.32 to one.
This word is used to determine the status of the digital I/O by reading one parameter. The bits in this word reflect the state of Pr 8.01 to Pr 8.09.
