Use the fields in the States section of the Digital Point tab to define state-related information for the point, such as the handling of state-related alarms.
Most of the fields within the States section are common to many digital points.
The Number of Bits, defined toward the top of the Form (see Common Point Properties), determines the number of state fields that are available for use. If the data type is Boolean (see List of OPC Data Types), there are only two states, state 0 is 'FALSE' and state 1 is 'TRUE'.
For further information on configuring state fields, see Define the Point States for a Digital Point.
For information on Persistence Type and Persistence Duration, see Use Persistence to Stop Fleeting Changes in Value from Changing a Point State.
