Use the ActivePoint Behavior option to determine how the transitions in Active Point values are interpreted. There are three possible ways the start and end of a PISubBatch can be determined: Pulse, Step, and Include zeroth state (Continuous). The default value is Step.
-
Step: Step type behavior of Active Point will cause a PISubBatch to start if there is a non-zero state and a PIUnitBatch is not currently running. If a PIUnitBatch is currently running when the non-zero state occurs, the PIUnitBatch will stop and a new PISubBatch will be started.
-
Pulse: Pulse type behavior of Active Point means that transitions from zeroth state (or value 0 for integer type or the string that indicates zeroth state) to any other state to start a PISubBatch and transition from any other state to zeroth state to end an existing PISubBatch. All other transitions are ignored.Zeroth state is what you assign a value to - mostly strings, either a digital state or integer point are used. For example, 0,1,2.
-
Continuous: Continuous type behavior of Active Point means that all transitions result in ending the current PISubBatch and starting a new PISubBatch. This option is available only when Step is selected.
-
Strings Indicating ZerothState: For string type active points, if Step or Pulse option is selected, the string or strings indicating the zeroth state must also be specified. These strings are case-sensitive and they should be separated by a comma. For example if the strings Inactive,Off and an empty string indicate a zeroth state, then this parameter should be Inactive, ,Off. The space between the two commas is interpreted as an empty string. Double quotes are not required. If this string is not specified, then a Pulse or Step for a string type active point is equivalent to a Continuous type.
