This number refers to an EventSensor; it has the same meaning as the esIndexES object (see above), except that this object is used only within the esTable branch. This object's allowable values are 1 through 16, and 200. 200 always refers to the EventSensor inside the unit. 1 through 16 refer to additional attached EventSensors. The number corresponding to an EventSensor is determined by the user at the initial configuration time. If there is an internal sensor in the unit, it will always be the first item in the Sensor Events setup menu. For example, if a new EventSensor is configured as the 2nd entry AFTER the internal EventSensor (if one exists) in the Sensor Events Setup Menu, then that EventSensor will be known from then on as EventSensor 2. All point indeces with esIndex=2 will now refer to that particular EventSensor.
