Description: The part of the point index that refers to an EventSensor.

The point index is a string of 3 numbers separated by periods. It contains all the information necessary for getting a piece of data off an event sensor; namely, which EventSensor, point class, and which-sensor-of-that-class (a.k.a. point).

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 esIndexES=2 will now refer to that particular EventSensor.
