NOTES:
1. To support existing SCADA hardware that is not capable of 32-bit data reads, the upper and lower 16-bit portions of all
time and date values have been assigned to separate points. To read a date or time, it is necessary to read both the
upper and lower 16-bit portions, concatenate these two values to form a 32-bit value and interpret the result in the for-
mat associated with the point (i.e., F22 for time, F23 for date).
2. Points which have an assigned event class will generate an event object as a result of any change in the point’s value
unless otherwise noted.
3. An event object will be generated if the point’s value changes by a minimum of 2% of its previous value.
4. An event object will be generated if the system frequency changes by 0.04Hz or more.
5. There are two defined maps for Analog Output points. The map that is used is specified by the setting of the “DNP
Point Mapping” setpoint at Modbus address 10DB (hex). This setpoint may be set to a value of “Disabled” or
“Enabled”. When “Disabled”, only the preassigned Analog Output points are available beginning at point index 0.
