TABLE NOTES:
1.Unless otherwise specified, an event object will be generated for a point if the current value of the point changes by an amount greater than or equal to two percent of its previous value.
2.An event object is created for the Frequency point if the frequency changes by 0.04 Hz or more from its previous value.
3.An event object is created for these points if the current value of a point is in any way changed from its previous value.
4.To support existing SCADA hardware that is not capable of
5.The data returned by a read of the User Map Value points is determined by the values programmed into the corresponding User Map Address registers (which are only accessible via Modbus). Refer to
6.The scale for
7.The scale for currents is determined by the value in point 47, which should not normally change
8.Each power quantity is available at two different points, with two different scale factors (kW and MW, for example). The user should select the unit which is clos- est to providing the resolution and range desired. If
9.Analog input values may be
10.Each neutral voltage quantity is available at two different points, with two dif- ferent scale factors (volts and tenths of a volt). The user should select the unit which is closest to providing the resolution and range desired. If
