Setting or clearing a Virtual Input will always succeed, however an operate of the Reset, Open Breaker, Close Breaker or
Breaker Control points may fail (even if the command is accepted) due to other inputs or conditions (e.g., blocks) existing at
the time. To verify the success or failure of an operate of these points it is necessary that the associated Binary Input(s) be
examined after the control attempt is performed.
When using object 10 to read the status of a Binary Output, a read of points 0 through 2 and 23 will always return zero. For
other points, the current state of the corresponding Virtual Input will be returned.
c) ANALOG INPUT / ANALOG INPUT CHANGE
In the following table, the entry in the “Format” column indicates that the format of the associated data point can be deter-
mined by looking up the entry in the Memory Map Data Formats table. For example, an “F1” format is described in that
table as a (16-bit) unsigned value without any decimal places. Therefore, the value read should be interpreted in this man-
ner.
