The Select Before Operate command causes the device to start a
timer. The following Operate command must be sent before the specified
timeout value expires.
2
The device requests time synchronization by bit 4 in the first octet
of the internal indication word being set to 1 when the time interval
specified by the Time Sync Period elapses. The master should
synchronize the time in the device by sending the Time and Date object
to clear this bit. The device does not send time synchronization requests
if the Time Sync Period is set to 0.
3
The total number of AI, BI and BC change event points may not
exceed 64. When you change the number of the change event
points in the device, all event setpoints are set to defaults (see
Configuring DNP Event Classes below).
