The driver is configurable to perform the following action when a unit becomes active:
-
Send DNP3 link reset and then an integrity poll to the device. The polling sequence is reset to start from the time the unit became active.
-
Send DNP3 link reset and then read the RTU time. The polling sequence is not changed and continues as if nothing happened.
Note: The driver may perform additional DNP3 transactions depending on the states of the IIN bits. In particular if the IIN restart bit is set, the driver will perform and integrity poll. If any of the class 1, 2, or 3 event flags are set the driver will perform an event poll if the reset bit is not set.

Send DNP3 link reset and then a Class0 (Static) poll to the device. The polling sequence is reset to start from the time the unit became active.
