Channel for Unsolicited Response
Only channels already configured for DNP3 protocol appear in the Channel for
Unsolicited Response dropdown menu. Any and all Unsolicited Responses are
transmitted via this selected channel.
Restore Events After Power Cycle
When the selection is Disabled (Unchecked), DNP3 events which are generated
before a power cycle are flushed after a power cycle. When the option is
Enabled (Checked), all DNP3 events are restored after a power cycle.
Valid selections are Enabled (Checked) and Disabled (Unchecked), with
disabled as default value.
Unsolicited Responses On Start Up
Valid selections are Enabled (Checked) and Disabled (Unchecked). Default
value is Disabled (Unchecked).
When the selection is Disabled (Unchecked), the controller does not send any
enabled Unsolicited Responses after a restart until it has received a
FC_ENABLE_UNSOLICITED (20) command from the DNP3 Master.
When the selection is Enabled (Checked), the controller sends any enabled
Unsolicited Responses after a restart to the DNP3 Master unconditionally.
Unsolicited Responses For Class1
Valid selections are Enabled (Checked) and Disabled (Unchecked). Default
value is Disabled (Unchecked).
When the selection is Disabled (Unchecked), Unsolicited Response is disabled
for Class 1 events. To prevent overflowing of the event buffer, DNP3 Master
should poll for Class 1 events.
When the selection is Enabled (Checked), Unsolicited Response is enabled for
Class 1 events.
