●
Buffer for class 1 / class 2 / class 3 events
Once the number of events of the specified class entered here is reached in the send
buffer (message memory) of the TIM, the relevant messages are sent to the DNP3
master station and the events are deleted from the send buffer.
Note that the maximum size of the send buffer of the TIM is divided among all connected
DNP3 master stations.
Ranges of values:
– TIM 3V-IE DNP3: 0 ... 65535
– TIM 4R-IE DNP3: 0 ... 200000
Default: 1
●
Delay time for class 1 / class 2 / class 3 events [s]
Specifies the maximum delay after which an event belonging to the specified class can
be sent to the partner after it has occurred if spontaneous transfer is configured (see
"DNP3 basic parameters" tab, "Transmission settings" parameter box.
Possible values: 0 ... 65535
Default: 0
"DNP3 station parameters" tab
This tab is shown only for interfaces with the connection mode "DNP3 station" or "node
station".
●
Specifies the number of basic intervals after which events in the station should be polled
by the DNP3 master. For the basic interval, refer to the "DNP3 master station
parameters" tab
This parameter is particularly important for event transfer if no spontaneous transfer of
events is configured (see "DNP3 basic parameters" tab, "Unsolicited transfer").
The value configured for the station is transferred to the master station and stored there.
Possible values: 0 ... 65535
Default: 1
●
Specifies the number of base intervals after which the class 0 data should be polled from
the image memory of the station. For the basic interval, refer to the "DNP3 master station
parameters" tab
The value configured for the station is transferred to the master station and stored there.
Possible values: 0 ... 65535
Default: 1
