●
Max. polling period [s]
Specifies the maximum period for which the DNP3 master station can poll this station
continuously. Even if there is still data to be transferred in the station after this time,
polling is stopped by the DNP3 master station. As a result, the DNP3 master station is
available for other stations again.
The value configured for the station is transferred to the master station and stored there.
With the setting 0 (zero), the function is disabled; in other words the polling period is
unlimited.
Possible values: 0 ... 65535
Default: 10
●
Polling mode
Here you specify the mode with which the DNP3 master station polls the station.
The value configured for the station is transferred to the master station and stored there.
Ranges of values:
– Interval query
The stations are queried for the setting of the "Class 0 polling interval " parameter.
– Only after startup
The stations are polled only after the first startup of the TIM and after the station
restarts.
"CPU status" box
●
Signal CPU STOP with bit IIN1.6
If the CPU changes to STOP and if the option is enabled this leads to the following
reactions:
– A diagnostics message is entered in the diagnostics buffer of the station TIM.
– The CPU STOP is signaled to the partner.
To do this, the internal indication bit "IIN1.6" is set in the next message.
"Node station parameters" box
Preliminary overview: A node station TIM maintains the station process image in the image
memory for each lower-level DNP3 station.
●
Reply with current station image
– Option enabled
If the option is enabled, the node only replies to a class 0 poll if the process image in
the image memory of the node station is up to date.
– Option disabled
If the option is disabled, the node replies to a class 0 poll even if the process image in
the image memory of the node station is not up to date. When polled by a DNP3
master station, the data of all connected DNP3 stations is sent to the master station
even if one or more stations are not up to date.
