TIM DNP3
106 System Manual, 12/2015, C79000-G8976-C253-04
●
Master station monitoring time [min]:
Monitoring time for the DNP3 master station. Within the configured time, the TIM expects
a signal from the DNP3 master station at the application layer.
If the TIM does not receive a signal from the master station during this time it assumes a
fault on the master station, outputs an error message to the diagnostics buffer and, if
configured, sets the relevant bit in the PartnerStatus system object to zero. The
configured value is transferred to the connected DNP3 master stations.
When the monitoring time has elapsed, the master station must send a 'Daily
Measurement' message to the station that must be acknowledged by the station. If the
station does not reply to the message, it is classified as being unreachable by the master
station.
Range of values: 0...65 535
Default: 0 (no monitoring)
Note: This mechanism can also be used for monitoring passive redundant paths.
●
Max. connection duration [s]:
Here, the maximum connection duration for dial-up connections can be set. A dial-up
connection will be terminated at the latest when the configured time elapses even if there
is still data to be transferred.
Range of values: 0 ... 65535
Default: 5
If you enter zero, the function is deactivated.
●
This parameter specifies how long after a connection abort, connection termination or
unsuccessful connection establishment, a new dial-up connection will be established at
the earliest.
Range of values: 0 ...255
Default: 0
●
This parameter specifies the form in which data messages are sent.
Range of values:
– Sending data messages as individual messages
– Sending several data messages as a block
Default: Single messages
