8.2.4
DNP Transfer Protocol
The DNP Transfer Protocol settings modify the
DNP MINT interface procedures to the DNP
network. These settings are only used when the
DNP MINT is functioning in the run (non
configuration) mode.
A DNP MINT or device setting with the “Enable
Solicited Static/Event Data Link Confirm” bit
reset / set will return solicited data to the master
device
using
the
UNCONFIRMED_USER_DATA
/
CONFIRMED_USER_DATA data link function
code, respectively. If set, data link transfers that
do not receive a confirmed response will be
retried depending on the “Data Link
Confirmation Retry Count” setting.
A device setting with the “Enable Unsolicited
Event Data Link Confirm” bit reset / set will
send unsolicited data to the master device using
the
UNCONFIRMED_USER_DATA
/
CONFIRMED_USER_DATA data link function
code, respectively. If set, data link transfers that
do not receive a confirmed response will be
retried depending on the “Data Link
Confirmation Retry Count” setting.
A DNP MINT or device setting with the “Enable
Solicited Static Application Confirm” bit set will
return solicited data to the master device with
the CON bit set (requesting a confirmation).
Note that all event data being returned are
required to set this CON bit.
A device setting with an “Enable Unsolicited
Class 1/2/3 Events” bit set will send unsolicited
data to the master device after the occurrence of
an event for that enabled class.
The DNP MINT binary counter objects cannot
be enabled for unsolicited messaging (i.e., set to
Class 1, 2 or 3). Thus setting the “Enable
Unsolicited Event Data Link Confirm” or
“Enable Unsolicited Class 1/2/3 Events” bits for
the DNP MINT summary would provide no
functionality.
8.2.5
DNP Network Idle Time To
Initiate Unsolicited Transmission
The DNP Network Idle Time To Initiate
Unsolicited Transmission setting is the number
of 10 ms increments the DNP MINT will wait
for the DNP network to be silent (inactive)
before it will attempt to transfer a pending
unsolicited message. This value is set in the
DNP MINT summary table and applies to all
DNP MINT messages (DNP MINT counters and
its 16 devices).
8.2.6
DNP Network Unsolicited Retry
Random Time Increment Mask
The DNP Network Unsolicited Retry Random
Time Increment Mask setting is used to mask a
random number generated by the DNP MINT
which will be added (in 10 ms increments) to the
DNP MINT to retry an unsuccessful
(unconfirmed) unsolicited message transfer
attempt. The additional time increment is added
to the DNP Network Idle Time if a message
different from the expected confirmation is
received. It is added to the DNP Application
Confirmation Wait Timeout if no response is
received. This value is set in the DNP MINT
summary table and applies to all DNP MINT
messages (DNP MINT counters and its 16
devices).
8.2.7
DNP Data Link Confirmation
Wait Timeout
The DNP Data Link Confirmation Wait Timeout
setting is the number of 10 ms increments the
DNP MINT will wait for a Data Link
confirmation from the master device, providing
data link confirmations are enabled (see
Section
8.2.4
). This value is set in the DNP MINT
summary table and applies to all DNP MINT
messages (DNP MINT counters and its 16
devices).
