[Section]/Item Value Range Description
Float Class: 0 to 3 This parameter specifies the default class to
be utilized for all the floating-point input points
in the DNP database that are not defined in
the override list section.
AI Deadband: 0 to 32767 This parameter specifies the default
deadband value assigned to all points not
defined in the override list for the analog input
point type in the DNP database.
Float Deadband: 0 to maximum
float value This parameter specifies the default
deadband value assigned to all points not
defined in the override list for the floating-
point input point type in the DNP database.
Select/Operate Arm
Time: 1 to 65535
milliseconds Time period after select command received in
which operate command will be performed.
After the select command is received, the
operate command will only be honored if it
arrives within this period of time.
Write Time Interval: 0 to 1440
minutes Time interval to set the need time IIN bit
(0=never), which will cause the master to
write the time. Stored in milliseconds in the
module memory.
Data Link Confirm Mode: Coded Value
(N=Never,
S=Sometimes,
A=Always) IED can request acknowledgement from
master station when sending data. The codes
are as follows: 0=Never, 1=Sometimes,
2=Always
Data Link Confirm Tout: 1 to 65535
milliseconds Time period to wait for Master Data Link
confirmation of last frame sent. This time is in
milliseconds. This parameter is only used if
the frame is sent with confirmation requested.
Data Link Max Retry: 0 to 255
retries Maximum number of retries at the Data Link
level to obtain a confirmation. If this value is
set to 0, retries are disabled at the data link
level of the protocol. This parameter is only
used if the frame is sent with confirmation
requested.
App Layer Confirm Tout: 1 to 65535
milliseconds Event data contained in the last response
may be sent again if not confirmed within the
millisecond time period set. If application
layer confirms are used with data link
confirms, ensure that the application layer
confirm timeout is set long enough.
Unsolicited Response: Yes or No Set if the slave unit will send unsolicited
response messages. If set to No, the slave
will not send unsolicited responses. If set to
Yes, the slave will send unsolicited
responses.
Class 1 Unsol Resp Min: 1 to 255
events Minimum number of events in Class 1
required before an unsolicited response will
be generated.
Class 2 Unsol Resp Min: 1 to 255
events Minimum number of events in Class 2
required before an unsolicited response will
be generated.
