[Section]/Item Value

Range

Description

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.

Class 3 Unsol Resp Min:

1 to 255 events Minimum number of events in Class 3 required before

an unsolicited response will be generated.

Unsol Resp Delay:

0 to 65535
milliseconds

Maximum number of 1 millisecond intervals to wait after
an event occurs before sending an unsolicited response
message. If set to 0, only use minimum number of
events.

Uresp Master Address:

0 to 65534

DNP destination address where unsolicited response
messages are sent.

Uresp Retry Count:

0 to 255 retries Determines the number of unsolicited message retries

sent on primary DNP port before changing to secondary
port. If the value is 0, port switching will be disabled.

AI Events with time:

Yes or No

This parameter sets if the analog input events
generated by the module will include the date and time
of the event. If the parameter is set to No, the default is
set to no time data. If the parameter is set to Yes, the
default object will include the time of the event.
