Description
Binary Inputs:
0 to 500
words
Number of digital input points to configure in
the DNP slave device based on a word
count. Each word stores 16 points.
Therefore, if the parameter is set to 2, 32
binary inputs will be defined for the
application.
Analog Inputs:
0 to 500
points
Number of analog input points to configure
in the DNP slave device. Each point will
occupy a one word area in the module
memory.
Counters:
0 to 250
points
Number of counter points to configure in the
DNP slave device. Each point will occupy a
two word area in the module memory. This
number corresponds to the number of
frozen counters. The application maps the
counters to the frozen counters directly.
Binary Outputs:
0 to 500
words
Number of digital output points to configure
in the DNP slave device based on a word
count. Each word stores 16 points.
Therefore, if the parameter is set to 2, 32
binary outputs will be defined for the
application.
Analog Outputs:
0 to 500
points
Number of analog output points to configure
in the DNP slave device. Each point will
occupy a one word area in the module
memory.
AI Deadband:
0 to 32767
data units
This value sets the global deadband for all
analog input points. When the current value
for an analog input point is not within the
deadband limit set based on the last event
for the point, an event will be generated.
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.
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:
Y or N
Set if the slave unit will send unsolicited
response messages. If set to N, the slave
will not send unsolicited responses. If set to
Y, 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.
