[Section]/Item Value Range Description
Min Response Delay: 0 to 65535
milliseconds Minimum time between receiving a request
and transmitting a response. Allows master
time to disable transmitter on an RS-485
network.
Modem: Yes or No This parameter defines if a dial-up modem is
used on the secondary DNP slave port. A
modem cannot be used if the port is
configured as a master.
Connect Timeout: 0 to 65535 Defines the number of milliseconds to wait for
the CD signal to be set high. The CD signal
indicates a connection is made using a dial-
up modem.
First Character Delay: 0 to 65535 Defines the number of milliseconds to wait
before sending the first message after the
connection is first made. This delay only
applies to the first packet sent to the modem.
Redial Delay Time: 0 to 32000 Defines the minimum number of milliseconds
to wait before a redial attempt is made by the
slave.
Redial Random Delay: 0 to 32000 Defines a random millisecond time range to
be added to the redial delay time before the
modem is accessed.
Idle Timeout: 0 to 65535 Defines the number of milliseconds the
modem is inactive before it will disconnect.
Phone Number: ASCII String
Data This field contain a null-terminated, ASCII
character string used by the dial-up modem.
The string must contain all characters
required by the modem. An example string is
ATDT1800222333. Maximum length is 34
bytes including the terminating 0.
Collision Avoidance: Yes or No This parameter defines if collision avoidance
will be utilized on the primary DNP slave port.
CD Idle Time: 0 to 32000 Defines the minimum number of milliseconds
to wait before transmitting a message after
the CD signal is recognized as low.
CD Random Time: 0 to 32000 Defines the range of random time to be
added to the CD Idle Time before a message
will be transmitted from the slave.
CD Time Before Receive: 0 to 65535 Defines the number of milliseconds to wait
before receiving characters after the CD
signal is recognized as high.
BI Class: 0 to 3 This parameter specifies the default class to
be utilized for all the binary input points in the
DNP database that are not defined in the
override list section.
AI Class: 0 to 3 This parameter specifies the default class to
be utilized for all the analog input points in the
DNP database that are not defined in the
override list section.
