Data
Type of
Value
Range of Value
interface
Type of interface used for DNP3. See DNP3 Interface on DNP3 Master Settings
screen.
String TC P, U D P, S er i a l
serialBaud
Serial baud rate, used if interface=Serial. See Baud Rate on DNP3 Master
Settings screen.
Integer
9600, 19200,
38400, 57600,
11520 0
serialStopBits
Serial stop bits, used if interface=Serial. See Stop Bits on DNP3 Master Settings
screen.
Integer 1 or 2
serialParity Serial parity, used if interface=Serial. See Parity on DNP3 Master Settings screen. String None, odd, even
serialFlow
Serial flow control, used if interface=Serial. See Flow Control on DNP3 Master
Settings screen.
String
None, RTS/CTS,
XON/XOFF
addressMode
DNP3 addressing mode. See Addressing Type on DNP3 Outstation Settings
screen.
String Concentrator
gatewayAddress
DNP3 address of gateway. See Gateway DNP3 Address on DNP3 Outstation
Settings screen.
Integer 1 … 65,519
tcpKeepAlive See description for TCP Keepalive Timer on DNP3 Outstation Settings screen. Integer
Any integer
value
unsolicitedIndefiniteRetries
See description for Unsolicited Responses Retried Indefinitely on DNP3
Outstations Settings screen.
Boolean
0 (FALSE),
1 (TRUE)
unsolicitedResponsesToConfirm
See description for Number of Retries for Confirm on DNP3 Outstation Settings
screen.
Integer
Any integer
value
unsolicitedResponsesDelay See description for Delay Before Retries on DNP3 Outstation Settings screen. Integer 1 … 300
disableObjectFlagCommLost
This setting disables the COMM_LOST flag in DNP3 standard Object Flags.
When set to “true,” the gateway disables the COMM_LOST flag so it will always
be set to 0. When set to “false,” the gateway conforms to the standard definition
of COMM_LOST for DNP3 setpoints originating in the TripSaverII recloser. The
usage of the COMM_LOST flag can cause frequent DNP3 events.
Boolean True or False
dnp3InactivityTimerDuration
Length of time in minutes the gateway will wait for DNP3 traffic from a SCADA
master before performing recovery actions to restore DNP3 connectivity. A value
of zero (0) disables the DNP3 recovery mechanism.
Integer 0 - 1500
devicename
User-specified device name, to be reported via DNP3 in group 0, attribute 247. See
Gateway Name on Gateway Settings screen.
String n/a
gangOperationEnabled
This setting disables the Gang Operation feature in the gateway, independent of
the individual settings for the TripSaverII recloser. When set to “true,” the Gang
Operation feature is enabled and will operate according to the settings defined on
the Gang/Local tab for each TripSaverII recloser. When set to “false,” the Gang
Operation feature will not operate.
Boolean True or False
gangOperationMaxRetries
The maximum number of times the gateway will retry a gang operation after timing
out in its initial attempt. Used with gangOperationRetryTime. A value of zero (0)
disables the gang operation retry mechanism.
Integer 0 - 2592000
gangOperationRetryTime The time interval between gang operation retry attempts in seconds. Integer 1 - 3600
unsolRespDelayEventCount
The maximum number of DNP3 unsolicited events the gateway will queue before
sending to the SCADA master. A value of one (1) disables the queuing mechanism
so the gateway will immediately send all unsolicited events.
Integer 1 - 60
unsolRespDelayTime
The maximum amount of time the gateway will queue DNP3 unsolicited events
before sending to the SCADA master, in units of milliseconds.
Integer 100 - 120000
