Unsolicited Responses
When enabled (the default), the control sends a message to the master station when new
event data are available based on the
Unsolicited Transmit Delay Event Count
setting
and the
Unsolicited Transmit Delay Time
setting. A Master Station DNP address and
master station port code or master station IP address must be entered. Enabling this
feature may add significant traffic to your communication network.
Unsolicited Response Mode
Select the
Normal
(default) or
5800 V2 Mode
setting. The
Normal
mode requires the
master station to acknowledge an initial empty (null) unsolicited message at control
restart. The SCADA master must send a command to enable unsolicited reporting.
If acknowledgment of the initial empty unsolicited message is not received, the
control continues to resend these messages at the configured retry interval until an
acknowledgment is received. The
5800 V2 Mode
setting is a non-standard mode that
bypasses the initial empty unsolicited messages and the requirement for the master
station to enable unsolicited reporting with a SCADA command. It simply starts sending
unsolicited responses as events occur, provided the unsolicited responses parameter is
enabled.
The
5800 V2 Mode
setting may require restarting the control unless the control is
presently sending unsolicited responses in the
Normal
mode or a remote command
to enable unsolicited responses can be sent to the control. To restart the control
after all configuration changes have been successfully applied, select Tools>Device
Maintenance… on the menu bar, and then select the
Reset Control
option and click on the
Yes
button in the dialog box. Then log in when the IntelliLink software dialog box opens.
Failover IP Address (if applicable)
Each of the six master stations can have up to four Failover IP addresses registered.
The local control sends unsolicited messages (if enabled) to any registered master it
has received a message from (provided the master has sent an
Enable Unsolicited
Messages
command and the
Unsolicited Response Mode
is set to the
Normal
state).
The local control will respond to either the primary master or the failover master,
whichever sent the last message. The IP address in use will be highlighted. If there is
no
Failover
setting configured for this master, leave this entry blank or enter 0.0.0.0.
Failover TCP Interface (if applicable)
Each of the six master stations can have up to four failover TCP interfaces configured.
Select the
Add-On
setting for IntelliRupter fault interrupters.
Report Last Analog Input Event Only
When the
Report Last Analog Event Only
setting is set to the
Enabled
state, only
the latest DNP analog input events will be reported for a DNP analog input point (both
solicited and unsolicited messages); otherwise, all analog input point changes will be
reported when this setting is in the
Disabled
state, which is the default.
