This dialog box allows you to change the values of the network timers
and control LAN redundancy on your node. iFIX uses your entries in this
dialog box to tailor resources precisely for your configuration.
CAUTION: Modifying
network resources can seriously affect the performance of a node. You
should not use this dialog box unless you have a thorough understanding
of iFIX networking concepts.
The Advanced Network Configuration dialog box displays the following
items:
Network Timers
|
Field
|
Description
|
|
Keep Alive Field and Check Box
|
Allows you to specify the amount of time that, if
no activity has occurred over an established connection, a View client
waits before sending a heartbeat message. The default value for this field
is 20 seconds.
|
|
Send Field and Check Box
|
Allows you to specify the amount of time that a View
client waits for a request to the SCADA server to be acknowledged. If
this timer expires, the session ends. The default value for this field
is 30 seconds.
|
|
Receive Field and Check Box
|
Allows you to specify the amount of time that a View
client waits for a reply from the SCADA server. When running iFIX over
TCP/IP, the effective session timeout values is either the Send timer
or the Receive timer, whichever is greater. If this timer expires, the
session ends. The default value for this field is 60 seconds.
|
|
Inactivity Field and Check Box
|
Allows you to specify the amount of time that, if
no data activity has occurred over an established connection, a View client
waits before removing the dynamic connection from the list of outgoing
connections. If this timer expires, the session ends. The default value
for this field is 300 seconds.

|
Reset to Defaults Button
