The following conditions can cause iFIX to temporarily lose a session:
- Running iFIX over a network that contains slow communication links (less than 256Kbps).
- Opening a picture containing many objects on the SCADA server while other iFIX nodes are requesting data from the SCADA server. In this case, the iFIX network task does not get the CPU time that it needs because other programs are competing for CPU resources.
Both of these cases can be solved by increasing the timer values that iFIX uses. These timer values are referred to as configurable session timers.
For more information on session timers, refer to the following topics.
