9.2 Background Task Processing
You can tell ProSoft i-View to keep connections alive even when the device (iPhone,
iPod) is locked. Additionally, ProSoft i-View supports running in the background during a
finite period of time on multitasking enabled devices. On the Settings tab, there are two
switches that allow for enabling such options.
9.2.1 Keep Connected
When ON, ProSoft i-View will keep any open connection as is and will continue polling
PLCs even when the device is locked. This is intended to help keep alarms and graphs
updated, but it may have a negative impact on battery life.
When OFF, ProSoft i-View will close any open connection when another application
becomes active or the device goes to the locked state, either by the Auto-Lock timeout or
by pushing the bottom on the edge. This will prevent excessive battery drain and may
reduce carrier fees in case of cellular remote connections. When the device is unlocked
and ProSoft i-View becomes active again, communications with PLCs will be restarted.
