Note:
1
The GUI can read the data only from the smart monitoring station (STEVAL-IFS014V1).
USB communication is not available in the smart monitoring node (STEVAL-IFS015V1).
2
The GUI reads the data from the board only once at startup and then processes that data.
Once the file is read from the board, the board can be removed and can exit the USB mode.
3
As long as the station is in USB mode, all other operations are stopped. The station should
not be kept in USB mode for a long time after reading the file using the GUI to prevent losing
the wireless link and data.
3.5 Alarm
system
The system has the capability to detect various alarm conditions and give indication to the
user. The system gives warnings for the following conditions.
3.5.1
Threshold crossing of weather parameters
The smart monitoring station and all the active nodes can be configured to display warnings
upon crossing the maximum or minimum threshold of any of the weather parameters.
Whenever any weather parameter of any node crosses the configured maximum or
minimum limit, then that node sounds an alarm. At the same time this information is
transferred to the smart monitoring station through ZigBee and an alarm sounds also at the
smart monitoring station along with the warning on the display (see
).
Figure 14.
Warning
messages
All the nodes and the smart monitoring station function in this manner.
Note:
For displayed warnings, if the user acknowledges the alarm by pressing the screen of the
STEVAL-IFS014V1 when the warning is displayed on the screen, then the alarm does not
post again for some time (~15 minutes). During this time interval the user can remove the
cause of the alarm. If, after that time has passed the condition re-occurs, then the alarm is
displayed again.
3.5.2 Node
movement
Whenever any active node of the system vibrates or moves from its place, an alarm sounds
at the node. At the same time, this information is transferred to the smart monitoring station
along with the severity level of the movement. At the smart monitoring station an alarm
sounds along with the alarm message on the display as shown in
