1.)
The “measure interval” on the LCom is fixed at 1 minute and can not be
changed. The measure interval on the LCom is the same for all channels (not
on a “per sensor channel” basis).
2.)
The “Storage Interval” on the LCom does not really refer to the interval in
which the sensor values are stored in the ring memory (on the SD card). The
LCom always stores the measure values in the “Measure Interval” (i.e. every
minute).
However, if the MSSI “Storage Interval” is set to a value greater than one
minute, the stored data will be reported in the specified time period (e.g. 10
minutes). If “Calc Min/Max/Avg/Sum Values” is active (the default), the LCom
will calculate the min/max/avg or sum for the sensor value over the specified
“Storage Interval” (which is in accordance to the MSSI protocol specification).
If “Calc Min/Max/Avg/Sum Values” is not active, only the last value for the
specified time period will be reported. Note that in this case “sum” values (like
precipitation amount) are NOT correct, as the last stored value always only
refers to the last minute, not the complete “Storage Interval” time period.
3.) Signaling of warnings and alarms is not supported by the LCom (this is an
optional feature of the MSSI protocol).
