transmission. The Create log report event must be set to occur before
the Create report event.
The transmission is not performed at the occurrence of these events,
instead when the transmission is made, the data previously read by these
events is sent. For information on how to configure the timing of the
actual transmission, see section
Transmission Control for Primary
Timers Setup for Secondary Transmissions
For secondary transmissions, the transmission and a given number of
retransmissions occur randomly within a defined interval. The length of
the transmission interval and the number of retransmissions are set with
the AWS Client software as described in section
for Secondary Transmissions on page 177
transmission interval is set up depending on the transmission type:
emergency or random transmission.
Emergency Transmission
When the emergency transmission is selected the report is sent as the
measured value passes the limit, for example, when the air temperature
rises above +30 °C. Emergency transmissions are set up in the Alarms
view of Lizard Setup Software by adding the Create report alarm. The
transmission interval, that is, the time within which the report is
randomly sent one or several times, will start 30 seconds after the report
is created. Under Condition, the Change delay parameter should be set
to a time that is longer than the transmission interval in order to prevent
the creation of overlapping transmissions.
Random Transmission
When random transmission is selected the report is sent at a fixed
interval, for example, once every six hours. The timing of random
transmissions is set up in the Timers view of Lizard. The transmission
interval, that is, the time within which the report is randomly sent once
or several times, starts 30 seconds after the Create report event.
NOTE
The Compress data event must be defined to occur before the Create
report event.
