Figure 88 Data Acquisition Mode configuration
‘Min Saved Records’ defines minimum number of coordinates and I/O data that should be
transferred with one connection to server. If FM1010 does not have enough records to send to
server, it will check again after time interval defined in ‘Sending Period’.
Send period – GPRS data sending to server period. Module makes attempts to send
collected data to server every defined period. If it does not have enough records (depends on
parameter Min. Saved Records described above), it tries again after defined time interval.
GPRS Week Time tab – most GSM billing systems charge number of bytes (kilobytes)
transmitted per session. During the session, FM1010 makes connection and transmits data to a
server. FM1010 tries to handle the session as much as possible; it never closes session by itself.
Session can last for hours, days, weeks or session can be closed after every connection in certain
GSM networks – this depends on GSM network provider. GPRS Context Week Time defines
session re-establish schedule if session was closed by network. New GPRS context is opened if
time is 10 minutes till time checked in table. Therefore if all boxes are checked, FM1010 is able to
open new connection anytime. At scheduled time match FM1010 checks for GPRS session
activity. If GPRS session is alive, FM1010 sends data to server according to Send period
parameter. If it is not, FM1010 checks if it is able to re-establish the session.
