After the Sensor Table and Group definitions are completed, they are saved in the configuration
Flash Memory with all the other radio setup command parameters.
5.9.3 Periodic Data Collection
After the Sensor Table is set up, a schedule needs to be created to tell the radio when to collect
the data and when to build and transmit the SDATA reports.
A data collection command is periodically scheduled which uses the row number to trigger the
collection of data for that row. The data measurements that are returned by the sensor are stored
in the sensor table. Up to 64 measurements for each row can be stored.
The SDI,COLLECT,1,2,3,4,… command triggers data collection for all the rows in that
command. Once all the data is collected and stored in the table for one SDI,COLLECT command
the radio can go to the next scheduled command. There can be several commands scheduled to
collect all the data for each reporting interval.
Following the data collection commands, the commands to build and transmit each SDATA
group report are scheduled. This is the EVENT, UPDT, G command where ‘G’ is the desired
GROUP number.
The schedule is also saved in the radios configuration Flash memory. An example for our Sensor
Table might be:
SCHED,INTERVAL,1:0:0,SDI,COLLECT,1,2,3,4
SCHED,INTERVAL,1:0:0,OFFSET,15,EVENT,UPDT,1
SCHED,INTERVAL,1:0:0,OFFSET,15,EVENT,UPDT,2
This will repeat every hour and take up to 15 seconds to collect the data, then create the SDATA
reports.
To summarize: (1) the Sensor Table and Groups are defined, (2) the schedule commands are
created, (3) this is SAVE’d in the configuration Flash memory, and (4) the radio periodically
collects and then transmits the data to its Master station.
5.9.4 Data Logging
The 565 is not a data recorder, but does have the ability to log trace files. A USB memory stick
can be plugged into the front of the 565 and set up to log the maintenance port trace output. This
will log all the SDATA reports as they are created. The USB device can be exchanged for a new
one when it is filled. The USB device can then be delivered to the Customer for data analysis.
The USB device has a DOS 6.2 file format with a new log file for each day. The user will have
to provide software to extract the data from the log files.
