LOGGING OVEN TEMPERATURE (DATA LOGGER FUNCTION)
WBV-4A Wi-Fi Bridge model supports data logging functionality. It can be set to periodically save a record
containing a precise date/time (derived from GMT time) and the corresponding oven temperature. By default,
this data is appended to daily log files, which are created at 00:00 AM and closed at 11:59 PM. These daily log
files are kept in the Bridge’s Flash memory until the Operator downloads/deletes them
using the File Editor
utility. The file name correspond to the file creation date. EX: file 20200325.txt contains all data points collected
on March 25
th
, 2020.
To setup the data logger configuration, use the ‘Log’ command, on the Command line window as follows.
5.1
“Log
[nn]
” command
The ‘Log’ command can be issued
without parameters, in which case it returns the Log operation state and the
current log interval. When used with
the ‘nn’ parameter,
it sets the number of minutes between data point
captures. If
‘
nn
’
is set to ‘00’, logging will not occur
(disabled).
NOTE: Whenever the user changes the Log interval or enables/disables Logging, the Wi-Fi Bridge will re-start.

ETTING LOG FUNCTION
On the left figure above, the ‘Log’ command is issued without parameters and the Bridge returns the
current
setting. The factory default for Model A is Logging Enable with Sample interval = 1 minute.
The figure on the right shows user setting Log sample interval to 10 minutes. After Enter is pressed, the new
value is saved and the Bridge resets itself. The user needs to manually refresh the page. If Log Sample
Interval is set to ‘00’, No logging will occur (Log Disabled).
