Section 4. Setting up Datalogger Networks
Apply to Other Stations – This button allows the schedule setup for this
datalogger to be copied to other stations in the network. Clicking the button
brings up a window that lists all of the dataloggers in the network. You can
select one or more dataloggers and then press OK to use the entered schedule.
To select more than one datalogger, hold down the Ctrl key while clicking the
dataloggers to select.
Base Date – The base date field is used to define the first date for scheduled
data retrieval. If the date entered in this field has already passed, a data
collection attempt will be made when the schedule is enabled and applied.
Base Time – This field is used to define the first time for scheduled data
retrieval. As with the Base Date field, if the time has already passed, a data
collection attempt will be made when the schedule is enabled and applied.
This setting is also used with the Collection Interval to determine the time data
collection will be performed.
Entering a zero for any of the intervals below will cause
LoggerNet to try and collect as fast as possible.
Collection Interval – This is the interval at which the datalogger will be
checked for new data. If this interval is set at 1 hour, new data will be
collected from the datalogger every hour.
Example: If the Base Date and Time are 1/1/99, 12:15 p.m., with an
interval of one hour, data collection attempts will be made at 15 minutes
past the hour, each hour.
Primary Retry Interval – If a data collection attempt is made but fails, you
can specify an interval on which another attempt will be made. This primary
retry interval starts at the time of failure, not on the original calling time and
interval. “Failures” may be caused by busy phone lines, noisy RF
environments, low batteries, damaged hardware, etc.
Number of Primary Retries – The number entered into this field is the
number of times the server will attempt to contact the datalogger on the
Primary Retry Interval. If all the collection attempts fail, then the server will
commence calling on the Secondary Retry Interval if it is enabled.
Secondary Retry Interval – If the secondary retry interval box is checked, the
specified interval is a calling interval that will be followed if all Primary
Retries fail. Data collection attempts will continue on the Secondary Interval
until a data collection attempt is successful, at which time, all retry statistics
are reset. The Secondary Retry Interval is based on the initial date and time
settings, not the time of the last failure. If the box is not checked the collection
schedule will return to the normal collection schedule and continue through the
primary retry schedule until communications are restored.
Typical use is to set the Primary Retries fairly close together, and the
Secondary Retry at a longer interval. For instance, if you are calling on an
hourly basis, the Primary Retries might be set to three tries, spaced five
minutes apart. The Secondary Interval then might be set at 2 hours.
