Data Log Reporting
Click the appropriate radio button to enable or disable the data log report feature.
Auto-Report Log File
Click on the link called Log to download the Auto-Report log. This log details the date and time of the
report, which type of report was sent, how the report was sent (email via modem or email via Ethernet),
if the report was sent successfully or not, and if not, what the problem was. You will be presented with
the standard Windows dialog box, asking if you want to open the file or save it. If it’s to be saved, it
asks what the file should be named and where you want the file to go. The file is a basic text file with a
.log extension that may be opened in any word processing program (Word, Notepad, etc.).
Logging Status
For information
Cyclical Log Duration
Select the maximum duration of the data log by clicking the radio button next to the time frame
required. The choices are Monthly, Bi-Weekly, Weekly, Daily, Every 12 hours and Hourly. Also select
the time of day for the report to be sent.
Important: If this unit is part of a network of controllers, you must stagger the reports from each
controller in the network to occur at least an hour apart. Failure to do this could result in lost reports!
Minimum Logging Interval
The minimum time between data points will be calculated based upon the number of parameters
selected to log between the Auto Report Datalog and the Manual Datalog, and the log durations.
Logging Interval
Type in the text box the time required between data points. If this is set to a particular value, and
changes to the logging parameters results in a larger minimum interval, the time previously set will be
replaced by the new minimum interval.
Event Triggered Logging
If the data needs to be collected only when triggered by an external event, such as an alarm condition or
a signal from a dry contact switch connected to a digital input, click Enable. A link to a list of possible
triggers will appear once the changes have been submitted. Click this link, select the events to use to
trigger data logging, then go back to the Auto Reporting page. The data will be collected for as long as
the trigger is active.
Select items to log
You will be presented with a list of all of the parameters that can be logged, including analog input
readings, totalizers, flow rates, and 4-20 mA input raw mA. The contents of the list will vary depending
on what options you have installed or programmed. Click the “Yes” radio buttons of the parameters that
you want to log, and the “No” radio buttons of the parameters that you do not want to log.
Log Files
Links to the last two copies of the log files are saved in the event that the emails fail to be sent
successfully. Click on the link to manually retrieve the file.
