If you use dataloggers from Campbell Scientific, or run datalogging systems for research, education, weather, forestry, mining or aqua-fish (to name but a few), read on about the powerful VDV database applications.

Vista Data Vision set of applications are built on the experience we have gained by running our own successful data service bureau for years.

Reports from our users indicate that we are right, there is great need among data logging experts for powerful and easy-to-use applications for storing data, browsing and reporting and to publish data to the web.

ALARMS - Powerful alarm tools are now available for db.robot.c pro. Using alarms, you can test every variable from every datalogger against LL, L, H and HH threshold limits. You can have single staff list to send alarms to, or a complex set of groups working in shifts. And, you can split your alarms for maintenance group and user group. You can add header and footer to your messages, and send alarms as email and/or sms. If this is not enough, there is provision to send reminder messages once a day to staff members in those well-run data systems that (almost) never have alarm situation, just so they know that the alarm system is in good working condition.

FILE UPDATE NOTIFICATION - Most useful feature for all those data system operators who seek easier way to keep their system up and running. File Update Notification feature is part of db.robot.c pro. You use it to monitor if new data is really arriving from dataloggers. If latest data from a datalogger is older than a set value (2 hours or 12 hours or any time threshold), then alarm message is sent to staff members. And, you can set time threshold individually to each datalogger you are retrieving data from. Now, you do not need to sleep by your Loggernet-PC any longer.

AUTO REFRESH - Auto Refresh is part of db.data.browser standard and pro, and is most useful for all those operators who would like to see data being populated to graphs as soon as it has been retrieved from a datalogger. Before, you would have to press the Latest Data button all the time to have the graph to send new query to the MySQL db for latest data. But not any longer. Make Auto Refresh active and db.data.browser will do it for you, just like in any SCADA system.

USER LOGO - We have had inquiries about customization of the feel and look of the web pages for graphs and reports in db.web.browser pro. In version 3.3, we added Information pages, Latest Value on Map and Service Bureau logo. Now, we added client’s logo to the upper right corner of the web page. When client has logged into a VDV data website, he will see his own company logo, as an indication of the fine customized service his Service Bureau is providing.

LATEST TIME STAMP - Up to now, you needed to display data as table to see the actual time stamp of the latest data on graph. Not any longer. When you click on graph to enlarge it to full size, time stamp of latest data on graph is on display in clear text.

QUESTION: In my CR1000 datalogger, I have logged all my temperatures in degrees Fahrenheit. However, I need to display temperature as degrees Celsius. What can I do?

ANSWER: You can use the Virtual Variable feature of db.data.browser to create new virtual (calculated) variable Temp°C=(Temp°F-32)*5/9. Then, you add the new Temp°C to any graph. When you browse this graph, either in db.data.browser or on the web, the new Temp°C variable is re-calculated and updated on the fly. You can use Virtual Variables to make sum or average out of many variables and to calculate new complex results. Because of Virtual Variables, it is now possible to “repair” missing data that usually is calculated or prepared in the datalogger.
