10.3.Data - log views
You can log eventually any data or information available in mySCADA. For the user convenience and easy access the data are grouped into so called “Data-Logs”. You can think of data-logs as of similar data collections. It can be e.g. a set of temperatures read each second from the PLC, motor start-up voltage and the current logged each 100 milliseconds, run hours of process, operators’ actions or computed production statistics.
Each data log can have defined multiple Data-Log Views. The data-Logs are thus viewed in a tabular form represented by one or multiple Data-Log Views. Data-Log Views are accessible from the main menu by clicking on “…” button.
There are two possible ways how to operate Data-Log views:
- Online – data is shown starting from the current value
- History – data is shown from a certain entered date
Time range showed in a data-log can be easily changed in the bar bellow the actual graph. Drag the slider to change the time range shown (from 1 minute up to 1 year).
Setting a custom time interval
When you click on a time interval on the right, you will be presented with a dialog enabling you to set up custom time interval for viewing.
Switch to history mode is done by clicking on the timer icon in the lower left corner.
In this mode, you can specify a date range in which data will be shown – click on a date to set:
By clicking on the left and right arrows, it is possible to change the date in accordance with already set Time range. Clicking on a left most arrow will show first records available, clicking on a right most icon will show latest records available. Again by clicking on a time interval on the right, you will be presented with a dialog enabling you to set up custom time interval for viewing.
- TIP: Maximum number of shown rows is limited by a LIMIT button located at the top bar. You can change this value any time during viewing a data.
