OATs contains an oscilloscope to view online-data graphically as an y-t-plot.
The oscilloscope can display all intrinsic data types except STRING and ANY.
The visualised data is taken from the USEND (IEC 61131 -5) function blocks on remote controllers or PLC. This ensures all signal values of a sample are consistent, i.e. sampled at the same moment in the controller.
The graphics can be copied to the clipboard or save to disk as JPEGs and collected data can be written into CSV-files for documentation and further analysis by other programs like Microsoft Excel® or OpenOffice Calc®.
