5.6. REAL-TIME GRAPH
5.6 Real-time Graph
This function displays selected parameter data in real-time graphical format
for monitoring purposes. Users can view both tabular and graphical data
using this feature.
The Real-time Graph logs data from the truck ECU’s. Data is displayed and
stored on the user’s PC. The PC must be connected to the truck ECU for
this feature to work. This feature allows the user to view data in a graph or
tabular format.
During data logging, data is downloaded from the controller being logged
to the PC running WEST. Because the data is being recorded to the PC,
the logging time available is only restricted by the memory available on the
PC. The maximum logging speed, or number of data samples recorded per
second, is determined by the number of parameters selected to be logged.
The advantage of the real-time graph is that data can be viewed in tabular
or graphical form while the data is being recorded.
