Figure 20 Realtime plotting and logging
The HMI provides basic plotting and logging facilities that can be used to check the operation of the system or
monitor the performance. It is not intended for production or extended logging as the log is maintained in one plain
text file with minimum validation.
Up to two traces can be selected using the drop-down lists Line 1 & 2. The items are sampled once a second and
added to the trace. If logging has been selected they are also recorded to the text file that was selected. The items
selected can be changed at any point, but on doing so the trace is cleared before plotting resumes with the new
items. If the items are changed whilst logging to a file is in progress the logging simply carries forward with the new
items being logged, causing a discontinuity in the log file.
The display options settings affect how the scope data is displayed this no effect on logging.
Display Option Effect
Show Scope
Displays the scope in a window below the main application display.
Auto scale
Increases or decreases the Y axis range so that all the recorded Y values fit within the axis.
Clear data
Erases the current data from the trace, using this when Auto Scale is selected causes the axis to
expand the range to fit
Time Span
This can be used to adjust the plots X axis from 1 minute to 24 hours, this can be done at any
point and does not cause any loss of data as the data is stored in a rolling 24-hour buffer.
