Using Plots
The RMC provides very flexible plotting capabilities.
Virtually any register in the RMC can be plotted, and multiple registers
may be plotted simultaneously. The plot trigger allows events to easily
be captured. Plots can be controlled and viewed as time-based or XY plots
with the Plot Manager in RMCTools. Plots can be also be started and read
via a PLC or other host controller.
Use the Plot
Manager to view plots in RMCTools.
How to Plot a Move in RMCTools
See the Plot
Manager for more details.
Viewing a Captured
Plot
When an axis receives a motion command, the
RMC stores a plot of the motion internally, which can be uploaded and
viewed.
-
Send a motion command to an axis, such as Move Absolute (20).
-
In the Project Pane, double-click Plots to open the Plot Manager.
-
On the Plotting tab, click the Capture
button to upload the plot.
If you sent a command to Axis 0, upload Plot 0. If you sent a command to Axis 1, double-click Plot 1, and so on.
-
The Plot Manager will open and the plot will automatically upload.
-
The plot will be automatically sized to fit to the plot window. Use the toolbar buttons to zoom in and out, or Ctrl + mousewheel.
You can specify the capture duration in the
Plot
Template Editor.
Trending a Plot
RMCTools can trend a plot in real time.
-
In the Project Pane, double-click Plots to open the Plot Manager.
-
On the Plotting tab, for the desired plot template, click the Trend
button.
-
Send any motion commands to move the axis.
-
To stop the trend, click the Stop Trend
button.
You can specify the trend duration in the Plot
Template Editor. When the trend reaches the duration, the trend will
continue and old data will be lost.
Viewing Plots in RMCTools
The Plot Manager can be used to view, trigger,
save, and export plots. See the Plot
Manager topic for details.
Setting Up Plots
Use the Plot
Template Editor to change the plotted registers, number of plots,
plot duration, pen colors, plot trigger, etc.
Saving and Exporting Plots
Plots in the Plot Manager can be saved for use
later in the Plot Manager, or to send to Delta for technical support.
Individual plots can be exported to a file that can be used by other programs,
such as Excel, Word, etc. For more details, see the Saving
and Exporting Plots topic.
RMCTools automatically saves a backup copy of
every uploaded plot to an internal folder on the PC in order to prevent
data loss if the user forgets to save plots before closing RMCTools. For
details, see Auto-Saved
Plots.
Plot Commands
You can use the
following commands to start, stop and trigger plots. Issue these commands
like any other command. Some of these commands can also be issued directly
from the Plot
Manager. See each command topic for more details.
Reading Plots with a PLC, HMI, or other Host Controller
For details on how to read RMC plots with a
PLC, HMI, or other host controller, see the Reading
Plots with a Host Controller topic.

For the RMC75 and RMC150, the storage is equally
divided between the plots. For the RMC200, each plot uses only the storage
it needs.
