Delta RMC151 - Manual (Page 857)

8 Command Reference
This command stops a continuous plot capture immediately. This allows RMCTools to read
up the entire plot without any gaps. Plots are either continuously capturing data or done
capturing data. Compare this with the Start Plot (100) and Trigger Plot (102) commands.
To find out more about plotting, see the Using Plots topic.
8.9.3. Command: Trigger Plot (102)
Supported Axes: All
Firmware Requirement: 1.00 or newer

Description
This command triggers a plot. Triggering a plot means to start a plot, and include plot
data from before the moment at which plot was triggered. This is very useful for
troubleshooting. For example, if a plot is triggered when an error occurs, the plot can
show data from before the error occurred, giving the user insight as to what happened.
The amount of plot data included from before the trigger is defined by the Pre-Trigger
Percent in the Plot Template Editor. The default Pre-Trigger Percent is 0%, which means
no data from before the trigger will be included. In order to include data from before the
trigger, the Pre-Trigger Percent must be greater than zero and the plot Rearm Mode in
the Plot Template Editor must be set to Manual Rearm.
When the plot is set to Manual Rearm, the Rearm Plot (103) command must be issued
before triggering the plot. Notice that rearming a plot will clear all previously captured
data for that plot. If a plot is triggered immediately after rearming it, and the Pre-Trigger
Percent is greater than 0%, the plot will not contain any data before the trigger. After
rearming, there must be a delay long enough to record the data to fill the plot before the
trigger time.
If the plot trigger has been disabled, this command will be ignored. The plot trigger is
automatically disabled while in Trend Mode in the Plot Manager, or can be disabled with
the Enable/Disable Plot Trigger (104) command.
This command differs from the Start Plot (100) commands in the following ways:
• The Start Plot (100) command will start a plot that only includes data from after the
Start Plot command was issued.
• The Start Plot (100) command starts a new plot immediately, even if the specified Plot
number is currently capturing a plot. The Trigger Plot (102) command will not trigger a
plot if the specified Plot Number is currently capturing a plot.
Plots can also be triggered automatically when a motion command is issued to an axis. To
find out more on triggering, see the Triggering Plots topic.
