• Manually Rearm
To manually rearm the trigger, issue the Rearm Plot (103) command. You can also
issue the Rearm Plot command from the Plot Manager by choosing Rearm Plot on
the Online menu. To enable manual rearming, see the Changing the Trigger
Settings section below.
Rearming a plot will clear all previously captured data for that plot.
Changing the Trigger Settings
The trigger settings can be configured for each individual plot. To change the trigger
settings for a plot, follow these steps:
1. In the Plot Template Editor, on a plot tab, choose Custom.
2. In the Trigger Settings area, click Edit Trigger Settings.
3. Make the desired changes and click OK.
4. To apply any changes to the RMC, click the Download button in the Plot Template
Editor toolbar.
3.9.4. Using Plots with a Host Controller
RMC plots can be controlled from a PLC or other host controller. To start, stop, or trigger a
plot, use the plot commands. For additional information on using RMC plots, see the Plot
Overview topic.
Plot Commands
The RMC has several commands specifically for plots.
Start Plot (100)
Stop Plot (101)
Rearm Plot (103)
Trigger Plot (102)
Enable/Disable Plot Trigger (104)
Reading RMC Plots with a PLC
The RMC plots can be read with a PLC, HMI, or other host controller. For details, see the
Reading Plots with a Host Controller topic.
3.9.5. Reading RMC Plots with a Host Controller
This topic describes how to read the RMC plots with a PLC, HMI, PC (via RMCLink) or other
host controller. If you need help on viewing RMC plots in RMCTools, see the Plot Overview
topic. For help on configuring the plots, such as changing the sample period or which registers
are plotted, see the Plot Template Editor topic.
Determining which Data Items to Read
The RMC plot data items you can read via a host controller are not necessarily the same
as the items displayed in the Plot Manager because the Plot Manager calculates some
items. For example, some velocities are not actually uploaded from the controller, but are
calculated from the position data.
