Setting Channel Parameters
The trend plot displays the last five minutes of the process for the
current channel. Three parameters are plotted: Process Variable (PV),
Output Value (OV), and Setpoint (SP).
The real-time trend plot screen is not editable. You cannot change the
parameters being plotted (PV, OV, SP) or change the time frame of the
graph. Use the plot for a quick view of your process, and as an aid when
tuning your control process.
In: Increases the plot’s vertical axis resolution.
Out: Decreases the plot’s vertical axis resolution.
Last: Returns the plot to the last vertical axis scaling values.
Scale: Scales the trend plot to fit into the size of the plot window.
Channel Setup Tabs
The Channel Setup screen contains five tabs, shown in Figure 5-4, that
allow you to set the parameters for the channels. Refer to your controller
