13.3 CS22 STANDARD DISPLAYS
Loading CS22 preconfigures the System Module display list for ten displays. The ten displays are
listed in Table 13-2 with appropriate reference sections, figure numbers, and configuration tables.
A configuration table is not listed for the Two Loop CON0 and CON1 display, as that information is
provided in this section. To configure the Horizontal Trend, Parameter, and System Status dis-
plays, reference the Section 4 and Section 5 information listed in the table. The Single Loop
CON0 and Single Loop CON1 displays will automatically be configured when the Two Loop CON0
and CON1 display is configured, with the exception of the Reverse Valve and Engineering Units
datapoints. These datapoints will also be covered in this section with the Two Loop CON0 and
CON1 display information.

13.4 CS22 DATAPOINT CONFIGURATION SELECTIONS
See Figure 13-2 and Table 13-3 to configure datapoints for CS22 - Two Loop Override Controller.
Table 13-3 also lists the Section 5 modules that can be referenced for more detailed definitions of
the datapoints when required.
A datapoint does not have to be configured if the default value
listed in Table 13-3 is appropriate for the process application. Loading CS22 initializes the En-
gineering Span (C258) to 100 for AI2 (Limiting Variable Loop) and sets C078 (Math A-K3) to 100.0.
Also, C089 (Math E-K2) is set to 1.0 and B202 is set to 138 for high limit override control.
