7.3 CS2 STANDARD DISPLAYS
Loading CS2 preconfigures the System Module display list for five displays. The five displays are
listed in Table 7-2 with appropriate reference sections, figure numbers, and configuration tables. A
configuration table is not listed for the Analog Backup Controller Single Loop CON0 display, as that
information is provided in this section. To configure the Single Loop CON0 with Horizontal Trend,
Parameter, and System Status displays, reference the Section 4 and Section 5 information listed
in the table.

7.4 CS2 DATAPOINT CONFIGURATION SELECTIONS
See Figure 7-3 and Table 7-3 to configure datapoints for CS2 - Analog Backup Controller.
Table 7-3 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 7-3 is appropriate for the process application.
Loading CS2 initializes the Engi-
neering Span (C259) to 100 for AI3 (Control Element Feedback). Also, the DO0 (Computer Output
Diverter) Contact Input Invert (L288) is set to 1 and datapoint C078 (Math A - K3) is set to 100.0.
