14.3 CS40 STANDARD DISPLAYS
Loading CS40 preconfigures the System Module display list for ten displays. The ten displays are
listed in Table 14-2 with appropriate reference sections, figure numbers, and configuration tables.
A configuration table is not listed for the Four Loop CON0 - CON3 display, as that information is
provided in this section. To configure the Horizontal Trend, System Status, and Status Module dis-
plays, reference the Section 4 and Section 5 information listed in the table. The Alarm Summary
display does not have to be configured; however, it is described and illustrated in Section 4.

14.4 CS40 DATAPOINT CONFIGURATION SELECTIONS
See Figure 14-2 and Table 14-3 to configure datapoints for CS40 - Dual Two Loop Cascade Con-
troller. Table 14-3 also lists the Section 5 modules that can be referenced for more detailed defini-
tions of the datapoints when required.
A datapoint does not have to be configured if the
default value listed in Table 14-3 is appropriate for the process application.
Loading CS40 in-
itializes the Engineering Spans to 100 for AIs 1-3 (C257, C258, and C259). Also, C076 (Math A -
K1) is set to 1.0, C077 (Math A - K2) is set to -1.0, C085 (Math D - K1) is set to 1.0, and C086
(Math D - K2) is set to -1.0. The CON0

OUT and CON1

OUT signals, which are the secondary set-
point inputs, must be properly scaled by configuring datapoints C184 (B1) and C185 (K1) for the #1
Secondary Control Output; and by configuring C220 (B1) and C221 (K1) for the #2 Secondary Con-
trol Output. These datapoints are listed in Table 14-3 under their respective CON
•
OUT Datapoints.
