Pseudos
Card 20 represents the system’s Analog Pseudo Points. These types of pseudo points store
analog values (the number 128, for example), and can be used as a threshold value within a
Custom Control equation. (For example, perform some action when the value of the Trouble
Count analog pseudo point [A2] reaches a specific value).
Double click on the Card 20 icon, shown in Figure 6-11, to display the system’s analog pseudo
points and their pre-assigned labels. This is a view-only screen and cannot be edited. Refer to

Table 6-6. Point Types for User-Defined Digital Pseudo Points
Point Type
Application
ALARM
Turning ON a digital pseudo point with this point type
causes an Alarm condition.
SUPV
Turning ON a digital pseudo point with this point type
causes a Supervisory condition.
TROUBLE
Turning ON a digital pseudo point with this point type
causes a Trouble condition.
UTILITY
A UTILITY digital pseudo point can hold a value of ON
or OFF, and is typically used as an ON/OFF switch
within a custom control equation.
Example. In the following custom control equation,
P76 turns ON only when the state of point 2-2 or 2-3 is
ON. P76 can then be monitored by other system
components, triggering other actions when it turns ON.
INPUT
ON/CODE 2-2
or ON/CODE 2-3
OUTPUT
TRACK ON P76 PRI 9, 9
