Addresses for Hardware Points
Overview
The AUTOPULSE Z-28 FACP contains many different types of points -- including read-only
system points, SLCnet channel points, points on optional cards, digital and analog pseudo
points, list points, and card status (trouble) points. Many of these points may be referenced,
using the point’s address, in Custom Control equations.
This section provides a card-by-card description of the AUTOPULSE Z-28’s hardware,
pseudo, and list points. Card Status points, which may only be viewed from the Active
Trouble List, the Historical Logs, or on an RS-232 port (if available), are not discussed in this
section.

points. Points with a type of U are user-configurable.
