BESTlogic+ Composition
There are three main groups of objects used for programming BESTlogic+. These groups are I/O,
Components, and Elements. For details on how these objects are used to program BESTlogic+, see the
paragraphs on Programming BESTlogic+.
I/O
This group contains Input Objects, Output Objects, Alarms, Pre-Alarms, and Senders. Table 5-1 lists the
names and descriptions of the objects in the I/O group.
