A special font or typeface is used to indicate parameter names
and text seen in the
AnaWin3
screens.
Figure 5.1
Sample Text
The words
Process Variable Low
and
Input Signal Low
represent
parameter names. The words
(PV Lo)
and
(Input Signal Lo)
are the
abbreviated terms seen in
AnaWin3
. These abbreviations are
shown for reference in this chapter only when the
AnaWin3
name differs from the listed parameter names.
The PPC-2000 Database
The PPC stores setpoints and other control parameters along
with process variable values and digital I/O states in its
database. The database is analogous to a set of tables.
Parameters form the columns of the tables.
AnaWin3
, third-
party HMI software, operator interface terminals and
LogicPro
programs access these process parameters and data in the
database.
Think of the database as a series of tables. Each table holds the
values of a different set of parameters: analog inputs; channels;
digital I/O; analog outputs; soft integers; soft booleans; and
globals. In each table the columns represent parameters and
the rows represent analog inputs, or channels, or digital I/O
and so on.
For example, in the analog input table, the columns represent
the analog input parameters such as
Input Value, Input Type,
and
Input Filter
. Each row holds the settings of each of these
parameters for a particular analog input.
