4.1.9 Application Program
You can divide the software in an Advant Controller 450 into system programs and application
programs. The application program is written in a high-level language AMPL. A user normally
only comes in contact with AMPL and definition of parameters for data base elements.
The application program consists of one or more PC programs and the data base.
4.1.9.1 Data Base
The data base in an Advant Controller 450 is a structured storage form for data which can be
used by several different internal program modules. For example, for all analog inputs, there is
structured data which stores the value, scale factors, limits, unit, deadband, and so on.
The data base is used, above all, for process I/O and functional units and is handled as DB
elements.
The data base contains data for, for example, the following functions.
•
Input and output boards:
–
Analog input boards (AI)
For standard current and voltage signals.
For temperature measurement.
–
Analog output boards (AO)
–
Digital input boards (DI)
–
Digital output boards (DO)
–
Pulse counter boards.
•
Parameters for S100 I/O Bus Extension, MasterFieldbus, Advant Fieldbus100, MasterBus
300, printers, EXCOM and GCOM.
•
