Workshop PG5
Write your first program
2.1 Manage your program files.
There are a lot of different kinds of files in a project. Here, we will cover
program files. There is three editors, and the format you choose to program
in, determines the editor you will use.
S-EDIT is the editor for programs written in IL ( Instruction list or AWL
in German ). IL is a kind of assembler code with 127 different instructions,
which work in combination with very powerful assembler directives.
This will be your tool if you plan to make very fast programs or if
you start to implement your own communication protocols into the PCD.
FUPLA is the editor for all the guys who like to edit their programs in a
graphical environment. ( Like ladder or logic)
The only difference between LADDER and LOGIC is in the way you draw
binary combinations. As soon as you use integer or floating decimal values,
both LADDER and LOGIC become very similar to work with. We
have implemented both LOGIC and LADDER into the same editor.
In addition to the large basic library, a large number of libraries for applications
like HVAC or communications via a modem, ( pager, modem … )
can be purchased.
GRAFTEC is the name of the editor in which you can draw
SEQUENTIAL BLOCS. It is a way to structure and display your program
in a sequential format. This is useful if you want to solve sequential problems
where you have to wait on some internal or external events before
starting the next program step.
