Concept provides an editor for each programming language. These editors contain
custom menus and tool bars. You can select the editor to be used as you create each
program segment.
In addition to the language editors, Concept provides a data type editor, a variables
editor and a reference data editor.
With the IEC 1131-3 function block diagram language, you can combine elementary
functions, elementary function blocks (EFBs) and derived function blocks (all three of
which are known as FFBs) with variables in an FBD. FFBs and variables can be
commented. Text can be freely placed within the graphic. Many FFBs offer an option
for input extensions.
Concept provides various block libraries with predefined EFBs for programming an
FBD. EFBs are grouped in the libraries according to application types to facilitate the
search.
In the FBD editor, you can display, modify and load initial values; current values can
be displayed. The CLC and CLC_PRO libraries allow you to display animated
diagrams of the FFBs and a graph of the current values.
For custom function blocks (DFBs), the Concept-DFB editor is used. In this editor, you
can create your own function blocks from EFBs or existing DFBs. DFBs created in the
FBD editor can be recalled in the LD, IL and ST editors, and DFBs created in the LD, IL
and ST editors can be used in the FBD editor.
With the IEC 1131-3 ladder diagram language, you can build an LD program with
elementary functions, function blocks and derived function blocks (all of which are
known as FFBs), along with contacts, coils and variables. FFBs, contacts, coils and
variables can be commented. Text can be placed freely within the graphics. Many
FFBs offer an option for input extensions.
The structure of an LD segment corresponds to that of a current path for relay
circuits. On its left side is a left bus bar, which corresponds to the phase (L conductor)
of a current path. As with a currentpath, only the LD objects (contacts, coils) connected
to a power supply (i.e., connected to the left bus bar) are processed in LD
programming. The right bus bar, which corresponds to the neutral conductor, is not
visible. However, all coils and FFB outputs are internally connected to it in order to
create a current flow.
The same EFB block libraries available for the FBD editor can be used in the LD
editor to program a ladder diagram.
In the LD editor, inital values can be displayed, modified and loaded; current values
can be displayed. For the EFBs in libraries CLC and CLC_PRO, animated diagrams
of the FFBs and a graph of the current values can be displayed.
For custom function blocks (DFBs), the Concept-DFB editor is used. With this editor,
you can create your own function blocks from EFBs or existing DFBs. DFBs created in
the LD editor can be recalled in the FBD, IL and ST editors, and DFBs created in the
FBD, IL and ST editors can be used in the LD editor.
