Concept is a software configuration and application programming tool for the
Momentum automation platform. It is a Windows-based software that can be run on
a standard personal computer. The configuration task can be carried out online (with
the PC connected to the Momentum CPU) or offline (PC only). Concept supports the
configuration by recommending only permissible combinations, thereby preventing
misconfiguration. During online operation, the configured hardware is checked
immediately for validity, and illegal statements are rejected.
When the connection between programming unit (PC) and Momentum CPU is
established, the configured values (e.g., from the variables editor) are checked and
compared with actual hardware resources. If a mismatch is detected, an error message
is issued.
Concept editors support five IEC programming languages:
b Function block diagram (FBD)
b Ladder diagram (LD)
b Sequential function chart (SFC)
b Instruction list (IL)
b Structured text (ST)
as well as Modsoft-compatible ladder logic (LL984). IEC 1131-3 compliant data types
are also available. With the data type editor, custom data types can be converted to
and from the IEC data types.
The basic elements of the FBD programming language are functions and function
blocks that can be combined to create a logical unit. The same basic elements are
used in the LD programming language; additionally, LD provides contact and coil
elements. The SFC programming language uses basic step, transition, connection,
branch, join and jump elements. The IL and ST text programming languages use
instructions, expressions, and key words. The LL984 programming language uses
an instruction set and contact and coil elements.
You can write your control program in logical segments. A segment can be a functional
unit, such as conveyor belt control. Only one programming language is used within a
given segment. You build the control program, which the automation device uses to
control the process, by combining segments within one program. Within the program,
IEC segments (written in FBD, LD, SFC, IL and ST) can be merged. The LL984
segments are always processed as a block by the IEC segments. Concept's
sophisticated user interface uses windows and menus for easy navigation.
Commands can be selected and executed quickly and easily using a mouse.
Context-sensitive help is available at each editing step.
Variables for linking basic objects within one section are not required by the graphic
programming languages (FBD, LD, SFC and LL984) since these links are created by
connections. These connections are managed by the system, which eliminates any
configuration effort. Other variables, such as variables for data transfers between
different sections, are configured with the variables editor. With the data type editor,
custom data types can be derived from existing data types.
