Introduction
Introduction
Concept
™
software is a conguration and application programming tool for the
Modicon
™
Quantum
™
and Modicon
™
Momentum
™
automation platforms. It is
Windows
™
-based software that can be run on a standard PC. The conguration task
can be carried out online (with the PC connected to the Quantum processor) or
ofine (PC only). Concept supports the conguration by recommending only
permissible combinations. During online operation, the congured hardware is
checked immediately for validity, and illegal statements are rejected.
Concept editors support ve IEC programming languages:
b
Function Block Diagram (FBD) language
b Ladder (LD)
b Sequential Function Chart (SFC) and Grafcet language
b Instruction List (IL)
b
Structured Text (ST)
Also supported is ladder logic (LL984) that is compatible with Modsoft
™
. IEC 61131-3
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; LD provides contact and coil elements.
The Grafcet SFC programming language (SFC) 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.
Programs can be written 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.
PLC conguration
Variables for linking basic objects within one section are not required by the graphic
programming languages (FBD, LD, SFC and LL984).
These wiring diagrams are managed by the system, which minimizes any
conguration effort. Other variables, such as variables for data transfers between
different sections, are congured with the variables editor. With the data type editor,
custom data types can be derived from existing data types.
