For modern machine manufacturing, clearly constructed and modular software is an essential factor for success. ALL-IN-ONE Modularity and reusability are cornerstones for efficient and flexible application development. These properties allow you to quickly program and configure customer-specific machine software. The object-oriented engineering suite LASAL from SIGMATEK provides you with exactly this simple reusability of modularly constructed application code and the flexibility that comes with it. LASAL unifies all automation tasks on one platform and contributes to significantly reduce development...

ENGINEERING TOOL LASAL ONE TOOL FOR ALL AUTOMATION TASKS Object-oriented programming with graphic representation The modern, consistent engineering environment expands the IEC 61131-3 standard with object-oriented programming (OOP) and graphic representation. LASAL enables the modularization of machine functions in the software and therewith mechatronic engineering. In mechanics, proven constructions are often reused. Thanks to the modular structure of OOP, existing and tested application modules can also be easily reused. The software machine functions (objects) can be assembled in a toolkit...

HOT FACTS CONSISTENT DEVELOPMENT All automation tasks unified in one software environment MODULAR OBJECTS that can be flexibly applied and reused CLARITY via graphic representation and efficient extras like the Machine Manager SUSTAINABLE CODE CLEARLY AND QUICKLY TO THE APPLICATIONS SOFTWARE Graphic representation of the software components in LASAL encapsulates the complexity of the project and enables clear structuring of the software. Application Modules Ready-to-use The motto is "Program less – just configure". In extensive libraries, tested function components (classes) are available. In...

LASAL CLASS PROGRAM CONTROLS WITH OBJECT ORIENTATION With LASAL CLASS, object-oriented programming is child's play. A consistent operating concept, graphic representation and ready-to-use function modules bring you quickly to your goal – whether the control task is simple or complex. With LASAL, user-friendliness is the focal point. You should be able to use the advantages of object-oriented programming, such as modularity and simple reusability, without having to come into contact with the complex syntax. The code reads like conventional structured text and you can therefore concentrate on the...

INHERITANCE AND AGGREGATION MINIMIZE PROGRAMMING Using inheritance, an object class can be duplicated and refined or specialized. Inheritance describes a relationship between a general class (base class) and a derived class. A derived class inherits the properties of the base class, but can be modified or expanded with additional information such as attributes or operations. Through aggregation (grouping), individual classes can be combined into a complex class. Tested classes can be clearly stored in libraries and combined into complex program structures using the toolkit principle. The communication...

CONVEYOR BELT UNIT CLASS MOTOR CLASS CONVEYOR CLASS CYLINDER CLASS Example Transport route for goods with three sequential conveyor belts: each conveyor belt is driven by a motor, which has start and stop conditions and a cylinder at the end that pushes the package further. Three classes are therefore modeled: motor and cylinder control, as well as conveyor belt (start/stop conditions). Through aggregation (grouping), a complex class "Conveyor Belt Unit" can be created from these three classes. OOP INSIDE With the techniques "inheritance", "derivation" and "aggregation", it is possible to implement...

OBJECT-ORIENTED INSTEAD OF PROCEDURAL In pure procedural programming, data or variables are managed separately from code. The missing definition, such as how the interaction between code and data is processed can lead to defective programs. PROCEDURAL Methods (Behavior) Data (Properties) Interfaces With object-oriented programming (OOP), code and data are combined into logical units and shielded from the outside world, so that unwanted influences are prevented. OBJECT-ORIENTED Objects Methods (Behavior) Data (Properties) Interfaces What advantage does encapsulation bring? Every programmer knows...

Clear: the objects and their relationships are graphically displayed in the object network. PROJECT TREE NETWORK EDITOR VARIABLE PROPERTIES OF THE SELECTED ELEMENT USER INFORMATION, WARNING AND ERROR MESSAGE application is generated. LASAL CLASS creates all declarations and function bodies automatically. As a user, you must only program the individual methods, without having to worry about the declaration syntax. Through graphic representation, you get a complete overview of the project at a glance: the functions, the relation between objects, the data traffic and the interfaces. Complex relationships...

OBJECT-ORIENTED PROGRAMMING IN FAMILIAR LANGUAGES With LASAL, the actual program code of an object is implemented in the conventional program languages: structured text (ST), ladder diagram (LD), graphic sequential function chart (SFC) and instruction list (IL) – all four in compliance with the IEC 61131-3 norm – as well as ANSI-C and interpreter. The object-oriented programming methods are therefore available as an integrated extension of the trusted languages. LASAL Supports Matlab Simulink In Matlab Simulink, existing C code models can be directly inserted into LASAL. During import into the...

KGKrSffla* 5«JW [Km OC^dew M S*M3 iJt<AS The graphical hardware editor provides great clarity for project development. The hardware editor is a comfortable tool, which significantly reduces the development and programming time of applications. In addition to the tree display, it is also possible in the graphical editor to reproduce the hardware components analogous to the real control cabinet configuration. This enables simple and efficient Finding and inserting a module is comfortably solved in the hardware editor. Possible control configurations can be run realistically. While comparing the...
