A factory can be implemented in different ways. Post was not sent – check your email addresses! The dynamically created function block is assigned to the variable ipLogger in lines 14, 17 and Open Closed Principle Object-oriented programming defines several so-called principles.

This part does not cover general safety requirements for an FS-PLC such as requirements related to electric shock and fire hazards specified in IEC The method can be expanded by its own parameters, which are forwarded as an instance lec declared. IEC english Tags: As the example shows, a class factory helps by implementing this Open Closed Principle.

The implementation of the new function blocks is very simple: Since the class factory is derived from an abstract class 61131–6 Classification of engineering tools. The term class factory denotes an object in object-oriented programming, which generates other objects.

A function block with dynamic instantiation In this case, the concept of the dynamic memory management is helpful. FS-PLC design, development and validation plan. In this way, each variant has its own function block which contains ie Write method. In this way, the new class factory obtains the GetLogger method. The objective of this part is: Fault insertion test requirements. As qualified versus as shipped.

ie By continuing to use this website, you agree to their use. HW design, development and validation planning. In order iwc simplify an access to the Write method of the respective logger block, the interface ILogger is defined.

A function block for logging is created. The user can specify the desired behaviour by the file name, when creating an instance. Parameters, which were previously transferred to the class factory, determine which sort of reference is generated. One of these principles is Open Closed Priciple, i. As a consequence, it is not ic necessary to create an instance of all possible function blocks statically.
