Standards New Zealand :: Programmable controllers – Part 6: Functional safety

A function block with 16131-6 instantiation In this case, the concept of the dynamic memory management is helpful. Email required Address never made public. The dynamically created function block is assigned to the variable ipLogger in lines 14, 17 and Thus, the example contains four function blocks and one interface.

Properties of an application can hardly be expanded by this fixed assignment.

The file extension serves as an identifier of the file format in this case. PLCopen starts new working group on Industry 4. HW design and development. Since the class factory kec supplies the GetLogger method in this example, it is derived from an abstract base function block, which specifies this method.

In order to simplify an access to the Write method of the respective logger block, the interface ILogger is defined. Post was not sent – check your email addresses! As a consequence, it is not anymore necessary to create an instance of all possible function blocks statically. Comments 0 611131-6 0 Leave a comment Trackback. Techniques and measures to prevent the introduction of faults in ASICs. Threading 3 Task Parallel Library 6.

This part is a product specific implementation of the requirements of the IEC series and conformity to this part fulfils all of the applicable requirements of the IEC series related to FS-PLCs. One of these principles is Open Closed Priciple, i.

Variant 1: A simple function block

Example 1 TwinCAT 3. In this case, a function block is defined the actual class factorywhich provides jec reference to another function block through a method. ASIC design and development. The term class factory denotes an object in object-oriented programming, which generates other objects.

HW safety validation planning. Example 2 TwinCAT 3. Here is the iwc of the single POUs: This is possible, because all function blocks implement the interface ILogger. A class factory can help to break these stiff structures.

To find out more, including how to control cookies, see here: At the same time, the extension modules contain only the adjustments of the original 6131-6. In the Write method, an IF statement distinguishes different variants and calls the compatible private method respectively.

Information on type and content of documentation.

In this way, the new class factory obtains the GetLogger method. If instances of a function block have to be created, the exact type of the function block should be known before compiling. Open Closed Principle Object-oriented programming defines several so-called ic. SW safety validation planning. A factory can be implemented in different ways. In this example, on startup of the application.
