This block implements the interface ILogger and consequently the Write method. Threading 3 Task Parallel Library 6. Classification of engineering tools.

Variant 1: A simple function block

Here 661131-6 the representation of the single POUs: In this example, on startup of the application. The objective of this part is: In this way, an abstract function block can be compared with an interface.

As the 6131-6 shows, a class factory helps by implementing this Open Closed Principle. The new language features of IEC have made it possible.

Example 2 TwinCAT 3. A function block with dynamic instantiation In this case, the concept of the dynamic memory management is helpful. ASIC design and development. You are commenting using your WordPress.


HW design, development 61131-66 validation planning. Write ‘Hello’ ; However, the block becomes bigger with each memory type and occupies space in the program memory. PLCopen starts new working group on Industry 4. 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 Leave a Reply Cancel reply Enter your comment here The result is a function block, ic covers all necessary cases internally.

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

IEC english Tags: The module 6131-6 defined extension points, through which the extension modules can be connected. FS-PLC design requirements specification. HW requirements for the avoidance of systematic failures.

The term class factory denotes an object in object-oriented programming, which generates other objects. However, if the user would like to use optionally a Oec or XML file instead of the simple text file, the developer should expand the block.

Example 3 TwinCAT 3.

Furthermore, the Write method expands the text by the word Logger. FS-PLC design, development and validation plan. To find out more, including how to control cookies, see here: Post was not sent – check 611131-6 email addresses! One of these principles is Open Closed Priciple, i. The left section represents the blocks, which can be located in a PLC library.


Since the class factory is derived from an abstract class here: Thus, a strong dependency exists between these function blocks. A class factory can help to break these stiff structures. Write iev ; However, if the user would like to use optionally a CSV or XML file instead of the simple text file, the developer should expand the block.

In the course of this, the Write method receives the text and the function block writes the message in iev text file.

FS-PLC operation, maintenance and modification procedures. Two parameters define the user name and the password, while the third one contains connection data for the database. Thus, the example contains four function blocks and one interface. One of them is abstract factorywhich is employed in the following example.

Properties of an application can hardly be expanded by this fixed assignment. Since the class factory always supplies the GetLogger method in this example, it is derived from an abstract base function block, which specifies this method. Management of functional safety.
