Parameters, which were previously transferred to the class factory, determine which sort of reference is generated. Fault insertion test requirements.
In this way, the new class factory obtains the GetLogger method. Two parameters define the user name and the password, while the third one contains connection data for the database. This block implements the interface ILogger and consequently the Write method. HW classification of faults. This method returns the interface ILoggerbehind which the Write method of the actual logger is located.
FS-PLC operation, maintenance and modification procedures. Management of functional safety. This path defines in which file the messages are saved. Example 3 TwinCAT 3. A function block for logging is created.
The term class factory denotes an object in object-oriented programming, 611316 generates other objects. The implementation of the new function blocks is very simple: Conformance to this standard. 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.
The result is a function block, which covers all 6113-16 cases internally. The dynamically created function block is assigned to the variable ipLogger in lines 14, 17 and In this way, an abstract function block can be compared with an interface. Thus, a strong dependency exists between these function blocks. You are commenting using your Facebook account.

HW functional safety requirements specification. This is possible, because the dependencies of the function blocks between themselves were changed. In this way, each variant has its own function block which contains the Write method. HW design, development and validation planning.

Example 2 TwinCAT 3. Write ‘Hello’ ; However, the block becomes bigger with each memory type and occupies space in the program memory.
As an example, a small PLC library for message logging is created. To find out more, including how to control cookies, see here: It means that the original functionality of a module can be changed through the usage of the extension modules.
FS-PLC design, development and 6113-6 plan.

Thus, functionality is added to the function block through this reference. Notify me of new comments via email. An abstract class factory allows the user to adjust the library range of functions without changing the sources. The user determines which specific class factory to apply only when using blocks, i.
Instance of the function block are created at run-time as well. However, the block becomes bigger with each memory type and occupies space in the program memory. Sorry, your blog cannot share posts by email. Notify me of new posts via email. IEC english Tags: The objective of this part is:
