I don't recommend using 'Communication Manager'. Under 'Communication Manager', the 'NodeId' type of OPC UA can only be of type 'OPAQUE'. This will bring compatibility issues to the development of the upper computer.
-
This seems to be because when creating 'OPC UA' with 'Communication Manager', the 'IdentifierType' of 'NodeId' cannot be configured as' String 'type. This issue is not an isolated case. For this issue, CODESYS seems to have not provided guidance to users on how to proceed. We can provide feedback on this issue in the 'My Question' section of the 'CODESYS Store' to make CODESYS take it seriously.

I have the same problem, it seems like there is no solution.

CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.
-
You should use this method: VAR NULL:REFERENCE TO FB_MSG END_VAR Add_EVT_OUT REF= NULL;

It seems that there is no solution to this problem.

Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.

Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Can you add a background FB block to the visualization page, and loop through this FB block when the page is in display mode. This FB block requires two more functions, one for executing when the page is displayed and the other for executing when the page is closed.
-
It's not that you missed something, it's that CODESYS doesn't have this feature. I hope CODESYS can add this feature. We also hope to add function overload functionality.
-
I have also been troubled by this issue for a long time, to the extent that I have to implement a recipe management library myself. Codesys version used: 3.5.19.40
-
I think what you want is a declaration period function for the page, but unfortunately CODESYS does not have it.

I have a project called 'DemoProject' and a library called 'DemoLib'. Create a visual control named "DemoVisu" in the library, with a selection box of type "ComboBoxInteger" in the space. Now 'ComboBoxInteger' requires a 'Text list'. This "Text list" is provided when I call the "DemoVisu" control of the "DemoLib" library in "DemoProject". And this text list is in 'DemoProject'. I found that 'ComboBoxInteger' no longer works at this time. Other visual controls that use text lists also have this issue....

Is this the library you created yourself? If so, please check if the attribute in the project information has this field 'LanguageModelAttribute'. If not, please add this attribute 'LanguageModelAttribute': 'qualified access only'.

Hahaha, with the rigorous attitude of Germans in handling affairs (which is a satire on Germans), it is strange that efficiency can be high. Go and see China, 996's work attitude will be completed quickly for you.

You can use datalog to save as CSV or SQLite.

How did they answer?
-
I'm looking for the same solution

If it is not a safety product, you can choose products made in China .

Oh. . . Create and die, this is the simplest life cycle function. Pages in a visualization should contain at least two functions, create and destroy. When we need to do some specific things in the life cycle of the page, such as specific display and specific notification when the page is converted, we need the help of the life cycle function.

Hello: As the title, how do I get or use the visualized lifecycle functions.

H: Obviously misunderstood the question. This is to better implement the contracted part of the HMSD(Hierarchical Master-Slave Distribution) framework. For example, batch initialization of states. For example: if you want to implement batch initialization of objects of class Step, you only need to pass the pointer of the first Step to the initialization function, and the function will automatically search down according to the first pointer until it finds an object that is not of the Step class and...
