Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
I see, you want to initialize the FB. To be able to initialise it like you described, you need to add the FB_Init method to your FB. (right click on the FB, select add object --> method). Then press the arrow down, to select the FB_Init (overwrite default implementation). In the VAR_INPUT section of this method, add the variable --> Tag : STRING; Then in the code section of this method add: THIS^.Tag := Tag; // copy initial value to local variable in FB Search Google if you want to know more about FB_Init. PS, reflection + instance path, is also an option if you want to get the full name of the instance (path) of the Function Block. See: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_instance_path.html

Post by fless on See only variable ^{CODESYS Forge talk (Post)}
either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.

Post by struccc on HTML5 Controls - string(>80) values ^{CODESYS Forge talk (Post)}
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

There appears to be a limit to the number of OPC Servers that can be connected simultaenously. 1-10 work but adding an 11th makes one of the previously linked ones unavailable. Is this a soft setting that can be adjusted? Using 3.5.18.30 on Win x64

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, thanks for the link. Maybe I create elements in incorrect way. I always use Interface Editor to create variables which are used inside element (see pics). After that I place element in my visu and use Reference property to link variable or set the value. In that case the value of string is not transferred to general text list for translation as I mentioned before. Do I have to all properties which influence behavior of my element create in Frame configuration instead? What´s the difference to the Interface editor? Thanks a lot. M.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

Post by installwhat on raspistepper error after install ^{CODESYS Forge talk (Post)}
from another post on this forum .... In your library project select Project -> Project Information. On the Properties table remove the "LanguageModelAttribute" Value "Qualified Access Only". This will allow you to access the object without qualifying the access. ...... I guess they've compiled it the library with that setting and now I need to mess around with versions.

Post by durallymax on Access Variable Visu Dialog ^{CODESYS Forge talk (Post)}
Is there a way to access the variable in the called dialog? Example: Text Field element with PLC_PRG.myVar as Text variable. OnMouseClick configured to write variable with keypad pop-up. OnValueChanged configured to Execute ST RND(PLC_PRG.myVar,2); Rather than change myVar with each copy of this Text Field, is there a way to access whatever the configured text variable is? Generally try to stay away from ST in visu, but was curious regardless.
