Post by ellocco on XOR with four Inputs with OR-, NON- and AND-Operators ^{CODESYS Forge talk (Post)}
My topic is more of academic nature, I would like to implement an XOR-operation with four inputs on my own (without the predefined XOR-operator) in a function block diagram (FBD). I have two proposals. One works fine and the other one is just an idea, but I do not know, if it is possible to code it in CODESYS V3.5 SP18 in form of a FBD. Here the one that works: And here an idea, which I have not managed to code it as an FBD: Any ideas? Is the 2nd diagram a correct interpretation of the coding task? And is there a way to implement it in form of an FBD in CODESYS V3.5 SP18? Followup (08-Nov-2024): Also in the current version of CODESYS (V3.5SP20Patch3) I have not managed to connect the existing blocks. In the alternative SPS-IDE PLCnext Engineer it is possible.

Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Hi, I struggle with exporting my Alarm Messages and following importing back to my project. Because filling in one by one is very time consuming I want to use export function and edit .csv file in Excel. As soon as I modify the file the import back to project does not work at all and function returns errors. Would you pls give me a hint how to properly use this functionality? Thanks a lot for help. Regards, M.

Post by tvm on multiply gives negatives ^{CODESYS Forge talk (Post)}
It's probably because you have an INT in the input to the MUL function, which will then try to output an INT as well. INT variables can only handle values of -32768 to 32767. Your value of 523000 won't fit in an INT, so it turns into an invalid number. Use a DINT. This is usually better for working with time values anyway, because time values are all 32 bit. Or if you can't, use INT_TO_DINT(gvlp.detectie_nalooptijd_s) in the input to the MUL function.

Post by aniket-b on Multiple function blocks are not executing at the same time in ladder logic ^{CODESYS Forge talk (Post)}
I have two ethernet Ip drives and created Function Blocks for different motions tasks. I am using same FB for both the drives. When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

I'm installed the CODESYS Control for Linux SL package and am trying to use the Extension API to call a simple C function. When I get to the step to run "make all" on the Linux machine, I get the error: build interface header: out/CmpFirstTestItf.h from CmpFirstTestItf.m4 ERROR: This functionname does not contain _cext (this is mandatory, see help for details): DEF_API(void',CDECL',external_struct__fb_init',(external_struct_fb_init_struct *p)',1,0x1F77E075,0x00000001) Why does "Generate Runtime System Files" create a function that does not have cext in the name? What am I missing?

Post by shawn-plc on Return value from a tag given a string literal ^{CODESYS Forge talk (Post)}
Good afternoon everyone, I am looking for a way to return a value given a string tag path. I put together a pseudo-example to illustrate my use-case and was wondering if anyone in this forum can help. The function fnValueFromTagPath is the function I am looking to either create or use from existing library. I would greatly appreciate it. Please see the attachment for additional detail. -Shawn

Just verified the behaviour. Still is the same. It should be attached here. But I also tried the DCF-file with the axis in the lab with the real drive: The MC_Power block never goes out of busy. Had not time to investigate further, though.

Hi @eschwellinger Just wondering if there is any update when the Expression or part of it has no effect will be fixed? Also have the ability to open an FB when online and offline. It would also be great to be able to view the ST code block when online.

Post by timvh on Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden ^{CODESYS Forge talk (Post)}
If you are really happy with PLCnext engineer, then just use that. There is probably also something in CODESYS that cannot be done in PLCnext engineer. But if you are forced to make something like this in CODESYS, then maybe just use CFC instead of FBD.

Post by timvh on Detect "Cancel" Press in FileOpenSave Dialog ^{CODESYS Forge talk (Post)}
Maybe there is a better way, but a long time ago I created a test application that worked like this: With a button I opened the dialog and I added a "Input configuration - OnDialogClosed" "Execute ST-Code" action to this same button which called the following Function when the dialog was closed: F_OnFileDialogClosed(pClientData); Below this Function which handled the result: // This function is called from the visualization when the dialog is closed. FUNCTION F_OnFileDialogClosed : BOOL VAR_INPUT pClientData : POINTER TO VisuElems.VisuStructClientData; END_VAR VAR dialogMan : VisuElems.IDialogManager; FileOpenCloseDialog : VisuElems.IVisualisationDialog; result : VisuElems.Visu_DialogResult; _sFileName : STRING(255); END_VAR // the DialogManager is provided via the implicitly available VisuManager dialogMan := VisuElems.g_VisuManager.GetDialogManager(); IF dialogMan <> 0 AND pClientData <> 0 THEN FileOpenCloseDialog := dialogMan.GetDialog('VisuDialogs.FileOpenSave'); // gets the FileOpenSave dialog IF FileOpenCloseDialog <> 0 THEN result := FileOpenCloseDialog.GetResult(); // gets the result (OK, Cancel) of the dialog IF result = VisuElems.Visu_DialogResult.OK THEN // Original code gvlFile.FileListProvider(); _sFileName := CONCAT(gvlFile.FileListProvider._stDirectory, gvlFile.FileListProvider.stFile); // do something with this file name...

okay but will this pass the array by copying it or it will be a reference to original array only.
