Post by vsgn on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
Hi, in my experience, the best options for such a case could be: 1. Pass a FunctionBlock via VAR_IN_OUT, containing all variables, mehods and properties needed for the logic of this graphic element (be aware of implementing correcly both get and set accessor for properties) 2. Pass an Interface via VAR_INPUT, of which you can use obviously only Properties and Methods. This is much more elegant for me. Here, you can just pass directly the instance of a FunctionBlock implementing such Interface as input. Hope you'll find this suggestions useful.

Post by eschwellinger on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
I would recommend to ask Moxa for a newer version of Debian. Debian 9 ("Stretch") has reached its end of life and is no longer receiving security updates from the official Debian Security Team as of June 30, 2022. This means any systems still running Debian 9 are vulnerable to security risks and should be upgraded to a newer, supported version of Debian like Debian 10 ("Buster") or Debian 11 ("Bullseye").

Post by bmatlove on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
I'm trying to firm up alarming of axis faults. Declutter the code and figure out what's what. Diving into it, I see the AXIS_REF_SM3 function block provides uiDriveInterfaceError and dwErrorId, but I can't find any significance of these further than Drive interface error number Parameter number: 1014 and Drive specific error identifier, parameter number: 1031, respectively. Is there some corresponding appendix I could use to decode these? Also, is there any relation to the Error ID (of type SMC_Error) of the MC POUs? MC_Jog, MC_Reset, MC_MoveRelative, etc? If so, are the above errors redundant? Thanks in advance.

Just to share, for those who as me are seeking for this and had found no information anywhere in this World: Every time I stop/start the PLC runtime ( turning into 'Stopped' or 'Running' state ) the 'CODESYSControlService' appears at the Taskmanager list, which could suggest a straight correlation. I was expecting a clever solution, but this one solves for while.

Hello guys! https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_label.html My question: Could I give an integer variable to the Position records (in the Element list => Position => width / height)? If yes, how? I defined a TEST integer variable with 300 value. I tried to add this variable to the width record (.TEST or only TEST), but if I saved, the value jumps back to 0. Thanks for your help! :)

I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge talk (Post)}
In my machine's operation, I need to display multiples tables containing arrays of structured variables. The arrays change during operation, and my supervisor has advised me to write a new bubble-sort for each array. I think I can make a function to sort an array of any data type. This was my own project, and I'm a relatively new coder. I want to know the weaknesses in my approach, and a better method, if one exists. As far as I can test, the function accepts an array of a structured variable of any size, and sort it by any VAR in that structure. But it relies heavily on pointers, which I've heard are bad practice? Function call: // SORT BY BYTE-SIZED VAR IF xDoIt[6] THEN FUNBubbleSortSansBuffer( IN_pbySourcePointer := ADR(astArray[1]), // address of first byte in first element of array IN_pbyComparePointer:= ADR(astArray[1].byCompByte), // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize := SIZEOF(TYPE_STRUCTURE), // size, in bytes, of the structured variable IN_uiCompareSize := SIZEOF(astArray[1].byCompByte), // size, in bytes, of the comparing variable (variable you sort by) diArrayElements := UPPER_BOUND(astArray,1), // number of elements in array IN_xSmallToLarge := xSortOrder // whether to sort by small2large or large2small ); END_IF Function: FUNCTION FUNBubbleSortSansBuffer : BOOL VAR_INPUT IN_pbySourcePointer : POINTER TO BYTE; // points to beginning of array (first byte of first element) IN_pbyComparePointer: POINTER TO BYTE; // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize : UINT; // size, in bytes, of the structured variable IN_uiCompareSize : UINT; // size, in bytes, of the comparing variable (variable you sort by) diArrayElements : DINT; // number of elements in array IN_xSmallToLarge : BOOL; // whether to sort by small2large or large2small END_VAR VAR j : DINT; // repeat iteration over array until array ends i : DINT; // iterarte over array, swapping when necesary k : DINT; // iterator from 1 to size of structure (stepping 'through' a single element in array) dwSize : DWORD; // internal var for use in MEMUtils.MemCpy(<size>) // FOR SORTING BY BYTE VAR pbySourcePointer : POINTER TO BYTE; pbySourcePointer2 : POINTER TO BYTE; pbyComparePointer : POINTER TO BYTE; pbyComparePointer2 : POINTER TO BYTE; pbyPointerToBuffer : POINTER TO BYTE; // pointer to single byte buffer byBufferByte : BYTE; // single byte buffer END_VAR dwSize := UINT_TO_DWORD(IN_uiStructureSize); // get structure size (number of bytes) pbyPointerToBuffer := ADR(byBufferByte); // assign pointer to address of buffer byte (because MEMUtils.MemCpy requires a pointer input) CASE IN_uiCompareSize OF // depending on the size of the VAR to sort by (current functionality for BYTE and WORD/INT 1: // BYTE (8 BIT) FOR j := 1 TO diArrayElements DO // for number of elements in array FOR i := 1 TO (diArrayElements-1) DO // same thing, but row[i+1] row is included in swap logic pbySourcePointer := IN_pbySourcePointer + dwSize*(i-1); // point at #1 byte in array element[i] pbySourcePointer2 := pbySourcePointer + dwSize; // point at #1 byte in array element[i+1] // NOTE: because of memory locations, each array element is offset from one another by a number of bytes equal to the size of the structure // We can "walk" from array[i] to array[i+1] via steps equal to the size of the structure // e.g., ADR(array[i+1]) == ADR(array[i]) + SIZEOF([array datatype]) pbyComparePointer := IN_pbyComparePointer + dwSize*(i-1); // point to sorting variable in array element[i] pbyComparePointer2 := pbyComparePointer + dwSize; // point to sorting variable in array element[i+1] // using sort order (small -> large/large -> small) IF SEL(IN_xSmallToLarge, (pbyComparePointer2^ > pbyComparePointer^),(pbyComparePointer2^ < pbyComparePointer^)) THEN // This is where it gets tricky. We've identified pointers for the starting bytes of aArray[i] and aArray[i+1] // and we know the size of aArray[i]. We are going to swap individual bytes, one at a time, from aArray[i] and aArray[i+1] // this allows us to use only a single byte var as a buffer or temporary data storage // e.g., consider a structure consisting of a word, a byte, and a string. it is stored like this // |------WORD-------| |--BYTE-| |STRING------...| // astArray[1] == 1000 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 0001 0010 0100 1000 0011 1100 0101 0101.... etc // performing a single swap (copy into a buffer, etc.) of the first byte of each array element creates this // astArray[1] == 0001 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0010 0100 1000 0011 1100 0101 0101.... etc // incrementing the pointer adresses for the swap by 1 and swapping again swaps the next byte in each array element // astArray[1] == 0001 0010 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0100 0100 1000 0011 1100 0101 0101.... etc // continuing this from k to SIZEOF(TYPE_STRUCTURE) results in a toally swapped row FOR k := 1 TO IN_uiStructureSize DO // copy single byte[k] of array element 1 to buffer MEMUtils.MemCpy(pbyDest := (pbyPointerToBuffer), pbySrc := (pbySourcePointer+k-1), dwSize := 1); // copy single byte[k] of array element 2 to 1 MEMUtils.MemCpy(pbyDest := pbySourcePointer+k-1, pbySrc := (pbySourcePointer2+k-1), dwSize := 1); // copy buffer to byte[k] array element 2 MEMUtils.MemCpy(pbyDest := (pbySourcePointer2+k-1), pbySrc := pbyPointerToBuffer, dwSize := 1); END_FOR END_IF END_FOR END_FOR
