Post by trusty-squire on CNC - How to manipulate SMC_GeoInfo objects ^{CODESYS Forge talk (Post)}
Sometimes you just need to pose a question on a forum and re-read it to get clarity. pGeoInfo := SMC_GetObj(poq:=ADR(fbCncInterpreter.poqDataOut), n:=1); This won't work, I'm providing a pointer to a pointer, as poqDataOut is already a pointer! I just need to remove the ADR() and it works. pGeoInfo := SMC_GetObj(poq:=fbCncInterpreter.poqDataOut, n:=1);

I'm not really sure what you are trying to do, but maybe you are referring to using the CmpCharDevice library? When you "open" the connection to a device, you can pass flags. What helped me is to set the non-blocking flag. I'm not sure if this is what you are referring to, but maybe it helps: dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice := CmpCharDevice.CDOpen(szFilename, dFlags, Result);

Post by abinvest579 on COP instruction ^{CODESYS Forge talk (Post)}
Hi All, I have hands on rockwell software like rslogix 5000 and studio 5000. Currently started working on codesys i want to know is there any COP instruction with similar functionality in codesys like rockwell. I want to use it to split REAL into 2 INT,DINT to 2 INT also reverse 2 INT into DINT and 2 INT into REAL. Thanks in advance

First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Post by mxj262 on FB having single input but initialized with Array ^{CODESYS Forge talk (Post)}
I am adding elements of an ARRAY using pointer to access each element inside a FOR loop and the FOR loop does not stop! What is the right way to use pointers in such case?? I have another loop that is not using pointer and it stops but the loop using pointer keep on adding. METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: the retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR_IN_OUT // basically REFERENCE TO window_buffer: ARRAY [*] OF INT; // array of any size END_VAR THIS^.windowPtr := ADR(window_buffer[0]); THIS^.windowSize := UPPER_BOUND(window_buffer, 1) - LOWER_BOUND(window_buffer, 1) + 1; FUNCTION_BLOCK FB500 VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR windowPtr: POINTER TO INT; windowSize: DINT; currentIndex: UINT; element1:INT; element2:INT; i:INT; j:INT; sum:DINT:=0; END_VAR element1:=windowPtr[0]; // read the first element of the Array dynamic memorry element2:=windowPtr[1]; FOR i:=0 TO (TO_INT(windowSize-1)) BY 1 DO // this loop does not stop Sum:=sum + windowPtr[i]; END_FOR FOR j:=0 TO 5 BY 1 DO // this loop stops j:=j+1; END_FOR https://ibb.co/k3DhkZT
