Post by jrsantab on Remote connection to ifm PLC & HMI ^{CODESYS Forge talk (Post)}
We have finally solved the problem. The version of the Gateway in the computer that worked (3.5.11.0) and the one that didn't (3.5.17.30) was different. We have three different Codesys 3.5 versions installed because we work with different controllers. I believe that, depending on the sequence you follow to install the versions you get a different Gateway version. To solve the problem you first have to disable the "obsolete" services. Open services, serach for (in our case) CODESYS Gateway V3 Version 3.5.11.0 CODESYS ServiceControl Version 3.5.11.0 I stopped the services and changed to Manual Start. Then you have to create the new services. In our case, from a Command Prompt session (cmd): SC CREATE "Codesys GatewayService Rigual" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\GatewayService.exe" and then SC CREATE "CODESYS ServiceControl Version 3.5.17.30" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\CODESYSControlService.exe" remember also to set them as Automatic Start!

Post by kblundy on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
I hope the community can help me with this. I need to use the Visu Utils FbOpenDialog to control the opening and closing of a dialog. I have the Opening and Closing working, but I can’t get the dialogue's position to be controlled. The code looks like this: PROGRAM OPEN_DIALOG VAR xOpenLatchSettingDialog : BOOL; TopLeftDialog : VisuStructPoint ; fbOpenLatchSettingsDialog : VU.FbOpenDialog ; END_VAR IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog:= FALSE ; TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog(sDialogName := 'visu_AlarmLatchSettings', xExecute := xOpenLatchSettingDialog , xModal := TRUE, itfClientFilter := VU.Globals.OnlyTargetVisu, pTopLeftPosition := ADR(TopLeftDialog)); CloseVisuDialog(sDialogName:= 'visu_AlarmLatchSettings'); ELSE xOpenLatchSettingDialog:= TRUE ; IF fbOpenLatchSettingsDialog.xError THEN xOpenLatchSettingDialog := FALSE; END_IF END_IF I can't seem to work out a way to make the values in TopLeftDialog.iX and TopleftDialog.iY be passed correctly in the call and for it to change the position of the dialogue box. The code is compiled, but the position has not been changed. Any guidance or suggestions for revising this code would be incredibly valuable. Your insights could be the key to solving this issue.

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

Post by bertus on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi Georg, thanks for your time. What is the value of D_ANGLE_TOL? It is set to 0.01. Do you need the assignment bAbort := NOT bDecoder? Does it help to leave it out? This seems to make no difference. Any errors (e.g. SMC_SmoothPath.Error/ErrorID) or PLC log messages? No errors or log messages. What if you comment out SMC_SmoothMerge and SMC_LimtiDynamics, is corner smoothing still not working? Indeed. Is bDecode written from a different task (e.g. visu)? Then I would recommend to assign to a local variable (bDecodeLocal := bDecode) and use that for all FBs. Otherwise, FBs might see different values of bDecode in a single cycle, which will cause problems. It is a local variable, written from a state machine inside this program. But there is new information: During some trial and error, I tried skipping "stage 2: merge short linear segments" (SMC_SmoothMerge). And suddenly it rounds the corners, see attached image. Looking a bit closer, I noticed that (with the original program) after a download (cold start?), it in fact did round the corners, but only once. Ever next cycle in which the NC program was executed, the corners where not rounded. Not sure if there is any relation, but SMC_SmoothMerge is also the only FB which has no bAbort input. Perhaps I need to reset it (or any buffers) by other means?

Select in tree "DEVICE", right-click and select "Update Device" Select "Library manager" and Change the version of the Library (down manualy). Samoetimes "Try reload Library". If you open a project version 3.5.19 in version 3.5.16, there are difficulties.

You should use PLCnext if your device-hw is a PLCnext-un it. As I understand it you are using "CODESYS Control Win V3 x64".
