Post by timvh on HTML5 visualization controls disabled on CODESYS Control for Linux SL - overlay not supported? ^{CODESYS Forge talk (Post)}
I was able to reproduce this by doing something wrong. I guess what you did is first create an application for the Control Win, or some other device and then switched this to the Linux SL. But then the Visualization Manager still has the "TargetVisu" component, besides the WebVisu component. The Linux SL doesn't support this TargetVisu as part of the runtime. You should run a separate process for this. So remove the TargetVisu from the Visualization Manager and then you will be able to load the application.

Hi, for Control Win : add CmpEL6751CanDrv in the c:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE\CODESYSControl.cfg [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=CmpEL6751CanDrv for Linux SL or Pi or any ARM device - I think it is already static loaded as component - see plclogger on startup

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

It seems that there is a limitation with the STRUCTs. Does anybody know, what’s okay to save (add to the recipe) and what’s not okay? Or is there another problem with my project? If I have only an array in the recipe definition everything works perfectly (see project).

Is there a variable indicating that a gearing or camming operation is pending? For instance MC_Gearin has beeen triggered, but starting point of master axis to start the sychronisation movement is not reached yet, so the slave axis is just waiting for this. I should be able to differ between a pending and active gearing or camming

After installing this new 4.12.0.0 SL version on my RPi5 8GB and the latest bootloader, the runtime disappeared after 15secs. The bootloader my pi uses is from 2024-06-11. I was able to resolve this issue using this post: https://forge.codesys.com/forge/talk/Runtime/thread/be25c0ff66/ The workaround works for me.

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'

At the moment there are some changes on PI OS, which lead to problems with the PI5 an Pi runtime. I would use Arm SL or Arm 64 SL as runtime depending on which OS you have installed. just use the CODESYS Installer and deploy the the Arm runtime.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Yes, this is the error the sometimes show up. What make me crazy is the fact that it happens randomly and not each times. I know very well where the problem is, in wich one program row it's located. For each actions of the state machine I have all events recorded with log on text file. it is not problematic for me to find the application point of the fault, but I need to understand why occasionally and for no apparent reason, switching the state machine and thus changing the motion FB, sends the axis into failure (but only occasionally). For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hi, I suppose that you are referring to the error code "SMC_FB_WASNT_CALLED_DURING_MOTION"? Starting of Softmotion version 4.15.0.0 the instance path of the function block that has not been called is logged into the device log. This might help you to identify why it has not been called.

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

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);

Post by dkugler on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.
