Hi, yes now its working, to get "QUEUE.bFull" to work, I've had to set the "QUEUE.nNumReservedEntries" to 3. (I tried different values here, only effect for larger values i can see is the the queue capacity gets smaller.) I've noticed the movement is slowing down when it reaches the end of the "fill Up", must be because of the "checkVelocity" can only see the current "QUEUE". Any way of solving this ? BUF : ARRAY[0..20000] OF SMC_GEOINFO; xp : ARRAY[1..100000] OF REAL; yp : ARRAY[1..100000] OF REAL; CASE iState OF 000: IF R_TRIG_bStart.Q THEN iState := iState + 1; END_IF bReady := FALSE; //initialize Queue GEO.dT1:=0; GEO.dT2:=1; GEO.dToolRadius := 0; GEO.dVel := 15000; GEO.dVelEnd := 15000; GEO.dAccel := 2000; GEO.dDecel := 2000; GEO.iObjNo := 0; GEO.piDestPos.dX := 0; GEO.piDestPos.dY := 0; QUEUE.bEndOfList := FALSE; QUEUE.nPastMarker := -1; QUEUE.nWritePos := 0; QUEUE.pbyBuffer := ADR(BUF[0]); n := 0; sMC_CheckVelocities(bExecute:= FALSE); SM3_CNC.SMC_SetQueueCapacity(ADR(QUEUE), SIZEOF(BUF)); QUEUE.nNumReservedEntries := 3; 001: FOR i := 1 TO SIZEOF(xp)/SIZEOF(xp[1]) DO xp[i] := UDINT_TO_REAL(i) * 0.01; yp[i] := UDINT_TO_REAL(i) * 0.01; END_FOR iState := iState + 1; 002: WHILE NOT QUEUE.bFull DO // when the Queue is full, wait until it has been processed by the following FBs n := n + 1; GEO.iSourceLine_No := n; GEO.piStartPos := GEO.piDestPos; // copy last destination GEO.iMoveType := LIN; // generate linear movement GEO.iObjNo := GEO.iObjNo + 1; // calculate number GEO.piDestPos.dX := xp[n]; // generate position GEO.piDestPos.dY := yp[n]; SMC_CalcLengthGeo(pg := ADR(GEO)); // calculate length of object with the help of the standard function SMC_AppendObj(poq:=ADR(QUEUE), pgi:=ADR(GEO)); //append object to queue IF n = UDINT_TO_DINT( SIZEOF(xp)/SIZEOF(xp[1])) THEN // all target positions processed QUEUE.bEndOfList := TRUE; iState := iState + 1; EXIT; END_IF END_WHILE sMC_CheckVelocities(bExecute:= TRUE, poqDataIn:= ADR(QUEUE)); bReady := TRUE; // Send message to smc_interpolator to start 003:

Post by jeindhoven on Deploying to raspberry pi 5 hangs ^{CODESYS Forge talk (Post)}
Yep sure, though now that i think of it, its a pi 4. My bad. The whole ordeal was necessary to use the VGA666 adapter. That needs the old graphical system and GPIO directly on the CPU. Edit: Putty on the virtual development machine connects fine. But i did change the login/pw. The account is still a sudo'er so that should be all right. Edit2: Sorry i get a "Comment rate limit exceeded" from the forum. Then i'll add it as edit here. So i have tried the stock raspberry pi image on a different pi5 (truly 5 this time). Packages updated. Standard password. Same symptoms, no runtime deployed and long hang time. Versions of this pi: pi@raspberrypi:~ $ uname -a Linux raspberrypi 6.12.25+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.25-1+rpt1 (2025-04-30) aarch64 GNU/Linux pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm pi@raspberrypi:~ $ apt list --installed | grep openssh-server openssh-server/stable,now 1:9.2p1-2+deb12u6 arm64 [installed,automatic] Attached is the Device information and error text that Codesys comes up with. Edit 3 (Comment rate limit, otherwise it would be a new post) Now i have tried booting an older native Windows 10 machine (no virtualization), and it just works as expected. I have now a raspberry pi 4 and raspberry pi 5 with version 4.16.0.0 of the control application. Windows 10 native: build 19045 (same as virtualised Win 10), same .NET version, same CODESYS version. It seems that running CODESYS virtualized somehow messes with the deployment?

Post by paulpotat on Where can I find a list of all available runtime configuration parameters ? ^{CODESYS Forge talk (Post)}
Hello, I was wondering if there is a list somewhere of all the parameters that can be used inside the "/etc/codesyscontrol/CODESYSControl_User.cfg" configuration file ? I searched the documentation but didn't find anything. If it doesn't exist, that would be nice to have a little bit more documentation about this file :) Thank you for your help, BR

Good day, I am attempting to use a Waveshare AD/DA precision HAT with RPi 4B+, using Codesys Control for Rpi. The waveshare hat uses SPI. I am successfully using the RPi GPIO (inputs and outputs) but do not know how to access the AD/DA channels. Any help would be appreciated.

Post by sandro66 on Application-based license Modbus Channels ^{CODESYS Forge talk (Post)}
Hi, I imported an old project created with version 3.51.20.50 into the new version 3.51.21.20. I'm using ModbusFB.ClientTCP v4.5.0.0. Strangely, I can no longer download the project due to a licensing issue I didn't have before. The number of Modbus channels has gone from 1 to 54!, and there's no license that would work. Can anyone tell me where I'm going wrong? Thanks Sandro

Post by gseidel on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hi kporter, a more direct way would be to use SMC_FollowPosition to write the set positions directly to the servo drive. This FB has reacts on changes of the fSetPosition on each call, without a need for a rising edge on Execute. See https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html. Best regards, Georg

I tried both 3B en 4. But every time with a lite version. I didn't try the full version of raspberry pi os. Nice to hear you are aware of the problem and trying to fix it. I'll hold on to the image from 2023-10-10 for now.

Hi! I'm still on the hunt for drivers for example TCA9548 and a list or somewhere where all devices for raspberry is gathered. as this post is quite old I'm hoping/gussing that there is somewhere where work after 2021 is gathered? Or has the raspberry part if the community slowed down on creating device drivers?

So none of the images from the 64bit archive work with any Codesys Control versions? I have tried the last Pi OS with every Codesys Control version and they don't work. I was wondering if there's any stable combination of versions.

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Hello, Has anyone tried running CODESYS Linux on Ubuntu Core? I'm having problems installing the runtime. The connection to UC cannot be established. I used the instruction: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_linux_public_key_authentification.html I can connect to UC using SSH (putty, shell). Codesys can't. Do any of you have an idea?

Hello, I think you can try to change the Connection from Multicast to Point to Point. Please also make sure your windows firewall is allowing the correct UDP ports inbound for ethernet IP. You might also need to increase the RPI, so it times out slower.

Post by timvh on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
Probably best to call the FB continuously. So something like this could solve it: IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog := FALSE; fbOpenLatchSettingsDialog.xExecute := TRUE; END_IF IF fbOpenLatchSettingsDialog.xDone OR fbOpenLatchSettingsDialog.xError THEN fbOpenLatchSettingsDialog.xExecute := FALSE; END_IF TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog( itfClientFilter:= VU.Globals.OnlyTargetVisu, sDialogName:= 'visu_AlarmLatchSettings', xModal:= TRUE, pTopLeftPosition:= ADR(TopLeftDialog) );

Call 10 FB instances. Connect Motor_1_Fault to the i_xHW_FaultDetected pin of FB 1, Motor_2_Fault to FB 2... By doing this, your FB will be flexible. The programming will be smooth like a perfect Drift Boss, instead of "hitting the wall" because it can't be reused!

Hello, Basically, everything is clear to me. There's still the issue of a TimeProvider for an external device. This may be a stupid question, but I can't find this package. And of course, the question is, can the RPi machine be an external provider? Has anyone tested such a solution?
