Hi TimH Thanks for the information, I thought that was the case so have stepped through the code and found an error that wasn't closing the port, therefore hCom was increasing. Thanks

Hi francoinf, I've the similar problem and similar configuration. I did with an Arduino Board loaded by a ModbusRTUServer application on it. What I've notice is the slowly acquisition when release the digital signal (e.g. pin2) when it gets off. Anyone have suggestion?! Thanks

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

Hi! I tried to start Codesys V3.5 SP11 program and this error message popped up (see attachment). Program worked fine last week. I tried to uninstall and then reinstall the program but it did not help. If I choose Ignore or Retry options the program works expect the UI is missing. Any ideas how to fix this?

Post by gseidel on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi bertus, thanks for the additional information. Setting bAbort on a restart is not needed. Calling all FBs starting from the decoder up to checkvelocities with bExecute = FALSE and then giving a new rising edge on bExecute is what should be done. Do you also restart the Interpolator? (I don't think that has anything to do with the issue, but still...) Best regards, Georg

Post by malie on Issue with library updates ^{CODESYS Forge talk (Post)}
I just tried with version 3.5.22.1 and librarys updates often aren't recognized, usually not. Same behavior like 3.5.21. To describe my workflow: one IDE is used to test librarys as project and two or more IDEs to edit librarys. With only two open IDEs there is no problem, the problem began with more than two open IDEs.

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 tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Post by timvh on Colors look different when logged in and running ^{CODESYS Forge talk (Post)}
At the top of the Visualisation Properties View, you can enable the "Advanced" options. This will give you access to more properties than what you currently see. There might be a variable linked to the "advanced" colour property where the fill colour is determined by the value of this variable (dword).

Hello everyone, I was just wondering if anybody knows if there's a way to pull the string name of the current visualization without using the current visu variable. I'm working on a project where we don't want web clients to change the current visualization on the HMI of the machine. Thanks!!

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

I am trying to create a new proyect using the Raspberry Pi 4.11.0.0 package with Codesys 3.5 SP20, I am able to communicate with the Raspberry and start the runtime application but when I create a new proyect I have these errors. When opening the library manager of the proyect the library of the IoDrvGPIO is used so I dont really know whats happening.

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!
