Post by nathant on Running webvisu with Codesys Control Win V3 in Simulation Mode ^{CODESYS Forge talk (Post)}
Hello - I was wondering if I can run a webvisu in Codesys V3.5 SP 18 when using the Control Win V3 soft PLC. I don't see anything saying I can't do this, but I haven't been able to access the webvisu using conventional methods. Thanks.

Hi Ricardo. I was having the same problem with Codesys and a Raspberry Pi 2W while using the GPIO uart. Your post helped me a lot. Thanks! But could not understand why MODBUS parity bit makes Codesys MODBUS COM driver stopping to work after first request transmission. Did you see this @eschwellinger ? Regards, Nelson

Hi, same pb for me ! did you find a solution ? (I'm working on 2 raspberry pi ) The same project compiled for 4.8.0.0 runtime with CodeSys 3.5SP20 is working fine on one target, and on the other one, my UAexpert receives the same "BadIdentityTokenInvalid" and none is working on 4.11.0.0 either ... anybody ?

I made hardware reboot and it still not working. I also tried Persistence Manager which need Application Composer Single License but Codesys support said that my runtime do not compatibile with it and it will avaiable in 2025 only. So I hope I will figured out how to use this code.

Post by runtimevictor on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hello, In Codesys I can't find where to configure Ethercat Master VLAN tagging? In Beckhoff in Infosys there is an attached image so you can see it... I would like to try ethercat master with VLAN, to try to have several ethercat masters on a single ethernet port... I imagine that managed VLAN switches are also necessary? Thanks.

Post by gabor-n on PNIO Connect Parameter Error ^{CODESYS Forge talk (Post)}
It's a bit confusing, the two RPI is the same (board, OS, runtime, programing with Codesys V3.5 SP20 P2) but the one has a codesyscontrol.cfg file and the other has a codesyscontrol_user.cfg file. Shouldn't be the same? And because I over Codesys 3.5 SP 12 this would be the '_user.cfg' for both. Attached...

Post by eschwellinger on Scan Network on gateway created with Control Sl ^{CODESYS Forge talk (Post)}
it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

Post by daniel on SysFileOpen not working ^{CODESYS Forge talk (Post)}
Hello, I have the same problem now with 3.5.20 Patch 3. Normally it works if I ad in CODESYSControl.cfg: [SysFile] ForceIecFilePath=0 (This told me codesys last time) I try to use the placeholders but without success. Something special is that the Files are not in C:. The Plc Configuration Path is not as usual C:\ProgrammData\CODESYS\CODESYSControlRTEV3\, it's E:\Control.

If you are really happy with PLCnext engineer, then just use that. There is probably also something in CODESYS that cannot be done in PLCnext engineer. But if you are forced to make something like this in CODESYS, then maybe just use CFC instead of FBD.

Post by somlioy on CODESYS Control for PFC100 SL Firmware upgrade ^{CODESYS Forge talk (Post)}
Hi We delivered a system with a PFC100 using the CODESYS Control for PFC100 SL runtime a few years back. The system has once been decommissioned and are now to be commissioned again. Back then, there were only single licenses for the runtime. Can I now upgrade the firmware and runtime without purchasing a new license?

Post by yannickasselin on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have been running Codesys IDE in VirtualBox on a Linux Mint host for many many years without issues. I use it every day and it works great. I wouldn't mess around with wine. Would probably just be a waste of time. Codesys Go might be the future of PLC programming on Linux! Can't wait to test it.

Hello everyone. I am using Codesys and saw in a YouTube video on the Codesys channel (https://www.youtube.com/watch?v=y_l2siXY7dA) that you can create frames and move them with the mouse. However, the video does not show how to do this. Can someone please explain it to me? Thank you very much.

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

Post by timvh on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
If you want to use the Test Manager, I prefer to start all the tests through the scripts of this manager. So open from there the projects, load it and run it. If you also want to use Python scripts to access CODESYS functionality, while executing a Test Manager script, then also start them from the Test Manager commands.

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.

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

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

Hi Eschwellinger, sorry for so late reply but I found a solution back then; uninstall completely Codesys V3x64 and re-installed Codesys V3x32 to properly note the password I created and everything went ok. thank you for your suggestion and have a good day/evening Mike

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice
