Post by sigurdrb on Codesys SP20 and professional developer edition ^{CODESYS Forge talk (Post)}
Hi, I updated codesys IDE to the newest version, but I lost the "professional developer edition" in the process. It still works fine on the older version I have been using previously. Do you know what the easiest process for getting the same integration in the newer version? It is only the GIT integration that I really miss.

HI I have had a project running for a few weeks and twice it has shut the program down due to this exception. exception[ProcessorLoadWatchdog] occurred in: App=[all], Task[all] I have to reboot (power cycle) the system to clear the exception. or remotely restart the application. Any ideas? Cheers

Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg

Hi, I've never used Communication Manager, but I tried it and I saw that I can drag tags from left to right. If I click on a line on the right, it turns light blue. By pressing the DEL or CANC key (It depends on your keyboard language) I can delete the line

Post by jeffersonhui on SP20 Visualization Element Dynamic Colors ^{CODESYS Forge talk (Post)}
I am using Codesys SP20 patch 5 and in a visualization element, the "Color variables" section does not have a section to set up dynamic color values linked to variables. In a previous version (SP18), I get the option to add variables for Normal & Alarm state colors. Does anyone know how to get the dynamic color variables to work?

Post by cellohorst on File Creation Issue ^{CODESYS Forge talk (Post)}
Nope! The file path is $$PlcLogic$$ and NOT $$PLCLogic$$. Otherwise a new folder ('PLCLogic') is created (at least with a linux rt - like raspberry or compute module) with the new file in it if you open the file with eFileMode := FILE.MODE.MRDWR. That is a bad bug that I'll report right after this comment.

Post by wayne-riesterer on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Thanks for your responses. I like to write the leanest possible code that I can because it makes it much easier to read/maintain/debug. OR_ELSE is what I was looking for. I wasn't sure if CodeSys short-circuited evaluation and I didn't realize this operator existed. Thanks!

I am using Codesys Control RTE V3 Version 3.5.21.0 I am not sure what you are asking. Which hardware ID has the network interface card? I have ran ipconfig /all and attached an image. Let me know what other information I can provide to you to help troubleshoot this problem. Thank

Post by eschwellinger on Codesys Network driver install for Codesys Control RTE x64 ^{CODESYS Forge talk (Post)}
Yes, either adding in the CODESYSContro_User.cfg because the driver will no longer appear in the list or type the name from the documentation in the configuration and when the gray check mark appears, the driver is also installed. It is just not selectable anymore.

Post by benemenn on Type mappings in Datasource ^{CODESYS Forge talk (Post)}
Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

Post by kevinm on Attaching Trace variable to Frame Configuration Variable ^{CODESYS Forge talk (Post)}
Is it possible to show a variable from a Frame Configuration in a Trace on that Visualization? I want to pass the FB for an AXIS_REF_ETC_SoE_Standard to the visualization and display live axis data in the visualization. However, I cannot find a way to use a Frame Configuration variable in the Trace Configuration dialog.

Post by snguyen on Atomic and Shared memory? ^{CODESYS Forge talk (Post)}
Hi, I've read that you can perform Atomic instructions like AtomicReadLInt on variables. However, I'd like to know if this uses stdatomic internally. My main question is : Is it possible to share atomic types in shared memory with CodeSys. If so, what types should they be declared as? If not, are the atomic functions lock-free or does it use a mutex?

the Answer is easy, you don't reapecting the codesys-behaviour and pre-request on a dll/so like you like to create. codesys won't load it about the fact that the dll isn't registered in codesys. check this page for more informations: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_extension_extension_sdk.html

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.

I am trying to create multiple branches in my project and I keep getting gaps in the ladder logic "wiring". I'm not sure if this is a graphical error or something else but every thing I've tried to do to correct it does not work. Has anyone else run into this or know how to correct it?

hi imdatatas, thanks for your suggestion! I added the process execution to be sure. In the meantime I reïnstall Windows but it dind't help directly. Finally I deleted CodeMeter Runtime Server after Codesys installation. Because this Service was not able to start. And it works (for now) :)!

How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

Post by timvh on IECStringUtils.FormatDateTime ^{CODESYS Forge talk (Post)}
There has been a fix in SP21. I tried it in this version with the option "Use unicodestring" enabled in the Visualization Manager and it worked if the variables used for the function are declared as WSTRING variables wsFormat : WSTRING := "%t[HH:mm:ss dd.MM.yyyy]"; wsTime : WSTRING; IECStringUtils.FormatDateTime(cbpResult := ADR(wsTime), uiResultCapacity := SIZEOF(wsTime), cbpFormat := ADR(wsFormat));
