Post by codesysdave on CoDeSys 3.5 SP20 "No Offline Help installed" ^{CODESYS Forge talk (Post)}
What does this message mean, in the Errors/Messages box? "[ERROR] MyProjectName: No Offline Help installed" In CDS23, I used to be able to select a system function with the mouse, and press F1. Help and description would popup. How do I get so-called On-line Help installed?

Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
Hi, Codesyscontrol 4.13.0.0 Raspberry Pi5 64bit with latest updates. Cant get working GPIO - no output and no input. SPI/I2C not tested. GPIOs B+/Pi2, Input/Output is set in the parameters, assigned variables int the Mapping. Absolutely no reaction. Do I need to configure anything else to make it work? Thanks!

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Post by janber on REFERENCE TO in an array ^{CODESYS Forge talk (Post)}
Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Post by phoward131 on Alarm Table Filtering ^{CODESYS Forge talk (Post)}
I actually just found the solution maybe. If anyone else is running into this, go to your Project Settings > Visualization > Advanced (check 'Visible' to see advanced settings) > UNCHECK 'Activate property handling in all element properties.' I am not sure what else unchecking this might affect but it seems to allow the alarm table to be filtered as expected.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Sorry, wrong expression. You have a 64bit system, so do I. You can also use the 64bit runtime, but most bib and commands are 32bit and are not properly supported. I had read somewhere that there are problems with I2C. That's why I recommend switching to PI_SL and using the correct gpio.

I am running CODESYS V3.5 SP19 Patch 2 (64-bit) I have buttons that are supposed to be either red or green depending on status. When I am logged out the colors look right. When I am logged in and running the colors are completely different and I can't understand why.

Post by winki on Not Possible to connect using control SL ^{CODESYS Forge talk (Post)}
Hello, I used to connect into my gateway using control SL tool 4.13, (it was called Update Linux.) I formated my computer, so today I install the new version of codesys and all package. Now I am not able to connect to my PLC using control SL. It says, check the status. Normally it used to worked perfectly before that.

Post by timvh on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
A Task is a standard IEC 61131-3 object, so logically that you can export the VISU_TASK. A visualization is no standard IEC 61131-3 object, so not compatible with other IEC tools. Just use the standard export / import functionality. These files are not IEC compatible and can only be used in CODESYS. But these do support visu objects.

Hello, I'm running the lastest version of Codesys 3.5 SP20 Patch 5, with the lastest version of Chrome. And I still get this "Webvisu not supported due to missing browser feature HTML5-Canvas" fallback with a quite simple webvisu containing some buttons, images, textboxed and a grid. What can I do? is that a configuration to change? Thanks!

Testing Codesys CNC. SMC Interpolator Throws me an error if my code surpass approximately 32000 lines of code. (SMC_CNC_INTERNAL_ERROR) What is the max lines of code SMC Interpoltor can handle ? I've been thinking breaking the code up into smaller sections, but that gives me a lot problems later if i want to use "Blocksearch" etc. I need to run approximately 2000000 lines of code.

It seems that the hmi sl license only works with windows. If i'm happy using web visu, rather than target visu, is possible to use remote opc-ua remote alarms without the hmi sl? Maybe it can be included in a different license that works on Linux? thanks

Hi, which CODESYS Version are you using exactly? Either update to 3.5.21.x if you are on 3.5.20.x if not - add a more secure pw. Seems that on adding the login credentials it is mandatory in 4.16.0.0 -to have complianct to password policy seems a bug that the message not occure.

Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.
