Post by thedertom on Help with DynamicTextGetTextW ^{CODESYS Forge talk (Post)}
Hi I try to get korean texts out of a textlist. For that I want to use DynamicTextGetTextW, but I am a little confused how it is supposed to work. The function returns POINTER TO STRING, but how do I get WSTRING? I succesfully used DynamicTextGetText with classical Strings. Thanks in advance!

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 rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Hi all, I’m new to codesys and working on some project. Codesy 3.5 V20 patch 3 Every time I try to use refactor codesys hang and not respond. I was trying to use repair function in installer but this is not helping at all. Wonder if anyone experience this behaviour?

@TimvH, Thank you, i think this way i can seperate the complete string to characters. Next part of the topic is converting the characters to an ASCII code. Is there an standerd function in Codesys for this? I alredy searched a few hours for it on the internet. no succes.

Post by willbechel on Errors about PLC configuration in CoDeSYs software ^{CODESYS Forge talk (Post)}
I saved it as the same project but in a different location. I opened this "new project". I clicked on the "Direct Login from Automation Builder" button. It automatically directed me to CODESYS, where I was able to create the "Create Boot Project" but first I also clicked login again but inside CODESYS keeping the automation builder login online. Additional Information: The "Create Boot Project" function in CODESYS is used to create a project that will automatically start when the controller is booted up. To create a boot project, you must first create a new project in CODESYS. Once you have created a new project, you can then use the "Create Boot Project" function to create a boot application. The "Create Boot Project" function will create a new application that is based on the current project. The new application will be saved in the same location as the current project. You can then download the new application to the controller.

Post by otbeka on CmpCrypto CryptoGenerateHash Not Outputting ^{CODESYS Forge talk (Post)}
Hi, I have been trying to use CryptoGenerateHash from the CmpCrypto Implementation library. My code is taken almost directly from the CryptoDemo.project example provided on Codesys Forge, yet the CryptoGenerateHash function does not write to the address listed in pHash. RTS_IEC_RESULT is OK, but I am getting nothing out of the function. No errors either, all my libraries are up to date. Any help would be appreicated!

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge talk (Post)}
With that I could make an array of varying size, but would still have to define the array type in the function's declaration VAR_IN_OUT stArray: array [*..*] of <pre-defined data type> END_VAR I wanted a function that could take an array of any type (e.g., a structured VAR) as an input. That way I could call it in multiple POUs to handle different arrays structures.

Post by dasch on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
This is a known bug in e!Cockpit. See Release notes of V 1.11: 1 e!Cockpit Release Version 1.11 (2022-07) ATTENTION: If a library that uses asynchronous tasks (e.g. WagoAppConfigTool, WagoAppCloud or function modules such as Dali-Master) is dragged into the project, the simulation cannot be started. It is already sufficient to add the library to the project (an FB does not even have to be instantiated). I guess you are using one of these libraries/modules in your project. We e.G. often use PWM modules, these are also affected.

Post by ofey on Symbol configuration / GVL ^{CODESYS Forge talk (Post)}
Hi! I have som variables that I communicate to a Modbus Master. These variables are declared in a "Global Variable List" where I have assigned them memory addresses. To organize this mapping I want to make a MODBUS list where I show all the variable names together with the memory address. Is there an easy way to export this list from CODESYS? Either through script or some export function maybe?

Hey, Sorry this isn't super helpful, but i had this problem once and was able to resolve it. I can't recall how I solved it and whether it was a problem with my codesys installation or the project itself. If it is the codesys installation, make sure all your required libraries and plugins are installed and available. compare with a colleagues installation if possible. I vaguely recall saving a copy of my project and deleting things one by one until the error went away...

Post by nathant on Some visualization objects disappear when user is logged in? ^{CODESYS Forge talk (Post)}
I am deploying a webvisu on Codesys 3.5 SP 19.2 with legacy user management. I noticed that when a user logs in, some text and a rectangle I have (for aesthetics) both disappear. I made sure that none of the objects in question are linked to a state variable. Anyone know the cause/solution to this? Nothing crucial to the machine's function is lost, but it is a little annoying.

Examples for the use of all function blocks from the Visu Utils would generally be very helpful!

Post by wiresplus on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
Hello, I need to take an INT input, and convert it to a WORD value. VAR DRV2Speed : WORD; //IO card takes a WORD where 16000 = full 10V output (equivalent to 50Hz) PumpFillSpeed : INT; //Users enter a value between 0 and 50 END_VAR IF <conditions> THEN DRV2Speed :=INT_TO_WORD((PumpFillSpeed/50)*16000); END_IF </conditions> According to me this should work - but it stays at 0, no matter what. What am I doing wrong?

Post by ojz0r on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
That calculation will not work the way you expect it to. If PumpFillSpeed is limitied to 0-50 then the only whole number would be 50/50 = 1 everything else is 0.0-0.9999... and since you are using word and integer only 50 would work since there is no representation for mantissa in integer values. Declare a temporary real variable and do the calculation and then do a REAL_TO_WORD in the DRV2Speed assignment.

Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

It is being worked on by many companies and its even-driven function blocks seem like a natural evolution of the object oriented industrial programming I have seen Gary Pratt (author of the Book of CODESYS and much more) so expertly implement and explain. I would expect CODESYS to have this front and center on their sights and, if they do not, I would be very interested in learning why.

I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej
