Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Post by stuartjr on Webvisu IE Page Scroll Bars ^{CODESYS Forge talk (Post)}
Is it possible to get scroll bars to show when displaying a web visualization in V2.3? I've got some big pages that I can scroll around when using the in-built visualization but when they are displayed in IE i can't seem to scroll around. All I can do it drag the window bigger onto my other display to get access to the extra area. I've also tried zooming the page out in IE but this doesn't seem to work at all.

Post by schnepper on Error building Extension SDK Linux code ^{CODESYS Forge talk (Post)}
I'm installed the CODESYS Control for Linux SL package and am trying to use the Extension API to call a simple C function. When I get to the step to run "make all" on the Linux machine, I get the error: build interface header: out/CmpFirstTestItf.h from CmpFirstTestItf.m4 ERROR: This functionname does not contain _cext (this is mandatory, see help for details): DEF_API(void',CDECL',external_struct__fb_init',(external_struct_fb_init_struct *p)',1,0x1F77E075,0x00000001) Why does "Generate Runtime System Files" create a function that does not have cext in the name? What am I missing?

Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

there is a new problem with latest bootloader version. The problem seems to be: Version from2024-04-20 does not work-> 2024-01-15 version works the workaround is a rollback to January version: cp /lib/firmware/raspberrypi/bootloader-2712/stable/pieeprom-2024-01-15.bin ./pieeprom.bin rpi-eeprom-config pieeprom.bin > bootconf.txt rpi-eeprom-config --out pieeprom-new.bin --config bootconf.txt pieeprom.bin sudo rpi-eeprom-update -d -f ./pieeprom-new.bin sudo reboot

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
It turns out that you can build JSON structures without ever calling the JSONBuilder function block directly. Instead, create a pointer to JSON.JSONData and invoke the necessary methods on its dereference. The parent object has a parent index of -1 (and an index of 0). EVERY other item (including keys, values, empty arrays and sub-objects) created by the setX methods needs the index to increase by 1. Then use the JSONByteArrayWriter FB to generate your JSON string

Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

I am rather new to Codesys and I'm trying to figure out how to get the status of an alarm. This to interlock the start of a device until the alarm has been acknowledged... I am not sure if IAlarm.GetState (METH) can be used for this purpose. If yes then could someone please briefly explain how to use this? https://content.helpme-codesys.com/en/libs/AlarmManager/4.1.0.0/Interfaces/pou-IAlarm/GetState.html Thx & grtz, Kris

I found out what I was doing wrong. I was entering the wrong IP in the gateway. I found that I have to enter the RPi's IP in the gateway field from this post https://forge.codesys.com/forge/talk/Runtime/thread/01703ca970/#d9f6 But I do not understand why it has to be the RPi's IP. Could anyone help me in clarifying this?

Post by trusty-squire on How to adapt Codesys Control SL to custom board ^{CODESYS Forge talk (Post)}
For general usage, these links might help you out. If you are looking at using I2C interfaces, examples from the Raspberry Pi will probably be useful, even if your board isn't a Raspberry Pi. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_rts_serial_com.html https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_raspberry.html If you're developing your own drivers, I can't help you there, although the link you provided will help. If you drill in deeper, the I2C page for example shows function block and method usage, etc. Good luck!

Post by vincentger on using ADS1115 ^{CODESYS Forge talk (Post)}
Any reason the ADS1115 wouldnt work with SP20.1 and Runtime 10.0.0.0 on the Raspberry Pi . Using Bullseye or Buster i run into the same issue: Libary and integration works in general as described above BUT i am seeing "bleeding" between the analog inputs . Specifically consecutive ones: So sometimes the raw from AI1 shows on AI2, AI2 on AI3, .. AI4 on AI1. Even with filtering i cant smoothen that out properly and i feel like something is wrong. Almost like the bus is stumbling over itself, or the request from Codesys to the device.

Post by warrumungi on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
Hi Thanks, Manuel, for providing this solution and insight. I too had exactly the same problem as you did. While I did implement a custom filter, I'd also like to point out what jinlee mentioned above...I see no reference to VU.PublicVariables.Clients.Current anywhere?? In my case I only needed to show a dialog on a "master" client, not all the clients, so I filtered by IP address to do this.

Post by faceplant on CmpDynamicText unresolved references ^{CODESYS Forge talk (Post)}
Hello! I am new to codesys so I am sorry if this is not the right place to ask this question. I am using codesys V3.5 SP20 Patch 1 + (64-bit) and a Groov EPIC PLC (GRV-EPIC-PR2). I am trying to build and deploy my application to the PLC, but when I log in I get 6 errors (codesys_error.png). It seems that the errors have to do with the CmpDynamicText system library which I have as version 3.5.20.0. I have tried to add CmpDynamicText to the ComponentManager section in the PLC's CODESYSControl.cfg file as described in this forum post and still hit the same error. I noticed that the library is grayed out in the library manager, which I think might be the issue. However I don't remember if it was grayed out before I encountered this issue. Please let me know if I can provide anymore info. Thank you!!!

Post by arnaud on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
Hi there! I'm using eCockpit WAGO software to develop HMI's for multiple projects. As I recently starting this, my knowledge on the software is somewhat limited (so maybe my question is a simple one). For most of my projects I can simulate the application and start it to test the code and HMI. However for two projects, I can initiate the "simulation activation" but I cannot start it. Nothing happens when I press start and the visualization shows "The online visualization is waiting for connection. please start the application". - I don't see any errors in the messages - Initially the project are made by a colleague, which moved on. I guess I'm forgetting something, like missing a setting. I appreciate any help I can get. If you need more information to help me out, let me know. Thanks!

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

Post by macros8 on Alarm Management - latched variable represented as Text list ^{CODESYS Forge talk (Post)}
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

Post by mark on IO link on IFM AL133x only single digital input on a channel ^{CODESYS Forge talk (Post)}
I have a problem with the CODESYS IO-Link SL software. When I insert a IO link master AL1332 and plug a discrete digital input to a channel it reads only 1 of the 2 available inputs on that channel. Is there anyone who sorted out if the second input is also usable? When we configure the module without the CODESYS IO-Link SL software then the second input on the channel can be used. At the moment we use some channels on a module as IO-link port, and some as discrete IO. It would be very nice if we can use both inputs on a channel with the use of CODESYS IO-Link SL.

Post by andrax on Save Recipe on Paspberry ^{CODESYS Forge talk (Post)}
Unfortunately not. The folder does not work. There are neither error messages nor any other indication that this may be due to missing rights. I have searched the entire forum and also tested the Codesys example. The simple recipe management generally does not work! The Raspi crashes with the extended recipe management from the example. I have now found another sample that works. https://forge.codesys.com/forge/talk/Engineering/thread/61c6a04b79/ Many thanks to mcodem. After some trial and error I have found out: xcreate must be called at least once at runtime. After that xload_write and xread_save work All other functions do not work. It is also possible to save to the /home/Documents folder. So it is not due to the rights. It would be nice if Codesys would check where the problem really lies.

"Hello, I'm Cedric Lee, a PLC engineer based in Korea. I'm reaching out about an ongoing issue with the connection when attempting to control Beckhoff modules using Raspberry Pi with CODESYS for the first time. I use CODESYS to target the Raspberry Pi's IP, install version 4.10.0.0 of the CODESYS Runtime Package, and upon pressing Start in the Runtime, the target connects to the Raspberry Pi. However, within about a minute, an error window appears, stating 'no connection to the device. please rescan your network,' leading to the disconnection of the target. This cycle repeats. I've attached some pictures for your reference. I'm using CODESYS Development System V3, Raspberry Pi 4 Model B (installed as 64-bit), and Beckhoff EK1100 modules. If anyone has a solution to this issue, please help. Your assistance is greatly appreciated."

Hi ryusoup, looking for the same functionality. I tried to use your code but couldn't figure out all the details. to enable Listener should it be called once or cyclically? the listener should be called with the intance of FB which you described? should it be this instance to be called cyclically too? I tried to make it simpler, just force the uiYear/uiMonth etc. but couldn't make it work. Could you please share some details how the whole struckture looks like? Would be great if you share an example UPD: found the issue. Your code works. Thanks for the posts

I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something?
