Post by jacobwago on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello, I have experienced the same issue as described above but for the Modbus Serial configurator. Looking for a solution. In v3.5 SP19 Patch 7 the Modbus Serial Master Slave configurator has a "virtual" limit of 10 channels. In v3.5 SP18 Patch 5 this virtual limit does not exist. I can successfully copy back and forth from 18 to 19 with out any build error. However, this is not a good solution for our customers. What is even more confusing is that the IoDrvModbus library is the same version (4.3.0.0) for both SP18 and SP19. Please help in providing a fix to the virtual channel limit of 10 in SP19. Thanks,

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Post by taqamert on CANopen PDO Issue with Pressure Sensor in Codesys ^{CODESYS Forge talk (Post)}
Hello everyone, I am using an IFM CR0303 model PLC, which has a tilt sensor and a pressure sensor connected via CANopen. Both sensors are from the same brand (ATEK). I can read data from the tilt sensor without any issues, but I am unable to read data from the pressure sensor. I have added the EDS file in the PLC configuration and adjusted the node-ID settings. When I check with the PCAN-View application, I can see that the selected PDOs are coming through, but the data is not reaching the Codesys side. What could be the issue, and what can I try to resolve it? Can anyone help me?

Post by timvh on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
It seems you have 2 network interfaces. Did you try eth1? Did you already configure the IP address for this interface in Linux? If yes, then maybe undo this. - or only set eth0 in the Nic configuration without anything else (so no IP address, because this is already set in Linux). For more information about the Nic settings, see (probably already read it?): https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_obj_deploy_control_sl_configuration.html PS, if you only want to run CODESYS Control SL, you don't necessarily need the Virtual PLC variant. You could also install and run the CODESYS Control SL Runtime in the Host operating system. This way you should also be able to access the serial port and directly access all ethernet ports. Maybe this is easier?

Post by shafiq-dsc on Beckhoff EK series cannot detect but BK1120 detect ^{CODESYS Forge talk (Post)}
Dear Support, I have i950 wants to connect with Beckhoff EtherCAT coupler BK1120. There are 2 GSD files for BK1120. 1. BK1120 without MDP.(EtherCAT ESI Device Description (XML)) 2. BK1120 with MDP. (EtherCAT BKxxx (MDP) configuration files) When connecting the BK1120 with i950, scanned devices detects BK1120 without MDP from ESI No1 above. But the KL1408 & KL2408 not detect because they have ELxxxx IO type. When manually insert BK1120 with MDP, the KL1xx8 is able to add manually also but the error shows and Install Missing Descriptions appears. The questions; 1. Why the error occurs? 2. Can the i950 connect with KLxxxx IO type or not? Regards, Shafiq

@Strucc.c: thanks very mutch. Yes, I think that was the problem. I tried yesterday a similar function, i have found: IEEE32 in REAL FUNCTION IEEE32_TO_REAL : REAL VAR_INPUT IN:DWORD; END_VAR VAR PTREAL:POINTER TO REAL; END_VAR PTREAL:=ADR(IN); IEEE32_TO_REAL:=PTREAL^; END_FUNCTION REAL in IEEE32 FUNCTION REAL_TO_IEEE32 : DWORD VAR_INPUT IN:REAL; END_VAR VAR PTDWORD:POINTER TO DWORD; END_VAR PTDWORD:=ADR(IN); REAL_TO_IEEE32:=PTDWORD^; END_FUNCTION http://www.oscat.de/community/index.php/topic,357.0.html And this works perfect. Now, the only thing that isn't clear is the libary "FloatingPointUtils, 3.5.17.0 (System)"... For me, the libary doesn't work. But the problem is now solved. Thanks a lot.

Hi, When trying to activate a control Basic L license on a Wago PFC200 750-8203 the error The selected container ... does not fit your ticket comes up and won't allow licensing. I have deleted the /var/opt/codesys/cmact_license/ content 3 times and the container number changed each time after a reboot, but the problem persists. Not a happy first time experience with those weird application based licenses. IDE is 19.20. This was a e!Cockpit FW22 PLC and I used Deploy Control SL to make the green web interface red. WBM shows Codesys 2 and e!Runtime active which is a bit weird. What do I do now? Regards Heinz

Post by askic on Name Validation of Visualization objects ^{CODESYS Forge talk (Post)}
Hello, In my projects, I'm following this recommendation about the rule names in Codesys https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html, so I always use backtick identifiers, not only for variables, but also for the object names. However, I have noticed that in the current version of Codesys, when adding Visu object, it is not allowed to used these identifiers in the name. This is very different from all other objects like, folder names, POU names, Variable list names etc. I wonder if there is some hidden settings I can use to enable backtick identifiers in the Visu object names? Attached is a screenshot with the details. Thank you!

Post by askic on Library Documentation Export Error ^{CODESYS Forge talk (Post)}
Hello, I have encountered a very strange and non descriptive error when creating libraries. Basically, when user just create a new CODESYS library, and then just add Text List, save build with no errors and then try to save as compiled library, the following error would be generated: "The library documentation export error" and nothing more, just like shown in the attachment. Of course I have installed package CODESYS Library Documentation Support v 4.6.0.0 I'm Using Codesys 3.5.20 Patch 2 Does anybody have any suggestion about the cause of this error or any advice on how to troubleshoot further?

Post by janber0206 on Adding PLC to the List view resolves in Unknown Error ^{CODESYS Forge talk (Post)}
Problem Solved The Problem was within the Usermanagment. There should be 6 files for the Usermanagment in /var/opt/codesys/ .UserMgmtDB.csv .UserMgmRightstDB.csv .GroupDatabase.csv .UserDatabase.csv_ .GroupDatabase.csv_ .UserDatabase.csv The file .UserMgmtDB.csv was missing. I moved the other files in a savefolder. Full Step by step instructions stop the runtime with sudo /etc/init.d/codesyscontrol stop rename the following files on the PI: (or save them and then delete them) in this directory: /var/opt/codesys/ .UserMgmtDB.csv .UserMgmRightstDB.csv .GroupDatabase.csv .UserDatabase.csv_ .GroupDatabase.csv_ .UserDatabase.csv then restart the Runtime: sudo /etc/init.d/codesyscontrol start now reconnect the PLC via the Automation Server - here you will be asked to create a new CODESYS user password, The user management files deleted above are then created again (in /var/opt/codesys/ on the PI).

Post by tyleretn on Codesys 3.5 SP18 P4 Freezing on Library Update ^{CODESYS Forge talk (Post)}
I have created a library with both code and visualizations to be used in multiple other projects. After I update the library version into the library repository, I have much difficulty updating the version into the main project. I can always update the library version in the Library Manager just fine. My issue, is sometimes Codesys will freeze when opening the visualization that uses the library visualizations. Sometimes it opens, but freezes when I try to access the library visualizations from the Visualization Toolbox. I try letting Codesys run for upwards of 4+ hours and it is stuck in this state. On very rare cases I have no issues and can continue with my work. I haven't found a consistent reason or work around. Has anyone else had this happen?

Post by rockallsue on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Some developers export ST code manually and edit it in VSCode, then copy it back. However, a more practical approach might be using automation scripts (PowerShell, Python) to extract and inject code into the CODESYS project. You could also check if CODESYS Automation Server or CODESYS API allows better ST access for external tools. https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html Network drive issues are particularly painful. As a mitigation, you could try using local project storage with periodic cloud sync instead of directly saving to a network drive. Using Rsync or Syncthing for automatic but safe synchronization might reduce risks of file corruption.

Hi, How can i display targetvisualization in full screen on the target device? I installed Targetvisu For Linux SL 4.16.0.0 on target device which contains Raspberry PI 64bit PIXEL desktop. When i connect my PLC program to the remote targetvisu, the targetvisu displays for 60% horizontally. We contacted CODESYS and they said it is a bug. they had a workaround, and with the settings below added to the file /etc/codesysvisualization/CODESYSVisualizationTV.cfg, the targetvisualization display for 100%, but with the taskbar at the top. VisuClient.BestFit=1 ;VisuClient.ScaleTypeIsotropic=0 VisuClient.FillWholeBackground=1 [CmpTargetVisu] WindowPositionX=0 WindowPositionY=0 WindowSizeWidth=1280 WindowSizeHeight=800 WindowType=2 How can we let it display fullscreen without taskbar?

Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

I can connect with UaExpert but I cannot see my Application or browse my values. What is missing?
