Post by peterkcontrols on Codesys Network driver install for Codesys Control RTE x64 ^{CODESYS Forge talk (Post)}
Hello I am trying to download my project onto my Codesys Control RTE x64 soft PLC. and I have had an issue when downloading. [FATAL ERROR] Unresolved reference: 'SYSETHERNETADAPTEROPEN' [FATAL ERROR] Unresolved reference: 'SYSETHERNETADAPTERCLOSE' [FATAL ERROR] Unresolved reference: 'GETNUMBEROFADAPTERS' [FATAL ERROR] Unresolved reference: 'GETADAPTERINFO' [FATAL ERROR] Unresolved reference: 'SYSETHERNETIPFRAMERECEIVE' [FATAL ERROR] Unresolved reference: 'SYSETHERNETETHFRAMESEND' [FATAL ERROR] Unresolved reference: 'SYSETHERNETETHFRAMERECEIVE' [FATAL ERROR] Unresolved reference: 'SYSETHERNETIPFRAMESEND' [FATAL ERROR] Unresolved reference: 'SYSETHERNETFRAMERELEASE' Looking on the forum I have found other people had to install the network driver, which I have done following this youtube video by codesysGroup: https://youtu.be/10oj4wABaKc?si=664l83JXUGQSDlAe I have added the network driver, please see attached image. I have checked my BIOS to make sure my secure boot status is disabled, see attached image. when I go to component manager, the drop down menu doesnt have the new network adapter, see attached image. I have not yet purchased or installed any licenses is that what I am missing? What other reason is there that I can't download to the runtime. Thanks

Post by sbhaskarla on WebVisu File Transfer Error ^{CODESYS Forge talk (Post)}
I’m encountering an issue when downloading CSV files via the WebVisu button input config -> file-transfer option: • Custom directory: /plcdata/csv_logs/filename.csv o Error: Error 4 – Error during file transfer • Sandbox directory: /var/opt/codesys/PlcLogic/plcdata/csv_logs/filename.csv o Result: Download succeeds without error. Actions taken so far: 1. Added /plcdata/csv_logs to codesyscontrol.cfg (see attached). 2. Enabled file-transfer services in codesyscontrol_user.cfg (see attached). 3. Confirmed that the PLC writes CSV files correctly to /plcdata/csv_logs/. Despite these settings, WebVisu still returns Error when accessing the custom path 1. Using the placeholder file path '$$CSVLOGS$$/filename.csv' and it returns Error 6. 2. Using the literal path /plcdata/csv_logs/filename.csv and it returns Error 4 Could someone please help me determine what additional configuration or troubleshooting steps are required to serve files from /plcdata/csv_logs/? Please find screenshots attached for better understanding and I have also attached the config files

Post by jinlee on Symbol Configuration ^{CODESYS Forge talk (Post)}
Hi guys, I am working on an old project which using Codesys v2.3 talks to Beijer's screen TA150 (IX-Developer 2.20). Codesys v2.3 is different with 3.5 and Ecockpit. I know how to import the symbols from PLC to HMI for Codesys 3.5 and Ecockpit. However, I do not know how to do it on Codesys v2.3. I know that I can make excel sheet to import and export from the HMI and add whatever I want based on PLC. However, is there any quicker way of doing this? So that I can directly import the symbols (tags) from PLC (Codesys 2.3 to HMI).

Post by wistaro on How to use PLC_Open FBs with PROFINET servodrive (PROFIdrive layer) ^{CODESYS Forge talk (Post)}
Hello, I would like to know if there is a PROFIdrive layer in CODESYS. I am already familliar with Codesys's SoftMotion on CANOpen/EtherCAT (to control PLC Open FBs), and I need the same kind of stuff for PROFINET-IO devices; In my configuration, I have a CIFX board from Hischer to enable IRT, the SoftPLC "Codesys Control RTE V3 x64", and a servo-drive from INFRANOR that implements PROFINET / PROFIdrive (with IRT) protocol. This drive works well with the Object Technology of Tia Portal, but some customers use Codesys. Do you have an idea how to do that? Thanks in advance. Regards, William ROMIGUIERES INFRANOR France

Post by madskaizer on ModbusTCP Slave Device, maximum uiClientConnections? ^{CODESYS Forge talk (Post)}
I got a Wago PFC200V2, running Codesys 3.5.16.40, 100ms scan cycle, consumes about 20ms. It will randomly crash the runtime every 10 minutes to a few hours. We suspect an overloaded ModbusTCP Slave Device, as this is work done by a 3rd party contractor, but we can not find anything in the help files or documentation, that mentions a hard limit on maximum number of clients connections. This PLC currently has 44 client connections to the Slave Device and 29 slaves configured for its own Master Device. This topic metnions a hard limit of maximum 16 connections, but where is this written? https://forge.codesys.com/forge/talk/Engineering/thread/bd95b9d6d2/

Post by micik on Changed Device of Rapberry Pi to MC SL instead of standard SL and cannot connect anymore ^{CODESYS Forge talk (Post)}
I have a test application and use Codesys Control for Rasp Pi SL. I made a mistake and updated device from MSL to MC SL, and now if I try to go online with archived version of the project I gett error message that IDs are different between project device and target device. Of course, I can go online if I changed device in the project from SL to MC SL, but I'm not sure that is correct. So I have two questions: 1. What is the actual difference between MC SL device and standard SL device when it comes to raspberry pi 4? 2. What change I need to do on raspberry pi4 side to change device back from MC SL to SL? Thank you!

Post by rer-code on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue. If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input. Best regards

Post by blitz on Arcs intersection ^{CODESYS Forge talk (Post)}
Does anyone have an idea how to run such a spiral on CNC smoothly without stops? SMC_SmoothPath and SMC_RoundPath don’t help. In general according to the documentation they should work on arcs but in the example only straight lines are shown and I get the impression these functions only work for straight lines.

Guess you could just add two modbus slaves with the same ip, to enlarge the 10 channel limit.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi, Is there a process to restore Persistence Manager files? I have backups of persistence variables used in a machine that is currently operating and tuned and all set points adjusted. There are about 500 persistence variables, they are building another identical machine. I would like to use Persistence Manager files from the first machine in the second also. I have tried copying the files and replacing them on the new RPI but then the Persistence Manager gets errors and then they are all reset to 0 etc I have tried adjusting the times to match. Instead of replacing whole file, I tried just changing the contents inside the file, but still does not work. I may be missing something here, but surely there must be a way to load a backup. Thanks!
