Post by ron-rp on Errors with VisuUserManagement library ^{CODESYS Forge talk (Post)}
Hi all, I've played a bit with the VisuUserManagement library, and some other security option in my project, and I started getting this error when logging in - see attached pic. something to do with a specific screen in the library - VUM_Login. Also, Codesys started to ask me to log in to the library when logging in, asking to log in as user of the groups Maintainer or Owner, which I dont know either users (attached pic). when I close the login screen and try to log in to the PLC again, everything works again until I close and open Codesys. I do use user and password to login to the PLC, and this login screen is fine I know the user and pass I setup. anyone know what did I do wrong here and how to fix it?

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge talk (Post)}
I let this project rest for a while and picked it up last week. I have been in contact with the support from beckhoff and got the information that the terminals were identical (communication wise). As the Log of the Axis (not the drive's log) shows the error when trying to write into the register 0x8012 and set the value for an encoder to a value that is the default - at least according to the manual - I was wondering if it is possible to "not write that value" to skip that part? Or am I misunderstanding the way the library communicates with the drive?

Post by cfam on Codesys Control for PLCnext SL, Bus not running ^{CODESYS Forge talk (Post)}
Good day I would appreciate it if you can give me some advice on how to fix my "Bus Not Running Error". I am Using Codesys 3.5 SP20 and Codesys Control PLCnext SL V4.12.0.0. Codesys control was installed on the device and I can log into it but it seems that it does not pick up the PLC or the IO attached (Please see attached Image). The Bus Cycle Task of the AXL F 2152 is set to Main Task and the "Always update Variable" is Enabled on each IO Module. My Main Task interval is set to 100ms and Priority is set to 0. I have tried other options and none seem to work. Your response to this issue will be highly appreciated.

Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by jari-koivuluoma on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
When I create a new textlist in Codesys 3.5 SP19 Patch 5, it wont appear in the dropdown menu at Rectangle element > Dynamic texts > Text list. If I just type the name of the textlist to the field (in quotes), I get an error saying that some file is missing. Any good ideas what to do and what is going on. I recently updated to that version and I only now noticed this when I needed to add a new textlist so Im quite screwed with this not being able to add text lists. While im typing this, I tried copying an existing list and modifying it and it seems to show. Any ideas?

Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

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 pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

Post by akfarslan on The application does not exist on "device" ^{CODESYS Forge talk (Post)}
Dear All, I am using CODESYS 3.5.19 SP4 with a PLC device. When I try to download my program to the device, I get the error: "The application 'Application' does not exist on the device". Additionally, after restarting the device, the program does not run automatically. When I connect to the device using WinSCP, I can see that the application.app file is uploaded to the root directory, but the device does not automatically start the application. I tried using the Create Boot Application option, but it does not resolve the issue. Is there another configuration step I am missing? How can I fix this problem? Thank you, Best regards,

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
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 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).

Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Is there a specific setting that needs to be enabled for this feature to work? If so, could you please let me know where to find it? I’ve already tried uninstalling and reinstalling CODESYS, but that didn’t resolve the issue. Also, i have a teammate who have exactly the same computer as me and he didnt encounter any issue. Thank you in advance for your help!

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, After some more tests, here is what I found out. It seems we have to increase the uiKeepAlive and tPingInterval parameters. If I increase the uiKeepAlive value to 60s and the tPingInterval to 30s, then if I disconnect the ethernet cable from Codesys and publish some messages to which Codesys subscribes to and then reconnect within 30s, I will get the messages. If I don't reconnect the cable within 30s (ping interval), the client goes in error with "ACKNOWLEDGE_TIMEOUT". When this happens, it will not automatically reconnect after reconnecting the cable. I have to disable and re-enable the client but I will not get the published messages. I need to do more tests because there are a lot of weird things happening when playing with the ping interval and the keep alive. It is not clear to me what does what. I even ended up not receiving messages anymore, even if I disabled and re-enabled the mqtt client. The client did not give any error. The only way I was able to get messages again was by modifying my client ID. After that, if I try to re-use one of the old client IDs, nothing works (publish, subscribe) and I get a TCP_INIT_ERROR and sometimes a TCP_READ_ERROR. I need more explanation/documentation about these weird behaviors. Maybe it is the way I use it, maybe it is related to the broker (I am using Mosquitto with default parameters). When using a Node-Red client, everything works perfectly. I am trying to achieve the same behavior with Codesys but it seems impossible so far.

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
CODESYS Control for PFC200 4.13.00 CODESYS IIoT Libraries SL 1.11.0.0 Application Based License: CODESYS Control Standard M I have (2) projects with similar code base and both using Wago PFC200. On the second project I am seeing 2 things that I have not been able to resolve: 1) Errors in the log under the Ethernet Item: IoDrvEthernet: [PCI\E1Q51CE62] Could not be found on target! Please check the Ethernet settings. 2) Exception for CPU Load. "Processorload watchdog: plcload=100, maxplcload=95" I have slowed down cyclic tasks on this project, even though on the first project there is actually more code - and it does not exhibit this behavior. In looking at the CPU loading via Linux 'TOP' command there appears to be 20% idle. So plenty of headroom (my opinion). In an effort to troubleshoot I have duplicated the target hardware on my bench. It ran overnight without a CPU load exception. On the test system, I have tried (3) version of the ethernet device. 3.5.16.0 3.5.17.0 and 4.2.0.0 Presently the log does not show the error, but status says the module reports an error. I really do not know if this issue is related to the CPU load exception. The issue does not appear to effect ethernet communications (ModbusTCP or SNMP or Webvisu or PuTTy into Linux Shell). On my test bench I have ModbusTCP slave simulators for all ModbusTCP slaves, but only (1) of the (5) SNMP devices present.
