Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

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 sigurdrb on Codesys and error messages, warnings exceptions etc. ^{CODESYS Forge talk (Post)}
Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

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).

Post by struccc on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hi, Might be a good idea first to try out the connection and the device with some handy software, like Modbus Poll. There you can see better, what's really going on... - Is it really connected? - What error code does it return? - Can it read from the register address? - Maybe try Input registers and Holding Registers - can make a difference - Sometimes register addresses are messed up: shifted +-1 (mixing of 2 standards) - Sometimes register addresses start with offset 30000, 40000 ... - Are you using the right protocol? - Is it RTU or TCP? Maybe ASCII? - Can even have a look at the data packets, etc... All this is easier to figure out first with some modbus utility... and then to set it up in CODESYS should not be an issue. P.

Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
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?

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge talk (Post)}
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

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!
