paulpotat posted a comment on discussion Runtime 🇬🇧
Update : The solution I mentionned in a previous post does not always work. Some Raspberry Pi CM4 still won't create the license container. I will open a support ticket.
-
Because we bought several raspberry pi licenses that can only be activated with a raspberry pi runtime.

Hello eschwellinger, Thanks for your answer, with this I was finally able to make it work by doing the following : install CODESYS Control for Linux ARM SL v4.13.0 uninstall CODESYS Control for Linux ARM SL v4.13.0 and make sure to select "yes" when prompted to uninstall WIBU CodeMeter Lite Runtime (v8.10.6230.501) re-install "CODESYS Control for Raspberry Pi SL" v4.13.0 It looks like the issue was probably related to the CodeMeter Runtime ? Best regards
-
Do someone have any information on this topic ? We tried several different CM4 boards without success, and we cannot install the licenses we bought anymore... Isn't CodeSys supposed to support CM4 Raspberry pi ?
-
Hello, I have a problem when opening the license manager for my raspberry pi (CM4 model) with runtime 4.13.0.0. I select "Device" --> "Soft Container" and click on my device in the scan window but I get this error message : Licensing info not available. There is no dongle attached to this device. I can't install licenses anymore, and I don't understand why is CodeSys looking for a dongle when I specified I wanted to use a Soft Container. Can somebody help me please ? Best regards
-
Hello again, After looking into it, I noticed that the release note of "CODESYS Control for Raspberry PI 4.13.0.0" mentions a bug fix titled "Support Compute module 4". Is it possible to have more details about this fix from the CodeSys team please ? Because I have several CM4 boards with the same hardware revision / OS but some of them works with the 4.10 runtime and others only works with the 4.13 runtime...
-
It looks like it works with 4.13.0.0 indeed. However when installing the runtime, it's not possible to select the multicore option (see attachment). But once the 4.13.0.0 runtime is installed, the logs seems to indicate that the runtime is running in multicore mode. Looking at "htop" output, it seems like it actually is running on multiple CPU. This is very misleading, is it normal or is this a bug ? Thank you for your answer @eschwellinger, BR

Hello, I was wondering if there is a way in codesys to exclude the traces from the search when using the "ctrl+F" window ? That would be nice to improve the search functionnality when looking for a specific variable. Sometimes when I iterate through all occurences with the "find next" button, it opens the trace configuration window. I would expect to be able to close it and go to the next occurence with the "find next" button, but after closing the trace configuration window the search says it has...

I still have the same problem with Codesys 3.5 SP18. Initially, my project is ~5 Mo. I work on it for like 3-4 days and it goes up to ~10Mo. If I make an export of the project and import it in a new empty project, it goes back to approximately 5 Mo. Why is it doing this ?
-
Thanks for your reply ! I'm not sure I understand exactly what you mean, what would "myArray" be in that case ? Also with what value is "x" supposed to be initialized with ?

Hello, Is there a way to iterate over enum members in CodeSys ? For example, if I have the following enumeration definition : TYPE E_REQUEST_TYPE : ( A := 0, B := 1, B := 2, D := 3, X := 42, Y := 85 )BYTE := NONE; END_TYPE Is it possible to iterate over each enum member in a for loop for example ?
-
Hello, I want to know how many connections I can add to a profinet device in CodeSys. So far, it looks like I can only add 64 variables to a Profinet device in CodeSys. I can't find this value in the documentation for the CodeSys Profinet Device. However it says in the documentation for the CodeSys Profinet Controller that the maximal number of connections is 64 by default but can go up to 1024. How can I increase the number of connection of a Profinet Device ?

Sadly, I did not :( I was able to get the type of the node (I could know that a node was a "Bus controller" for example), but not much more...

Hello, I have a problem with the CAA File library : every file created using the Open FB is read-only for everyone but the root user.

Hello, I'm trying to setup a data logging mechanism to capture some bugs. What i want to do : - Save a variable value in a buffer periodically - If a certain event occur, save the entire buffer in a csv file I'm trying to use the Datalog Manager module to do this, but I'm not sure how to configure it. It looks like I can only configure the module to save the csv file periodically : Can I do this using this module ? Or do I have to do it by hand ?
-
I would create a type like this : TYPE LREAL_WORD : UNION value : LREAL; // Needs 8 Bytes in memory regs : ARRAY [0..3] OF WORD; END_UNION END_TYPE Then in your program you can declare your variables like this : my_var : LREAL_WORD; reg_1 : WORD; reg_2 : WORD; reg_3 : WORD; reg_4 : WORD; // ... // Maybe you'll have to change the order here... my_var.regs[0] := reg_1; my_var.regs[1] := reg_2; my_var.regs[2] := reg_3; my_var.regs[3] := reg_4; Then it will automatically update my_var.value to the corresponding...

Hello, You can check the export.py file of this github repo, it generates text files for every POU in a project (and more). To do so, it iterates over every object in a project recursively, starting with the tree returned by projects.primary.get_children(). I hope this can help you, BR
-
Easiest way to do this is to create a type like this : TYPE uWordBytes : UNION rValue : WORD; // Needs 2 Bytes in memory abValue: ARRAY [0..1] OF BYTE; END_UNION END_TYPE Then in your program you can declare your variables like this : my_var : uWordBytes; my_var_as_word : WORD; // ... my_var.rValue := my_var_as_word; Then it will automatically fill the array my_var.abValue with the corresponding bytes ! You can access those bytes the same way : x[0] := my_var.abValue[0]; // First byte x[1] := my_var.abValue[1];...

Okay I finally understood this ! The 9th byte is the last part of my IP address : for example if my ip is 192.168.1.42 then the 9th byte has to be equal to 42 (0x2A). So in case anybody needs this one day (who knows), to perform the same type of network scan CodeSys uses you have to send a UDP broadcast frame containing the following data : # WIFI c5 74 40 03 00 20 00 00 03 xx 83 01 02 c2 00 04 00 00 00 00 # ETH c5 74 40 03 00 10 00 00 03 xx 00 00 02 c2 00 04 00 00 00 00 Where "xx" is the last byte...

Hello, I was wondering if it was possible to create a custom CLI for CodeSys applications ? For example I would have an application "my_app" running on a PLC, and if I connect to this PLC I could run commands in the terminal like this : my_app [Options] Do someone know if it's possible ? BR
-
After some investigation, it looks like the 9th byte changes depending on the network IP. For example on the same WiFI network : - if network ip is 192.168.100.xxx then byte 9 is "05" - if network ip is 192.168.99.xxx then byte 9 is "03" - if network ip is 192.168.43.xxx then byte 9 is "8A" - if network ip is 192.168.1.xxx then byte 9 is "34" I tried some math operations on the ip to get those values as results but I can't figure out how it's calculated...
-
Ok so far I understood this : - Byte[0:4] = Some sort of header (it never changes) - Byte 5 = Change depending on the interface type (10 for ethernet and 20 for WiFi) - Byte[6:7] = ? (can be set to 0 without issues) - Byte 8 = Always equals to 03 - Byte 9 = ??? (can't be set to 0 otherwise devices won't answer the broadcast message) - Byte[10:11] = Changes depending on the interface type (0000 for ethernet and 8301 for WiFi) - Byte[12:15] = Always equals to 02c20004 - Byte[16:19] = Count of UDP broadcast...

Hello, I'm trying to understand how the "Scan Network" function of CodeSys operates.

Hello, I've been trying to disable user management without success. It says in the documentation that you just need to perform a reset origin on the device. When I do that user management seems to be disabled at first, but after a few reboot / flashs the credentials popup comes back. How can I really disable it ?
-
Well if you want something similar, you can create a union type like so : TYPE DWORD_BYTES : UNION value : DWORD; bytes : ARRAY[0..3] OF BYTE; END_UNION END_TYPE Then in your program you define varD as a DWORD_BYTES object and you can access its bytes like this : varD.bytes[byte_position] := varB; Where byte_position can be 0, 1, 2 or 3. And if you need to change varD value you can do this for example : varD.value := 16#FFFFFFFF;
-
Hello, I would do this : varD := (varD AND 16#00FFFFFF) + SHL(TO_DWORD(varB), 3*8); However there might be better ways to do this, I'm not sure...

I just found how to do it and it's actually very simple to do. You just right click on any .project file and choose Open With > Choose Another App then you have to check the box titled Always use this app to open .project files. and select the other CodeSys. Sorry for the dumb question, BR

Hello, Thank you very much for your answer ! We ended-up re-installing the OS on the PLC that was bugged and it worked but your solution is way better (and faster) ! I'll try it if we stumble upon this bug again :) Thanks again for such a detailed answer, have a good day ! BR
-
Could'nt you just change this line : iState:= 6; To : iState:= 0; So your state machine goes back to state 0 and it loops infinitely ? If you want to time it you can just add a wait state with a timer.
-
Try to run the following command in a terminal : htop Then you can monitor CPU usage and identify which process is eating all the CPU.
-
Hi, You should check for an infinite / very long loop in your code that could be blocking the execution. What kind of PLC are you using ?
-
Hello, One solution to make CodeSys and Python to exchange data could be to use a Shared Memory (see this example). This allows you to dedicate a space in the memory where both Codesys and Python are able to read/write. You can also use the OPCUA functionnality of CodeSys to Exchange data if you want, but I have not tried it yet. However if you just use CodeSys for building the interface I think it would be easier to go full python. Hope this helps, BR

Hello, Were you able to fix this issue ? We are having the same kind of problem using CodeSys 3.5.18...

Hello, I think it would be easier for you to use the CAAFile library instead of Sysfile. The File.Open FB of the CAA_File library will directly return a string with the content of your file. You can find examples here.

Hello everyone, In the documentation for the Persistent Manager module, it says that "the writing of a big amount of persistent variables may take a lot of time and can block the respective task very long". How much is "a big amount" ? For example if it's running on a raspberry Pi 3 with 1GB of RAM and a writing speed of around 15 MB/s ? Also there is an indication of a size limitation in the documentation, but what is the limitation on the updating speed ? For example if I want to store one REAL...

Hello, I had problems with that too, what you can do is use the AppRestoreRetainsFromFile and AppStoreRetainsInFile functions from the CmpApp library. Basically, you can use them like so : application_ptr : POINTER TO CmpApp.APPLICATION; res : DINT; // Get application pointer application_ptr := CmpApp.AppFindApplicationByName('Application', ADR(res)); IF application_ptr <> 0 THEN // Restore the variables CmpApp.AppRestoreRetainsFromFile(application_ptr, '/home/pi/retains.ret'); // ... // Store the...

Hello, I have a question about how CodeSys deals with out of bound accesses. For example if I define an array like so : test_array : ARRAY[0..9] OF BYTE; And in my code if I do : i := 10; test_array[i] := 12; Surprisingly, no exception is raised and the value is written in the memory at the corresponding address. I can even modifiy the values of other variables in the programm by doing that. So my question is : is there a way to detect an out of bound exception ?
