Post by ofey on Symbol configuration / GVL ^{CODESYS Forge talk (Post)}
Hi! I have som variables that I communicate to a Modbus Master. These variables are declared in a "Global Variable List" where I have assigned them memory addresses. To organize this mapping I want to make a MODBUS list where I show all the variable names together with the memory address. Is there an easy way to export this list from CODESYS? Either through script or some export function maybe?

Post by eschwellinger on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
you need at them moment a download once (for the configuration files generated including addresses) then stop the plc - exchange the persistence file ( without the config file) This will be improved to 3.5.18.6 and 3.5.20.0. (possible then to generate offline bootproject including full persistenmanager files) - this is if you have not 100% the same bootapplication on the devices. In case you copy the whole Application (PLCLogic) directory it should work out of the box - but only with 100% same bootprojects as mentioned above. By the CODESYS Automation Server would help solve this too.

Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
SOLVED!!! In this imx8 max_cstate=1 in kernel boot parameters is not working! We found a workaround: #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <stdint.h> int main(void) { int fd; uint32_t value = 0; fd = open("/dev/cpu_dma_latency", O_WRONLY); if (fd < 0) { perror("Error opening /dev/cpu_dma_latency"); return 1; } if (write(fd, &value, sizeof(value)) != sizeof(value)) { perror("Error writing to /dev/cpu_dma_latency"); close(fd); return 1; } while (1) { pause(); } } This simple code launched before CODESYS do the same work! Now jitter is identical as measured by cyclictest!

Post by simotion on Online view : code is scanned ^{CODESYS Forge talk (Post)}
If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Post by davidbo on How to allow a user to handle certificates without access to sourcecode? ^{CODESYS Forge talk (Post)}
With CODESYS V3.5 it is possible for a user to do the following things among many others. 1) Handling certificates especially move a certificate to the trusted folder. 2) Change password and create new users for OPC UA access However it requires access to the whole projects and its source code. Something you might not want to hand over to an end user for a stand alone product. Is there a way out of this problem?

Hello? I have a problem with datasource... I am trying to connect to a OPCUA server. I create a datasource, but I can not login into it. I need to use login credentials to login... Everything works fine in UAExpert, but in codesys I cant seem to get in properly using the login credentials... I have tried to configure the datasource initializer but seem to keep failing... Do I need to call it somewhere ? Will the find endpoints work with this configured to store my password ? !

Post by mmoncada on Dinamically loading recipes ^{CODESYS Forge talk (Post)}
I'm having trouble with the initial loading of recipes. I can create them and load one or the other, but when the program restarts the recipes are not listed. I'm calling: RecipeManCommands.ReloadRecipes and then RecipeManCommands.GetRecipeCount which returns 0 recipes. None of the methods returns error and if i call them again after RecipeManCommands.CreateRecipe RecipeManCommands.ReadAndSaveRecipe getRecipeCount returns the number of recipes created. When i restart the system, once again they are not listed even though the recipe files are there. Any ideas? Martin Btw, Codesys 3.5 SP 16 Path 9

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Post by wehling-h on PI Input value ^{CODESYS Forge talk (Post)}
Hi geoweil, have you tried to save changed values to remanent area or using a VAR RETAIN? After restart you have to initialize Counter with last remanent value. Depending on changes per cycle and the possibilitiy of your control unit to write remanent storage. Otherwise you need a buffering system to ensure save backup of last PI_Counter value. May you could read this Thread to get further help: https://forge.codesys.com/forge/talk/Engineering/thread/31e1c8349e/#bf48

Post by timvh on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
It depends on your application which CPU speed and RAM size you need. If you think the Control Standard S license is sufficient then my guess is that your selected PC has no problem running your application. There are no more "hardware" based single licenses available anymore, only application based licenses. So this "Raspberry Pi" restriction for home automation is not applicable anymore. For more information see: https://store.codesys.com/en/howto_applicationbasedlicenses

Post by andrax on Stop Programm geladen Ausnahmefehler ^{CODESYS Forge talk (Post)}
Hallo, ich habe seid neustem ebenfalls dieses Problem auf den Raspberry. Codesys 3.5.18 Nach dem Download geht die SPS in STOP und es blinkt schwerer Ausnahmefehler. Der Fehler kommt sporadisch und ist nicht reproduzierbar. Es passiert beim kompletten Download, aber auch bei Änderungen. Wie kann ich den Fehler eingrenzen? Nachtrag: Wenn der Fehler kommt, ist die Runtime auf dem Raspberry nicht mehr ansprechbar. Der Raspberry selbst schon. Für einen neuen Download muss ich den Raspberry neu starten. Das selbe ist auch in der Programmierumgebung, die Software hängt sich auf.

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by thomas-moba on "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ^{CODESYS Forge talk (Post)}
Hello, I need to execute "sudo" commands via CoDeSys 3.5 SP 19 P5 using the "SysProcessExecuteCommand2" function. Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

Post by thomas-moba on "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ^{CODESYS Forge talk (Post)}
Hallo Herr Schwellinger, vielen Dank für die Antwort. Leider hat auch das weglassen des "sudo"-Befehls kein Erfolg. Folgendes passiert: Bild 1: Befehl in der Konsole eingegeben ohne sudo; Uhrzeit wird nicht gestellt (keine Berechtigung). Bild 2: Befehl mit sudo ausgeführt, Uhrzeit wird gestellt. Bild 3: Befehl ohne sudo von CoDeSys aus ausgeführt; Rückgabewert gibt die Uhrzeit an, die eingestellt werden sollte, Uhrzeit wird jedoch NICHT eingestellt. Haben Sie noch eine Idee was es sein könnte?

Post by elektron785 on CAN-Bus in Demo-Version ^{CODESYS Forge talk (Post)}
Hallo, wie verhält es sich mit der Demo-Version und Datenübertragung z.B. via CAN-Bus. Der Bus läuft, das Device befindet sich im Zustand "Operational" aber es werden keine Daten von der Soft-SPS empfangen. Ich benutze aktuell eine nicht lizenzierte Version von CoDeSys Control for Linux ARM64SL. Normalerweise sollte die Demo-Version uneingeschränkt laufen - also kann ich davon ausgehen, dass es sich um einen Programmierfehler handelt oder ist die Feldbusfunktion ohne Lizenz doch in irgendeiner Form eingeschränkt verfügbar (außer dem 30 Minuten Limit nach Reboot)?

IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...

Hi, Similar problem, I have license for Raspberrypi Control MC SL. It didn't work with version 4.10.0.0. I have now instaled new version 4.11.0.0. Raspberrypi Control SL. The same behavior, runtime works sometime several minutes, sometime only several seconds. The second problem is with license. There isn't available any runtime MC SL on Codesys shop, not even older version 4.10.0.0. Is it only temporarily or, MC SL will be not available more for rpi?

Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.

Hi, jain. wir haben mit IFM gesprochen. Sie sagen es liegt an Codesys selbst. Die Daten seien anscheinend nicht konsistent wenn das Projekt zu und erneut geöffnet wird, sei ein probkem von SP11. IFM wird im Sommer ein neues Package rausgeben wo sie auf eine neue CS Version wechseln, dort soll das Problem dann behoben sein. Wir haben zwar einen Workaround rausgefunden aber jenachdem was du in der Safety treibst geht dieser dann nicht mehr. schreib mir zur not eine PN wenn du mehr wissen willst.
