Hi Till, Sadly I did not get any feedback on this and was not able to get it to work using Visual Studio Code. I believe I have used a Codesys environment to get something up, but I cant remember any specifics, its too long ago. Good luck with it! Kind regards, Jan

Post by pietrobalint on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi micik, I am not sure I am using well the code, because I checked the directory and there is no retains.ret file. Now I deleted the code from my project and the values are still works as persistant variables after ssh reboot it seems to me they retain as their previous value. So I am a bit confused, maybe 4.12.0.0 Raspberry Pi SL solved the persitent variable problem...

Post by gabrielarffa on Modbus TCP/IP having problems with global variables ^{CODESYS Forge talk (Post)}
I'm using Modbus TCP/IP to communicate Codesys with Elipse E3 as the master for a college project. I have made a list of global variables to organize the programming in two different POUs. The problem is, when I try to do the mapping of variables, the program informs me of an error due to the identifiers having a "." on their names. Do I have to reorganize my code to make it an unified block or is there a way to declare their names without changing all the code structure?

Post by yuan on Seeking a Code-Based Solution for EtherCAT Slave Dropout or Master Errors in Production (Beyond Software Hot Reset) ^{CODESYS Forge talk (Post)}
I need official assistance with the following issue: During EtherCAT communication, if a slave station drops off the network or the master station encounters an error, the problem can currently only be resolved by performing a software-based hot reset. In actual production environments, this approach is unacceptable. Is there a method to resolve these issues programmatically, through code?

Post by k4zz on Continuous Build Server ^{CODESYS Forge talk (Post)}
Hallo Martin, Thank you so much for the Code example. It works really fine for .porject Types. However, I encountered a challenge when attempting to apply it to .library Types. I also tried the option to "Perform static analysis automatically after compilation" # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code() Could you please offer any insights into why this might be occurring?

Post by k4zz on Statisch Code Analyse ausführen via Python ^{CODESYS Forge talk (Post)}
Derzeit arbeite ich daran, statische Codeanalyse in unsere (CI/CD)-Pipeline zu integrieren. Konkret habe ich die statische Codeanalyse erfolgreich für .project-Typen durchgeführt, und sie funktioniert einwandfrei. Allerdings habe ich Schwierigkeiten bei der Ausführung derselben für .library-Typen festgestellt. Hierbei habe ich zwei Methoden ausprobiert: system.commands["staticanalysis", "run"].execute() # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code()

Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Post by umair on Code for reading 4 address to get 1 value of sensor (Ethernet IP) ^{CODESYS Forge talk (Post)}
Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

Post by thomasgaab on EVC - issues assigning variables from VarGlobal lists ^{CODESYS Forge talk (Post)}
Updated the Codesys Safety SIL2 package from v3.5.18.1 to v3.5.22.10 Codesys Version 64 3.5.18.0 After the update the assignment of variables from different VarGlobal lists was unstable. Selecting one group could cause another group to be deselected after code generation. I was unable to perform a compilation were all variables maintained the selection after code generation. Rolled back to the older version and the issue seem to be mostly solved.

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?
