Post by e13740e on Parameterized Property syntax for array element processing ^{CODESYS Forge talk (Post)}
Hello. I'm trying to create a Parameterized Property(CDS V3.5 SP21) to avoid copy-pasting code for processing array elements. I can't seem to get any result. Perhaps I am making a mistake with the syntax. None of the declaration options below are accepted by the compiler. If you know and use them (Parameterized Properties) in your work, please let me know. Thank you in advance. Option 1: PROPERTY <property_name> : <data_type> VAR_INPUT <index_name> : <index_type>; // One or more index parameters are declared here END_VAR</index_type></index_name></data_type></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY Option 2: PROPERTY <property_name> (<index_name> : <index_type>) : <data_type></data_type></index_type></index_name></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY

Post by valenting on Runtime not working on raspberry pi Bullseye ^{CODESYS Forge talk (Post)}
Hello I have a problem with Codesys on Raspberry pi with Bullseye The device is not recognized as a Raspberry pi, as I get this error : ooops... this runtime was built for RASPBERRYPI. Hardware version or firmware version not supported! (-18, 0x00000BB8, 0xFFFFFFFB) I'm running Codesys on a compute module 4S with Raspbian GNU/Linux 11 (bullseye), my kernel version is Linux 5.10.90-v7l+ Codesys version is the latest, released last week (4.11.0.0, CODESYS Control V3.5.19.61 for ARM-32Bit - build Feb 22 2024) I know it works on the same device if I use Raspbian 10 (Buster) with Linux 5.4.81-v7l+ kernel, but for some other reasons I have to use Bullseye. What can I do ?

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Hello, I'm trying to understand the reason for the many errors on the EtherCAT master status page. If we set the cycletime to 1ms we see a lot of rxerrors and lostframes, but the send and recive times are quite good (see attachement). And the status of the EtherCAT bus is good (no other errors, all is green, slave has no errors) But when we set 2ms cycletime the lostframe errors are gone, but periodically increses rxerror counter (see attachement). The questions is, what do these errors actually mean and what we can do to get gid of them? Linux RT, imx8, Codesys runtime for ARM 3.5.21.10, Ethercat 4.10 Thanks

Post by dkugler on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
you can give this code snippet a try. It's extracted and simplyfied from my code: Install VisuElemBase lib if not installed yet. Execute in visu task: VAR pClientData : ARRAY [-1..100] OF POINTER TO VisuElemBase.VisuStructClientData; END_VAR VisuElemBase.g_ClientManager.BeginIteration(); pClientData := VisuElemBase.g_ClientManager.GetNextClient(); WHILE pClientData <> 0 DO pClientData[pClientData^.GlobalData.GlobalClientID] := pClientData; END_WHILE You have to make shure every no longer updated pointers in the array have to be deleted and no longer used by your code! Usage of this pointer access at your own risk :-) Works with SP16. From SP17 and newer there will be warnigs etc. using this solution as I remember. It will be great, if Codesys publishes a example or give a hint how to accesse this client values with the VisuUtil lib or other future-proof way!

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 bingo on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Suppose you need to switch PLC IP dynamically between 192.168.1.10\192.168.2.10, First, set PLC IP to 192.16.1.10. Create a PGVL with a flag ‘xUseSecondry’ xUseSecondry : bool ; create a function that use socket to update IP: FUNCTION fSwitchIP : bool VAR_INPUT useMainIP:bool; END_VAR --------------------------------CODE------ if useMainIP then SysSockSetIPAddress(‘0’, ‘192.168.1.10’); PGVL.xUseSecondry := 0; else SysSockSetIPAddress(‘0’, ‘192.168.2.10’); PGVL.xUseSecondry := 1; end_if Now, if during execution, you need to switch IP, call the function ‘fSwitchIP()’, Set input to 1 for main IP, 0 for secondary IP. In order to set secondary IP at startup, you can do the following: in your PLC_PRG add a flag: xInit : bool := 1 ; and the code: if xInit then if PGVL.xUseSecondry then fSwitchIP(0); end_if xInit := 0 ; end_if *Alternative way is to use system events.

Post by dkugler on CoDeSys V3.5.19.7 Code erzeugen dauert extrem lange ^{CODESYS Forge talk (Post)}
Ich hatte einige Jahre Codesys in einer VM laufen. Das habe ich vor allem wegen den sehr langen Compilierungs- und "Projekt speichern"-Zeiten wieder aufgegeben. Mein Hauptprojekt hat eine Größe von 14MB, erzeugter Code ist bei 20MB und enthält über 50 Visualisierungsseiten. Bei mir dauert das Code erzeugen mit SP20 P4 ca. 1 Minute. Mein Laptop ist ein i7 3.1GHz 16BG RAM und 5-6 Jahre alt, also wahrlich keine Rennmaschine. Ich denke dass die Übersetzungszeit extrem vom Projekt, den notwendigen Bibliotheken, Virenscanner(temporär abschalten, besser? schlechter? gleich?), gleichzeitig laufende Windows-Programme etc. abhängt. Ich schließe generell während dem Programmieren alle anderen nicht absolut notwendigen Anwendungen, um Codesys den Zugriff auf möglichst viel RAM und CPU-Leistung zu ermöglichen. Viel Erfolg bei der Suche nach dem Flaschenhals!

Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

Post by ac-spr on Runtime variable that indicates a user is online to the code ^{CODESYS Forge talk (Post)}
Looking to access a variable at runtime that indicates a user is online to the code. essentially want to use this value to feedback to the user on the HMI. we use turck and bosch rexroth devices if this information helps. I was hoping there was a variable at the application level, or a library that could be used but I was unable to find anything. I know there's a pop up when you try to login/ go online to the code when a user is already logged in, so the system does provide an indication that it knows already online, but has no access to a value from what I can see. Any help is appreciated

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?

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?

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?
