@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I've also noticed that when I turn off "enp1s0", suddenly the source IP for the ModbusTCP changes to that of "enp2s0", which is what makes sense to me. When I turn it back on, the source IP remains that of "enp2s0".

Post by jkopicz on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
In my project, I have frames that I would like to read the current active index. I change the frame index using the onclick properties of a button, then change frame index. I need to do some logic based on which frame index is selected. Is there a way to read the current active index of a frame?

I tried both 3B en 4. But every time with a lite version. I didn't try the full version of raspberry pi os. Nice to hear you are aware of the problem and trying to fix it. I'll hold on to the image from 2023-10-10 for now.

Post by blitz on SMC_ERROR SMC_CGR_INVALID_POSPERIOD ^{CODESYS Forge talk (Post)}
Codesys - SMC_ERROR SMC_CGR_INVALID_POSPERIOD - Invalid modulo period less than or equal to zero or greater than half the bus bandwidth. Has anyone seen this error and actually understands what it means and how to get rid of it? I tried to work around it by reducing the number of increments on the drive but then the drive itself starts throwing errors.

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Just adding some info regarding the issue above. Logged onto the project using dev3og5 user (see screenshots); appeared to be ok although when attempting to logon to the device message says 'currently not authorized to perform this operation on the device' (screenshot). If user dev3og5 has same permissions as Owner user; why would it not be authorized. I am at a loss; any assistance would greatly be appreciated. Thank you Mike

Post by schnepper on Error building Extension SDK Linux code ^{CODESYS Forge talk (Post)}
I'm installed the CODESYS Control for Linux SL package and am trying to use the Extension API to call a simple C function. When I get to the step to run "make all" on the Linux machine, I get the error: build interface header: out/CmpFirstTestItf.h from CmpFirstTestItf.m4 ERROR: This functionname does not contain _cext (this is mandatory, see help for details): DEF_API(void',CDECL',external_struct__fb_init',(external_struct_fb_init_struct *p)',1,0x1F77E075,0x00000001) Why does "Generate Runtime System Files" create a function that does not have cext in the name? What am I missing?

Post by paro on send appliaction files to wago plc (codesys 3.5) via ssh ^{CODESYS Forge talk (Post)}
Hi, it is enough to copy the files to /home/codesys/PlcLogic/Application and adding the lines [CmpApp] Application.1=Application to the eRUNTIME.cfg, if your Application in your program is also called "Application". Reboot -> Bootapp should be loaded. If not please check the log /var/log/runtime.log There should be a line which explains why the bootproject is not loaded.

I tried to use C code in the library that I have been developing in the project, but without success. I tried to use the CODESYS Control SL Extension Package to generate XXXdep.h and XXXltf.h, but without success. Do you have a better example of how to generate these files and how to compile them?

Hey there! Is it possible to download the "CODESYS Scripting" package outside of the "CODESYS Installer"? Or is there a alternative way to download the python files for the scripting engine? I want to setup a test environment to write test scripts and therefore want to have those python scripts for e.g. autocompletion. Thanks in advance!

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
I changed the interfaces to br0 & br1 as they are designated on the Wago PFC200. That issue is resoved. However, on site I have very high system cpu usage, system as in Linux. Presently it is not known why - my bench system does not exhibit such high system usage. In the past this was due to IGMP network traffic every 250uSec from synchronized inverters.

https://forge.codesys.com/forge/talk/Engineering/thread/632c29cb93/#8d94 The above comment is the best, but if you just want to see it work you can try disabling the distributed clock. It's not the right thing to do but it should resolve that error.

Post by programmierer on UDB Block in Codesys V2.3 implementieren um Werte an bestimmte IP-Adresse zu senden ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich möchte mich hiermit an euch wenden, in der Hoffnung, dass ihr mir bei meinem Problem behilflich sein könnt. Ich bin neu in der Programmierung und arbeite aktuell mit einem Wago Controller in unserem Labor, der eine Wärmepumpe steuert. Mein Ziel ist es, vier spezifische Werte an eine bestimmte IP-Adresse zu senden. Dazu habe ich versucht, in das vorhandene CODESYS-Programm der Wärmepumpe zusätzliche UDP-Blöcke einzufügen, um die Datenübertragung zu ermöglichen. Leider hat das Senden der Daten bis jetzt nicht funktioniert. Ich habe auch Bilder der Blockkonfiguration beigefügt, um einen besseren Einblick in den Aufbau zu geben. Über jegliche Hilfestellung würde ich mich sehr freuen. Vielen Dank im Voraus!

Post by tama00 on Datenübertragung mit SSP0 zw. uC und Raspberry Pi mit Codesys Runtime ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich arbeite derzeit an einem Projekt, bei dem ich einen Microcontroller habe, der Messwerte über die SSP0-Schnittstelle an einen Raspberry Pi senden soll. Diese Daten sollen dann in Codesys für eine Soll/Istwert Vergleich/Regelung verwendet werden, und das Ergebnis soll zurück an den Microcontroller geschickt werden. Meine Frage ist, ob es möglich ist, diese Kommunikation über die SSP0-Schnittstelle (als SPI frame format) zu realisieren, oder ob ich auf eine 'reine' SPI-Schnittstelle des uCs zurückzugreifen muss. Gibt es spezielle Dinge, die ich beachten muss, um diese Datenübertragung erfolgreich in Codesys zu implementieren? Ich wäre sehr dankbar für Ratschläge oder Hinweise, wie ich dieses Vorhaben am besten umsetzen kann. Vielen Dank im Voraus!

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Hi, can you please provide a new example for the topic at CODESYS "Client Independent Visualization Switching" https://forge.codesys.com/prj/codesys-example/client-independ/home/Home/ Since a few versions, the functions used cause warning messages. Examples for the use of all function blocks from the Visu Utils would generally be very helpful! Several people have put together an example here: https://forum-de.codesys.com//download/file.php?id=2240 BR Patrick

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

Post by phoward131 on Alarm Table Filtering ^{CODESYS Forge talk (Post)}
I actually just found the solution maybe. If anyone else is running into this, go to your Project Settings > Visualization > Advanced (check 'Visible' to see advanced settings) > UNCHECK 'Activate property handling in all element properties.' I am not sure what else unchecking this might affect but it seems to allow the alarm table to be filtered as expected.
