Hi, Is there a way to run --runscript in linux system? This help only explains how I can run --runscript by using .exe. I would like to run script inside linux system and retrieve variables in codesys via CLI. https://help.codesys.com/webapp/_cds_starting_script_via_command_line;product=codesys;version=3.5.17.0

Post by joachimk on Profinet Controller IP-Adresse ändern ^{CODESYS Forge talk (Post)}
Die IP-Adresse des Profinet-Controllers soll zur Laufzeit geändert werden. Dabei handelt es sich um eine Anwendung auf einem PC mit einer Standard-Ethernetschittstelle (ControlWinV3+WinPcap). Die Datei "CODESYSControl.cfg" wurde dazu angepasst: .... Adapter.0.Name="Ethernet 4" Adapter.0.EnableSetIpAndMask=1 Die konfigurierte IP-Adresse wird zur Laufzeit an die tatsächliche IP-Adresse der Netzwerkschnittstelle mit dem folgenden Befehl angepasst (die Änderung von 192.168.2.33 auf 192.168.2.34 funktioniert auch): Ethernet.UpdateConfiguredIPSettings(IpAddress:=Ethernet.IPAddress, subnetmask:=Ethernet.Subnetmask, gateway:=Ethernet.GatewayAddress); Der Profinet-Controller geht danach auf Störung und gibt die folgende Fehlermeldung aus: "Controller-Status: currently active IP does not match the controller's configuration" Unter "Ethernet diagnostic information" kann man die geänderte IP-Adresse von 192.168.2.34. Ethernet läuft auch ohne Fehler. Unter "PROFINET IO Driver diagnostic information" -> "IPParameter" sieht man noch die alte (konfigurierte) IP-Adresse 192.168.2.33. Wie kann man die Störung beseitigen? Leider habe ich keine Methode zum Ändern der IP-Adresse auf dem Profinet-Controller gefunden? Reconfiguration des Profinet-Controllers?

Post by koppit on SysComRead Timeout Parameter ^{CODESYS Forge talk (Post)}
Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

Colleagues, i have the same problems. At the current time, I have to use the new version of the Codesys (3.5.20.10) + Control for Linux SL 4.11.0.0, but it works unstable : theree are a lot of freezes and not-respondings. I tested this on different projects: those that were created in the current version of the project, and those that were migrated from other versions of the development environment. Compiling a project without connecting to a controller is fast enough. The first downloading of the code into the controller, too. But as soon as you need to make edits and download a new code problems begin. Codesys "freezes" at the "Generation code" stage for 15-20 minutes. And only after that time loads the code into the controller. Previously, we used version 3.5.17.60 + Control for Linux SL 4.7.0.0. The process took 1-2 minutes. Do you have any ideas how can i fix it? I will be grateful for your answers.

Post by sajid on NMEA Serial data read in Control win v3 x64 ^{CODESYS Forge talk (Post)}
I am using the SerialCom example program from the CODESYS website to read NMEA strings in CODESYS Control Win V3 x64 through a serial-to-USB converter. However, I occasionally receive only partial data or encounter errors in the received string. A screenshot of expected NMEA string attached for reference. Could you please advise on how to ensure the full NMEA string is received consistently? Error in strRead variable is <value of="" the="" expression="" cannot="" be="" retrieved=""></value>

Post by xcqt on Oop best practice ^{CODESYS Forge talk (Post)}
Hi all, I’m currently trying to improve my OOP structure in CODESYS and I’m looking for some input on how others approach this. I understand the basics like inheritance, interfaces, abstract FBs, methods, and properties, but I still struggle a bit with the overall architecture and what’s considered clean or scalable in bigger projects. As an example, I’m working on two different energy meter function blocks: FB_EnergyMeter_MQTT reads data from MQTT (strings) FB_EnergyMeter_Modbus reads data from Modbus (words) Both have their own Update() method and implement the same interface (something like IF_EnergyMeter). Later on, I’ll probably add more meter types, but they should all behave the same from the controller’s point of view. Now, there’s a FB_GridControl block that needs power data from these meters. I see two options here: Define the meter blocks inside FB_GridControl and call them directly (for example fbModbusMeter.UpdateModbus()). Keep the meter blocks outside and pass them into FB_GridControl as interface references, so the control block doesn’t know which specific type of meter it’s dealing with. Option 2 feels cleaner and more flexible to me, but I’m not entirely sure how to handle the data flow in that case. Should I pass the meter instance through an interface reference (REFERENCE TO IF_EnergyMeter)? Or is there a better way to link the external FBs to the control block? I’d like to hear how you structure this kind of setup or see an example from someone who has done something similar. EDIT: I think i need to do something like this fbModbusUpdateInput(wInput:= wWordValue); fbMqttUpdateInput(strInput:= strStringValue); IF bUseMqtt THEN Meter REF = fbMqttUpdateInput; ELSE Meter REF = fbModbusUpdateInput; END_IF fbControl.SetMeter(UsedMeter := Meter); Or am i thinking wrong? Thanks, Thomas

Post by etalp on Eaton XC303 firmware update via USB ^{CODESYS Forge talk (Post)}
Hi, I'm struggling with updating my xc303 to firmware 3.5.17. It is possible only via USB port. I've installed proper update files on the USB then plug it into the PLC's USB port and restarted the device. Shortly after LED's on the PLC started to blink, so updating process has started. But after 10 minutes the PLC LED turned off and after all I could't serach for this PLC in Codesys, but could ping it. Could someone eplain to me proper procedure of updating the fimrware in XC303 via USB? Is it neccesary to STOP the PLC switch after pluging the USB?

You need to ask Weintek if they support the licensing. For Softmotion the device should be realtime capable.

Post by dekelec on Request for IFM ecoPlus21 installation package ^{CODESYS Forge talk (Post)}
Hello, I’m looking for the ecoPlus21 development environment used with early IFM controllers (e.g., CR0020_Q firmware). We have an old project created in ecoPlus21 that cannot be opened in CoDeSys 2.3, and IFM no longer provides this software. If anyone still has the ecoPlus21 installer or knows where it can be downloaded, please let me know. It’s needed only for recovery and migration of an existing project. Thanks in advance,
