Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
Hi, I want to use two OneWireMaster on a Raspberry Pi5. I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0. Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27. Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs. The two masters are 'w1_bus_master1' and 'w1_bus_master2'. In Codesys I've configured to OneWireMasters with the corresponding file paths. But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work. Status is showing "OnewireMaster : Not running" What am I doing wrong? Does Codesys on Raspberry support multiple OneWireMasters? Any help is appreciated.

Wanted to play a bit with a raspberry Pi 4 Model B HW 1.5 and Codesys. Regardless of the image (tried 32bit / 64bit version from Raspberry Pi Imager) and with all tested Codesys Control versions (4.2.0, 4.8.0, 4.10.0) and regardless if single core / multicore / 64 bit variant, always is the runtime stopped after about 30sec with the nice message: ooops... this runtime was built for RASPBERRYPI. Hardware version or firmware version not supported! (-7, 0x00000BB8, 0xFFFFFFFB) Whats wrong with it?!?!? I read a lot about the issue in topics from 2020-2021 but it always was stated with new Codesys control version issue will be fixed (4.4 for example) but still it is there.

Post by cedriclee on RaspberryPI reconnection error ^{CODESYS Forge talk (Post)}
"Hello, I'm Cedric Lee, a PLC engineer based in Korea. I'm reaching out about an ongoing issue with the connection when attempting to control Beckhoff modules using Raspberry Pi with CODESYS for the first time. I use CODESYS to target the Raspberry Pi's IP, install version 4.10.0.0 of the CODESYS Runtime Package, and upon pressing Start in the Runtime, the target connects to the Raspberry Pi. However, within about a minute, an error window appears, stating 'no connection to the device. please rescan your network,' leading to the disconnection of the target. This cycle repeats. I've attached some pictures for your reference. I'm using CODESYS Development System V3, Raspberry Pi 4 Model B (installed as 64-bit), and Beckhoff EK1100 modules. If anyone has a solution to this issue, please help. Your assistance is greatly appreciated."

Open the CODESYS Installer. Create an export file from your current PC from your current version. Then on the other PC Open the installer and install a new version based on the same essentials version, but additionally select the export file which you have created on the first PC. Or just install (import) it within the already existing version. For the installer, you can install it from: https://store.codesys.com/en/codesys-installer.html For help see: https://content.helpme-codesys.com/en/CODESYS%20Installer/_inst_install_setups_and_addons.html On PC 1, save the project as projectarchive (which will then include all the libraries and devices). Then extract this projectarchive on PC 2.

Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge talk (Post)}
I’m currently working on establishing a TLS connection with an MQTT broker using the MQTT Client SL package in CODESYS. While I’ve successfully established communication with the broker without TLS, I'm encountering issues when trying to enable TLS. In the 'MQTT Explorer' application, I can easily upload the server certificate (.crt), client certificate (.crt), and client key (.key). However, in CODESYS, I can’t find a way to upload my client key (.key file). Here's a summary of my current setup: Certificates: I have uploaded both the client and server certificates to the certificate store under the 'Trusted Certificates' folder in the security screen. TLS Context Initialization: Despite setting the _sCommonName as the name of my client certificate, a new self-signed certificate is created and placed within the device’s certificates. I then need to manually move this certificate to the trusted certificates folder. This results in three certificates in my trusted certs folder: client cert, server cert, and the newly created cert. _ciDefaultCertInfo : MQTT.NBS.CERT_INFO := (psInfo := ADR(_sCommonName), udiSize := TO_UDINT(LEN(_sCommonName))); // CN of the certificate (common name) _sCipherList : MQTT.NBS.CIPHER_LIST := STRUCT(psList := ADR('HIGH'), udiSize := 4); // Cipher string see https://www.openssl.org/docs/man1.1.1/man1/ciphers.html _tlsContext : MQTT.NBS.TLSContext := ( sUseCaseName := _sCommonName, // A certificate is stored in the certificate store with the use case name. You can choose any name. Here we use the common name. ePurpose := MQTT.NBS.PURPOSE.CLIENT_SIDE, // For client certificates set this to NBS.PURPOSE.CLIENT_SIDE sTLSVersion := '1.3', // The TLS version sCipherList := _sCipherList, // Set the cipher list sHostname := sHostname, // The hostname of the broker udiVerificationMode := 2, // 2 => Active Peer verification ciCertInfo := _ciDefaultCertInfo, // Set the cert info itfCertVerifer := 0); // 0 => No Verifier mqttClient : MQTT.MQTTClient := (xUseTLS:=TRUE, itfTLSContext := _tlsContext, itfAsyncProperty := _asyncProperty); Additional Details: In the client FB, I’ve set uiPort:= 8883, xUseTLS:= TRUE, and configured itfTLSContext as mentioned above. The certificates are encrypted with SHA256RSA. sHostname is the IP address of my broker. I’ve attached a copy of the client FB, which shows straight lines where variables are assigned and boxes where they are not. I am currently trying this on the only 2 compatible versions of COSDESYS with my controller (V3.5.15.20 and V3.5.18.40) My Question: How do I correctly set up this mTLS connection? What might I be missing? Any guidance or suggestions would be greatly appreciated, especially considering I’ve already successfully established a non-TLS connection with the same broker. Thank you in advance for your help!

Post by orbis-tertius on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Is there anybody can help me with the same problem? I have to migrate created project in ver.3.5.17.0 32BIT with runtime 4.7.0 to ver.3.5.20.0 64BIT with runtime 4.7.11.0 due to the new license. All the libraries and dependencies are updaded and there are no any errors. The first compilation and loading to the controller is being compleated well. After this being done and if I am forced to change any values or change any code in the current project, another compilation will be freezed. This problem can be solved if pressed Build/cleen or cleen all. There is another method to solve this; if project is loaded with excluded object (Alarm Configuration), repeated compilations will be done well.

I couldn't exactly solve the file transfer when I wanted to do multiple transfers while the compiler was open in a way that I couldn't understand. Notification from target: runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! * details of the target component that sent this notification: [CmpName=SysExcept, CmpId=0x00000103, ClassID=0X0001008, ErrorID=0X00000001, InfoID= 0X0000000j] I see the warning. I couldn't find out why error code 4 is coming or what kind of measures I need to take to prevent it from coming within the application. Can you help me? regards Emre OZUPEK

Post by bmatlove on Re-create CoE online window in Visu ^{CODESYS Forge talk (Post)}
Hello, I am trying to re-create the CoE online window within a Visu for purposes of checking and interacting with device parameters occasionally for maintenance purposes. To minimize reliance on using the IDE for misc interactions. Ideally, I would like to exactly mimic the CoE online window within the IDE. I assume that it uses a few tricks to minimize overhead, such as only polling registers which are within the visual scope, for example. I'm afraid it might be too much to ask for a pre-built drop-in Visu module to exist for this task. Do I have any options aside from manually re-creating all the logic to do this, relying heavily on SdoInfo function blocks? Is there a way for me to reference the device ESI file to shortcut the process of determining how many registers there are and getting the address for each?
