Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
Thank you very much for the quick answer! The RPi hw were delivered last week so it's probably a resent version. I found an old scrapped board (2 years or so) with a broken GPIO that I tested with the same SD card image and with that board Codeys can run for the full 2h demo period without issues. Then I went back the the new board to test the 4.17.0.0 release but the installation fails... [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesyscontrol started [WARNING] Unable to detect Raspberry Pi Architecture. Setting armv6l as default, you can change this through the settings panel. [INFORMATION] Standard output: codesyscontrol stopped [ERROR] Expected exit value of command failed: expected 0, received 1 [WARNING] Error setting the Raspberry Pi Architecture [ERROR] Error installing codesyscontrol Do you have any idea what could be the reason? I'm using an OS image including Python drivers for LCD and some I/O:s from last year to keep things stable, but also after upgrading with sudo apt update && sudo apt upgrade I still get the same error Reverting back to 4.15.00 works fine: [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesysedge started [INFORMATION] Successfully installed codesyscontrol [INFORMATION] Successfully started CODESYS Edge Gateway for Linux [INFORMATION] Successfully started CODESYS Control for Raspberry Pi SL but as before the Codesys services stops after 30 seconds. And I noticed that the Codesys control stops and is not reachable also if I have no application loaded.

Post by tariq on Using Hilscher CIFX Cards as EtherCAT Masters in CODESYS ^{CODESYS Forge talk (Post)}
Dear Codesys Support Team, I hope this message finds you well. I am currently working on a project that involves using a Hilscher CIFX card to act as an EtherCAT master within the CODESYS environment. Despite following the available documentation and setup guides, I have encountered some challenges and require assistance to ensure proper configuration and operation. Questions: 1- Could you please confirm if the Hilscher CIFX card is supported as an EtherCAT master in CODESYS? If so, are there specific drivers or configuration files that need to be installed? 2- Are there detailed setup guides or example projects available that demonstrate the integration of Hilscher CIFX cards with CODESYS for EtherCAT communication? 3- Is there any additional software or plugins required for ensuring seamless communication between the CIFX card and the EtherCAT slaves within CODESYS? Your support and guidance on these matters would be greatly appreciated, as it is crucial for the success of our project. Thank you for your time and assistance. I look forward to your prompt response. Best regards, TB

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, I am using Codesys sp20p3 and IIoT library 1.11. I am trying to test QoS 1 & 2 and I have some issues. I am using mosquitto as the broker. I am also using some other MQTT clients like Node-Red and TwinCAT. They all work as expected for every QoS levels. I only have issues with Codesys MQTT client. In the Codesys client, if I subscribe to a topic as QoS 1 or 2, and a client publishes to this topic, I receive the message. But if I disconnect the Codesys client from the network and a client publishes to the subscribed topic, when I reconnect Codesys client to the network, I don't receive the messages as expected. Also there does not seem to be an auto-reconnect feature. So I have to manually set the mqttClient.xEnable bit to FALSE then back to TRUE in order to reconnect to the broker, then I also have to set the subscribe.xEnable to FALSE and back to TRUE in order to re-subscribe to the topic, but even then, I don't receive the messages that were published while I was disconnected. What am I doing wrong? I set the cleanSession bit to FALSE and I give my client a clientID. With the TwinCAT MQTT Client, I do the same thing and everything works as expected. It even auto-reconnects to the broker. I would expect Codesys MQTT Client to be as reliable as TwinCAT. Maybe I am doing something wrong? I also noticed that when trying to publish a QoS 1 or 2 message while disconnected from the broker, it does not work. In TwinCAT, I am still able to publish. The messages are stored in the client and published once reconnected to the broker. I would expect to be able to do the same thing in Codesys. Is this all possible? Am I doing something wrong? Thank you

Hi, I have a Beckhoff EL6751 EtherCAT / CANopen gateway which fails on the Canbus when the CANopen_Manager is added. Currently no devices are connected to the EL6751. If I add a device, I get the same issue. If I add a device and connect the bus, I get the same issue. Is there something I am doing wrong? Regards Trevor
