Post by nizrahel on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hi all! I'm working on an home project using a Raspberry Pi 3 device with Codesys for Raspberry Pi 64 SL runtime. I would like to create the HMI interface with Siemens WinCC Unified (or Advanced) configuring the Raspberry as OPC UA server. I tryed everything, but I didn't find the way to let the OPC UA connection works using UaExpert. I tryed to use anonymous connection, authenticated connection and the ip address instead of the server name in the path connection. There is no way to connect to the OPC UA server and I was asking myself if this feature is really supported for the runtime version used. Another strange thing I noted, is that is not possible to quickly create an OPC UA certificate in the Security Screen, as show in any tutorials. I have correctly created the Symbol Configuration enabling the OPC UA feature. I attach to this topic some printscreen of the actual configuration (sorry for the italian language interface, but I didn't find the way to switch to english). Thank you very much in advance for your support and advices!

Hello, this seems to be a known issue, but persistent/retain variables don't seem to work properly on RevPi devices. Is there a workaround to this? All I need is for a few configuration variables to be remembered through power cycle.

Good morning! Is there a way to run a python script or something else automatically after CODESYS (3.5) did its build or before download? I am searching for something like the Custom Build steps in Visual Studio. Thank you! Voffi

I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

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

Hello, I was wondering if there was further documentation on the SharedMemory library in CodeSys outside of the code example provided, or maybe a way to access the source code of the shared memory implementation. Thank you in advance for any advice. - Viktor

Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.

Well still similar questions remain. I don't know of "CmpRecoverySwitch" and the only thing google has to offer is your xml file. I think you'd need to provide a lot more info before anyone makes much effort here.

Post by drml on Array to String ^{CODESYS Forge talk (Post)}
If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?
