Post by installwhat on Opc remote alarms on Linux box ^{CODESYS Forge talk (Post)}
It seems that the hmi sl license only works with windows. If i'm happy using web visu, rather than target visu, is possible to use remote opc-ua remote alarms without the hmi sl? Maybe it can be included in a different license that works on Linux? thanks

Post by narius on OPC-UA object instances preexisting in imported xml information model ^{CODESYS Forge talk (Post)}
Hi all, is it possible to use object instances that are not instantiated by codesys itself, e.g. have been defined in UA-Modeler ? When I browse the plc with UA-Expert I see those instances, but I have not seen information in codesys or the web if these are writable in codesys. So far, I am under the impression, that it is not possible, but would like to hear from others. Also, is it correct, that it is not possible to create references inside codesys ? Thanks in advance and kr

Post by thn-power on Updating OPC UA Core Nodeset on PLS ^{CODESYS Forge talk (Post)}
Hi After much trail and error I think I found the root cause to my OPC UA problem. The problem is that I cannot manage to build and download a program with a a custom OPC UA Information model. We use a Weidmueller WL2000 PLS, but the problem also exsist on the Win V3 PLC. Our custom information model is based on the latest versions of the OPC UA Core Nodeset v 1.05.03 (2023-09-20) and UA/DI nodeset 1.04.0 (2022-11-03) Those nodesets are installed in the Codesys Information Model Repository (3.5.19.6) However, when trying to build I get the following error. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://bos.org/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/DI/ is required by http://bos.org/ with a minimal publication date from 03.11.2022 but the device has only a model from 09.03.2021 installed. Probably the information model from 09.03.2021 is missing in the information model repository. Build complete -- 2 errors, 1 warnings : No download possible I think the problem is that the UA Core nodeset is implemented in the PLC firmware (at least that in Siemens S7), and that only includes the "old" nodeset from 2021-09-21 etc. So the question is, how (or if?) can I transfer the new nodeset to the PLS? I have created separate Information models under Communication manager with the newer code nodesets (UA and DI). But it seems that the compiler does not recognize them being excising, neither in the Codesys IDE or on the PLC. Would have guessed that this is a common issue, sine many manufacturers use the latest versions of the OPC UA standard, and that it would be a solution to the problem.

Post by anlebr on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying use the Codesys Communication Manager to set up an Opc ua server with a custom information model. As a start I am using the Boiler model available on Opc foundations github page. I am testing with a Wago CC100 and using Codesys V3.5 SP19 Patch 6. I get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://opcfoundation.org/UA/Boiler/ with a minimal publication date from 15/12/2023 but the device has only a model from 15/09/2021 installed. Probably the information model from 15/09/2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway, both versions are available in the repository. How can I solve this?

Hi yr00, the default sampling interval is set to 1s. you can generate your own client settings, this link should help you:- https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html

I had some help from Codesys to debug this problem. It seems there was a problem within the target (a bug?). I only used for a proof of concept. Possibly it will work with a new version of the target

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
So I found the mistakes. First I forget to deactivate "Use access rights defined in the user management". And also I used in "UaModeler" a project name with whitespaces, which lead to a wrong namespace name.

I also had this problem connected CODESYS to UAExpert for the first time. In the device, I need to allow anonyomous log in. Follow steps 14 - 17 of the following tutorial: https://docs.factoryio.com/tutorials/codesys/setting-up/codesys-opc-ua-sp17/#creating-the-project

Post by karel-bas on Loosing connection to emulation running on Linux ^{CODESYS Forge talk (Post)}
Ok. I ran the vm twice until it failed and from log it seems like my OPC UA fails becouse I am not able to get HTTPs certificate ? I dont really see any other reason.

Post by gediminas on Datasource OPC UA client system failure ^{CODESYS Forge talk (Post)}
I haven't actually found an answer yet. It happens quite rarely, so testing and diagnostics are complicated. I've updated the software with every SP and add-on updates released, but it's probably a Kernel driver issue.

Post by timvh on Where to find the OPC-UA Information Model Repository ^{CODESYS Forge talk (Post)}
I'm not sure, but maybe you need to install or update the "CODESYS Communication" add-on through the CODESYS Installer.
