I can confirm that at my 4ms EtherCAT Master the frames per second is equal at round about 500 with Codesys SP19. The same program at SP16 it was at 380-430 f/sec. for me it will be interesting too, whats the reason is for this high frame count/sec? I havn't had the time to use a paket sniffer and analyse all the frames. I can't help with your other questions, sorry.

Hi, did you ever figure this out? I am trying myself to find a working hash generator as the Codesys CryptoDemo example does not seem to work.

Are your texts WSTRING? maybe you should try WSTRING versions. I have a vague memory of having to switch to TextListUtils library also.

Post by karel-bas on Loosing connection to emulation running on Linux ^{CODESYS Forge talk (Post)}
Hello, I am trying to emulate my code but for some reason my Codesys IDE keeps loosing connection to the emulator. I am constantly pinging virtual machine on which its running and its running fine, but codesys refuses to reconect to it, and is not able to rediscover it. Codesys 3.5 SP20 Patch 1 I have linux installed like image in attachment.(using version 4.12) Linux VM is set up to use up to 4 cores and 8gb of ram, with nothing else runing on it. I dont have a license so I am aware that the emulation shouldnt run for more then 120 minutes I am able to, login, get sysinfo, reboot etc from codesys IDE for certain period of time (5minutes) then my connection gets lost, sometimes I can login again, but sometimes i have to reboot the VM. Any suggestions what might be the issue ?

BTW - I had a chat with a Beckhoff support engineer. He explained that if you use sync0 and sync1, two frames per cycle are expected.

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 pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

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.

You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Was there ever any resolution to this? I am using Virtual Control SL on a ProxMox setup, and I can't get the license installed. I get the same errors reported above.

Automation Server + Pi Gateway + PLC w/ CAN
Last updated: 2024-09-22

Post by danielbeers on Automation Server + Pi Gateway + PLC w/ CAN ^{CODESYS Forge talk (Post)}
Hello, I have a project using some EPEC PLC's. Some of them are programmable using Ethernet and some use CAN. We currently have a Raspberry Pi that is acting as a gateway to the Codesys Automation Server and is successfully working for the PLC's communicating over ethernet. I am trying to achieve a similar result for the PLC's that have only CAN access. I have PEAKCan drivers on the Pi, and can successfully send/receive messages. But the Gateway does not recognise the PLC when scanned from the Automation server online. Is there a library or service that exists to translate the CAN messaging, to the Edge Gateway, and be able to achieve remote access with the Automation Server? Or is this not possible without creating something custom? Cheers, Daniel
