Post by tcarlbom on Read tag values using external program ^{CODESYS Forge talk (Post)}
This is my first time posting in this forum and I am new to codesys. I am a fullstack developer and I am trying to figure out how the following. What would be the best approach to create a own/custom tag browser? Either directly in codesys ide or using a separate custom program (perhaps a winforms application). 1.a. Shall I parse the .project xml file to get a list of all tags in the project? 1b. Shall I use python scripting in codesys ide to get a list of tags? Once one have selected some tags. These tags shall be exposed to a python program which will be acting as a edge computer. It’s fine to be able to import a file. 2a. I found a library called codesys plchandler which (as I understand) acts a rest api server. Is this correct? If so, can I query the api from a custom python script, ie can query what tags exist in project and or read tag values? My research so far. From earlier projects I know that using opc ua would be perfect for this but from my opinion it’s bloating the plc since it’s resource intensive. So opc ua is not an option. Codesys automation server is neat. But I don’t want to rely on some cloud services and subscription based pricing. There seem to be several interesting codesys libraries like mqtt, tcp server and NVL sender which would help me expose plc tags. But all have a common problem. One have to manually write what tags which will be used in these function blocks. I want a similar experience like “selecting” tags in the opc ua or the codesys tracing, ie a tag browser.

Post by mucleus on What is the solution for "Application stopped on recovery switch request"? ^{CODESYS Forge talk (Post)}
Hi, everyone. I am using CODESYS RTE and Profinet I/O or EtherCAT I/O. Occasionally (once every 1-2 months) the attached image occurs and the program stops. I want to know why this phenomenon occurs and how to solve it. I attached log. Please help me. Thanks.

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'

Post by maxkemmeren on PFC200 (750-8214) high linux load average, but seems random. Possibly EtherCAT related. ^{CODESYS Forge talk (Post)}
Have you received any feedback or found any solutions to the load problem. We are running into similar issues, even without codesys running the load avarage is above 1 meaning that it is to busy already without plc code running. Hope you might have some more insight.

At the moment there are some changes on PI OS, which lead to problems with the PI5 an Pi runtime. I would use Arm SL or Arm 64 SL as runtime depending on which OS you have installed. just use the CODESYS Installer and deploy the the Arm runtime.

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by jmfernandes on OpenDir always in error ^{CODESYS Forge talk (Post)}
Thanks for the answer Tim. I am using the codesys version 3.5 SP16, is this also affected or only after version 19? But now at leastI know that is an acess problem to the file and not something else. Unfortunately the link you posted on 2023 are now dead, but I will investigate!

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

Post by bjarne-pagaard on Unable to add alarm configuration object to project ^{CODESYS Forge talk (Post)}
I believe it should be available. It may be the case, that your device does not support the alarm configuration. Some smaller PLCs sometimes do not support it. You can try changing to a different device, like a Codesys Control Win, in your project, and see if then allows you to add the alarm configuration.

Moin zusammen, ich habe vor die OPC UA-Verbindung dynamisch einzubinden und es auch nach der Codesys-Anleitung probiert. Dabei hatte ich aber das Problem, dass ich zusätzlich zu den Config-Variablen auch noch eine statische URL angeben muss, was dann aber den Sinn der dynamischen Vergabe verfehlt. Hat dazu schon jemand Erfahrungen gesammelt und kann mir vielleicht Tipps geben, was ich noch beachten muss? LG Denis
