I am looking for the same thing, I am trying to edit a library I downloaded but I found that the functions are read only. The link above is broken, should I be looking somewhere like here? https://content.helpme-codesys.com/en/LibDevSummary/index.html

In fact, specifying to use SM3_Basic library in version 4.14 fixes the issues, choosing 4.16 raises the same issues. (Library Manager > Place Holder > Double click on SM3_Basic > Show all versions)

Thank you seoerr for your suggestion. When I implement that line, I get this error: ** [ERROR] 'OSCAT_BASIC.ARRAY_SDV' is of type FUNCTION and cannot be instantiated** Any other thoughts about instantiating these sections of the library which seem to be provided as source only?

Post by jroddball79 on PM556-TP-ETH — How to change IP address without overwriting the PLC program? ^{CODESYS Forge talk (Post)}
Hi, I need to change the IP address of an ABB PM556-TP-ETH using ABB Automation Builder. The situation is: I have connectivity to the PLC using the current IP (configured in Communication Settings) Online Login works fine The Network Scan does not detect the PLC IP-Configuration tool shows all fields disabled I don't have the original project source, only an empty project The PLC has no SD card inserted The Online menu does not show an Upload option When I modify the IP in the project and connect, Automation Builder shows: "The PLC configuration needs to be updated. A full PLC download is required" I'm afraid a full download will overwrite the running program. Is there any way to change only the IP address without overwriting the application? I'm also open to solutions using third-party tools, Python scripts, or any other method (DCP protocol, direct TCP communication, etc.) as long as it doesn't overwrite the running application. Thank you

Maybe shared memory is an opinion for you to give it a try: https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_shared_memory_communication.html

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Make sure the number of bytes matches the values in the Ethernet/IP>Assembly Information section of the Wagos web management page (expand by clicking on the +). The EDS file will probably have defaulted to assemblies 101 and 104. If you want a different assembly there is an article that tells you how to modify but seems to be unavailable at the moment. An alternative is to modify the .eds file to change the default assemblies.

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, one more point. I have been able to create Property of Text which is added to Global text list so it´s fine. But as soon as I use Frame configuration I lose all other properties but some very basics. I need to have still possibility to set Input configuration because my element is Button. Do you know how to make visible all standard properties + my own properties created in Frame configuration? Thanks a lot. M.

Post by dhumphries on Control for Linux SL on Ubuntu Core ^{CODESYS Forge talk (Post)}
Try using a password instead of a public key to log into the controller. I have a video showing how to do this on a default installation of Ubuntu server, it should work the same for Ubuntu Core. https://youtu.be/rj0dOhgnGjs?si=352PmveEP7JXZnO- I sign in to the controller at about 6:40 in the video. I have never tried to remove the public key and revert to signing in using a password, but it looks pretty straightforward https://askubuntu.com/questions/745423/how-to-turn-off-password-less-login-for-ssh

Post by caliberbishop on Having trouble using the Web Client SL library ^{CODESYS Forge talk (Post)}
Hello, I'm trying to use the Web Client SL library, I installed it in the IDE (did not purchase a license yet, as this is still a proof of concept so demo mode is good enough) and added it to the library manager. However, when trying to define a FB of the type WebClient I get a "Identifier 'WebClient' not defined" error message, setting the type to Web_Client_SL.WebClient did not work as well. Opening the example project the FBs defined there give the same error message. From the problem in the example project I deduce this is not a syntax problem, so maybe a license problem, but there should be a working demo mode, so what am I missing? IDE v 3.5.21.30 Library v 1.12.0.0 Thanks
