Post by timvh on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
Yes, this is possible with the Toolkit. We only server customers in the Benelux that do this, so contact your local CODESYS distributor, or contact the sales team of CODESYS Germany.

Post by ragarcia on How to change login visualization for other visualization after user logged in ^{CODESYS Forge talk (Post)}
Hello everyone, I have a web visualization on Codesys and to be able to use the web visualization first an user and a password is requested. After the user logged in, I want to automatically change the visualization to the 'Home' visualization but I am not sure how to do this. In the login visualization I basically have a button with the input configuration to execute the action 'Login' after a click. Once the user is logged in, the visualization is still stuck in the login page and I want to automatically change to Home visualization if the user was succesfully logged in. How can I know the number of web visualization clients connected to my PLC? Thanks in advance

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

Post by riccardo on Error while processing the visualization: Client id not present or no longer valid ^{CODESYS Forge talk (Post)}
Hallo goodmorning, I am using codesys 3.5 sp19 with Weidmueller PLC. I created a page with several checkbox to manage an array of bool. When I build the project the system doesn't signal any error, when I go in simulation mode everything works until I click on checkbox to toggle the variables. Other visu elements works proprerly (e.g. bottons, lights, ect, ect) but the check boxes cause a crash giving the following error: Error while processing the visualization: Client id not present or no longer valid I serched to figure the problem out and to search a solution on the web but nothing. Can someone help? Thanks and Regards, Scanu

I recently acquired the Opus B4 product from topcon company and encountered a "code 7" error in the Web Visu File Transfer application. I have been unable to locate the CFG files mentioned above. However, I have been able to perform streaming. I would appreciate your assistance in resolving this issue. Sincerely, Emre öZÜPEK

Post by felixm on Unable to select VisuDialogs.Numpad in Open Dialog input configuration ^{CODESYS Forge talk (Post)}
I'm trying to open the VisuDialogs.Numpad dialog to enter a new temperature setpoint on one of my VISU screens. For some reason, the numpad dialog does not appear as an option in the Open Dialog dropdown in my input configuration. I'm very new to CODESYS, so sorry if this is a simple fix/known item XD.

Post by i-campbell on Codesys 3.5 Library Download Failed ^{CODESYS Forge talk (Post)}
You use very old codesys, maybe SP13? the newer sp17 libraries are in a format not compatible with your version. I suggest upgrading everything to at least SP17, but may as well go to SP20 Patch 2.
