Which plc type is it: Either use Automationserver to do this or save the project archives instead of projects or use the source dowload function and reopen the application from plc. So you need to chose one of them.

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

Post by micik on Start Codesys project and then execute python script from command line ^{CODESYS Forge talk (Post)}
Hello, by searching the forum, I have found an example of batch script that can be used to start codesys projct by temporarily setting env variables. However, I'm not sure how to modify this to start Codesys 3.5.20 and whether or not I need to specify "profile" with Codesys version at all. @echo off SET PROJECT=D:\TestScripts\Data\OnlineTest.project SET VARIABLES=POU.testint,POU.testoutput start /wait CoDeSys.exe --profile="CoDeSys V3.4 SP3" --noUI --runscript="D:\TestScripts\Forum_Environment.py" I have tried the following just to open the test project: SET PROJECT=C:\TEST\Example.project start CODESYS.exe --profile="CODESYS V3.5 SP20 Patch 2" But I'm not sure how to specify this project to be open after py script is executed. The py script should first add required library to the project and then project should be open.

just now i have tried loading the achive file from today at work. using 3.5.20.4 same as at work. when i open the project it says " prject inspection, this project has been saved with a different version(codesys v3.5 sp20 patch 4).? one option in the above "project inspection" window just wants to download that same version again. the other option leads no where as it say the required add ons cant be resolved. just end up going around in circles.

Hello everyone. I have a problem: I installed new version of codesys IDE. When I try open project in this new version, I have many errors about Visu: rectalnge/button/frame/etc does not exist. How update properly project? 20+ pages of visu pages from 100+ frames and all visu elems looks like "Error image". It is not problem of SP20->SP21. Any update has problems from visu side.
