Depending on how you start up the Control Win, you can find the files in:<br/>
C:\Users\<user name="">\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\<br/>
Or<br/>
C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\</unique></unique></user></p>
<p>Delete the files in this folder, download your project again and start the application.</p>
<p>PS, if you have an older version of CODESYS, the files are in:<br/>
C:\ProgramData\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms</unique></p></div>History of Alarms2026-01-05T15:46:06.679000Z2026-01-05T15:46:06.679000Ztobiassantoshttps://forge.codesys.com/u/tobiassantos/https://forge.codesys.comf5b13fbdd4cfe74c97c7a0a7b8105c5983594b04<div class="markdown_content"><p>I am running tests using the Windows runtime environment.</p>
<p>The alarm history is not being logged and displays the error: "Some kind of disk I/O error occurred. Check disk space" in the alarm table. Furthermore, it is not possible to export the alarms.</p>
<p>I have already tried to find a configuration field in Alarm storage and Alarm configuration to fix this problem, but I haven't found any related fields.</p></div>
