System log
    System logs are a generic mechanism for exposing messages from 
FactoryTalk Optix Studio
 to monitor software execution flow and diagnose problems. The logs are issued both by FactoryTalk Optix Applications
 and FactoryTalk Optix Studio
. The location of 
FactoryTalk Optix Runtime
 logs depends on the client device operating system:
      - Linux devices:/persistent/log/Rockwell_Automation/FactoryTalk_Optix
- Windows devices:%localappdata%\Rockwell Automation\FactoryTalk Optix\Application\Log
During the 
FactoryTalk Optix Studio
 design phase, any log messages that occur appear in the bottom bar of FactoryTalk Optix Studio
 and are saved.When you run the source project by starting your 
FactoryTalk Optix Application
, you can monitor log events from both the local development computer and the client device on which the  FactoryTalk Optix Runtime
 application is deployed. The FactoryTalk Optix Runtime
 log events are displayed in the FactoryTalk Optix Studio
 user interface on a separate status tab with the name of the client device. These logs are also saved on the file system at these locations:
      - For projects started in a local emulation:%localappdata%\Rockwell Automation\FactoryTalk Optix\Emulator\Log\<Project name>
- For projects started on a client device:%localappdata%\Rockwell Automation\FactoryTalk Optix\Studio\LogDevice\<Devicename>
