TM241 unexpected behavior

[kelvinviroja93]

Dear Team,

I am using a TM241 controller for my one of my applications, and I am getting some issues with it.
Here are the details of controller :
Software Version- Machine Expert 2.2.2
Controller Model Number- TM241CE40U
Controller Firmware- 5.02.11.24

The Problem :
I am not using any type of DI/DO/AI/AO or any control logic in this application, I have used the controller to read the Modbus-TCP data and send that data to another system over Modbus-TCP.

So Basically here controller works as Modbus-TCP Client and Server.

When we download the application and run the controller it works perfectly for some hours and after some hours the application on the controller is automatically getting delete.

When we show the error on the controller and try to log in the controller, it has no application in it.

Last Error code : system error (1)

We redownload the application and same thing happen again after 18 Hours, the application on the controller gets deleted.

Here I am attaching the PLC Backup & syslog folder for your reference.

also, please find attached snapshot of Task timing and Ethernet Port status when the controller is running perfectly.

Let me know if you need any other details for further investigation.
Note : Controller is now at site in Africa Continent. We have access over AnyDesk only.
