MTP1000 reporting csv file to USB failure?

Hi all,

We have an issue with an MTP1000 panel running 18.0.0.3 with csv file write failure to the USB stick?

> Logs set for OnChange + Trigger on rising edge based on a log enable button  by the user.

> Reporting system was working fine for the first few days and stopped writing any files to the USB       now.

> Only new addition is the creation of a new network drive path that we are trying to implement as we suspect the siemens panel has limitations with the read/write cycles to the USB stick.

> 11 tags are being logged 24x7. These tags have been set for 30 sec acquisition cycle from PLC as siemens does not allow Cyclic + Trigger.

> USB size is 256 GB and log are set for 10GB for logs and 20GB for audit.

Script is defined as below,

So once the write is complete the button turns green if write failed it should turn red. 

The concept worked fine for the first few days and then stopped working all together.

any pointers/insights would be helpful.
