Hi:

My client has a TP Comfort 1200 use to display a log several PLC tags.

Currently, the HMI application is logging the tags using segmented circular log to a remote folder. However, the client complains that the logging stops intermittently, and the only way the restart logging is by rebooting the HMI. After the HMI is rebooting, the data during the intermission is not recorded.  

I was thinking that by logging the data to an SD card the data will be more reliably stored. However, I cannot use ArchiveLogFile function to move or copy the log file to a remote folder. I do not want to use trigger event logging method, as I am concern that the connection is not working during the archiving and data might be lost.

I am using TIA Portal V15.1 

Hello MrKankuamo,

Is not recommended to do the logging on a remote folder, because as you describe you can have communication problems that makes to lose information.

I recomend you to do the log in the local memory and later copy it to the remote folder with the event CopyLog.

To be able to exchange files, the shared folders of Windows are used, being the screen only client of these folders. I explain in a PC you must have a shared folder in Windows to which the screen can access. Once you have that folder with the "CopyLog" event you could copy any file from the screen to that path (https://support.industry.siemens.com/cs/es/en/view/109755202/103441923339).

To configure the shared folder with the panel I recommend you to check the following FAQs:

 Thank you Troubleshoot_er

How does CopyLog works with segmented circular logs? The functions copies all the segments if there is more than one locally? I assume you have to create two Data logs that are identical but one stored in the remote shared folder and one in the local SD card. 

I was considering using ArchiveLogFile with a circular log, triggering the function at regular periods shorter than the log would take to completely overwrite all data.
