Hey,

I'm trying to log a counter value every X seconds, but when I want to upload the data to the PC, I get the message "no data is found".

I've tested some other programs, and they have a working log. Don't know what's wrong with my program.

I've fixed the issue.

- Create a new diagram with an empty log block. Download it to the LOGO and test it. ==> Log .csv file is created. (it's empty, but there is one)

- Copy the whole network without the "culprite" log block to the new diagram.

- Download it to the LOGO and now it's working. 

I found this work around here on the forum. Seems to be a bug...  

It was you.

First transferred your uploaded program to my LOGO! 8.FS4.
Since exactly the same error occurred as with you:
No data log to upload to the LOGO! and no CSV file on the SD card.
Then I deleted the "Data Log" block in the LSC diagram, selected all objects in the diagram, copied them and inserted them into a new, empty LSC diagram.
After that i create the data log and transferred the new program in my LOGO!.
And lo and behold ... A data log will be created, it can be uploades from the LOGO!.
And also on the SD card a data log was created.

In attachement:
- the new program (you must control the settings, IP address etc.)
- the uploaded Data Log from the LOGO! (192.168.178.32_2019-10-24 18-51-39.csv)
- the Data from the SD Card (32_18.csv)
