Hi, is it possible to keep the value (OT) 
in the work hours count after new doenload? 
Thank you

IF you want to monitor run hour you can do it. i hope this helpful.

@Rizlan. I think he want to keep the run hour hour rrtentive after download changes. 

I think therr was a workaround an expert named ixo posted sometime before. I am not accessible to Logo software now,but I would recommend doing a search in this LOGO conference with the term retentive and for sure you will get many example.

Thanks,

Jay

I imagined that it was not possible to do it, 
unfortunately the manual speaks clearly. 
It's a pity, because after a change the 
machine's working hours are lost. 

How can you manually reset the hours counter? Thank you

Hi,

if you DL a new or modified program to LOGO! and in LOGO! there is a programm uses the OHC, then during DL you get a warning.

If you want to keep the counted hours, then you need to read out the value from LOGO! and use this value in the new program as "Start time for OT" Value for the OHC.

Check my pictures.

Hope this helps
