Hi.

I have an setup were I have 2 motors and a UV light were I have added some hours counters so I can see how many hours each part has been running (Turned on) 

I have them displayed in the LOGO display, and on my page on LWE. 

My problem is, how can i store the values, so they will stay there after an power reboot ?

Im using a stopwatch were I have marked "Retentivity" and "Protection active" under properties. 

I have added those stopwatches to the WM mapping sheet, and displayed them on my homepage through "VD" block. 

Hours are counting, but after a power reboot they start from zero again. 

Is there a way of keep the value, after a reboot?

I hope to get some help. 

Best regards

Hi.

Thanks. 

I hope it is the right file I have uploaded.

For me it seems my counters are not starting at all after a power reboot. 

I hope you can see what im doing wrong, or what I miss.

Strange

So the setup is correct in the program.

Is there a global setting on my logo plc i need to activate?

But thanks for trying, and I’m somehow glad I made the programing correct.

Best regards
