Hi all

I know this question has been askes many times. But it seems non of the solutions are able to fix this problem in my project.

This project is for a 'servant' which moves along with the worker on the production line. SO the main goal is to make the motor rotate left or right at different speeds. The speeds should be set on the HMI under the screen 'MOTOR DRIVER' (the two top IO-fields). The problem is. When the production stops and the devices are shut off, the values are lost and the techniciens should go to every 'servant' to set the values. Of course we don't want this. Does anyone have any idea how to fix this?

LOGO!Soft program and Tia-file is in the attachment.

Thanks in advance!

The second LOGO in my logosoft file was not supposed to be there :). 

I tried to implement the solution you gave me, yet when the LOGO loses power, the values are still 0. Did I implement it wrong? 

The Tia file appears to be too large. But it's just a screen with 3 io-fields containing the HMI-tags with the adresses VW 5, VW 7 and VW11.

Thanks!

Thanks a lot for the help!

The program you sent me still doesn't keep the values from dissapearing. When I cut the power of the logo and then get put the power back on, the values on the logo and on the HMI's io-fields are again 0.

Would you have any explanation for this?

I tried both with the program on the SD card and without the SD card. but both times it gets the values only after I fill them in on the io-fields...

Here's the tag list maybe this gives you more information?

I do have linear scaling on the tags of the analog values. Also the io-fields are set to mode: input/output.
