RSView32- How to log the derivative tags

[jpepower]

Please tell me how to log the derivative tags data in the Rsview32 Run program. I have created the derivative tags on the Editor and in the model tags, i have choosen the ordinary tags and derivative tags to log ( data enregister )but the derivative tags data are always 0000. I know this is not true. some thing wrong with the log processus with derivative tags. If some one has done this, please help me.
Thanks

Hello;
First you have to start your derived tag file. I believe this is with the derivedOn filename command.

Yes, in the Start-up menu, I click on the derivative. I did not use the filename command. I think it is corect also.
Please advise.
thanks
