Hi everyone, I'm developing an application with a logo 
and a KTP-400 and I'm not able to create retentive 
variables every time I turn the panel off and the values ​​
go back to zero, someone could help with this

------------------------------------------------------------------------------------------
Split from linking logo function keys with ktp 400 basic panel.

Hello,

Perhaps you can explain, which variable you are using in Panel?

Do you switch off power from panel only? Or also switch off LOGO?

Best regards,

Wizard
