I do not know whether an HMI can store input values. This is why my proposal looks like this: AttachmentStoring_setpoint.zip (232 Downloads) |

Hi shauns, It is possible to store values with a small trick. You actually don’t store it in the HMI, but in the logo itself. You have to write it to a virtual DB. I’ll look for an overview of the adresses and will post it later this day. Just look at the range of the adresses and choose an unused one. As long as the Logo has its source power this will work, the HMI can be switched on/off without the loss of this data. Regards Rick EDIT: Attached PDF with adress range. I think it is quiet the same way as Ixo mentioned. But in this case there is no programming necesarry. Program in the HMI an IO-field and use a tag (e.g. VW50). As long as the Logo doesn't use it!
