But when i open the screen where the buttons for that logo (and the other 2 logos) are the notificiations stop. does anyone know what to do?

(See online help: Performance Comfort panels) Best regards, Wizard In this case it would be a solution to transfer the display data over master/master-connection between the Logo controllers, if there is place for data exchange.

For master/slave makes the slave LOGO! the master LOGO! their I/Os are available and has no program. For this, the slave LOGO! must set to slave mode. For master/master, every LOGO! hastheir own program and only exchange the data with each other. In your LOGO! project, the LOGO!s "LV7 Shop" and "Logo laagspanningsruimte" communicate with the master/master procedure. Can you make a screenshot of the connections in the TIA project so that we can see with which LOGO!s the HMI communicates?

You can not use more than 8 connections. If you want to display data from LOGO!s for which you have no connection to the HMI, then you first have to transfer this data into a LOGO! which has a connection to the HMI. That's what the User Scorp means.....
