6.2 Synchronization As soon as the REX 200/250 has logged into your account in the portal, you can transfer subsequent changes at any time with “Synchronize”. Where there is an existing myREX24-V2 portal connection, the REX 200/250 checks cyclically whether there is a new configuration available for its serial number and then loads it automatically. -
Page 17: Connection To The Machine Network
The synchronization function is confirmed through the following dialog: In this menu, you can select optional user-defined settings, such as the sending of information/confirmation mails.
