Transferring the project to the HMI device
The following can be performed to transfer a project to an HMI device:
●
Transfer the project from the configuration computer
●
Restore the project from a PC using ProSave
In this case, an archived project is transferred from a PC to the HMI device. The
engineering software need not be installed on this PC.
These procedures can be are available for commissioning and recommissioning a project.
Commissioning and recommissioning
●
When the HMI device is commissioned there is no project at first.
The HMI device is also in this state after the operating system has been updated.
●
When recommissioning, any project on the HMI device is replaced.

Setting the operating mode
Operating modes
Operating modes of the HMI device:
●
Offline
●
Online
●
Transfer
"Offline mode" and "Online mode" can be set on the configuration computer and on the HMI
device. To set these modes on the HMI device, use a corresponding operator control object
of the project.
Changing the operating mode
The configuration engineer must have configured an appropriate operator control object to
allow a change of the operating mode on the HMI device during ongoing operation.
Further information on this may be available in your plant documentation.
"Offline" mode
In this mode, there is no communication between the HMI device and PLC. Although the
HMI device can be operated, it cannot exchange data with the PLC.
"Online" mode
In this mode, the HMI device and PLC communicate. You can operate the plant on the HMI
device according to your system configuration.
