6.2  Operating modes 
Operating modes 
The HMI device may be in the following operating modes:  
●  Offline 
●  Online 
●  Transfer 
"Offline mode" and "Online mode" can be set on both the configuring PC and the HMI 
device. To set these modes on the HMI device, use a corresponding operating element of 
the project.  
Changing the operating mode  
The configuration engineer must have configured an appropriate operating element 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" operating 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" operating mode 
In this mode, the HMI device and PLC communicate. You can operate the plant on the HMI 
device according to your system configuration. 
"Transfer" mode 
In this mode, you can transfer a project from the configuring PC to the HMI device or backup 
and restore HMI device data, for example. 
The following options are available for setting "Transfer" mode on the HMI device:  
●  When the HMI device starts up 
Start "Transfer" mode manually in the HMI device Loader. 
●  During ongoing operation 
Start the "Transfer" mode manually within the project using an operating element. The 
HMI device toggles to "Transfer" mode when automatic mode is set and a transfer is 
initiated on the configuring PC.
