Unintentional transfer mode
If the HMI is accidentally switched to Transfer mode, unintentional actions can be
triggered in the plant.
Ensure that the configuration PC does not inadvertently switch the HMI device to
transfer mode while the project is in runtime.
3. Select the required protocol for "Channel 2" in the selection box.
Serial transfer mode via channel 2
The bus parameters, for example address of the HMI device, are read out of the project
that is currently running on the HMI device.
You can change the settings for the transfer via channel 2.
The following steps are required:
• Close the project.
• Change the settings on the HMI device.
• Then return to "Transfer" mode.
The next time the project is started on the HMI device, the settings will be overwritten by
the values from the project.
