Data transfer from and to the TCU

The USB interface of the TCU that is currently active is always the one accessed,

i.e., has the operator focus. If the active TCU changes during a data transfer, the

data transfer remains active in the background.

If an operation (copy, delete, edit) is active on the drive at the time of the TCU

switchover, the display is retained until the action is finished (in the case of the

editor, when the editor is closed). The display is not updated until the operation is

Because the TCU is connected to the HMI via a network connection, the response

times depend on the particular network. In the event of execution from an external

source or an EXTCALL, the program may be aborted. However, this is an unlikely

scenario as the TCUs are operated in a separate network.
