13.2 Recommissioning
When recommissioning, the configuration/firmware already loaded in the
Touch Panel is replaced by another. Downloading can be performed by means
of
S serial download or
S MPI download (for SIMATIC S7).
In the case of a serial downloading operation, the configuration/firmware is
transferred from the PC/PG to the Touch Panel via an RS232/TTY connection.
Begin by connecting the IF2 interface (RS232/TTY) on the Touch Panel to the
PU or PC using a suitable standard cable.
There are two ways of setting the Touch Panel to Download mode:
S In routine operation
The method of changing the operating mode of the Touch Panel online is
described in Section 11.1.
S In the startup phase of the Touch Panel
In the startup phase of the Touch Panel, the menu illustrated in figure 13-2
or figure 13-3, as appropriate, appears briefly in the initialization phase.
Touch the SERIAL DOWNLOAD button to set the Touch Panel to Down-
load mode before power up.
Providing the download operation to the Touch Panel has not started, you
can exit the Download mode by touching the BOOT CONFIGURATION
button to continue the boot operation.
Following a successful download operation, the Touch Panel powers up
with the new configuration and/or firmware and displays the start screen of
the configuration that has just been loaded.
