13.1 Initial Startup
The firmware and configuration must be downloaded to the Touch Panel when
it is started up for the first time.
All the units in the SIMATIC HMI family are equipped with reverse battery
backup. The reverse battery backup is not effective if a connection to the con-
figuration computer already exists to download the generated project.
For this reason, the following procedure is absolutely essential for download-
ing and commissioning the unit:
Step Action
1 Switch on the Touch Panel’s power supply. Since a configuration
has yet to be loaded at this stage (and no PCMCIA card has been
inserted in another unit, refer to chapter 9.3, Load configuration in
another unit), the Touch Panel automatically enters Download
mode, displaying the message
”READY FOR SERIAL TRANSFER”
and waits for data to be downloaded from the PU or PC
(see figure 13-3).
The Touch Panel cannot be operated in Download mode.
2 Connect the IF2 interface (RS232/TTY) on the Touch Panel to the
PU or PC by means of a suitable standard cable.
3 Start the download operation on the PC or PU to the TP27, TP37.
The Touch Panel checks the connection to the PC or PU. If the con-
nection is not available, or if it is not functioning correctly, the
Touch Panel issues the corresponding error message.
If the connection is in order, downloading of the configuration
commences. The Touch Panel’s firmware is downloaded automati-
cally.
Following successful downloading, the Touch Panel restarts and
displays the start screen of the configuration that has just been
loaded.
Note
Please refer to theProTool for information on which settings are required for
the downloading operation in User’s Guide ProTool Configuring Graphic
