7.2 Transfer
TP 270, OP 270, MP 270B (WinCC flexible)
7-10 Operating Instructions, Edition 03/2004, 6AV6691-1DD01-0AB0
Procedure
Proceed as follows:
1. Set the HMI device to "online"
2. Test all the items in the loaded project for which communication with the PLC is
necessary:
– Alarms
– Alarm logging
– Screen selection by PLC through PLC job
– Print functions
7.2.5 Uploading project
Introduction
During transfer, generally only the run-capable configuration (*.fwx) is transferred to the HMI
device. If the original project file is to be used for further development of the configuration or
for fault analysis, it must remain on the configuration computer.
The project and associated source file (*) can be stored on the HMI device. It can be
retrieved (transferred back) if necessary.
After uploading a project, it can be analyzed and modified. This is of particular importance if
• the original configuration computer cannot be accessed, or
• the project source file is no longer available.
Requirements
The following conditions must be fulfilled in order to retrieve a project:
• The HMI device is connected to a configuration computer.
• The associated source file is stored on the HMI device.
• The "Enable Upload" option must be selected in order for the project file to be transferred
from the configuration computer to the HMI device.
This option can be activated in WinCC flexible in "Project > Transfer > Transfer Settings".
• A memory card is inserted in the HMI device.
Downloading and uploading
In the case of transfer, including transfer of the source file, the project file is transferred to
the HMI device.
Following uploading onto the configuration computer, the *.pdz file is compressed by the
WinCC flexible configuration software. The project is then available in HMI format on the
configuration computer and can be edited.
