Data management

The configuration data of the ETL600 can reside in several locations:
1. In the RAM of a PC.
2. As a data file on the hard disc of a PC or on other media.
3. In the volatile RAM of the modules P4LT, O4LE, G4AI of the
ETL600.
4. In the non-volatile flash EPROM of the modules P4LT, O4LE,
G4AI of the ETL600.
In addition to the above, a printout of the configuration data can also
be taken for storage on paper. The configuration file can be generated
off line and downloaded later into the equipment. The following figure
shows the data management in pictorial form.

The procedures for transferring data between the locations all have
distinct names. As shown in the figure, there is no direct possibility of
data transfer from equipment EPROM to file: The operations 'Reset',
'Upload' and 'Save' have to be executed in sequence. To transfer data
from file to EPROM, the operations Open, Download, Store have to be
called.
Due to safety reasons, the HMI600 program treats the download
procedure as a temporary operation: After a predefined timeout to be
