5.31 Downloading a Project
The Download function describes how you can load a new project into
the Flash memory of the operating device. To do this, you must con-
nect the operating device with the PC and set it to the download oper-
ating mode.
To do this:
• In a mask, enter the value 1 in the system variable IntEraseEprom
OR
• Switch off the supply voltage, set the user mode switch S4 to ON,
switch on the device again, and - after the system message appears
- switch the user mode switch S4 to OFF again under operating volt-
age.
If, instead of a Flash memory, the operating device contains a UV-eras-
able EPROM, the system recognizes this and prevents a deletion or
programming process.
The following error message is displayed:
Fig. 5-77: Error message FLASH MEMORY FAILURE
This error message indicates that a write process was not completed
successfully.
During programming, we recommend that you activate the automatic
download function. By starting the download on the PC, you automati-
cally set the operating device to the download operating mode.
5.31.1 Automatic Download Function
You activate the automatic download function in the project’s system
parameters. Before you can use the function, you must (one time) load
the project conventionally to the operating device using the automatic
download function.
You can force each subsequent download when the operating device
is running, by starting the download on the PC.
If you do this, the following data is lost in the operating device:
• Message data from the message memory
• All RAM data sets that were not saved
• All system parameters that were changed online (values of system
variables, interfaces, passwords).
