4.28.6 Automatic Download Function
The Automatic Download option can be enabled by selecting the appropriate check
box under ‘System Parameters’, ‘General Parameters’ in the programming sys-
tem.
The user description that contains this function must initially be loaded into the
terminal via a forced download (user-mode switch S4 at the ON position). Every
download thereafter is automatically initiated by the PC wanting to load the S3 file
of the new application into the terminal. A download can be forced when the oper-
ating terminal is in full operation.
During this process, all
-
message data in the message memory
- all RAM-data sets that have not been backed-up
- all system parameters that have been edited during operation (values of the
system variable, interfaces, passwords, etc.) will be lost!

4.29 Simulation without the Controller
The terminal can be operated without a controller by setting the user-mode switch
S3 to ON. The user-mode switch S3 will automatically set the external data re-
lease. It is possible to simulate the entire operator guidance including help texts.
The variables are automatically assigned to a common variable address in the
terminal. This allows the Editors and their limits to be tested. The values are, how-
ever, not retained. There is no communication with the controller.
