Commissioning
Start downloading automatically when the operating unit is in operation
The operating unit can be switched automatically to Download mode from normal
operation as soon as downloading is started on the connected configuration
computer. This option is especially recommended for the test phase of a new
configuration because the transfer is performed without intervention in the
operating unit. A condition for this is that the following settings are defined in the
Configuration menu (Figure 3-2):
MPI connection:
Option MPI Transfer Enable activated
Option MPI Transfer Remote activated
Serial connection:
Option Serial Transfer Enable activated
Option Serial Transfer Remote activated
A detailed description of the possible settings in the Configuration menu is
provided on Page 3-5.
Note:
The bus parameters (e.g. MPI address, baud rate, etc.) are read out of the
configuration which has been loaded on the operating unit. Important: A new
project with new parameters must initially be loaded on the operating unit with the
old settings (on the configuration computer) because the old parameters apply
here.
