Connecting the Configuration Computer
In order to download the configuration, a connection between the configuration
computer (PU or PC) and OP must be established. There are two connection
options available for this:
the serial connection of a configuration computer to the OP interface IF2
(serial downloading),
the connection of a configuration computer to the OP interface IF1B (MPI
downloading). In this case, the configuration computer and OP are con-
nected to the MPI network. A condition for this is that a configuration
already exists on the OP.
Both connections serve for downloading the firmware and configuration data
(Chapter 14.2). Standard cables are available for the connections shown (refer
to the ST80.1 catalog).
