Update from the PG/PC via PROFIBUS-DP (Direct)
The PG/PC with the update files is connected directly to the PROFIBUS interface
of the IM 153-2 (see Figure 7-3).
Note
If no STEP 7 project containing the IM 153-2 concerned is available, the update
can also be performed using the online view (Accessible Nodes) in STEP 7.

Update from the PG/PC via PROFIBUS-DP and CPU
The PG/PC with the update files is connected to the MPI interface of the CPU. The
IM 153-2 is connected to the 2nd interface of the CPU via PROFIBUS-DP (see
Figure 7-4). The IM 153-2 must be integrated in the STEP 7 project on the CPU.
