Figure 3-12 Direct communication over a TIM 4 (standalone), MPI and a TIM 4R-IE, installed in an
S7-300; communication within the S7-300 over the backplane bus
(direct communication paths are shown as dashed lines)
A further example shows the path of direct communication between stations connected to a
TIM 4R-IE and a TIM 4 or TIM 3. The two TIMs are installed in an S7-300 and
interconnected over the backplane bus. Within the S7-300, the direct communication path is
via the backplane bus. In this example, this also applies to the data exchanged with the
master station over the TIM 3/4 (see figure below).
