Direct communication over TIM 4R-IE and other TIM modules
As described above, with a TIM 4R-IE, direct communication is possible between all stations
on all networks connected to the TIM. If there are other TIM modules on Ethernet or on the
MPI bus in addition to the TIM 4R-IE, direct communication can also be extended to the
networks of the other TIMs.
The first example shows the path of direct communication between stations connected to a
standalone TIM 4R-IE and a TIM 3V-IE. The two TIMs are interconnected over Ethernet.

(direct communication paths are shown as dashed lines)
The second example shows the path of direct communication between stations connected to
a standalone TIM 4 and a TIM 4R-IE. The two TIMs are interconnected over MPI. The
TIM 4R-IE is installed in an S7-300 so that it can communicate with the standalone TIM 4
over the MPI interface of the CPU. Within the S7-300, the direct communication path is via
the backplane bus.
