S7-300 with one TIM 4R-IE
With an S7-300 and one TIM 4R-IE, it is possible to set up an extremely efficient node
station. The following figure shows an example in which the control center is connected over
one of the two Ethernet ports of the TIM. The connections to the subsidiary stations are
established over the other three interfaces: here, over two classic WANs using suitable MDx
SINAUT modems and over an Ethernet-based WAN, in this case an FO cable connected via
a SCALANCE X switch.
In these configurations, the control center and stations can exchange data among
themselves over the TIM 4R-IE as well as with the CPU of the node station. The TIM 4R-IE
also supports direct communication between stations in the three underlying networks, in
other words both within a network and from one network to another.

Instead of the MDx SINAUT modem, other modems with an RS-232 or RS-485 interface can
also be used, for example wireless devices or the SINAUT GSM modem MD720-3.
The following figure shows a different node station variant in which the TIM 4R-IE has a
redundant connection both to the control center and to the subsidiary stations. A variant of
this configuration would be to have a redundant connection only to the control center and to
have single transmission paths to the stations. Which two ports are redundant can be freely
selected by the user.
