S7-300 with access to IP-based WAN
To implement IP-based WAN access for an S7-300, you can use either a TIM 3V-IE or a
TIM 3V-IE Advanced.
Figure 3-12
A module is required on the Ethernet interface (RJ-45) of the TIM to link the TIM to an IP-
based WAN. The following are, for example, possible:
● SCALANCE X switches for twisted-pair or FO cable
● SCALANCE W wireless devices for data transmission over IWLAN
● Other wireless devices optimized for Ethernet
● GSM router SCALANCE M874 / MD741-1 for data transfer via mobile phone with GPRS
● MODEM MD720 for simple Internet communication with an MSC tunnel (see Vvolume 2
of this manual)
● DSL router
● Backbone transmission systems such as OTN, PCM30
Two examples are illustrated below.
