S7-300 with modem connection for access to the WAN
To implement classic WAN access for an S7-300, you can use a TIM 3V-IE DNP3 or
TIM 4R-IE DNP3. The following figure shows such a configuration.

MDx modem
Other modems with an RS-232 interface can be used, for example wireless devices.

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
● 3G/UMTS router SCALANCE M875 for data transfer via mobile wireless with GPRS
● ADSL router SCALANCE M812 for data transfer via the Internet
● Backbone transmission systems such as OTN, PCM30
Two examples are illustrated below.
