The TIM is available in three basic variants:
● TIM 3
TIM 3x without MPI port, only for installation as a CP in the S7-300 with only one WAN
port: either over the integrated modem or over the serial port for an external modem.
● TIM 4
TIM 4x with MPI port both for installation as a CP in an S7-300, can also be connected as
a stand-alone device over MPI to one or more S7-400 and S7-300 PLCs. The TIM 4 has
two WAN ports: one over the modem integrated in the TIM, the other over the serial port
for an external modem. The two WANs can be identical or different, for example
dedicated line plus telephone network.
● Ethernet TIMs
– TIM 3V-IE variants with two WAN attachments: An RS-232 port and an RJ-45 Ethernet
port, only for installation as a CP in S7-300. With the TIM 3V-IE, SINAUT
communication is either over the RS-232 or over the Ethernet port. The
TIM 3V-IE Advanced can use the RS-232 port at the same time as the Ethernet port.
– TIM 4R-IE with four WAN connections: Two RS-232 interfaces and two RJ-45 Ethernet
interfaces. Installation as a CP in an S7-300 or as standalone device in a separate
TIM rack. With the TIM 4R-IE, SINAUT communication is handled over the RS-232
and over the Ethernet interfaces simultaneously.
Topology
The topology describes the network structure. It specifies how a network (transmission
medium and connectable devices or computers) is interconnected. Possible structures are
linear (bus), star, ring, redundant ring and tree structure.

VPN
(Virtual Private Network)
The principle of a virtual private network is to use public networks such as the Internet to
transfer private data. The communications partners of the private network can exchange
data as if they were part of a LAN. Communication can be secured using various encryption
and authorization techniques.
WAN
(Wide Area Network)
Wide area networks are intended for language or data transmission over greater distances.
The concept of such networks is essentially decided by the services available.
The basic structure of a wide area network can be based on circuit switching or packet
switching. The circuit switching structure uses a hierarchical arrangement of switching
points. WANs can have a span of several thousand kilometers.
The following WANs can be used with SINAUT:
