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.
The TIM 3 series includes the older modules TIM 3V, TIM 32, TIM 33 and TIM 34, see
release 05/2007 of the manual
(http://support.automation.siemens.com/WW/view/en/22548697).
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.
Unconditional spontaneous message
In the dial-up network, you can specify whether or not a change causes an "conditional
spontaneous" or "unconditional spontaneous" transmission for each individual message.
Unconditional spontaneous messages cause the connection to be established immediately.
Even with pay-by-volume/time transmission in a GPRS network, you can use the message
prioritization "unconditional spontaneous"; in other words, in contrast to a "conditional
spontaneous" message, a message is transmitted immediately.
