3.1 Installing the TIM 3V-IE variants in an S7-300
ST7cc / ST7sc with the TIM 3V-IE Advanced
A TIM 3V-IE Advanced can be used as a master TIM for the PC of the ST7cc or ST7sc
control center. In this case, the TIM 3V-IE Advanced requires an S7-300 CPU because it
cannot work without a CPU.
In the two cases illustrated below, the maximum number of TIMs in the rack is not limited by
the connection resources of the CPU because they are not required. You should not insert
more than 8 TIMs. Less TIMs per CPU are preferable to achieve better availability. The
greatest availability is achieved when there is only one (1) TIM in the rack connected to the
CPU over the backplane bus.
There are two ways of connecting the CPU/TIM module combination to the PC as illustrated
by the following two configurations.
Connection to ST7cc / ST7sc over MPI
The following figure shows a configuration in which the TIM is connected to the PC over the
MPI interface of its CPU. This is possible only when one of the CPU modules listed in the
section "Installation of the TIM 4 as CP in an S7-300 (Page 108)" is used in the S7-300 rack.
Only then can the TIM be addressed as a node under its own MPI address on the MPI bus.
This allows the PC and TIM to exchange data directly. No SINAUT software is necessary on
the CPU.
With this configuration, the TIM 3V-IE Advanced provides the control center with two
connections to a WAN:
● over the RS-232 port to a classic WAN
● Over the RJ-45 interface to an IP-based WAN
Figure 3-6
With this configuration. further TIM 3V-IE Advanced modules could be inserted in the S7-300
rack and all connected to the PC over the MPI port of the CPU. Each TIM provides the PC
with two further connections to the WAN. In this case, the maximum number of TIM modules
is not restricted by the connection resources of the CPU because they are not required. The
