Standalone Tim 4R-Ie With An S7-400 Or Pc - Siemens SINAUT ST7 System Manual

Figure 3-23
In this example, the CPU of station 3 (not shown in figure) on WAN 3 communicates with the
master station and one or more stations on WAN 1 over a TIM 3 or TIM 4 and the TIM 4R-IE.
Note
When selecting the CPU in the above node station configuration, the following applies:
If the stations connected to the TIM 3/4 (for example station 3) also need to exchange data
with the CPU in the node station, you must use a CPU with a partyline, see table above.
If the TIM 3/4 does not need to communicate with the CPU in the node station, you can
select any CPU.

Standalone TIM 4R-IE with an S7-400 or PC

Introduction
In standalone mode, in other words, without an S7-300-CPU, the TIM 4R-IE is ideally suited
as a SINAUT communications processor for an S7-400 or for the PC of the ST7cc or ST7sc
control center.
