3.4 Installation of the TIM 4 as CP in an S7-300
Both can receive the same data or data specifically intended for one or the other. The
transfer of commands, setpoints, parameters etc. to the stations in the telecontrol network is
possible from both ST7cc / ST7sc and from the S7-400.
The next figure shows a similar configuration. Here, a redundant SINAUT ST7cc or ST7sc
control center system is connected over one of the Ethernet ports.

Installation of the TIM 4 as CP in an S7-300
Introduction
This section explains the installation of the various TIM 4 modules in an S7-300.
A SINAUT program is required on the CPU for data exchange between the TIM and the CPU
installed in the rack. This is created for the CPU with blocks from the SINAUT TD7 library
(TD7onCPU). When selecting one the CPUs listed below that can all be used in principle
with a TIM 4, make sure that the work memory of the CPU is large enough to accommodate
the TD7onCPU program. The size of the program depends on the amount of data to be
transmitted. At least 20 Kbytes are required.
The TIM 4 can be used in an S7-300 as the communications processor (CP) along with one
of the S7-300 CPUs listed below.
