TIM 4R-IE with SIMATIC S7-400
The TIM 4R-IE is connected to a SIMATIC S7-400 over one of the Ethernet ports of the TIM.
The connection of the S7-400 is via the PROFINET of the CPU or via an Ethernet CP.
Figure 3-24
Instead of the MDx SINAUT modem, other modems with an RS-232 or RS-485 interface can
also be used, for example wireless devices or the MD720.
Note
Fault-tolerant SINAUT solutions with a CPU 414-4H or CPU 417-4H are not possible.
The maximum number of TIMs that can be connected to S7-400 depends on the connection
resources provided by the CPU. With an S7-400, one (1) connection resource is required per
TIM. However, the available work memory of the CPU must also be taken into account; the
more TIMs installed and stations connected, and the more objects processed per station, the
greater the memory demands of the telecontrol-specific user program on the central CPU.
This program is put together with blocks from the SINAUT TD7 software package
(TD7onCPU).
Example of configurations with the SINAUT ST7cc or ST7sc control center systems
With the SINAUT ST7cc or ST7sc control center system, the TIM 4R-IE is connected to the
Ethernet card of the control center computer over one of its Ethernet ports.
The following figure shows a configuration for a control center system SINAUT ST7cc or
ST7sc with a TIM 4R-IE connected via Industrial Ethernet.
