Telecontrol substation using the example of an RTU based on the SIMATIC S7-400 Advanced Controller
High-performance RTUs for extensive control tasks
Modular remote terminal units based on SIMATIC S7-400 are particularly suitable for complex process plants. TIM communications modules (Telecontrol Interface Modules) are used for the connection to the control center. As independent modules – connected to the SIMATIC CPU via the Industrial Ethernet interface – they enable the reliable transmission of control and process data.
The following TIM modules are available for the S7-400:
- TIM 4R-IE supports the telecontrol protocol SINAUT ST7
- TIM 4R-IE DNP3 supports the telecontrol protocol DNP3 (IEEE 1815)
- TIM 1531 IRC for the telecontrol protocols SINAUT ST7, IEC 60870-5-104/101 and DNP3
The TIM modules mentioned can also be used to implement a modular remote terminal unit based on SIMATIC S7-300.
TIM modules TIM 3V-IE, TIM 3V-IE DNP3 and TIM 3V-IE Advanced are also available for the SIMATIC S7-300. These as well as the TIM 4 modules (S7-300 module format) can be used directly in an S7-300 station and are directly connected to the S7-300 CPU via the backplane bus.

Modular and flexible
The Advanced Controllers SIMATIC S7-400 and S7-300 offer an extensive range of varying CPU types and a large number of I/O and technology modules.
-
Various Telecontrol protocols
Connection to all types of Telecontrol control centers with IEC 60870-5-104/101, DNP3 or SINAUT ST7.
-
Secure communication
Secured data traffic between the Telecontrol control center and the process stations in the field (RTUs) using encryption algorithms.
-
High availability
Path redundancy offers high availability even when the primary connection fails. Through support of the S7-400H CPUs, redundant substations can also be realized and connected to the Telecontrol control center.
-
Simple configuration
Standard engineering with TIA Portal STEP 7 enables easy and fast programming, networking and commissioning.
Configuration examples
The figure below shows a simple S7-300 station equipped with a TIM 3V-IE. The S7-300 can be connected via the RS232 interface of the TIM to a conventional WAN (e.g. dedicated line or dial-up network), via the RJ45 interface to an IP-based network, e.g. LTE mobile network.

S7-300 with TIM 3V-IE
In the case of an S7-400, both a TIM 4 and a TIM 1531-IRC can be used for data communication. In both cases, the TIM is used as a stand-alone device.
G_IK10_XX_30209
S7-400 with TIM 4R-IE connected via Industrial Ethernet
In the case of the TIM 4R, two conventional WANs can be connected by means of the two combined RS232/RS485 interfaces. TIM 4R-IE has an additional connection for an IP-based network.
