Modular RTUs at a glance
With modular RTUs based on SIMATIC controllers, telecontrol applications can also benefit from the advantages of different controller families. The RTUs are connected to control centers via communications processors (CPs) or Telecontrol Interface Modules (TIMs). They are configured in the TIA Portal using SIMATIC STEP 7 Professional.
Highest level of performance for complex telecontrol applications
RTUs based on the SIMATIC S7-1500 Advanced Controller deliver convincing results and the highest levels of performance and flexibility. They can be connected to a telecontrol center via the TIM 1531 IRC Telecontrol Interface Module.
Telecontrol protocols supported:
- SINAUT ST7
- DNP3
- IEC 60870-5-104/101
The TIM 1531 IRC Telecontrol Interface Module can be used as both a node and the master station. RTUs based on SIMATIC S7-1500 are ideal for complex telecontrol applications like those used in widely dispersed sewage and wastewater treatment plants, district heating systems, power engineering, and traffic engineering.
Sample configuration
The RTUs are connected via public or private communication networks (Remote Networks) using an external industrial router like SCALANCE M. The router is connected to the TIM’s Ethernet interface. TIM 1531 IRC has three Industrial Ethernet interfaces and one serial interface for connecting a modem (like MD720). This allows it to provide a variety of redundant transmission paths (for example, Internet and mobile wireless) to higher-level stations. Even if the primary connection fails, the TIM can still transfer the data.
Powerful RTUs for comprehensive control tasks
RTUs based on the SIMATIC S7-400 Advanced Controller are especially suitable for complex process plants. They can be connected to a telecontrol center via the TIM 4R-IE or TIM 4R-IE DNP telecontrol interface module.
Telecontrol protocols supported:
- SINAUT ST7
- DNP3
- IEC 60870-5-104/101
The Telecontrol Interface Module can be used as both a node and a master station in order to structure the telecontrol applications. Redundant stations can also be implemented. RTUs based on SIMATIC S7-400 are ideal for the most complex telecontrol applications like those used in widely dispersed sewage and wastewater treatment plants, district heating systems, power engineering, and traffic engineering.
Cost-effective RTUs for applications with a low degree of automation
Modular Remote Terminal Units (RTUs) based on cost-effective SIMATIC S7-1200 controllers are particularly suitable for applications with a low degree of automation. They can be connected to a telecontrol center via a communications processor (CP).
Telecontrol protocols supported:
- TeleControl Basic
- SINAUT ST7
- DNP3
- IEC 60870-5-104/101
RTUs based on SIMATIC S7-1200 are ideal for small stations in telecontrol applications like those used in widely dispersed sewage and wastewater treatment plants, district heating systems, power engineering, and traffic engineering.

Compact design and impressive performance
RTUs based on the SIMATIC ET 200SP Distributed Controller deliver convincing results, thanks to their especially compact design and impressive performance. They can communicate with a telecontrol center through the CP 1542SP-1 IRC communications processor using a telecontrol protocol.
Telecontrol protocols supported:
- TeleControl Basic
- SINAUT ST7 (firmware version V2.0 and higher)
- DNP3
- IEC 60870-5-104/101
This means that telecontrol applications can now also benefit from the advantages of the SIMATIC ET 200SP system, including its extreme flexibility and user-friendliness. For example, RTUs based on SIMATIC ET 200SP are used in sewage and wastewater treatment plants and district heating systems and in oil and gas supply, power distribution, and traffic engineering.
Configuring RTUs with SIMATIC ET 200SP
The CP 1542SP-1 IRC communications processor supports a number of telecontrol protocols. It can be used to connect Remote Terminal Units based on SIMATIC ET 200SP to different control centers. In addition to the DNP3 and IEC 60870-5-104 telecontrol protocols, the CP also supports the Siemens SINAUT ST7 (firmware version V2.0 and higher) and TeleControl Basic telecontrol protocols. The telecontrol protocol can be easily defined during configuration.
