6.1 SIMATIC RTU3000C
Overview
TeleControl means the monitoring and control of widely distributed process stations (RTUs /
Remote Terminal Units) through one or more central control systems. The communication
takes place via public networks, for example mobile wireless / Internet, or private networks
with special transmission protocols. Both standard protocols (DNP3, IEC 60870) as well as
Siemens protocols (SINAUT ST7, TeleControl Basic) are supported.
A distinction is made between compact and modular RTUs. This section describes the
compact RTU series SIMATIC RTU3000C. You can find the the modular RTUs on the basis
of SIMATIC S7-1200, ET 200SP, S7-1500 and S7-300/400 in section "Communications
processors for SIMATIC S7 (Page 309)".

The compact remote control units RTU (Remote Terminal Unit) offer secure monitoring and
controlling of outlying stations that are located far from each other and from the control
center and are not connected to a power supply network. The self-sufficient Low-Power
RTUs are suitable in particular for usage in rugged environments of -40 to +70 °C, also
without local power supply or communication infrastructure. An RTU can be supplied with the
