Page 15: Application And Functions
Application and functions Application and use of the RTU Applications The RTU is intended for monitoring and controlling small outlying stations without a connection to a power supply network. In telecontrol networks, the RTU is used to connect the outlying stations to the master station via mobile wireless or via the LAN interface of the RTU and an optional external router.
Page 16 Application and functions 1.1 Application and use of the RTU ● Communication with the control room If a communications partner is available in the master station, the RTU can send process data to the control room. The data is transferred either via the mobile wireless service GPRS or UMTS or via LAN (optionally with an external router).
Page 17: Configuration Examples
Application and functions 1.2 Configuration examples Configuration examples Below, you will find configuration examples for applications of the RTU. You will find references to the configuration of individual communications functions in the section Communications services (Page 25). You will find a diagram of the configuration of the configuration PC that accesses the WBM of the RTU using HTTP and OpenVPN in the section Establishing a connection to the WBM of the RTU (Page 101).
Page 18 Application and functions 1.2 Configuration examples Telecontrol with the "TeleControl Basic" protocol In the following example the RTU uses the "TeleControl Basic" protocol and communicates via the mobile wireless network and the Internet with the teleconrol server (TCSB) in the master station.

Page 26 ● TeleControl Basic This is a proprietary protocol of Siemens for telecontrol applications. The IP-based communications protocol is used to connect the RTU to the application TCSB. TCSB is installed on a PC in the master station, the telecontrol server. For the version, see section Scope of delivery, accessories, requirements (Page 39).
Page 27 Application and functions 1.6 Communications services ● DNP3 The RTU functions as a DNP3 station (Outstation). Communication is based on the DNP3 SPECIFICATION Version 2.x (2007/2009). The RTU is certified for the DNP3 conformity levels Level 1 and 2, but also supports higher conformity levels.
Page 28 Firmware for the protocols DNP3, IEC and ST7 To use these telecontrol protocols, you need to load the corresponding firmware variant on the RTU. You can obtain the suitable firmware file free of charge from Siemens Industry Online Support: ● Link: (http://www.automation.siemens.com/aspa_app/) Here, you will find a contact.
