The RTU560 is able to communicate with different hierarchical levels of a network control system,with subordinated RTUs or any other intelligent electronic devices (IEDs),or with the test and diagnostic system.

 

The software application tasks can be organized in such a way as to be distributed over different communication units (CMU boards).

This is possible due to an internal communication concept that keeps all CMU boards informed about the contents of the process data interface. There is one process and system database which is available in adapted copies for each CMU board.

The internal communication system ensures that all process data are consistent. The different CMU boards run the communication tasks for the connected serial links. This allows the type and number of different communication links running on one CMU board to be defined.System performance is defined by the configuration of the CMU boards.

The most important standard protocols supported by RTU560 for communication with the control system are:

• IEC 60870-5-101  • IEC 60870-5-104

• DNP 3.0 (also on ethernet)  • Modbus

• RP 570/71  • Indactic 23/ 33/ 35

• TG 800  • Sinaut 8FW  • Conitel 300

 

For communication with subordinated RTUs and IEDs such as protection relays,local control units,etc.,the following protocols,among others,are available:

• IEC 60870-5-101  • IEC 60870-5-102

• IEC 60870-5-103  • IEC 60870-5-104

• DNP 3.0  • SPA-Bus

• Modbus  • RP570/71

• Indactic 21

 

The connection of the respective communication lines can be carried out in several ways:

• Direct links with RS 232-C interfaces(local communication)

• Voice-frequency telegraphy over leased telecommunication lines,private lines with narrow bandwidth modems or power line carriers

• Radio links  • Dial-up modem

• Fiber-optic cables  • Digital communication networks
