ABB NBIO-21CU 3BSE017427R1 Analog IO unit
The RTU560 is able to communicate with differenthierarchical levels of a network control system,
with subordinated RTUs or any other intelligent
electronic devices (IEDs),or with the test and dia gnostic system.
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 subordina ted RTUs and IEDs such as protection
relays,local control units,etc.,the fol lowing 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 tele communication lines,private lines with narrow
bandwidth modems or power line carriers
• Radio links
• Dial-up modem
• Fiber-optic cables
• Digital communication networks
