ABB NAIO-03 64212389 Inverter I/O Expansion Unit
For communication gateways,minimal engineering
and implementation of standard and non standard
protocols is crucial. The RTU560 with its open
architecture and user friendly tools satisfies these
requirements.

for disturbance data and load profiles
• Retrofit with digital bay controllers possible
step by step
Benefits:
• Reduction of complex front-end systems
• Higher availability of WAN networks
• Reduced costs for data engineering
• Redundancy concept adaptable to
availability requirements
Station Automation
The station automation application consists of
interfaces to a mixture of protection and control
equipment as well as metering devices and other
automation products.The Human Machine Interface integrated into the RTU560 allows a basic local
control and monitoring.
Transmission of disturbance records and load profiles by using the communication network of the
RTU560 are also available functions

The software and hardware concept is based on
modularity. 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 perfor mance is defined by the configuration of the CMU
boards.
