The engineering work is an important cost factor
that can be reduced by standardizing the process
object model and ensuring that it supports state of-the-art engineering tools.The engineering tool
of the RTU must be able to perform the task of a
single,stand-alone RTU,as well as be able to be
integrated into an overall data engineering con cept for a network control system.
In addition to the basic functions,(i.e.data acqui sition and control) modern telecontrol systems are
required to provide a higher degree of functiona lity within the stations e.g.:
• High functional scope for telecontrol application
functions
• Execute control and closed-loop applications
using PLC capabilities
• Archive features to provide process data availa bility over longer periods for recovering or
de coupling,e.g.the storing of disturbance files re corded by protection relays in an archive and
analyzing them later,after transferring them to
an Office PC
• Communication with
multiple Network
Control Centers
(NCC).of process data
filtering according to
the demands of the
NCC.Possible with dif ferent telecontrol pro tocols for each NCC
• Extended diagnosis
functionality of the
RTU equipment to
reduce the costs for
problem analysis and maintenance by accessing
the information via Internet or Intranet options.
This should be possible independent of the di rectly connected telecontrol links
• Interfacing various types of IEDs,such as digital
protection relays or new transducers via field bus interfaces,etc
• Flexibility and space for future demands to ex tend the RTU for additional installed primary
process units and/or higher demands in terms of
control
The architecture of a telecontrol system must be
designed in such a way that it,thanks to its modu larity and flexibility,can be adapted to the con ditions and sizes of the different stations.It should
also be open for later extensions of any type.

ABB´s solution to different application require ments is the Remote Terminal Unit system RTU560.
A key feature of the RTU560 concept is the exten ded possibility to integrate the various communi cation
demands in a highly flexible and cost-opti mized way.The capability of RTUs has increased
significantly over the last few years.This has provi ded the opportunity to use remote terminal units
for different applications.The RTU560 uses the
same components to provide specific functions for
the different applications.Since all applications are
served out of the same product family a future up grade to a different application is always possible.
This goes in line with the ABB strategy to reuse
I/O modules of ABB RTUs 200/232 for upgrading
to RTU560.
The various functional requirements can be
grouped to the following three applications:
• Remote Control
• Communication Gateway
• Station Automation
