The SPPA
-
T3000 DCS consists of a ‘3
-
Tier’ architecture that is based on the server/client
networking structure. This architecture along with the use of Web technology, Industrial
Ethernet communications and a component
-
based software structure combine
to form a
state
-
of
-
the
-
art Distributed Control System that has been consistently tailored to the process
engineering needs of modern power

plants.

The 100Mbit Ethernet bus system (Application Bus and Automation Bus) provides
the communicati
on between the HMI, the Automation Units (Automation Servers)
and the Application Server who provides all necessary functions for plant
engineering, operation
-
monitoring, diagnostics and storing of process data. The
connection to the field devices is imple
mented via I/O modules which are installed
in I/O cabinets.

is the basic concept of the system
that embeds all available process
-
relevant data into every single component. This
component
-
embedded approach allows all

data to be intrinsically available for
operation, engineering

or
diagnostics.

H
omogenous system architecture simplifies the system structure, offers a Single
User Interface for all tasks and eliminates the need for the sub
-
systems and
elaborate interface
s fou
nd in classic control systems.
This improves capabilities for
tasks like DCS support and initiatives like plant optimization and process
modification.

The salient features and main advantages
of SPPA
-
T3000
are:



SIEMENS experience from power plant an
d power plant automation



Use of proven automation components from the SIMATIC family



Introduction of technologies such as Web interface, Gateway server etc.



100 M bits/s network system ensuring single fault tolerant redundant bus
system.



Use of remote I/O
concept using redundant field bus PROFIBUS
-
DP up to 12 M
bits/s



Functionality tailored and perfectly adapted to the needs of power plant
automation to give efficient, cost
-
effective and low
-
stress plant control.



Scalable DCS featuring high availability and

with automation components also
suited for open
-
loop controls and protection circuits with high safety and
reliability requirements.



Easy to expand by installing additional programmable logic controllers.



Open system architecture based on openness to the
office world via OPC
-

server



Service and support



Sequence of Events (SOE) functions capturing events at the rate of 10ms
accuracy for a limited number of max. 200 signals.



Fail Safe Protection system based TÜV certified fail s
afe processors, confirming
to Safety Integrated Level SIL3 norms of IEC 61508, DIN V19250 and NFPA
requirements.
