Turbine Control

In addition to traditional signal-type I/O, SD Series provides for integrated turbine control

solutions via a series turbine control-specific modules and include:

• Hydraulic Servo Module (VP01)

• Turbine Protection Module (TP01)

• Turbine Auto Synchronization Module (AS01)

• Condition Monitoring Module (MCM800)

These unique modules make it possible to provide a fully integrated single-vendor solution

for all aspects of turbine automation. Symphony Plus turbine solutions are based on proven

technology that controls steam turbines, gas turbines and hydroelectric turbines in more than

15 different countries around the world, and have been tested, accepted, and used as part of their

standard offering by several major global turbine manufacturers. With step change response

times of less than 20 msec, the SD Series turbine offering delivers powerful governor control

system solutions.

Intelligent HART I/O

HART field devices are seamlessly integrated through a variety of HART analog input and

output modules. This provides access to a wide range of intelligent field devices including

transmitters and actuators from ABB and other vendors. Besides the 4-20 mA primary variable,

all secondary, tertiary and quaternary variables in a HART device can be accessed by Function Code

control applications in the SD Series controller.

Data can be calculated, used as part of a control strategy, or for display and alarm purposes at

the S+ Operations console.

The SD Series` HART capabilities allow users to take full advantage of their HART instrumentation

investments. Too often smart devices are under utilized because of the limitations of the I/O

system to accept the device’s information. 

With SD Series HART modules, incorporation of the secondary variables in control strategies can

reduce the overall number of field devices and I/O channels required. Visibility of HART diagnostic

data at the system level reduces maintenance costs through the proactive response to

degrading performance of field devices before a failure occurs.

SD Series HART I/O features include:

• Each channel’s secondary/tertiary/quaternary variables are available for use in control applications

• Update rate of secondary/tertiary/quaternary variables is less than one second (AI05 and AO05)

Field device management

HART and PROFIBUS devices are fully integrated with Symphony Plus, yielding benefits far beyond

reduced footprint and cable costs. The S+ Engineering tool suite supports configuration,

commissioning and maintenance of HART and PROFIBUS devices using device type manager

(DTM) technology. For field devices that have conventional device description files (GSD),

a basic PROFIBUS DTM is available to allow standardized configuration. HART devices

are integrated, configured and parameterized via standard HART protocol without the need

for additional tools by using a standard HART DTM. Individual DTMs can be accessed from the

engineering tool’s multiple data views, such as the system or location overview and others.

S+ Engineering includes automatic net calculation and loading of process items by using the device

specific channel configuration generated from the DTM.
