ABB Symphony Plus SD Series HPC800 controller

batch and advanced control. In addition to standard function

blocks, the HPC800 supports C programming, batch, and

user defined function codes.

HPC800 controller features include:

− Simultaneous support for SD Series I/O, Harmony Rack

I/O, and S800 I/O subsystems

− Execution of closed loop control of more than 5,000 I/O

in less than 250 msec.

− Downloadable firmware

− Extended user configuration memory (NVRAM) and

runtime memory (RAM)

− Support for 30,000 function blocks

− Flexible and online configuration capability

− Support for up to 8 segment tasks, each segment

supporting execution cycle time down to 1 msec

− Dedicated redundant peer-to-peer controller communication

bus supports update rates less than 100 msec

High reliability and availability

The HPC800 is designed to provide maximum reliability

and availability. With a redundant design at all levels - CPU,

power, internal bus, I/O networks, communication ports and

plant network - HPC800 controller subsystems provide the

highest level of availability. Compliance with international

standards assures the highest level of reliability and quality

needed to meet the most rigorous specifications and

requirements from around the world. Together, they give

users the benefi t of fast, accurate, uninterrupted control of

their process production, resulting in greater production

effi ciency, increased availability and lower maintenance costs.

Ease of use

HPC800 utilizes a DIN-rail form factor, standard 24 VDC

power inputs, and a standard Ethernet network to make

installation simple and flexible. This reduces the limits

on cabinet space, size or layout, and provides a broader

selection of commercial power supplies and network

peripherals, thus lowering both installation and maintenance

costs.

Peer-to-peer controller communications

HPC800’s dedicated bus (CW800) for peer-to-peer controller

communications can achieve update rates of less than

100 msec. It is essential for fast and accurate control,

coordinating between several process segments (ie, between

boiler and turbine), and for when a process point is used

in several subsystems without adding a field transmitter or

cable. The CW800 peer-to-peer communication bus is fully

redundant.

Soft controller reduces commissioning times

For new plant, upgrade, or expansion projects, SD Series

soft controllers can dramatically reduce commissioning and

start-up time and costs by permitting thorough testing and

pre-tuning of control loops prior to its implementation in the

field. The SD Series soft controller uses the same control logic

(ie, function block configuration) as the physical SD Series

controllers. Coupled with virtual communication devices, the

entire SD Series control-based system can be implemented

within one or more PCs which allow for testing results made

in the virtual environment to be directly transferable to the

operating system environment.

Comprehensive I/O support

The HPC800 provides simultaneous support for SD Series

I/O, Harmony Rack I/O and S800 I/O subsystems, and is

capable of providing closed loop control for 5,000 I/O points

in less than 250 msec. This provides great flexibility and a

wide variety of input/output and signal condition capabilities,

which in combination form the optimal automation solution.

Using standard function codes, the S+ Engineering Composer

tool is used to configure and maintain all HPC800 I/O

modules and channels.

Through a redundant I/O network, HN800, each HPC800

controller can communicate with up to 64 SD Series

I/O modules, SD Series PDP800 PROFIBUS modules, or

Harmony Rack RIO22 modules. Each PDP800 can drive

more than 1,500 S800 I/O modules over PROFIBUS DP V2,

while each RIO22 module can drive 64 Harmony Rack I/O

modules. All HPC800 I/O can be configured as either local I/O

or remote I/O or mixed. Remote I/O is communicated via a

fiber optic extension. Sequence of events (SOE) with 1 msec

timestamp resolution is available across the entire system.

In addition to traditional signal-type I/O, the HPC800 provides

for integrated turbine control via a series of turbine controlspecifi

c modules. These are available in either Harmony Rack

form or Symphony Plus DIN-rail form and include:

− Hydraulic Servo Module (HSS and VP800)

− Turbine Protection Module (TPS and TP800)

− Turbine Auto Synchronization Module (TAS and AS800)

− Condition Monitoring Module (CMM and MCM800)

Intelligent HART I/O

HPC800 controllers seamlessly integrate HART field

devices through the HAI805 and HAO805 HART 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 HPC800 controller. Real time use of this

data is practical because of the modules’ individual HART

modem per channel design. Data can be calculated, used as

part of a control strategy, or for display and alarm purposes

at the S+ Operations console.

HPC800 HART capabilities allow users to take full advantage

of their HART instrumentation investments. Too often smart

devices are under-utilized instruments because of the
