ABB Symphony Plus SD Series HPC800 controller

product development process. The DSAC test facility uses

state-of-the-art open source, commercial and proprietary

robustness and vulnerability analysis tools in its certification

testing. All Symphony Plus Ethernet-based devices -

including SD Series products such as the HPC800, and

CI850 - are continually tested at the DSAC center in different

configurations and with an explicit focus on operational

performance. This ensures that all Symphony Plus products

are robust, secure and of the highest quality.

Powerful process controller

The HPC800 is the latest in a long line of field-proven

process controllers. Based on a 256 MHz, 32-bit Freescale

Coldfire processor, the HPC800 controller can be adapted to

a broad spectrum of applications and process requirements.

Configured by S+ Engineering tool, the HPC800 features

an extensive library of more than 150 pre-defined control

algorithms or function codes (figure 3). These functions

provide the ability to easily design complex control strategies

to fi t any control application, including continuous, sequential,

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
