ABB Symphony Plus SD Series PROFIBUS Interface PDP800

Symphony® Plus is the next generation of ABB's acclaimed Symphony family of centralised control systems.

There are more than 6.500 Symphony centralised control systems in operation around the world, including more than 4.500 in the power and water industries.

No other automation platform in power and water applications has such a long history and large installed base as Symphony.

For more than 30 years, ABB has evolved the Symphony family of products, ensuring that each generation enhances the capabilities of its predecessor.

and backward compatible with its predecessor, all in line with ABB's long-held policy of ‘evolving, never outdated’.

Symphony Plus includes a complete set of standards-based control hardware and software for plant-wide automation requirements.

The SD series PROFIBUS interface PDP800 provides the connection between the Symphony Plus controller and the PROFIBUS DP communication channel.

This allows easy integration of intelligent devices such as smart transmitters, actuators and intelligent electronic devices (IEDs).

The information resident in each device can be used for control strategies and higher-level applications.

In addition to providing a tighter, more reliable process control solution, the PDP800 PROFIBUS solution reduces installation costs by reducing cabling and system footprint.

System costs can be further reduced by using S+ Engineering to configure and maintain the PROFIBUS network, devices and their associated control strategies.

SD Series PDP800: Redundant Configuration

Seamless Intelligent Field Device Integration

Symphony Plus controllers seamlessly integrate field devices via the PDP800 PROFIBUS interface module.

This allows access to a wide range of intelligent field devices, including transmitters, actuators, motor control centres (MCCs), flame scanners, intelligent electronics and more.

These devices come from ABB and other third-party vendors.

PROFIBUS I/O and associated control strategies are configured using ABB's extensive field-proven standard function code algorithms and S+ Engineering's graphical design tools.

In addition, these data are made available to other S+ system nodes (i.e. Control, Operations, Engineering and Information) via a redundant plant network (PN800).

PDP800 PROFIBUS interface features include

- Support for PROFIBUS DP V0. V1. V2

- Support for PROFIBUS PA devices via DP/PA linked devices

- Support for 1 ms device timestamps via PROFIBUS DP V2

- Support for electrical and fibre optic media for PROFIBUS DP links

- PROFIBUS DP link rate up to 12 Mbps

- PROFIBUS DP connections over fibre optics up to 15 km

Comprehensive I/O Support

The PDP800 module connects Symphony Plus controllers to the S800 I/O via PROFIBUS DP V2. The S800 I/O offers options for all signal types.

The S800 I/O offers options for all signal types, from basic analogue and digital inputs and outputs to pulse counters and intrinsically safe applications.

PROFIBUS DP V2 supports the S800 I/O Event Sequence function, which time stamps events at the source with a 1 ms accuracy.

In addition, the PDP800 supports the connection of Symphony Plus controllers to S+ Turbine dedicated modules.

Specifically, via PROFIBUS DP V2. the HPC800 supports powerful turbine control solutions.

such as turbine protection (TP800), valve positioning (VP800), automatic synchronisation of generators (AS800) and condition monitoring (MCM800).

With fibre-optic extension, PROFIBUS I/O modules and devices can be placed up to 15 km away from the PDP800.

In addition, the PDP800 modules can be located up to 3 km away from the controller via redundant HN800 fibre optic communication.

High reliability and availability

The PDP800 supports full redundancy at all levels, including the PDP800 module, power supply, PROFIBUS DP link, and controller communication bus (HN800).

All redundancy options are independent of each other to ensure the highest level of availability and reliability.

Data Accessible to Control Applications

The functionally coded control application in the Symphony Plus controller has access to PROFIBUS device cycle data.

The data can be calculated, used as part of a control strategy, or displayed and alarmed at the S+ operator console.

An overview of the functions of the PDP800 is shown in Figure 2.

Managing Intelligent Field Devices

PROFIBUS devices are fully integrated into the Symphony Plus system, bringing benefits that go far beyond reduced footprint and cable costs.

In the S+ Engineering Workbench, field engineering tools support configuration, commissioning and maintenance of PROFIBUS devices using Device Type Manager (DTM) technology.

For field devices with a conventional device description file (GSD), standardised configurations are possible using the basic PROFIBUS DTM.

Individual device DTMs can be accessed from multiple data views (e.g. system or location overview, etc.) in Composer.

It includes automatic calculation of net values and loading of process items by using the device-specific channel configuration generated from the DTM.
