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.
