ABB PDP800 SD Series PROFIBUS Interface

ABB PDP800 SD Series PROFIBUS Interface

DESCRIPTION

Symphony® Plus is the new generation of ABB’s widely acclaimed  Symphony family of distributed control systems – the world’s most  widely used DCS in the power generation and water industries.  In all, there are more than 6,500 Symphony DCS installations in  operation all over the world, more than 4,500 of which are in power  and water applications.

Seamless intelligent fi eld device integration

Symphony Plus controllers seamlessly integrate field devices  through its PDP800 PROFIBUS interface module. This allows  access to a wide range of intelligent field devices including  transmitters, actuators, motor control centers (MCC), flame scanners, intelligent electronic devices, etc, from ABB  and other third-party vendors. PROFIBUS I/O and related  control strategies are configured using ABB’s extensive set  of field-proven standard function code algorithms and  S+ Engineering’s graphical design tools. Furthermore, this data  is provided to other S+ system nodes (ie, control, operation,  engineering and information) over the redundant Plant Network  (PN800).

PDP800 PROFIBUS interface features include:

− Supports PROFIBUS DP V0, V1, V2 

− Supports PROFIBUS PA devices through DP/PA linking device 

− Supports 1 msec time stamping of devices by PROFIBUS DP V2 

− Supports electric and fi ber optic media for PROFIBUS DP link 

− Up to 12 Mbps rate of PROFIBUS DP link 

− Up to 15 km by fi ber optic PROFIBUS DP link

Comprehensive I/O support

The PDP800 module enables the connection of Symphony  Plus controllers to S800 I/O via PROFIBUS DP V2. S800 I/O  provides options for all signal types, ranging from basic analog  and digital inputs and outputs to pulse counters and intrinsically  safe applications. S800 I/O sequence of events functionality is  supported by PROFIBUS DP V2 with 1 msec accuracy event  time stamping occurring at the source.

Additionally, the PDP800 supports Symphony Plus controllers’  connectivity to S+ Turbine’s specialty modules. Specifi cally, via  PROFIBUS DP V2, the HPC800 can support powerful turbine  control solutions for turbine protection (TP800), valve positioning  (VP800), generator auto synchronization (AS800) and condition  monitoring (MCM800).

Using fi ber optic extensions, PROFIBUS I/O modules and devices  can be placed up to 15 km from the PDP800. Additionally,  PDP800 modules can be located up to 3 km from the controller  via redundant HN800 fi ber optic communications.

High reliability and availability

The PDP800 supports full redundancy at all levels, including  the PDP800 module, power supplies, PROFIBUS DP link, and  controller communication bus (HN800). All redundancy options  are independent from each other to ensure the highest level of  availability and reliability

Data accessible by control application

PROFIBUS device cyclic data is accessed by function code  control applications in Symphony Plus controllers. Data can be  calculated, used as part of a control strategy, or for display  and alarming at the S+ Operations console.

Manage intelligent field devices

PROFIBUS devices are fully integrated with the Symphony Plus  system, yielding benefits far beyond reduced footprint and  cable costs. Within the S+ Engineering workbench, the Field  Engineering tool supports configuration, commissioning and  maintenance of 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. The individual  device DTMs can be accessed from Composer’s multiple data  views, such as the system or location overview, and others. It  includes automatic net calculation and loading of process items  by using the device-specific channel configuration generated  from the DTM.
