automation code generation of user

programs

•Integrated diagnostic system•Integrated commissioning tool




Modularity

The OM650 process control and information functions have been

subdivided into packages, which - with respect to the software involved - are further

subdivided into function blocks.

This modular design not only increases the option variations of thesystem but also improves the possibilities of optimally matching the

system to the various requirements made by plants of different sizes and

tasks. However, all tasks are processed under a common organization

structure so that a uniform user interface can be used. This common

organization provides common data management and the possibility of

common evaluation covering the entire plant without the modular design ofthe functions being apparent to the user. Distributed data management

allows almost unlimited system extension without limiting the

performance of each individual component.




TELEPERM XP Components




The TELEPERM XP (TXP) process control system provides all I&C facilities that

are necessary for automating,handling, monitoring, and archiving processes(such as the operational instrumentation and control systems of powerplants).

The tasks of a process control system are distributed to different subsystems:

- OM 650: Operating and Monitoring system. This is the process control and

information system for operator--process communication and visualization.

- ES 680: Engineering System. This system is employed for configuration andcommissioning.

- DS 670: Diagnostic System.

- SINEC H1: SIEMENS Network Communication. Communication system.

- AS 620: Automation System. This is the system used for process automation.

TXP sub systems



Homogeneous Structure from field to plant Management

The communication between OM

and AS is done via Plant bus

The internal communication within

OM is done via Terminal bus

The ES is used for configuring both

systems: OM and AS. For this

reason it is connected with bothPlant and Terminal buses

All this communication paths are

part of LAN (Local Area

Network)

Communications to external WAN

(wide Area Network) is possible

via gateways



The SINEC H1 Bus System The SINEC H1 bus system network allows intercommunication between the distributed

autonomous components of the process control system. The bus system complies with

international standards hence providing functions required for open communication.

This means that not only system components but also equipment from other product

lines or from other vendors can be connected .

The SINEC H1 is based on the standardized access procedure CSMA/CD featuring the

very high baud rate of 10 MBits/s. The bus system is available either with triaxial cable

or with fiber optic cable SINEC H1FO (Fiber Optic). The major advantage of the version

using fiber optics is that it guarantees electrical isolation between the partners to the

communication and reliable protection against electromagnetic interference.

The AS 620 Automation System

The AS 620 system executes the tasks of the group and individual control levels. It acquires

measured values and statuses from the process, carries out open-- and closed--loop controlfunctions and issues the resulting commands on to the process.

At the same time, the AS 620 represents the interface to the process for the other

TELEPERM XP systems. It transfers commands from the OM 650 operation and monitoring

system to the process, and reads in information required by the OM 650 from the process

and passes it on to the operation and monitoring level.

Corresponding to the various requirements which have to be met by measurement, open—

and closed--loop control during normal operation as well as those requirements to be met bythe safety--related tasks of the boiler and the fast changes in the turbine,

three AS 620automation system versions are available:

- The AS 620 B (Basis) for general automation tasks ranging from the protection of an

auxiliary device up to the unit co--ordination controller.

- The AS 620 F (Fail--Safe) for safety--related protection tasks (of the boiler, for

example) and controls subject to approval (such as burner controls).- The AS 620 T (Turbine) for the fast closed--loop control of the turbine.

For I&C system tasks in ancillary plants, automation devices from the SIMATIC S5 (S5--AG)

system range can be used with the corresponding standard peripheral equipment (SIM S5).

As these devices are connected to the AP automation processor, they are also integrated

into the communication system.



Important features of the OM 650 system:

•Pixel-graphics desktop (HMI)

• Uniform HMI for process control, information and management

• Operator-optimized operation philosophy

• Display of information based on plant, process and I&C aspects

• Decoupling of processing units and operating terminals

• Central configuring using the ES 680 Engineering System

• Scalable hardware and software concept

• Distribution of data and functions

• Function packages for process control, information andmanagement

• Configurable redundancy for all components

• Incorporation of international standards (UNIX, relational databasesystem with SQL interrogation language).




Important features of the ES 680 system:

• The ES 680 engineering system supports the engineering stepssystem-wide. A typical engineering procedure is as follows:

• Entry of project data (e.g. plant name, functional complexes, personresponsible, etc.)

• Equipment structure (topology, cabinet layout, module structure)

• Creation of area and overview diagrams (optional)

• Planning the function diagrams of the single-loop level(automation/log functions).




Important features of the DS 670 system:

• Automatic detection and acquisition of I&C faults

• Conditioning of the detected faults and compressed presentation(alarm compression) in graphical form within an I&C equipmentstructure display

• Interactive user guidance to the fault (localization) through theequipment structure

• Presentation of the fault in graphics and text with detailedinformation and, if possible, with suggestions for repairs

• Log, statistical and evaluation functions

• Provision of I&C-related information, such as

- I&C equipment structure

- Automation system and cabinet configuration- Versions for hardware and software.
