Standardized, general communication

General time synchronization

One control hardware platform i.e. SICAM 1703 ACP

One SCADA system i.e. 250 SCALA

One tool i.e. Toolbox II

Reduced maintenance (selfdiagnosis)

Remote access for customer and/or Supplier

Advantages of the Integrated Network Concept [2]

Step by step implementation of subsystems or functional areas or

implementation of total solutions

Reduction of I/O-hardware and cabling

Reduction of engineering, erection works and documentation

Reduction of spare parts by using one hardware system family

More information about current power plant state

Reduced training for operator and maintenance staff

Integration of new services

Summary

Increase of annual power output

Integrated optimization

Increased Availability (self-diagnosis)

Application of power plant management

Reduced total cost of ownership

Reduced investment costs

E.g. one communication network

Step by step commissioning

Minimized operation costs

Reduced maintenance

Reduced Downtimes by remote access

Reduce spare parts by decreased product variety

Reduced training
