Depending on requirements, plant size and availability request, the integration of Intelligent Electronic Devices, e.g.: SIPROTEC protective devices or interoperable third-party devices can be performed directly on the plant bus via a station controller or a PCS 7 Controller S7-400H with (redundant) station gateway.

The integration of IEC 61850 protective devices can be carried out in different ways: straight at the plant bus, via a Station Gateway or with an own Station Controller.

The seamless integration into the SIMATIC PCS 7 engineering now allows object-oriented project planning for automation of switchgear including:

  • object library of functional modules, symbols and faceplates with the accustomed SIMATIC PCS 7 APL Look and Feel

  • technological library for electrical equipment (e.g.: feeder , motor, generator, transformer, power line)

  • automatic generation of objects for the operator station and

  • easy integration of new IEDs by importing their IEC 61850 device description (ICD)

  • Flexibility through integration of an existing PROFIBUS infrastructure.

In operation, this integration allows the use of basic control system functions such as:

  •  the archiving of process values and messages

  • time synchronization of communication devices

  • alarm management system with time-stamping at source

  • processing of events in the correct sequence and

  • standardized user management as regards access rights.
