Release of IED Connectivity Package Ver. for Switchsync PWC600

Switchsync PWC600 is Hitachi Energy's newest generation of point-on-wave controllers, based on the successful Relion® 650 series, version 1.3, of protection and control products. Offering the full functionality and reliability of previous Switchsync products, it additionally comes with Ethernet interfaces, which support modern communication standards, and enhanced functionality towards the user.

Switchsync PWC600 is designed for single-pole operated circuit breakers, controlling each pole to close or open at the point on wave that is optimal for the switched load, the circuit breaker, or power quality.

Switchsync PWC600-M 1.0 controlled switching applications (essential switching operation in parentheses):

  • Capacitor bank (energization)
  • Shunt reactor (de-energization)
  • Power transformer (controlled energization supported by controlled de-energization)
  • Transmission line or power cable (energization)

New features and benefits

This version of the IED Connectivity Package (IED ConnPack) enables the interaction between the Switchsync PWC600 version 1.0 IEDs, which is based on Relion® 650 series version 1.3, and the Protection and control IED manager PCM600 version 2.5 or later.

IED ConnPack enables handling of cybersecurity related information such as IED user management and reading of security events from the Switchsync PWC600.


The supported feature includes

  • Switchsync Setting Tool (SST) – A wizard for the easy configuration of the PWC600-M application
  • Support for multiple PCM600 2.x versions on the same computer

The new features included in SST are

  • Support for additional Hitachi Energy circuit breaker models, for easy configuration
  • Mechanical monitoring limits are defined as deviations from nominal circuit breaker timings

Note: While opening an existing IED in PCM600 project with this revision of the Connectivity package, the limits of mechanical supervision, which are part of circuit breaker data, will get updated. Therefore, it is highly recommended to take a backup of the project before opening SST, after this version of the Connectivity package has been installed.
