It is possible to follow a different sequence based on the information available at the start of the project. This means that several iterations may be needed to complete the project.

PCM600 project setup

  • The plant structure is built according to the substation structure.
  • To add a protection relay to a project, a suitable connectivity package is needed. Protection relays can be added either while connected or disconnected or through other means such as an IED template.
  • IED objects are uniquely named within the PCM600 project.

Application configuration in the Application Configuration tool

  • Protection and control functions can be configured as needed.
  • The configuration made in Application Configuration is saved to make the interfaces and signals available for other engineering tools within PCM600, for example, for Parameter Setting.

Parameter setting and configuration in the Parameter Setting tool

  • The setting values are checked and adjusted with the Parameter Setting tool.

HMI engineering in Graphical Display Editor

  • It is possible to create new pages, configure pages by adding widgets, set page visibility to different user categories, create single-line diagrams (shown on the LHMI and the WHMI) and symbols, and to provide language translations for the LHMI elements.

Communication protocol engineering

  • The communication engineering details are protocol-dependent.
  • The connectivity package creates the IEC 61850 configuration for vertical communication automatically and it is often directly suitable for IEC 61850 client configuration. Either IEC 61850 Configuration tool or IET600 is needed for configuring horizontal and vertical communication.
  • The Communication Management tool is used for other protocols; for example Modbus.
Note: The protection relay restarts automatically when writing a relay configuration where changes have been made. It is not possible to communicate with the protection relay during restart.
