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

Setting up a PCM600 project

  • The plant structure is built according to the substation structure.
    Note: The maximum size of a project is 180 IEDs. However, in order to maintain good performance and usability of the tool, it is recommended to divide one big project into multiple smaller PCM600 projects.
  • 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 the Application Configuration tool is saved to make the interfaces and signals available for other engineering tools within PCM600, for example, for the Parameter Setting tool.

Parameter setting and configuration in the Parameter Setting tool

  • Configuration parameters such as CT and VT conversion values of the transformer module are checked by the tool.
  • If needed, the setting values are checked and adjusted with the Parameter Setting tool.

LHMI engineering

  • The LEDs are configured with Application Configuration.
  • The LED behavior is defined with Parameter Setting.

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 directly suitable, in most cases, for IEC 61850 client configuration. Either IEC 61850 Configuration tool or separate engineering tools are required 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.
Note: The protection relay supports engineering from both the front and the rear port. For details, see Table 1.
