REX640 Engineering Manual

When the protection relay is not available or is not connected to PCM600, engineering can be done offline. The offline configuration in PCM600 can be written to the protection relay later when it is connected.

Working in the offline mode has an advantage over the online mode because the preparation for the configuration can be started even though the protection relay is not available.

  1. In the Plant Structure view, right-click the bay, point to New, point to the relay application area such as Multiapplication IEDs and select the protection relay type to be inserted.
    Tip: Alternatively, drag an IED from the Object Types view to the bay level.
  2. On the Configuration mode selection page, select Offline configuration and click Next.

    Setting up an IED in the offline mode is similar to the online mode; however, with the offline mode it is not necessary to type the correct IP address in the IP address box.

  3. On the Composition code selection page, select the correct composition codes and click Next.
    Note: Ensure that the composition code is correct. PCM600 verifies that the composition code matches the relay. If the composition code digits related to the configuration, I/O or version do not match the relay, PCM600 does not allow writing the configuration to the relay. If other digits in the composition code do not match, PCM600 highlights the mismatch with a dialog box.

    • Copy and Paste are used to copy or paste the composition code from the relay ordering tool to Configuration Wizard, or from Configuration wizard to the relay ordering tool.
    Figure 3. Example of visual guidance in composition code selection

    User is visually guided to make accepted selections. Invalid module selection will be highlighted according to figure 30.

  4. On the Configuration Selection Page, select the configuration type and click Next.
    • Select Empty configuration to create an empty configuration.
    • Select Import configuration from file (APCMI/APCMT) to import an example configuration.

      Click Browse to select the .pcmi/.pcmt file that has the example configuration.

  5. On the Version Selection page, select the IEC 61850 version and click Next to generate the functions.
  6. The Summary page shows the summary of the IED type, IP address and the selected composition code. Click Finish to confirm the configuration and conduct the insertion.
