REX610 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 compared to online mode in that 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 as in the online mode; however, with the offline mode it is not necessary to type the correct IP address in the Communication port and IP address dialog box.

  3. On the IEC 61850 communication settings page, select the USB port.

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

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