7.5.5 Selecting IED blocked or IED test and blocked mode
The IED blocked mode and the IED test and blocked mode can be activated using
the LHMI. The Home button flashes green when the device is in the IED blocked or
IED test and blocked mode. By default, the test mode can only be changed from the
LHMI. Activation by remote client is possible, see the technical manual.
The test mode can be used for simulated testing of functions and outputs without
providing current inputs. The IED blocked mode can be used to block the physical
outputs to the process.

7.6 ABB Product Data Registration
The ABB Product Data Registration feature traces composition changes in the
protection relay's SW or HW. Traceability allows better support and maintenance
possibilities.
Protection relay detects hardware or software change and stores this information
internally. This information can be read from relay using PCM600 Lifecycle
Handling> Collect IED Composition Data.
Composition data is automatically transferred to ABB if feature is enabled during
the PCM600 installation.
