ABB RELION REX640 - 11.8.1 Functionality; 11.8.2 Application configuration and Test mode

11.8 Test mode
11.8.1 Functionality
The mode of all the logical nodes in the relay's IEC 61850 data model can be
set with Test mode . Test mode activation method can be changed via parameter
Configuration> System> Test mode selection. Available activation methods
are "Local", "Local+remote, maintenance", "Local+Remote, all levels" and "Binary
input". By default, Test mode activation method is "Local" which means the test
mode can be activated only via LHMI through parameter Tests> IED test>
Test mode. The remote activation method via binary input or via IEC 61850
communication is possible (LD0.LLN0.Mod). When the binary input is selected
as the test mode activation method, the behavior can be configured with the
application configuration.

TRUE TRUE
See function block Protection for more details.
The behavior data objects in all logical nodes follow LD0.LLN0.Mod value.
If "Normal mode" is selected, the behavior data objects follow the mode
(.Mod) data object of the corresponding logical device.
Vertical and horizontal communication is not blocked by the “IED
blocked” or “IED test and blocked” modes.
11.8.2 Application configuration and Test mode
The breaker and disconnector outputs from control commands to process are
blocked with ”IED blocked” and “IED test and blocked” modes. If physical outputs
