values "On", "Blocked" and "Off" can also be set independently. Control mode is also
available via IEC 61850 communication (CTRL.LLN0.Mod).

The behavior data objects under CTRL logical device follow
CTRL.LLN0.Mod value. If "On" is selected, the behavior data objects
follow the mode of the corresponding logical device.

Application configuration and Control mode

The physical outputs from commands to process are blocked with "Blocked" mode. If
physical outputs need to be blocked totally, meaning also commands from the binary
inputs, the application configuration must be used to block these signals. The blocking
scheme uses BEH_BLK output of CONTROL function block.
Authorization
By default, Test mode and Control mode can only be changed from LHMI. It is
possible to write test mode by remote client if it is needed in configuration. This is
done via LHMI by setting parameter Test mode selection via Tests/IED test/Test
mode. Remote operation is possible only when the relay's control position is in remote
position. Local and remote control can be selected with R/L button or via Control
function block in application configuration
When using the Signal Monitoring tool to force online values, the following
conditions need to be met.
• Remote force is set to "All levels".
• Test mode is enabled.
• The relay's control position is in remote position.
