Behavior data objects under CTRL logical device follow
CTRL.LLN0.Mod value. If "On" is selected, 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. 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 only by setting the Remote test mode parameter via Tests/IED test/
Test mode. Remote operation is possible only when control position of the relay 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
• Control position of the relay is in remote position
