Table 1478: Test mode
Test mode Description
Normal mode Normal operation
IED blocked Protection works as in "Normal mode"
but the ACT configuration can be used
to block physical outputs to process.
Control function commands are
blocked.
IED test Protection works as in "Normal mode"
but protection functions work in parallel
with test parameters
IED test and Protection works as in "Normal mode"
blocked but protection functions work in parallel
with the test parameter. The ACT
configuration can be used to block
physical outputs to process. The control
function command is blocked.
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.

Application configuration and Test mode

The physical outputs from control commands to process are blocked with "IED
blocked" and "IED test and blocked" modes. If physical outputs need to be blocked
from the protection, the application configuration must be used to block these signals.
The blocking scheme needs to use BEH_BLK output of PROTECTION function
block.
Control mode
The mode of all logical nodes located under CTRL logical device can be set with
Control mode. The Control mode parameter is available via the HMI or PCM600 path
Configuration/Control/General. By default, Control mode can only be set locally
through LHMI. Control mode inherits its value from Test mode but Control mode
