3.7.2 Functionality
The mode of all the logical nodes in the relay's IEC 61850 data model can be set with
Test mode . Test mode is selected through one common parameter via the WHMI
path Tests> IED test. By default, Test mode can only be set locally through LHMI.
Test mode is also available via IEC 61850 communication (LD0.LLN0.Mod).
Table 38: Test mode
Test mode Description Protection BEH_BLK
Normal mode Normal operation FALSE
IED blocked Protection working as in “Normal mode”
but ACT configuration can be used to block
physical outputs to process. Control function
commands blocked.
TRUE
IED test Protection working as in “Normal mode” but
protection functions are working in parallel
with test parameters.
FALSE
IED test and blocked Protection working as in “Normal mode” but
protection functions are working in parallel
with test parameters. ACT configuration can
be used to block physical outputs to process.
Control function commands blocked.
TRUE
Behavior data objects in all logical nodes follow LD0.LLN0.Mod value. If
"Normal mode" is selected, behaviour data objects follow 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.
3.7.3 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. Blocking scheme needs to use BEH_BLK output of PROTECTION function
block.
