REX610 Technical Manual

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 Main menu > Tests > IED test in the LHMI. Local/Remote control must be set to "Local" to change Test mode via LHMI.

Test mode is also available via IEC 61850 communication. Local/Remote control must be set to "Remote" to change Test mode using IEC 61850.

Note: See the CONTROL function block for more details.

Protection

BEH_TST

Normal mode

Normal operation

FALSE

FALSE

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.

TRUE

FALSE

IED test

Protection works as in “Normal mode” but protection functions work in parallel with test parameters

FALSE

TRUE

IED test and blocked

Protection works as in “Normal mode” 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.

TRUE

TRUE
Note: See the PROTECTION function block for more details.
Note: 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.
Note: Vertical and horizontal communication is not blocked by the “IED blocked” or “IED test and blocked” modes.
