The mode of all logical nodes located under CTRL logical device are set with
Control
mode
.
Control mode
is selected 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
”On”,
“Blocked” and “Off” can also be independently set.
Control mode
is also available via
IEC 61850 communication (CTRL.LLN0.Mod).

According to IEC 61850, the physical outputs to process should be blocked when
device is set to blocked or test blocked mode. The usage depends heavily on the actual
ACT configuration. In the protection blocking example the main trip from
TRPPTRC1 is blocked, and in the control blocking example the CBXCBR1 is
blocked. Both comply to the IEC 61850. In real applications some of PTRC’s might
also be used for signalling purposes (GOOSE) and blocking and interlocking via IO.
The physical outputs to process can be blocked with “IED blocked” and “IED test and
blocked” modes. If physical outputs need to be blocked, the application configuration
must block signals or function blocks that affect primary apparatuses. Blocking
scheme needs to use the
BEH_BLK
output of the PROTECTION function block.

Control blocking example
The physical outputs to process can be blocked with “Blocked” mode. If physical
outputs need to be blocked, the application configuration must block signals or
function blocks that affect primary apparatuses. Blocking scheme needs to use
BEH_BLK
output of CONTROL function block.
