Engineering Manual
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.
