• Operate irrespective of the L/R switch position.
• Select time is configurable.
• SPC points support both DIRECT (Direct Operate) and SBO (Select-Before-
Operate).
LED output points only support latch off and trip commands. An error
will be returned by the IED if latch on or close is sent to an LED
output.
DPC based CROB, for example, breaker control:
• Operation is blocked unless IED is in the remote switch position.
• Select time is configurable.
• DPC point DIRECT/SBO behavior is determined by the Control_model
parameter in REF615/Configuration/Control/CBXCBR1/Control_model.
1. The DNP stack accepts SBO commands if the Control_model parameter
is configured for "sbo-with-enhanced-security".
2. DIRECT commands are accepted if the parameter is set to "direct-with-
normal-secruity".
3. Otherwise, the command violates the Control_model, and is rejected.

1) In this IED implementation the pulse-on time cannot be commanded from the DNP 3.0 master. A value
in the variable pulse-on time field in the CROB command is ignored, but the command is accepted. It
should be noticed that control pulse lengths for CB controls in this IED are configurable via PCM600.
Pulse lengths for other types of outputs are in internally fixed.
