Communication Protocol Manual
• it allows actual statuses to be included in class 0 polls,
• it allows change event reporting of the actual statuses, which is a more
efficient and time-accurate method of communicating control values,
• and it allows reporting of time-based information associated with controls,
including any delays before controls are actuated, and any durations if the
controls are pulsed.
BOS points that relate to some kind of software binary output points, that is reset-
or acknowledge points, are not looped back as binary inputs.
The default select/control buffer size is large enough to hold 10 of the largest select
requests possible.
DNP3 pulse commands, and associated count, off-time and on-time, are not
supported in this implementation.
From the IED's perspective, there are two types of CROB points. Most are
internally mapped to IEC 61850 SPC, while the breaker control is mapped to
61850 DPC.
DPC based CROB, for example, breaker control:
• Operation is blocked unless IED is in the remote switch position.
• Timeout selection is configurable.
• DPC point DIRECT/SBO behavior is determined by the Control_model
parameter in 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-security".
3. Otherwise, the command violates the Control_model, and is rejected.
