Figure 5–27: DUAL BREAKER CONTROL SCHEME LOGIC (Sheet 2 of 2)
The breaker element has direct hard-coded connections to IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each breaker, using either CSWI or XCBR IEC 61850 logical nodes. IEC 61850 select-
before-operate functionality, local/remote switch functionality along with a blocking of open/close commands are provided.
Note that IEC 61850 commands are event-driven and dwell time for these is one protection pass only. If you want to main-
tain the close/open command for a certain time, do so either on the contact outputs using the "Seal-in" setting or in Flex-
Logic.
