Bits Information
Table C.15 lists the Relay Word bit data available in the SEL communications
processor TARGET region.
Control Points
The SEL communications processor can automatically pass control messages,
called Fast Operate messages, to the SEL-700G. You must enable Fast
Operate messages by using the FASTOP setting in the SEL-700G port settings
for the port connected to the SEL communications processor. You must also
enable Fast Operate messages in the SEL communications processor by
setting the automessage setting SEND_OPER equal to Y.
When you enable Fast Operate functions, the SEL communications processor
automatically sends messages to the relay for changes in remote bits RB01–
RB32 on the corresponding SEL communications processor port. In this
example, if you set RB01 on
Port 1
in the SEL communications processor, it
automatically sets RB01 in the SEL-700G.
Breaker bits BR1 and BR2 operate differently from remote bits. There are two
breaker bits in the SEL-700G. For Circuit Breaker n, when you set BRn, the
SEL communications processor sends a message to the SEL-700G that asserts
the OCn bit for one processing interval. If you clear BRn, the SEL
communications processor sends a message to the SEL-700G that asserts the
CCn bit for one processing interval. OCn opens the breaker (via SEL
OGIC
control equation TR x) and CCn closes the breaker (via SEL
OGIC
control
equation CL x). See Figure 4.126 and Figure 4.130 for the breaker trip and
breaker close logic diagrams, respectively.
