Various SEL-2030 control points are available as coils that can be both operated on and read.
These control points map to remote bits within the SEL-2030. A Modbus Force Single Coil ON
message causes the corresponding SRB bit to be pulsed. A Modbus Force Single Coil OFF
message causes the corresponding CRB bit to be pulsed. These bits can be used within the
SEL-2030 for whatever control purpose you desire. When reading control points, the SEL-2711
responds with the state corresponding to the most recent Modbus Plus operation; it does not
necessarily correspond to the state of the remote bit within the SEL-2030 because it may be
modified by other operations. The following table lists these control points.
