Classification: CPC G  H | IPC G  H

Claim 14:
15. A configurable binary circuit for use in an electrical power system, comprising:
an input/output port to at least one of receive a binary signal input as an input port or transmit a binary signal output as an output port;
a binary input subsystem for receiving the binary signal input via the input/output port operating as the input port;
a binary output subsystem for transmitting the binary signal output via the input/output port operating as the output port;
a switch subsystem for selecting one of the binary input subsystem or the binary output subsystem for operation such that the configurable binary circuit operates as either a binary input circuit when the binary input subsystem is selected or a binary output circuit when the binary output subsystem is selected;
wherein, when the configurable binary circuit operates as the binary output circuit when the binary output subsystem is selected by the switch subsystem, the binary input subsystem is programmed to monitor the output port for outgoing signals to verify that the binary output subsystem is transmitting an expected signal.
