The method of Figure 7.6 can be extended to monitor multiple commands
from a station, controlling multiple output indicators as necessary.
However, where more than one command is being sent from a station, the
use of multiple output indicators may not be practical. In this instance, a
single output indicator can be used to signal all REMOTE or LOCAL
FAULT conditions for commands from that station. Figure 7.7 shows a
method for fault indicator control assuming multiple commands.
