\section{Monitoring}
\subsection{Connectivity}
\begin{itemize}
\item The task {\tt EIB$\_$Start$\_$PingTask} monitors the connection to the EIB74x hardware
and writes the status into the PV \PV{EIB:CONNECTED}. If the connection is interrupted it peridically tries to reconnect.
\item After reestablishing the connection, the status of the index marks is read and the HOMED flags of the encoders are set accordingly.
\item If the EIB was powercycled, the HOMED flags are set to FALSE.
\end{itemize}
The same procedure applies after a restart of the softioc.
By this, the necessity of an new index search is avoided.
\subsection{Signal loss}
\begin{itemize}
\item When an encoder is disconnected while the softioc tries to read it, the EIB sets the flag "signal amplitude error" in the encoder status.
The softioc indicates this in the \PV {EIB:CH$\_$x$\_$SIGNALERROR}.
\item Unfortunately, this works only when the encoder readout happens during the time when the encoder is disconnected.
If the encoder is removed and reconnected between two readouts, the encoder status does not reflect this in the "signal amplitude error" flag.
\item What can be seen is that the status reports an "Frequency exceeded" in that case.
This could be reported to the user with a recommendation to start an index search.
\end{itemize}
