This HMI update makes the Flash Media Update process go a bit more smoothly.
\end{abstract}

\section*{System Requirements}
The flash media update process has been extensively tested with different versions of IDEC firmware.
The firmware on your IDEC PLC must be version 2.10, or later to perform the updates properly.

\section*{Changes to the process:}
The process is largely the same. You still need to update the HMI with a USB media stick.
This will give you access to the PLC software update page.

The PLC Update process still uses an SD Card with the following format:
\begin{verbatim}
FCDATA01 -> PROGRAM -> softwareUpate.zld
FCDATA01 -> autoexec.ini
\end{verbatim}
but now you have a GUI to help you perform the update.

\section*{Instructions}
From the System Software update page:
you will see a listing for your PLC Firmware version on the top left side of the HMI.
If this number is lower than 2.10, the Flash Media Update process will not succeed.


The PLC Software versions on the and HMI software Versions are listed below.

Insert your Flash Media Update SD Card. The SD LED on the PLC will flash rapidly while the SD Card mounts.
when the rapid flashing stops, you may press the UPDATE button to update the PLC system software.

If the SD Card is not recognized, or not formatted correctly the update button will not be click-able.
\\
Once clicked, the UPDATE Button will change color, and read: UPDATING.
\\
When complete, the button will return to say UPDATE.
The UPDATE button will no longer be clickable.
\\
Please power off the PLC, Eject the Flash Media Upgrade SD Card,
and power on the PLC.
\\
Your listed software versions will now be updated.
