====== 2 IOL Master Application ======

To operate the IOL HAT on a Raspberry Pi, the master application binary from the IOL HAT repository is used: [[https://github.com/Pinetek-Networks/iol-hat/bin]]

<WRAP Important>

Important note on the startup order: To work properly, the master application needs to be started AFTER 24V power is applied. Failure to do so will result in broken IO-Link communication.

</WRAP>

The suitable master application file for the used Linux distribution shall be used. The Linux version can be determined with

<code bash>
uname -a
</code>

If the Linux distribution is not available as binary, please refer to the building instructrions on the GitHub page to compile a matching version:
