On my desk in my room at the present, I scatter

five EhterCAT slaves, 10 meters Ethernet cables, four 24V LED lights, sensors device of temperature, human detector, luxmeter, four bread boards and several transistor IC

For the final stage of EtherCAT serialisation, I am preparing for these cable and devices, in order to install the home security system on the Ebata's house.

There are two communication systems that has already installed on my house. One is for the Internet service, and the other is for the outdoor monitoring system.

My wife looks uneasy. She is likely to ask me

"Are you going to do anything moreover ?"

I put my wife at ease with saying "It is no problem. This is just a temporally experiment installation."

-----

I am afraid that the day of the completion date is not decided at the present.

It is same as the existing systems.
