Purpose

RKNDIO IOC is the IOC for logic control for RIKEN FE PLC interactions.

Created as part of Ticket #3267.

Setup

To interact with the device (an Arduino Uno) you need to follow the following steps:

1. Download the Arduino IDE from https://www.arduino.cc/en/Main/Software. Select the windows zip file to download.

2. Next, update the drivers for the device.

   • To do this connect the device via USB.
   • Then open device manager as administrator.
   • Select Ports (COM & LPT).
   • Select the port the device is plugged into.
   • Right-click on the device port and select update driver.
   • Select Browse my computer for driver software.
   • Navigate to the Arduino folder you just downloaded and select drivers folder within it.
   • Click Next and agree to install the Arduino driver.

3. Now download the specific Arduino sketch and libraries from https://github.com/KathrynBaker/se-arduino-devices (as of 29/06/2018) and copy the content into your Arduino folder which contains the arduino.exe file

4. Finally, start the arduino.exe file to start the Arduino IDE and load the RikenFEDIO.ino sketch onto the device. Now you should now be able to communicate with the device.
