We are going to setup an KIC KUNBUS-IC EtherCAT Module as SPI Slave mode.

The SPI Master we are using is an Arduino DUE.

We are using the following equipment

• A KUNBUS-IC Module (I.e. EtherCAT PR100035)

• KIC Evaluation Board (I.e. Ethernet Based, PR100079)

• Arduino Due

• PuTTy Software Terminal

Hardware Setup

...

1. Connect the KIC Module with the Evaluation Board

2. Setup the power supply i.e. 3.3 Volts

3. Connect the CDI RS232 interface with your PC

4. Run “devmgmt.msc” to open the device manager and see which COM port is used i.e COM4.

5. Connect the wires from the Evaluation Board to the Arduino Due
