The network setup needs to be done in `1 TCP/IP` -> `TCP/IP` -> `Detailed Setup`. 

It is necessary to change the network communication of the fanuc according to your network. 

{% hint style="warning" %}
Make sure, that the robot and robobrain® system are in the same IP address range and the subnet mask is matching the IP address settings.
{% endhint %}

Create a new host to enable the communication between the robobrain® system and the FANUC controller. Name the host "RAP" and give it the iP address of the robobrain® system. 

{% hint style="info" %}
Please ensure to use the correct ethernet port on the robobrain® system.
{% endhint %}
