# X20CS1070 + X20BC0073 - Simple Example

The X20CS1070 supports CanIO, but only in “stream” or “cyclic stream” mode.

Another option is to use X20IF1072.

# Project

Don’t forget to activate Terminal Resistors for the X20CS1070 card and for X20BC0073. GUID : [e8ba3e97-c49f-4a7e-8089-b23731d309fd](https://help.br-automation.com/#/en/6/hardware%2Fx20bc0073%2Fabschlusswiderstand.html)  
The CAN interface must be set : “Activate interface = ON”
