How to test

Setting slave outputs on master (2/2)

ACTION

1. Right click on OUT_GEN_INT1 of the slave node and select

„Online Write…“ inside the context menu. Change the value from 0

to 50000.

OBSERVATION

1. Brightness of LED2 on „XMC4800 Relax EtherCAT

Kit“ is

dimmed. Setting OUT_GEN_INT1 to 65535 the LED2 is turned off.

The lower the value, the brighter the LED2.
