Hi Paul,

The "Secondary slave address" is used for this purpose. The slaves address is programmed with "ethercat alias".
For usage in your application code see ecrt.h.

Hi,

If I want to access a slave on the Ethercat bus, we use the position of
the slave on the bus to access it with ecrt_master_slave_config(). If we
then put a new slave on the bus before this slave for example, this
means that the position number of the first slave will change and we
need to reconfigure our code.? This presents problems.

My question is, can we not access the slave via their physical addresses
instead of this incremental position addressing, therefore not needing
to update the position address every time there is a change?

Thanks
