[etherlab-users] Fw: ETHERCAT Bus Coupler Question

[aj]

So as Sebastian suggested , I will use I/O Coupler from Beckhoff why make
my life harder 😊

Thanks for the ifo.

regards,
ajith

PS: The forum serves its purpose, helps to make informed decisions to new
comers, cheers folks!! keep up the good work, I shall definetely report my
Progress.
