* x = 0: Termination resistor is not set
x = 1: Termination resistor set
NOTE
Second Address settings are only relevant if the EtherCAT master manages the addresses
of participants via the "Hot Connection Group" functionality.
Termination resistor
EtherCAT: No termination resistors need to be used on the field bus system (EtherCAT)
System bus:
The termination of the BUS system is made at both of its physical ends by connection of
the relevant termination resistors (DIP switches).
