Connecting the NI 9144 to an NI Master Controller
Before you connect the NI 9144 to an NI master controller, you must setup and connect the NI
master controller to a network. Refer to your master controller documentation on ni.com/
manuals for setup information.
NI recommends that you install a private network segment for your deterministic Ethernet
expansion devices. Slave devices cause network flooding on a standard network. Non-
EtherCAT frames jeopardize the system performance and determinism on an EtherCAT
network. Refer to the EtherCAT Technology Group Web site at
www.ethercat.org
for more
information.
