To take advantage of the network synchronization and network redundancy features of the
FieldDAQ device, ensure that your network infrastructure meets certain requirements:
•
IEEE 802.1AS-2011 time-based synchronization support
—Automatically
synchronizes timebases and enables the use of time-based triggers and multi-device tasks
between device across the network.
•
IEEE 802.1Q (Rapid Spanning Tree Protocol) support
—Supports network
redundancy functionality in ring and star topologies
–
Rapid Spanning Tree Protocol (RSTP) enabled
–
Bridge Protocol Data Units (BPDU) Guard disabled

Connecting to a Real-Time Controller
You can use the FieldDAQ device as expansion I/O from certain NI Linux Real-Time
controllers. Discover and configure the NI Linux Real-Time controller in NI MAX, then
discover and configure the FieldDAQ device.
Note
When using an NI Real-Time controller as the host, you can only use select
controllers with the NI Linux Real-Time operating system that support NI-DAQmx.
Supported NI Linux Real-Time controllers include the IC-317
x
, cRIO-9035/9039
Sync, cRIO-904

, and cDAQ-9132/9133/9134/9135/9136/9137 for LabVIEW
Real-Time.
