Looking to use newer cRIO-905x controller for a project. All modules will be operated in real-time (DAQmx) programming mode. Additionally, I will need several remote chassis for DAQ IO. Since I'm using the DAQmx programming mode, is it acceptable (or recommended) to use a cDAQ chassis (like cDAQ-9185)? The Newark tech. support engineer in India recommended a cRIO chassis (NI-9147) but it appears it only operates with Scan and FPGA programming modes.. neither of which I want to use.
Additionally, if cDAQ chassis is a good choice, then what is the best means of communication between cRIO controller and the multiple cDAQ chassis? In a NI Week video from a few years ago, it mentioned a daisy chain connection. The Newark engineer then mentioned an Ethernet device for a star-type connection.. don't know if he recommended a hub, switch, or router. If using TSN for synchronization, would one or the other be required?
Thanks in advance for assistance! I can no longer get tech. support on the phone at NI since they've gone to the Distributor model, so I'm scrambling to get answers for my system.
