What is the Advised Alternative Light Weight 4 Slot cRIO to the cRIO-9047?

Issue Details

I am currently using the cRIO-9047 as the backbone of my DAQ systems. My current application is more weight sensitive, so I'm looking at a lighter alternative that can effectively serve as a drop-in replacement for the cRIO-9047. Something almost identical in every specification except slot count. I heavily rely on NI-DAQmx and TSN, and it must be a Linux system and support EtherCAT. 

Solution

Here are some potential alternatives to the cRIO-9047 that offer similar features:

1. cRIO-9040
- Slots: 4
- Processor: 1.30 GHz Dual-Core Intel Atom
- Features: Supports LabVIEW FPGA programming
- Note: The provided context does not confirm support for DAQmx, TSN, Linux, or EtherCAT.

2. cRIO-9053
- Slots: 4
- Processor: 1.33 GHz Dual-Core
- FPGA Coprocessor: Good
- Features: Supports LabVIEW FPGA programming
- Note: The provided context does not confirm support for DAQmx, TSN, Linux, or EtherCAT.

Comparison of 904x and 905x controllers:
The cRIO-904x and cRIO-905x both offer 4-slot configurations and support LabVIEW FPGA programming. However, specific support for NI-DAQmx, TSN, Linux, and EtherCAT is not detailed in the provided context. Further investigation would be necessary to confirm these specifications for each model.
