National Instruments FAQ — DAQ Replacement, PXI Integration & Controller Compatibility

Can NI DAQ modules replace legacy units without modifying LabVIEW code?
Often yes — when I/O type, channel configuration, and driver revision match. We verify the required NI-DAQmx interface to ensure a seamless swap.

Can NI PXI cards interface with third-party systems?
Yes — using supported buses such as Ethernet, CAN, RS-232/485, and industrial field protocols. Driver mapping and instrument control must be confirmed ahead of time.

Can National Instruments controllers communicate with PLC-based automation?
Yes — via MODBUS, EtherCAT, OPC UA, and similar protocols. We confirm register mapping and sample rate requirements for deterministic communication.

Are NI I/O modules interchangeable across different chassis models?
Only when backplane power, data bandwidth, and slot specification match. Some revisions require model-to-revision verification before use.

Can NI timing/motion modules support servo or machine-level control?
Yes — with appropriate motion hardware, encoder feedback, and deterministic timing control. We confirm loop speed and resource allocation for motion applications.

Can you replace an NI DAQ card without rewriting our LabVIEW program?
Often, yes — we match I/O channels and DAQmx driver requirements for direct compatibility.

Can NI hardware connect to third-party automation systems?
Yes — we verify protocol and driver compatibility for integration with PLCs and industrial control networks.

Can NI controllers operate alongside PLC-based control?
Yes — standard fieldbus networks enable hybrid control and synchronized data exchange.

Will NI modules work in a newer PXI or cDAQ chassis?
Sometimes, we confirm slot power, timing, and bus requirements first.

Can NI modules support motion control and machine automation?
Yes — we identify suitable motion/timing hardware to meet servo or robotics requirements.
