Whether PXI can be used for Event data logging in an electrical Substation ?

[Mani]

Whether the NI PXI system can be used for recording digital event data with 1 ms accuracy ?Whether its DI boards support onboard timestamping ? Whether PXI can be synchronized with time pulses from a GPS receiver ?

Yes indeed, there is a digital event recorder example in developer zone, search for "digital time interval" on NI developer zone, or follow this link: http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3DCA356A4E034080020E74861&p_node=DZ52336&p_submitted=N&p_rank=&p_answer=&p_source=External

In addition, we have done additional work to create a template for the LabVIEW FPGA, http://sine.ni.com/apps/we/nioc.vp?cid=11829〈=US
which has 96 digital I/O lines as well as 8 analog in. With the NI-7831R you are able to combine analog and digital events in the electrical substation.

Further, using PXI, we can synchronize with a GPS time stamp such as IRIG-B, and perform these functions all in a headless - real-time OS LabVIEW.

I woul
d be happy to discuss your application in more detail and offer a complete solution, or a recipe to create the solution yourself.

Thanks for the question,
