data saving in host

[maintenanace]

I have some experience with LabView but none with this hardware.i am new using CRIO system(9004).how i can save the data using crio any example for this .

There's a CompactRIO Developer's Guide here.

any example for data saving in host

[GerdW]

LabVIEW also comes with ready-to-use example projects explaining data communication between host PC and cRIO target!

[cbutcher]

See Section 6 for an overview and description of the Sample codes.

You need to use two applications: one on your cRIO and one on your host/PC.  You can send data between the applications using TCP/IP functions (look up the STM library) or Network Streams.  So using this communication, you send messages to the host telling it to save the data being sent.

i am using this example to read data from CRIO-9004.how i can datalog from this example. i need to save data for 100hz(sampling data)in the format of tdms or lvm. otherwise guide me for any example to datalog.

Hi maintenanace,

do you really want a "datalog" file or just a logfile of your data (which can be something completely different)?

LabVIEW comes with a huge library of example VIs, there are sure examples explaining how to use file functions…

hi there,

as crossrulez said, you have to have a mechanism of transferring data to your PC,

you have several options:

1. build your own TCP/UDP

2. Network Streams

3. Network Shared Variables

https://www.ni.com/docs/en-US/bundle/labview/page/data-communication-methods-in-labview.html

afterwards you can write the data to TDMS

  * https://www.ni.com/en/support/documentation/supplemental/06/the-ni-tdms-file-format.html

or .csv-/text-file

have a look in the examples coming with labview (search for TDMS or Network Streams)

with SSP you have online training which has two courses on RT

LabVIEW Real-Time 1

The LabVIEW Real-Time 1 course delivers hands-on training for prototyping deterministic measurement and control systems. At the end of the course, you will be able to design, develop, and prototype a real-time application that handles communication between the RT target and a host computer using NI recommended methods and LabVIEW Real-Time.

LabVIEW Real-Time 2

The LabVIEW Real-Time 2: Architecting Embedded Systems course delivers hands-on training for designing scalable, maintainable, and reliable embedded applications. At the end of the course, you will be able to translate your embedded system requirements into a scalable software architecture, choose appropriate methods for inter-process and network-based communication, design your real-time application for reliability, and efficiently deploy and replicate your real-time systems.

Hi GerdW

Thank you for your reply.

i need real data log from the crio
