Software DAQ question

[vepa]

I wanted to find out if

1) all the DAQs write to an output file continuously?

2) how can we have access to read the file where data is being written to, programmatically through Java or python? Is there only a particular type/brand of DAQ software that allows for this?

3) can you DAQ software work on the cloud i.e. logging to a web interface?

1. Read the specs and check the settings.
2. Read the specs...
3. Read the specs...

What exactly do you want to achieve? Which "DAQs" are we talking about?

I believe the OP is asking about the features of a DAQ application software for data acquisition.

Typically, NI DAQs come with a set of device drivers for various programming languages that you can use to develop "your own" custom data acquisition software and hence the feature set are dependent on how you implement stuff.

You could also purchase one of the off-the-shelf data acquisition software such as FlexLogger or DAQ Express that satisfies the most common data acquisition tasks.
