DAQFactory Express is a limited version of DAQFactory that is available for free! Like all versions of DAQFactory, it is the same DAQFactory program, just limited and free. To access DAQFactory Express, you can either click the Express button on the trial dialog:
or you can start Express from the shortcut created in the Windows Start menu. Once you open DAQFactory in Express you cannot switch to the trial or other version of DAQFactory without restarting DAQFactory.
Applications you create in Express will work in all the other versions of DAQFactory, so if you outgrow Express you can easily upgrade to a paid version of DAQFactory and continue your work. Note however, that while Express can open applications created with other versions of DAQFactory, it will trim the application down to fit within the limits of Express. This means that if you open a document with 14 channels in Express it will trim down the channels so only 8 remain. If you open a document that uses screen controls that aren't supported in Express, a box with an X through it will be drawn instead.
DAQFactory Express has a number of limitations including:
•Limited to 8 channels and 8 global variables
•Limited to 2 pages
•Limited number of available screen controls.
•No access to object oriented scripting
But even with those limitations, Express is great for doing basic data acquisition and control on simple applications and a great way to get started with DAQFactory.
