From a program perspective, the IAK file is solely used to provide channel mapping information. From a FieldPoint Explorer (or NI-FP) perspective, the IAK file contains all channel naming information, communication mapping information and channel configuration information. In FieldPoint Explorer (3.0.2 or less), the only way to change the channel configuration between IAK's, is to switch IAK's in FP Explorer and right click on each (and every) FieldPoint IO Module, choosed Edit This Device and then choose Channel Configuration. When the dialog box asks you whether to use the Device or File settings, choose File. In NI-FP 4.0, there exists an option to download the entire configuration to an entire bank at a time, but there is still no method of downloading the co
nfiguration file programmaticly at run time.
However, another option in the form of the Ethernet Configuration VI's exists. They allow you to programmatically configure each channel (range & attributes). For an understanding of the range and attribute values, you can cross reference the FP-1000/1001 Programmers Reference Manual.
