Iak file does not change channel config?

Question

I am relatively new to Lab-View so please bear with me
I have multiple iak files setup for different vi's that require some different ranges on the AI-100 modules I am using (FP-1601 Ethernet module). My problem is when I start a vi, with the iak file path needed wired to the FP-open tag, it does not change the channel configuration from whatever is currently on the modules themselves.
Is this correct? I know I can get the channels to update to the iak file by opening it in FP explorer and editing the device clicking on the channel config and syncing to the file. This will be very tedious for the un-trained test monkey these different programs are designed for. Am I missing some option somewhere that syncs the modules t
o the iak file when you open a field point session?

Answer 1

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.
