Index to NI 9802 port access

[Manzolli]

The NI 9802 (Secure Digital Removable Storage Module for CompactRIO) is a cRIO module that has two SD memory card slots. The problem is that the programmer cannot index the ports as "0" and "1". The solution is to write a code for "0" and repeat it for "1".

The proposal is to allow the user to select memory card by a terminal in the "Method" and "Property" nodes.

Since the maximum amount of memory per card is 2 GB, if more than 2 GB is needed, the programmer should manage to split the data in two cards. Right now the code should be duplicated and selected by a "Case" structure. In many other situations the programmer may need to use one or other card, like when a big file should be saved after the usual check of the available free space in both cards.
