Multiple PSP variables in one I/O Variable write?

[Jeff_A]

The setup:

1. Multiple 9146 eRIO chassis for a distributed I/O application

2. Each chassis has a 9477 DO module (32 DO's each)

3. LV App that accesses the 9146's via IP address using I/O Variables

Currently I am opening a socket to each DO line (single boolean), this is cumbersome and slow given that I have to send 32 transactions per 9477.

The Question:

Is there a better way to do this?  I've attached a snippet of code that attempts to access 8 DO's using a boolean array data type but that fails..

Thanks in advance for any help!

Hi,

 I think the other possible way will be to create a FPGA VI. With this you will be able to write to the entire port with a representation of an integer number.

Jeff, FPGA is the way forward man! Create an FPGA vi and read/write happily to your Host vi !!
