Getting address errors when trying to access Wago 750 PLC modules

$

Hello all.  First off, I know there are many topics dealing with this kind of issue, but the problem is that links that are given in those topics always come back with a 404 Not Found, so I can't follow what suggestions people have given because I can't get to the pages they link.

 

So I have a Wago 750-8101 controller with the following modules attached:

 

750-458 - Thermocouple module

750-1407 - 24V input module

750-1504 - 24V output module

 

I am trying to use Labview Modbus to read the modules.  For my immediate need, I am trying to read the 458 thermocouple module.  Attached is the program I am using.  The pictures show the error I get as well as the plc addresses for the modules

 

I have done some other research, and seemed to recall something about using Network Shared Variables to access the modules.

 

Why am I getting the error when I am using the addresses the plc is giving?
