OMUDClass.cpp using Modbus communication

[ChristianLiinHansen]

Hi there. 

I dont know how, but now my labview code is giving me this error. 

Basically any ideas? 🙂 

When I click "Investigate now" it generates a error-log, with this informations:

It is regarding using two many processors? 🙂

DWarns aren't something to necessarily be concerned about (I think you can go into Tools>Options>Environment to simply ignore this prompt).

When do you receive this error (I'm guessing it's either on LabVIEW open or close)? If I remember correctly, OMUDClass generally deals with loading LabVIEW classes so you may want to try mass compiling the Modbus library source files to start.

I get the error when I starting up Labview, yes 🙂 
How to "mass compiling"? 🙂

Tools > Advanced > Mass Compile. You'll need to select a folder which will probably be either "<LabVIEW>\vi.lib\Modbus" or "<LabVIEW>\vi.lib\NI\Modbus Library".
