How do I change the DAC service serial port assignment in a distributed applications

[Stebo222]

I am in the process of writing an application for end of line testing of large commercial HVAC units. It is our intention that this will be a distributed application on several workstations.

I am successful setting up a modbus serial connection to the hardware we are using when in the development system but once the application is built and installed onto another PC, no data is passed from the NI variable Engine to the shared Variables in the VI. The comm port is identical and the port settings should get handled through the executable application I would assume.

Does anybody have any clues?

One more detail... I'm using the development version of DAC until my purchase gets approved. Does this have any bearing on the issue???

Hi, do you see the variables at the Distributed System Manager? If not, I believe you need to check this article. Something to keep in mind is the path for the library, it changes once it's built into an executable so make sure you are pointing to the right direction (a regular fix is striping the path, it may not work on the VI but it will on the .exe).
