I'm trying to write a LabVIEW interface to communicate with Fieldbus devices. I have figured out how to navigate down the chain of interfaces to devices to blocks to whatever else is between me and the data I'm trying to get and now that I can read the parameters, I want to be able to write them. I took my best guess, but when I call the FF write block object (by name), the vi generates some internal error for which there is no description. I've attached a picture of the code. Anyone know what I'm missing?
Solved! Go to Solution.

Hi,
You should use the FF Encode.vi to convert data instead of the String to Byte Array.vi.
Thanks!

The code is fine. The problem is the MODE_BLK setting has to have a bit toggled for the device to accept changes.

Have to set the mode block to allow writing.

Nested stacked sequence structures? If a developer wanted to murder you, I'd hand him a stapler. That would guarantee a painful death. 😉
