Error-2628. LabVIEW: (Hex 0xFFFFF5BC) An error occurred while parsing the document in FPGA Compilation

Issue Details

In cRIO FPGA programming mode, I opened the NI 9467 Datalogging.lvproj example of the NI 9467 module shown in the figure below, and directly compiled the FPGA VI file.

The following error occurred during the final stage of compilation when generating the programming file.

LabVIEW: (Hex 0xFFFFF5BC) An error occurred while parsing the document 

Error-2628 occurred at Inovke Node in XXXX

Possible reason(s):

LabVIEW: (Hex 0xFFFFF5BC) An error occurred while parsing the document 

What is the reason?

Solution

Check if the extended ASCII characters in the text throughout the FPGA VI are displayed correctly. In the FPGA VI of the NI 9467 Datalogging.lvproj example, under normal circumstances (as shown in the image below), extended ASCII characters such as "°" should be displayed correctly, and the VI should compile successfully.

However, on another computer (as shown in the figure below), the "°" in two of the property nodes of the same FPGA VI is not displayed correctly, and the "°" in the labels of  indicators these two properties are connected to is also not displayed correctly as well. This problem will be encountered when compiling this VI.

Solution:

1. If you don't need the relevant attribute, you can remove it by right-clicking on the item and selecting "Delete Element." Please also delete any controls whose names are not displaying correctly.
2. If you need to use this control, please try to make extended ASCII characters display correctly by following the steps in the article Display Unicode Language Characters in LabVIEW on Windows.

Additional Information

The problem discussed in this article was encountered when compiling the NI 9467 module example, but the problem may also exist in other FPGA VIs.
