mbus A429 Receive Advanced.vi
Description
A429 Receive Advanced function receives incoming ARINC 429 data and offers advanced tools such as time tags and error detection.
All incoming data is checked against errors. The errorCount counter increments for each ARINC 429 word containing at least one error. The errors output contains detailed error report for each word in a429words. The mbus A429 Error Decompose decomposes the error output into individual errors and provides the number of errors decoded in each word.
