Summary:

The maximum span of data that can be successfully retrieved by a TrnExport function has unintentionally been greatly reduced. The times and received sample values will be incorrect if the period times the length of a TrnExport function request is greater than approximately 25 days.

Solution:

CIT has confirmed this to be a problem in Citect for Windows versions 5.31 to 5.40. This problem has been fixed in version 5.41.
