Instruction Execution Chapter 6
This implementation affects UDTs that contain LINT data types, including
LINTs that are in nested UDTs.
Mitigation
See Produce and Consume Tags on page 96, if you Produce/Consume tags in
UDTs between the following:
• 5580 and 5570 controllers that use Logix Designer projects, version 26
or earlier
• 5380 and 5370 controllers that use Logix Designer projects, version 26
or earlier
For more information about mapping, see Data Structures on page 97
.
If you use COP or CPS instructions to move data between UDT-based tags
and simple arrays, review your logic. Make sure that the COP/CPS
instructions are the correct length, and the logic matches the position of the
data within the array.
For example, when you use a CPS instruction to copy a SINT[32] array that is
obtained from an external device into a UDT that contains LINTs
