Issue 350189 and 379680:
Real-time sequence expressions may produce incorrect results if they have the same variable on both the left-hand side and the right-hand side of the equation, and the right-hand side of the equation also contains other compound operations.
For Example: x = x + sin(y * 100). This example may apply the result of sin(y * 100) to the variable x before it is added to sin(y * 100), causing the result of the expression to be 2 * sin(y * 100).
Real-time sequence expressions might produce incorrect results if they have nested sub-sequences in a single expression.
For Example: x = subsequence1(subsequence2(y)) . This expression, where subsequence 1 and subsequence2 are both real-time sequences, can result in an incorrect result for x.
This behavior can cause incorrect results in real-time sequences. NI recommends that every VeriStand 2011 and Veristand 2011 SP1 user apply the VeriStand 2011 f1 and VeriStand 2011 SP1 f1 patch respectively.
To test if a real-time sequence is affected by this issue Real-Time Sequence Checker Tool to test your real-time sequences. If any sequences are affected contact NI to determine the effect of the described issue on the results of the sequence.
