Setpoint Range and Error with Beta Calculation Incorrect on PID Advanced.vi

Primary Software: LabVIEW Toolkits>>PID Control Toolkit
Primary Software Version: 6.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
Why does the PID Advanced VI only affect the output if the beta parameter is used?

Solution:
The PID Advanced VI that ships with the PID Toolkit contains two errors.

1. The cluster order for the setpoint range cluster is inconsistent
2. The PID Get Error VI has swapped the error and error with beta

To fix the problem you will need to replace both the PID Get Error VI and the PID Advanced Integral Action VI. Unzip the attached file and replace the files on your computer with these new ones. Both of these files that need to be replaced are located in PID.llb (Normally located in)
labview X.X\vi.lib\addons\control\pid\pid.lib

To replace these files, open LabVIEW and go to Tools»VI Library Manager. Navigate the left window to the unzipped VIs. Navigate the right window to the PID.llb file. Delete the file (inside the .llb file) on the right. Now, highlight the proper file on the left and then click copy.
