Problem: Are there any known issues with Control Design and Simulation Module 8.5? Solution: The following is a list of known issues for the Control Design and Simulation Module 8.5. See the readme for other known issues. Installation order of LabVIEW, Control Design and Simulation Module and related productsAs with all toolkits and modules, the version of LabVIEW to which you are installing the toolkit or module must be installed first. In the case of the products mentioned below, the Control Design and Simulation Module 8.5 must be installed after any previous versions of Control Design Toolkit, System Identification Toolkit and/or Simulation Module.You must install these products in the following order:
Missing error code descriptionsThe error code file that ships with the Control Design and Simulation Module 8.5 is incomplete see KnowledgeBase 4BQB2E7G: Missing Error Code Descriptions for Control Design & Simulation Module 8.5 for more details.Rosenbrock and BDF solver accuracy on LabVIEW Embedded targetsComputational accuracy of Rosenbrock and BDF solvers is not assured on LabVIEW Embedded targets. See KnowledgeBase 4BNDLR00: Rosenbrock and BDF Solvers Produce Incorrect Results on the ADI Blackfin for more details.Discrete Transfer Function with SIM and CDT Datatype Have Different ResultsSubstitute the existing LLB in C:\Program Files\National Instruments\LabVIEW 8.5\vi.lib\Simulation\DiscreteLinear\Implementation\SIM Discrete Transfer Function Direct.llb with the one attached and mass compile the VI's running in LabVIEW.Alternatively you can open the VI from C:\Program Files\National Instruments\LabVIEW 8.5\vi.lib\Simulation\DiscreteLinear\Implementation\SIM Discrete Transfer Function Direct.llb\SIM Discrete Transfer Function Diagram (SISO CD).vi and manually modify the terminals from State Derivatives (input and output) to States (input and output) as shown in the image below.
