Convert a downloaded and operational MPCPro application to an MPCPlus application

  1. Place the MPCPro block in MAN mode or shed all MVs to Local mode.
  2. Open the module with the MPCPro block in Control Studio.
  3. Select the MCPro block and click Convert To Existing Object.
  4. Browse to the MPCPlus block in the Advanced Control Function Block Templates and click OK.
    The MPCPro block changes to an MPCPlus block.
  5. Save and download the module with the MPCPlus block.
  6. Open the Tuning dialog in the MPC Operate Pro application and check the Optimizer settings.
    For loops in which the SP Range was used to maintain the CV within constraints with an MPCPro block, the optimization type with an MPCPlus block may need to change from Target to None with specified SP Hi and Lo limits. Check the Penalty on Moves and Penalty on Error values.
  7. Observe the prediction vector in MPC Operate Pro. If the vector is a flat line continuation of the current process value, it should be initialized by setting the FOLLOW parameter on the MPCPlus block to 1. Wait until the prediction flattens before returning FOLLOW to 0.
  8. Upload the changes to the database.
  9. Place the MPCPlus block in AUTO and confirm that the application works as expected.
