- #### Handling parameter mismatches A parameter mismatch occurs when a value in a controller does not match the value in the WebCTRL Server application. This can be a driver or control program value. Use either of the following methods to handle mismatches in your system. Method 1: Check Always resolve parameters on mismatch on the System Settings > Communications tab to have the WebCTRL® application automatically upload if a value was changed in the controller or automatically download if a value was changed in the WebCTRL® interface. Method 2: Uncheck Always resolve parameters on mismatch so that you can evaluate a mismatch to determine the correct value. To find mismatches in your system If your system uses Method 2, you can find mismatches in the following places: The Devices page > Manage tab > Status column will show Parameter Mismatch. The Properties page for a controller, driver, control program, or point will show one of the following red messages at the top of the page stating: Control Program parameter differences detected. Driver parameter differences detected. Parameter download required. The value that has a discrepancy will appear with a purple box around it. Hover your cursor over the field to see:
  | or |
Go to Reports > Equipment > Parameter Mismatch, and then click Run to get a report of any existing mismatches in your system. NOTE The Downloads page > Tasks column will show Resolve Parameters for any mismatches that your system discovered in the 3 places listed above. To resolve a mismatch Go to one of the following: Devices page - Click the Parameter Mismatch link Properties page that shows one of the red messages above Click one of the following: Resolve to let the WebCTRL® application download changes made in the WebCTRL® interface or upload changes made in the controller. Click the Details button to see what the discrepancy is and whether Resolve will download or upload parameters. See NOTE below. Upload to upload the parameters from the controller to the WebCTRL® application Download to download the parameters from the WebCTRL® application to the controller NOTE On the Devices page with Show Control Programs unchecked, if a controller has simultaneous mismatches in the driver and control program, clicking Details will show that a control program mismatch exists but it will only show details for the driver mismatch. You must go to the control program in the tree to see details of that mismatch. However, clicking Resolve will resolve both mismatches.
