Solution
Please note the following behaviours of parameters on a VeriStand screen:
- Parameters displayed on a VeriStand screen only update when the user changes the value from VeriStand (whether that is manually or through automation).
- Changes to parameter values from within the model are not read back out into Veristand until the screen controls are modified as above.
If you witness this behaviour:
- Verify your model is in the Running state using the Model Status channel. The value will be 0. Refer to the VeriStand help for details on other values.
- You can attempt a reset of your model by changing the Model Command channel to 2. The values are documented here.
- Monitor some signals within your model to determine the model is running as expected.
If the model is not running, recovering after a reset and/or not updating signals, debug your model code.
Refer to
Common Issues with Models in VeriStand and if you have LabWindows/CVI, refer to
the debug section here.
If the model is running as expected and signal values are updating correctly, use the following to view parameter values updating during model runtime.
- Monitor a signal that already uses the parameter value.
- Create a new signal in the model and map the desired parameter to this signal within the model.
. Signals will show the values as the model runs and give you the up to date value on a VeriStand screen.
