Select Points to Display in Simulation Log Window

To be able to simulate function blocks, they must be linked to other function blocks or output points or configured as Out_Save, Out_Byte, Out_float, or constant. An exception, however, is the Alarm function block. If you have an Alarm function block with only its input linked, you can still perform simulation.

To be able to simulate input points (NVIs, NCIs, Network Inputs, Network Setpoints, analog inputs, and binary inputs), they must be linked to function blocks or other output points.

To select the points being simulated that need to be visible in the Watch Window:

  1. Click the SelectPt button on the tool bar to select points. The Select Points to be displayed in the Simulation Log Window dialog box appears. The following table defines the fields shown in the dialog box.
Name Definition
Select Function Block Shows all the Function Blocks, Physical I\O's and Network Variables (NVIs/Network Inputs, NCIs/Network Setpoints, Software Inputs and points that are not constants, physical inputs such as analog and digital inputs) that have output points and are connected to other functional blocks or network variables.
Select Output Points Shows all the output points of selected Function Blocks, Physical I\O's or Network Variables (NVIs, NCIs, Software Inputs that are not constants), or Objects (Network Inputs, Network Setpoints, Software points that are not constants) that are connected to other functional blocks or network variables or objects.
Select point path Indicates the location of the component. It is a relative and not an absolute path
Select point ord Indicates the absolute path. It can be used to resolve the component.
Point Name Shows the points selected to be displayed in the watch window.
OK Saves the selected points to be debugged and closes the dialog box.
Cancel Closes the dialog box. Any operation done so far is cancelled.
  1. Select the Function Block or Network Variable or Bacnet Objects from the Select Function Block section. The output points are shown in the Select Output Points section.
  2. Select the output points that you want to view. The selected points appear in the Point Name section.
  3. Click OK. The points appear in the watch window with the values.

View Values in Watch Window

After you have selected points to be displayed in the Simulation Log Window, the points appear in a Watch Window at the bottom of the wiresheet. Use this to analyze your application logic and to find the values being returned based on the logic you have defined.

Note: All points in the logic is simulated. However, only those points which are selected to be viewed in the Watch Window are displayed in the watch window.

View Values without the Watch Window

The output values of each point in the logic can also be viewed without the watch window. The values are displayed at the output pin of each point.

To close the watch window:

Changes in Select Points Screen On Changing Modes

After you have selected the points to be debugged, if you switch to another mode and select or deselect the points to be debugged and then get back to the Online Debugging Mode, the selected points are not selected to be displayed in the watch window. You have to select them again.

  1. If you select a point for debugging & enable the watch window option in Engineering or Debugging mode, it is retained in Simulation mode.
  2. If you select a point for debugging and uncheck the watch window option in Engineering or Debugging mode, the same is not retained in Simulation mode.
  3. If you select a point in Simulation mode, it is retained in Engineering or Debugging mode with the watch window enabled.
  4. Select a point for debugging and with the watch window option unchecked in Engineering or Debugging mode. If you select the same point in Simulation mode, then on returning to the Engineering or Online Debugging mode, this point is found to be with the watch window option enabled.
  5. If you add and remove a point in Simulation mode, the same point is selected for debugging but not for watching in the Engineering or Online Debugging mode.
  6. Select a point in Simulation mode. Go to the Engineering or Debugging mode and see that it is selected for both Debug & watching. Now, uncheck the watch window option. You find that it is not shown in Simulation mode.

Note:

The value written to a point and the mode last set (in Engineering, Online debugging, or Simulation) is available the next time you visit any other mode (Engineering, Online debugging, or Simulation) with the following exceptions:
