Status Bar

This section describes the status bar

Figure 1: Status bar

The Status bar (Figure 1) consists of:

  • HIL SCADA Time Slot Overrun indicator - indicates that the HIL SCADA computation time exceeded the allocated time slot. When this flag is raised, it indicates that HIL SCADA cannot do all computations in the specified time slot either because of complexity of the embedded Expression scripts, the number of widgets in the particular time slot or because of interaction(s) with the rest of GUI while the simulation is running (using Capture/Scope, deleting and adding new widgets in HIL SCADA, etc.)
  • HIL SCADA Widget Errors indicator - indicates that error(s) occurred in some of the active Panel widgets
  • Signal Processing Exception indicator - indicates that an exception is thrown by the generated code running on either System, User or Communication CPU. The flag is reset when the simulation is stopped. If you click on the EXC flag, a floating panel (Figure 2) will open providing more detailed information about exceptions that have occurred.

  • Computing interval overrun indicator - indicates that the Signal Processing computation time exceeded the reserved time slot. The flag is reset when the simulation is stopped.
  • Serial link status indicator – indicates that the serial link with the HIL device is down. The flag is reset when the simulation is stopped.
  • Arithmetic overflow indicator - indicates that some values from the simulated model were out of the HIL device’s numerical range. This may be followed by erratic model behavior. The Arithmetic overflow flag is reset when the simulation is stopped.
  • Dead time violation indicator - indicates a shoot-through condition on any of the model's converter phase legs. If you click on the DTV flag, a floating panel (Figure 3) will open providing a list of all the latched DTV error sources. For more details about DTV detection logic details please refer to Typhoon HIL Schematic Editor Library (t-ug003).

  • PSU Fault indicator - Indicates status of the externally available power supply output. If you click on the PSU flag, a floating panel (Figure 4) will open providing more detailed information about power supply status.

  • Simulation elapsed time indicator
  • Start/Stop button - starts or stops the simulation in the Typhoon HIL hardware simulator. The Stop command will reset the state of the simulated model.
  • Simulation running indicator – in case the simulation is not running, it will show if offline or Virtual HIL mode is active.
Note: The state of some indicators, such as EXC, AO, DTV,can be reset manually at any time by selecting the Reset flag option available by right-clicking over the flag (Figure 5).
