Answered: TYPHOON HIL404 HARDWARE IS NOT ON

The LED should light up after you press the red power button at the back. Can you confirm that you're using a 12V 5A adapter? Maybe the adapter is faulty. Can you confirm the 12V at its output?

Sine Wave in VHIL but Mountain-shaped in C-HIL (TI C2000)

Mon, 04 May 2026 07:12:53 +0000

I am experiencing a strange discrepancy between my VHIL/HIL-to-HIL tests and my actual C-HIL setup.

My system overview:
- GFL inverter with LCL Filter (DC Link: 800V | Grid: 311 Vpeak).
- The plant (inverter and grid) built in Typhoon HIL simulator (HIL604)
- The controller programmed in TI C2000 MCU (Ti28069m) via PLECS Coder.
- PLECS Coder (MCU side) discretization is set to 1e-4. Typhoon HIL is set to "Auto" discretization.

I have successfully built and tested the complete control structure all the way to the outer loop (using power reference to generate the current reference). In this HIL-to-HIL environment, everything works great. Even when applying very high power references that cause some natural distortion, the grid current strictly maintains its sinusoidal shape.

When transitioning to the physical C-HIL, I rebuilt the system step-by-step.

The open-loop tests are perfectly fine (the TI MCU reads the ADC signals safely, and the PWM signals sent back to Typhoon HIL are correctly received).

However, the moment I close just the inner loop (current control), the system breaks. The grid current loses its sine shape entirely and becomes a mountain-shaped waveform.

Looking at the data, the output from the dq-to-abc transformation block shoots up to ~800V. Since the grid is 311V peak, the controller should ideally only demand around ~380V. This massive 800V request heavily saturates the PI controller and completely overmodulates the inverter. (I actually already tried manually scaling down this massive control output so it would safely fit into the PWM limits without overmodulating, but the resulting current still remained in that distorted, mountain-like shape.)

Are there specific execution/task synchronization settings between PLECS Coder and Typhoon HIL that I might have missed when transitioning from HIL-to-HIL to C-HIL? or any ideas on what this issue could be would be greatly appreciated!

Answered: Can I physically connect TI Launchpad with Typhoon Hil ?device and use them remotely?

Wed, 18 Feb 2026 08:14:54 +0000

Hi,

Physical connection between HIL and Launchpad can be done using HIL TI Launchpad interface.

Connection between PC and HIL device is done the same way regardless of which controller and interface you're using. You can access the HIL remotely if it's connected to the network via Ethernet.

I'd say that the main bottleneck you're facing is connection between the Launcphad and the PC. Having that in mind, the best setup would be a PC connected to the HIL and the Launchpad, which you can access remotely using Remote Desktop connection.

Answered: HIL 402 license is not valid

Wed, 28 Jan 2026 08:16:21 +0000

Hi Genis Joan Romano,

Let me try to help you here.
The license key which you received for HIL404 as per the second attached screenshot is invalid for real-time execution as it is just a virtual key(not meant for real-time, can only run simulation in software virtually).

However, the device license key for HIL402 which you have available is something different. You must contact the concerned person who has purchased the HIL402 device and they will share the hardware device key with you. Once you receive the key for HIL402 device, open Typhoon HIL software, go to the license option and at the bottom of the pop-up screen you can see change license option(attached picture 1- red block). Once you click there, you can insert the new alpha-numeric license key and restart the software.

After restart, you will be able to see HIL402 in the license window and then your hardware connection will be formed from device manager.

Regarding firmware, once the device is connected, just click on the sync firmware option on the device manager window and your firmware will be automatically synchronized with your current software version(attached picture 2- red block).

Hope this helps.

Answered: Typhoonheck HIL 604 and uGrid DSP Interface 2.1 Compatibility

Mon, 08 Sep 2025 08:50:36 +0000

Hello,

Both interface boards are compatible with HIL604. There are no any specific configuration steps required to use them with HIL604 device - just make sure the controller(s) are properly powered and programmed.

Answered: Support Request – Noisy ADC Results with Typhoon HIL 101 and TI F28379D

Fri, 29 Aug 2025 08:01:45 +0000

To follow up on Jovan's answer, I've attached a simple model where you can generate the code and validate ADC by using TI C2000 Toolbox. There is a subsystem called 'adc' where ADC component is configured and TI C2000 Setup component where you can click 'Build and deploy' button to generate and deploy the code to your controller. The value of the signal is scaled to PWM duty cycle range and applied to the input of the PWM component.

In order to observe ADC result, you can track the value of 'ao1_sample' probe in Code Composer Studio, or you can use the part of the model with PWM Analyzer which will output the duty cycle value of the PWM signal applied to the HIL digital input selected in the PWM component. This is an easy way to observe signals from external controller in SCADA. Keep in mind that you need appropriate HIL firmware configuration that supports PWM Analyzer according to device configuration table.

Answered: Problem with usb connectivity

Wed, 20 Aug 2025 11:32:18 +0000

Hello,

This might be a firmware issue with the HIL101. During the booting process of the HIL device the LED located at the front of the HIL should blink twice after some time.

Can you check if it is blinking twice on your HIl101? Keep in mind that the LED will first be turned on without blinking for a certain amount of time (around a minute) before you see the blinking.

If it is not blinking this could indicate a firmware issue.

Best regards.

Answered: Is there a way to remotely toggle power to the typhoon 606?

Thu, 03 Apr 2025 13:09:48 +0000

Hi Shivani,

Can you narrow down a bit more under which circumstances this happens? Is it only one device/model or are several units doing this? Is your HIL connected via USB or Ethernet?

You can rest the power remotely, but you need to be able to connect to the device. If you are not able to connect to it, Marko's suggestion is the way to go.

Answered: Is it possible to integrate Typhoon HIL code with an API?

Tue, 11 Feb 2025 13:45:16 +0000

Greetings Smriti,

Typhoon HIL provides a comprehensive API library that allows real-time data exchange and control. You can use Python-based scripting to interface with external data sources, such as a solar panel monitoring app, and feed this data into your HIL simulation. You can take a look at our API functions library on this link.

Hope this helps,

Answered: connection issues between the Typhoon HIL software and hardware

Tue, 19 Nov 2024 08:04:04 +0000

Greetings,

If you are connecting to your HIL device using USB, and in Device Manager you see that Connection status is NOT Connected, don't worry! You can learn more about what this means on this link.

If you are still experiencing issues with the USB connection during simulation or if it disconnects randomly, try connecting to a USB hub that has its own power supply.

I hope this helps!
