Introduction #
- This guide is intended to test the features and basic operation of the device, the NORVI IIOT-AE02-V (voltage model).
NORVI IIOT-AE02-V test program.
Table of Test Instructions
Flash the test code firmware before testing the device. Follow the instructions given in the Guide to Flashing the Test Code Firmware guide to flash the binary code.
| Testing component/feature | Test | Expected Output/Outputs |
| Power | Provide a 24V DC supply. | A red LED inside the device glows. Display turns on. |
| Display | Power up the device using a USB cable or a 24V DC supply. | The display starts with the Norvi logo. The device model is displayed. A final screen with Input, output, and Push Button status appears. The output-side LED indicators glow in a pattern. |
| Digital Inputs | Power up the device using a 24V DC supply. Connect the GND and COM pins and supply the 24V DC to every digital input one by one. | Refer to the expected outputs of the Display Check above. In the input status, the status of all eight digital inputs will be 1.(As the inputs are internally pulled up.) The input status changes from 1 to 0, and the input side LED indicator starts to glow accordingly. |
| Voltage Inputs and Transistor Outputs | Power-up the device using a 24V DC supply. | The status of all six analog inputs will be 0. Toggling output status (from 0 to 1 ) is observed on the display for the 2 transistor outputs, which follows the output side LED indicator blinking pattern.Whenever these LEDs are on, it means the respective transistor is on. |
| Voltage Inputs and Transistor Outputs (continued) | After powering up the device, to check the working of the 6 analog (voltage) inputs, supply a voltage between 0 and 10 volts (10 volts max) to each voltage input. (Check this link for the wire connection.) To check the working of the two transistors, a voltage test is done using a multimeter.To do this, keep the positive probe of the multimeter on the +24V pin of the device. Next, touch the negative probe with the two transistor output pins, one by one after a 15-second gap. | On the display, the voltage sensed by the Norvi device is displayed.(You can confirm these voltage values using a multimeter.) The multimeter shows a 24 V DC reading, whenever the transistor is on.(Transistor status is indicated by the respective output side LED indicator and the output status on the display.) |
| Push Buttons | Press the three push buttons, one at a time. | The 4-digit analog status of the push button is displayed accordingly on the display. Analog status 1_ _ _ for the upper button Analog status 2_ _ _ for the middle button Analog status 3_ _ _ for the lower button |
| RS-485 Communication | For this test, a USB-to-RS-485 converter is required. Connect the RS-485 A and B pins of the Norvi device with the respective A and B pins of the USB to RS-485 converter. Plug the USB end of the USB-to-RS-485 converter into the PC. Power up the Norvi device using a USB Cable. Open the Arduino IDE application. Select the correct COM port of the USB to RS-485 converter in the Arduino IDE and open the serial Monitor. Send the Number ‘5’ in the serial monitor. | In the serial monitor, the “RS485 SUCCESS” statement getting printed is observed. This indicates that the RS-485’s Tx operation is working properly in the Norvi device. Once number “5” is received, all the output-side LEDs indicators will glow simultaneously for a few seconds. Then later they’ll continue to glow in their previous pattern. This indicates that the RS-485’s RX operation is working properly in the Norvi device. |
