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. | The red LED inside the device glows. Display turns on. |
| Digital Inputs | Power up the device using a 24V DC supply. Connect the device to the PC using a USB cable, and check the serial monitor. Connect the GND and COM pins and supply 24 VDC to every digital input one by one. | In the input status, the status of all eight digital inputs will be 1.(As they are internally pulled up) The input status changes from 1 to 0, and the input side LED indicator starts to glow accordingly. |
| Voltage Input | Power up the device using a 24V DC supply. After powering up the device, to check the working of the analog (voltage) input, supply a voltage between 0 and 10 V (10 V mqx) to the voltage input. Check this link for the wire connections. | A corresponding analog voltage step value is displayed. |
| Push Buttons | Press the 3 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 is printed. This indicates that the RS-485 sending operation is functioning properly in the Norvi device. Once the number “5” is received, all the output side LED 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 receiving operation is functioning properly on the Norvi device. |
