This industrial WiFi controller, the Norvi Agent 1 – BM01 series, supports analog and digital inputs as well as interfacing with RS485 bus peripherals. They can be bought directly from the manufacturer, Iconic Devices, and resellers sell similar variants. Learn to setup it up manually below.
Interfaces of the BM01 #
- 3 digital inputs
- 2 analog inputs (WIP)
- 1 RS485 interface (WIP)
- Button
- RGB LED (WIP)
- Mini-USB
- 24V power input
Firmware for Norvi Agent 1 Devices #
The mainline ima_esp32 and ima_esp32_dbg firmware variants support this device. Use the Inamata Flasher app to flash the latest version (from 0.11.0) to connect it with the server. Currently only the relay output is fully supported. The remaining peripherals have backend support while the frontend support is still being worked on.
Manual Device Setup #
RS485 Interface #
Status: Backend WIP, frontend WIP
The RS485 interface allows sending and receiving messages to and from other RS485 devices. Internally the Texas Instruments MAX485 is used. Setting it up first requires creating a UART adapter peripheral and then the MAX485 adapter peripheral.
Analog Inputs #
Status: Backend support, frontend WIP
The analog inputs allow a voltages to be measured on 3 different channels. Internally the Texas Instruments ADS1115 sensor is used. Setting it up first requires creating an I2C adapter peripheral and an ADS1115 adapter peripheral. Then, one ADS1115 input peripheral has to be added for each channel. All ADS1115 input peripherals share the ADS1115 adapter peripheral.
Add an I2C adapter peripheral and select pin 21 for the data (SDA) port and pin 22 for the clock (SCL) port. After confirming that the peripheral has been successfully added, add an ADS1x15 adapter peripheral. Select the I2C adapter that was added in the previous step and set the I2C address to 72 (0x48). As the variant select ADS1115. After confirming this peripheral was added successfully as well, add an ADS1x15 input peripheral. Select the added ADS1x15 adapter and then the appropriate channel. Channels 1 to 2 map to ports A0 to A2 on the bottom right of the controller. Set the gain to 1x for a range of 0 to 10 V. Then select the data point type that corresponds to the connected sensor. Finally select voltage or convert to unit and which mirror the analog input peripheral setup.
Button #
Status: Full support
The button located on the left face of the controller allows a user to send a signal. To use it add a digital input peripheral to the set up controller with the following configuration.
Select pin 35 as well as a data point type the corresponds to the button. Set the input type to floating and enable active low as 1 is returned when the voltage is high.
Digital Inputs #
Status: Full support
Select pin 18 for channel 1, pin 26 for channel 2 and pin 27 for channel 3. Select a data point type the corresponds to the connected sensor. Set the input type to floating and enable active low as 1 is returned when the voltage is high. The respective internal LED will turn on when the voltage goes high.
RGB LED #
Status: Backend support, frontend WIP
The RGB LED allows a status with different colors to be displayed. Internally an WS2812 NeoPixel is used.
Select pin 25, an LED count of 1 and the color coding grb. The color or brightness of the LED can be set with an SetRGBLED task.
