Configuring the Base Unit’s Registers
Multiple simple registers are used to configure the base unit.
Most of these configurations will be done using the configuration interface. However, it is possible only to use Modbus to configure the unit.
The parameters in this register are read/write and can be modified by writing to them during the initial configuration process. Once this configuration is operational, it will be stored in the device’s non-volatile memory and become the device’s default configuration
This register data is represented as a 16-bit unsigned integer.
The Sensorbee Modbus’s Default Configuration Parameters
The following table describes the Sensorbee Modbus’s default configuration parameters with their value ranges.
Parameter | Address | Address (Hex) | Value | Version |
Slave Address | 0 | 0x0000 | Value range: 1 to 247
Default: 1. | ≥ 1.0.0 |
Baud rate | 8 | 0x0008 | Value range:
1. 9600
2. 115200
3. 192000
4. 576000
Default: 9600. | ≥ 1.0.0 |
Parity | 38 | 0x0026 | Value range:
0: None
1: Odd
2: Even
Default: 0 | ≥ 2.0.0 |
Stop Bits | 39 | 0x0027 | Value range:
1: 1 stop bit
2: 2 stop bits
Default: 2 | ≥ 2.0.0 |
While the register can accept any 32-bit value, the Modbus protocol only accepts specific values. As a result, it is crucial to be mindful of the possibility of configuring an invalid value.
The Sensorbee Modbus’s Measurement Register
The Sensorbee Modbus unit stores its sensor measurement values in the Modbus input register.
See the following register map for details on the data we collect from the sensors attached to the unit
