Hardware Installation
Detailed instructions and wiring diagrams for the boneIO controller, including power, inputs, outputs, and communication buses.
Modbus RS485
Used for communication with industrial and HVAC devices.
- Connect the
Aline of the bus to theAterminal on the boneIO. - Connect the
Bline of the bus to theBterminal on the boneIO.
ESP series devices have undergone Modbus RTU bus testing with 5 connected devices. Using a larger number of Modbus devices connected to an ESP series controller may cause delays in the controller's response (both inputs and outputs). This is due to the specifics of the processor used. In the case of extensive Modbus buses, we recommend splitting them across several devices.
