Page 17: Modbus Interface Specification
INMBSDAI001I000 Modbus RTU Gateway Modbus Interface Specification 5. Modbus Interface Specification 5.1. Modbus Physical Layer The INMBSDAI001I000 gateway implements a Modbus RTU (server) interface to be connected to an EIA-485 bus. It features 8-N-2 communication (eight data bits, no parity, and two stop bits) with several baud rates available (2400 bps, 4800 bps, 9600 bps -default-, 19200 bps, 38400 bps, 57600 bps, 76800 bps, and 115200 bps). - Page 18 Modbus Registers INMBSDAI001I000 Modbus RTU Gateway Register Address Register Address Description (protocol address) (PLC address) 1,2,3 AC unit Temperature Setpoint -32768 (initialization value) COOL 18 .. 32°C 64 .. 90°F HEAT R, W 16 .. 30°C 61 .. 86°F AUTO 18 ..

Page 20: Considerations On Temperature Registers
Modbus Registers INMBSDAI001I000 Modbus RTU Gateway 5.2.3. Considerations on Temperature Registers • AC unit temperature setpoint (R/W) (protocol address register 4 / PLC address register 5) This is the adjustable temperature setpoint value required by the user. This value can be read and written. A remote controller connected to the Daikin indoor unit will report the same temperature setpoint value as this register. -
Page 21: Implemented Modbus Functions
INMBSDAI001I000 Modbus RTU Gateway Implemented Modbus Functions When the gateway detects a change of any of the values of {S , or T }, it will send the new setpoint ) to the indoor unit. After a device boot, the value for the external temperature reference (register 22/23) is -32768 (0x8000). This value means that no external temperature reference has yet been provided to the object, so the system is not applying the virtual temperature function. -
Page 22: Termination Resistors And Fail-Safe Biasing Mechanism
Termination resistors and Fail-safe Biasing Mechanism INMBSDAI001I000 Modbus RTU Gateway 5.4. Termination resistors and Fail-safe Biasing Mechanism IMPORTANT The EIA-485 bus requires a 120 Ω termination resistor at each end to avoid signal reflections. In order to prevent fail status detections by bus receivers when all the transmitters' outputs are in a high- impedance state, a fail-safe biasing mechanism is required. -
