IntesisTM INMBSPAN001I100 User’s Manual r1.2 EN 4. Modbus Interface Specification 4.1 Modbus physical layer INMBSPAN001I100 implements a Modbus RTU (Slave) interface, to be connected to an EIA-485 line. It performs 8N2 communication (8 data bits, no parity and 2 stop bit) with several available baud rates (2400 bps, 4800 bps, 9600 bps, 19200 bps, 38400 bps, 57600 bps, 76800 bps and 115200 bps). It also supports 8N1 communication (8 data bits, no parity and 1 stop bit). 4.

IntesisTM INMBSPAN001I100 • User’s Manual r1.2 EN AC unit external temperature reference (Modbus) (R/W) (register 22 – in Protocol address / register 23 – in PLC address): This register allows us to provide an external temperature reference from the Modbus side. Panasonic indoor unit does not allow on devices like INMBSPAN001I100 to provide directly temperature to be used as a reference of the control loop of the AC indoor unit.

IntesisTM INMBSPAN001I100 • User’s Manual r1.2 EN ▪ The mechanism of “Virtual Temperature” is applied. The temperature setpoint’s value shown by the Remote Controller or other Control System from Panasonic connected to the indoor unit may show a different value from the value shown in register 4/5. ▪ The User is not be able to change the setpoint using any Remote Controller from Panasonic, as setpoint of the indoor unit becomes exclusively controlled by the “Virtual Temperature” mechanism.
