This integration requires the Mitsubishi Electric City Multi AC system be equipped with the Mitsubishi Electric G-50A, GB-50A o AG-150A gateway. This gateway from Mitsubishi Electric offers the signals of the City Multi AC system through XML protocol. Every G50 (G-50A, GB-50A o AG-150A) allows access to the signals of up to 50 City Multi internal units and 50 groups, no matter the number of external units installed. In the G50, the group is the control unit, every group can have from 1 to 16 associated internal units. This integration supervises and control groups, not internal units, although if only one internal unit is associated to every group then you can supervise and control internal units individually. This G50 gateway is supplied by Mitsubishi Electric. Contact your nearest Mitsubishi Electric distributor for details.
IntesisBox can talk to up to 2 Mitsubishi Electric G50s using XML protocol, and offers the signals of all these City Multi groups through its Modbus slave interface, each signal in a predefined fixed Modbus address. The Modbus interface of IntesisBox can be freely configured as RTU RS232, RTU RS485 or TCP. The commissioning of IntesisBox is almost plug & play, only IP parameters of the box and of G50s have to be configured using LinkBoxMB, a friendly software configuration tool for WindowsTM supplied along with IntesisBox with no additional cost.

IntesisBox Modbus Server - Mitsubishi Electric G50 Modbus interface
General Max. Number of Up to two G50s can be supported. Mitsubishi Elec.G50s Virtual signals One communication error virtual signal per every G50 device defined. One communication error virtual signal per every group into the G50 device. One virtual signal per every group into the G50 device to enable/disable this group in the polling process. All these virtual signals can be read/written from Modbus. Modbus interface Device type Slave. Modbus modes TCP, RTU RS232 or RS485. supported Modbus TCP IP address. configuration Subnet mask. parameters Default gateway address. TCP port. Modbus RTU RS232/RS485. configuration Baud rate. parameters Parity. Slave number. Points No point configuration needs to be done, all the Mitsubishi Electric G50 Configuration signals are automatically associated to predefined fixed Modbus Addresses. Modbus function Read functions: codes supported 3- Read holding registers. 4- Read input registers. Write functions: 6- Write single register. 16- Write multiple registers.
If poll records are used to read/write multiple records, the range of addresses requested must contain valid addresses, if not the corresponding Modbus error code will be responded.

Modbus data coding

All the point's values are coded in 2 bytes registers (even if their possible values are 0 and 1) and expressed in MSB.LSB.

There are also a series of signals that indicate an Alarm Code in any of the devices present in the M-Net Mitsubishi network. To obtain the Modbus address, you must apply following formula: ADRESS MODBUS = (20000+ (Numb.G50x1000)) + M-Net Add
where M-Net Add is 0 for the G50 device, 1 to 50 for Indoor Units, 51 to 100 for Outdoor Unit, 101 to 200 for Remote Controllers and 200 to 250 for System Controllers.
