Modbus Gateway

Tosot Modbus gateways for the central air conditioning system are used to bridge the internal network of the air conditioning system (CANbus) and the monitoring network (Modbus). It will provide the web-based remote monitoring and control system/BMS communication interfaces and is enabled to take the real-time monitoring and the long-distance control to the air conditioning system. Also, it will provide the Modbus RTU protocol, five digital inputs and five digital outputs, among which the DI1 is defined for the fire alarm input (when the fire alarm signal is input, the Modbus gateway will stop the air conditioning system immediately).

CAN Interface: It is connected to the air conditioning system through twisted pairs so as to get through the communication between the Modbus gateway and the air conditioning system.
RS485-1 Interface: It is connected to the Web-based Remote Monitoring and Control System/BMS through twisted pairs so as to get through the communication between the Modbus gateway and the Web-based Remote Monitoring and Control System/BMS.
RS485-2 Interface: it is reserved.
