    MODBUS communication. 9.4 Protocol Description KE300 series inverter communication protocol is a kind of asynchronous serial master-slave communication protocol. In the network, only one equipment (master) can build a protocol (Named as “Inquiry/Command”). Other equipments (slave) response “Inquiry/Command” of master only by providing the data, or doing the action according to the master’s “Inquiry/Command”.

    MODBUS Communication Protocol 9.5 Communication Data Structure MODBUS protocol communication data format of KE300 series inverter is shown as following: In RTU mode, the Modbus minimum idle time between frames should be no less than 3.5 bytes. The checksum adopts CRC-16 method. All data except checksum itself sent will be counted into the calculation.
