Return data based on query requests
For example, to query about the circuit detection information about the inverter whose address is 01H,
the query and return strings are the same, and the format is described in the following tables.
RTU master command:
T1-T2-T3-T4 (transmission time of 3.5 bytes)
MSB of the sub-function code
LSB of the sub-function code
T1-T2-T3-T4 (transmission time of 3.5 bytes)
T1-T2-T3-T4 (transmission time of 3.5 bytes)
MSB of the sub-function code
LSB of the sub-function code
T1-T2-T3-T4 (transmission time of 3.5 bytes)
9.4.4 Command code 10H, continuous writing
The command code 10H is used by the master to write data to the inverter. The quantity of data to be
written is determined by "Data quantity", and a maximum of 16 pieces of data can be written.
For example, to write 5000 (1388H) and 50 (0032H) respectively to 0004H and 0005H of the inverter
whose slave address is 02H, the structure of the frame is described in the following table.
RTU master command (transmitted by the master to the inverter):
T1-T2-T3-T4 (transmission time of 3.5 bytes)
MSB of data writing address
LSB of data writing address
