10.4.3 Command code 08H for diagnosis
Meaning of sub-function codes
Return to inquire information data
For example: The inquiry information string is same as the response information string when the loop
detection to address 01H of driver is carried out.
The RTU request command is:
T1-T2-T3-T4 (transmission time of 3.5 bytes)
High bit of sub-function code
Low bit of sub-function code
T1-T2-T3-T4 (transmission time of 3.5 bytes)
The RTU response command is:
T1-T2-T3-T4 (transmission time of 3.5 bytes)
High bit of sub-function code
Low bit of sub-function code
T1-T2-T3-T4 (transmission time of 3.5 bytes)
10.4.4 Command code: 10H, continuous writing
Command code 10H means that if the master writes data to the inverter, the data number depends on
the "data number" in the command code. The maximum continuous reading number is 16.
For example, write 5000(1388H) to 0004H of the inverter whose slave address is 02H and 50 (0032H)
to 0005H, the frame structure is as below:
The RTU request command is:
