CT100 inverter Communication protocol
153
Interval time of 3.5 bytes
CMD (command instruction) and DATA
Command code: 03H, read N words (at most 16 words can be read)
For example: the baud rate 19200bps, even check (E, 8,1) for RTU, read
continuous two data from the inverter F06.19 with the slave address of 01.
Master command message
High bit of start address
06H (Function code group)
High bit of register number
Low bit of register number
Slave response message
Command code: 06H, write a word
For example: the baud rate 19200bps, even check (E, 8,1) for RTU, write
40.00Hz (communication without decimal point) (0FA0H) to F00.09H address of
the inverter whose slave address is 02H, and change the keypad set frequency
to 40.00Hz.
