Bit0 = 1 : Data sent to the driver via MODBUS communication will never be saved. Bit1 = 0 : Received data is returned upon receipt of a write command via MODBUS communication, and write is executed. Bit1 = 1 : Received data is not returned upon receipt of a write command via MODBUS communication, and write is executed. Parameter functions: P7-05 = 0 : If for communication, an address provided in the parameter list of this Manual is used, then the parameter will be written to the RAM register of the driver, and whether it will take immediate effect will depend on the parameter attribute; the parameter will not be saved upon power-off.
If for communication, an address provided in the parameter list of this Manual + 8000H is used, then the parameter will be written to EEPROM of the driver and immediately saved; whether it will take immediate effect will depend on the parameter attribute. P7-05 = 1 : If for communication, an address provided in the parameter list of this Manual + 8000H is used, then the parameter will be written to the RAM register of the driver, and whether it will take immediate effect will depend on the parameter attribute; the parameter will not be saved upon power-off.

Effect of P7-04 bit0 and P7-05 settings on the communication address and storage Parameter functions: Set the data high/low-position when the upper computer reads/writes a 32-bit function code. In actual applications, if a 16-bit function code reads/writes normally but a 32-bit function code reads/writes abnormally, this parameter needs to be changed. P7-09 = 0 : For both read and write, the low 16 bits are before the high 16 bits P7-09 = 1 :
For both read and write, the high 16 bits are before the low 16 bits P7-09 = 2 : For read, the low 16 bits are before the high 16 bits; for write, the high 16 bits are before the low 16 bits P7-09 = 3 : For read, the high 16 bits are before the low 16 bits; for write, the low 16 bits are before the high 16 bits Important:The sequence of high and low bits shall be set with reference to definition by the upper computer. The following shows a demonstration by reading a 32-bit function code P1-02 = 1234567 (in hexadecimal 0012 D687H). ● P7-09 = 0 (default value):The low 16 bits (D687H) are before the high 16 bits (0012H).
