*1)Address

Set the address for sending information

*2)Function code

*3)Start address

Set as the start address for the register that needs to be written

*4) Number of registers

Sets the number of registers written. The maximum number is 12.

*5) Number of data

Setting range is 2~24. Set 2 times the value specified in *4).

*6) Write data

Set data division specified in *4). Write data is set in the order of high byte to low byte. Setting is

performed in the order of starting address data, starting address +1 data, starting address +2 data ...

4. Function diagnosis (H08)

In order to send the query information, the query information (function of subfunction code H00) is returned as it is,

and communication check can be performed.

*4)Data

The data can be set arbitrarily if the length is 2 byte. Set range is H0000~HFFFF.

5. Error response

If error is contained in the function/address/data received from the device, do function diagnosis;

However, when using function code H03 or H10 to access more than one address, if one or more data can still

operate, it will not be seen as an error.
