(2) Function explanation
Word data of continuous word number is written from write-in start address. Write-in word data are
transmitted from master station in the order of upper and lower bytes.
If write-in data does not fall within the effective range, response is made without counting it as write-in word
number. If an attempt is made to write data in an unused address, write-in is not performed, and response is
made without counting it as write-in word number.
