Parameters Write Data (Command)
Specify in order the contents of the number of words to be written to the IR or SR
area in hexadecimal, starting with the specified beginning word.
Note If data is specified for writing which exceeds the allowable range, an error will be
generated and the writing operation will not be executed. If, for example, 511 is
specified as the beginning word for writing,and two words of data are specified,
then 0512 will become the last word for writing data, and the command will not be
executed because SR 512 is beyond the writeable range.
