The response data is set in the same way, starting from the word specified for
CMND(490) operand D (first response word) and continuing with words with
higher addresses in I/O memory in the response block format.
byte) units, such as word data and ERROR CLEAR codes, is specified from
low to high (U) bytes in command block format. For example, to specify word
data 1234 hex, specify 34 hex and then 12 hex. To specify the double word
data 12345678 hex, specify 78 hex, 56 hex, 34 hex, and then 12 hex. The
command blocks are shown in the following diagram.
Similarly, when the additional status data and service response data in the
response block is in word (2-byte) or double-word (4-byte) units, such as word
