Limitations The registered data is checked from the beginning and the data will be regis-
tered up to any errors. For example, if a command attempts to register 129
items, a frame length error (end code 18) will occur but the first 128 items will be
registered.
DM 6656 to DM 6999 do not exist, but an error will not occur if you try to register
these words.
Bits and words can be specified in any order and they will be registered in the
order that they were specified.
The data can be divided into multiple frames.
