3 WHEN COMMUNICATING USING THE QnA COMPATIBLE 3E/3C/4C FRAMES OR 4E FRAME
The examples shown in this section explain the control procedure for writing by
randomly designating multiple blocks, where one block consists of n points of
contiguous bit device memory (1 point = 16 bits) and word device memory (1
point = 1 word).
The data order and contents of the areas marked with " " in the control
procedure diagram differ depending on the module, communication frame and
format used.
Refer to the detailed information described in Section 3.1.
