(b) Flow of data sent from CPU No.1 to other CPU modules
<Parameter setting>
Refer to those related to the data communications of CPU No.1 ((a) to (c)) among the auto refresh setting
examples on Page 143, Section 6.1.2 (4) (a).
<Flow of data sent from CPU No.1 to other CPU modules>
• CPU No.1 writes data (CPU No.1 send data) in the devices set in the auto refresh parameter to its own
auto refresh area during END processing.
• CPU No.1 sends the data stored in its own auto refresh area to CPU No.2 and No.3 in each multiple CPU
high speed transmission cycle.
• CPU No.2 and No.3 transfer the data received from CPU No.1 to the devices set in the auto refresh
parameter (CPU No.1 receive area) during END processing.
