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