CHAPTER 6 COMMUNICATIONS AMONG CPU MODULES
6
6.1 Communications Using the CPU Shared Memory
6.1.2 Communications by auto refresh (using the multiple CPU high speed transmission area)
If "Start" and "End" fields are left blank in "Auto Refresh Setting", auto refresh is not performed. (Only the receive area can
be left blank.)
Ex.
When the auto refresh setting of CPU No.2 is left blank in "Flow of data sent from CPU No.3 to other CPU
modules" described on Page 146, Section 6.1.2 (4) (d)
CPU No.2 does not auto-refresh the data received from CPU No.3 to W40 to W5F.
For the flow of sending data from CPU No.3, refer to "Flow of sending data from CPU No.3 to other CPUs" on Page 146,
Section 6.1.2 (4) (d).
