3 COMMUNICATION BETWEEN THE PLC CPU AND THE MOTION CPU IN
THE MULTIPLE CPU SYSTEM
(3) Automatic refresh area
This area is used at the automatic refresh of the Multiple CPU system.
This area cannot be written using S. TO instruction/read using FROM instruction
of the PLC CPU and written using MULTW instruction/read using MULTR
instruction of the Motion CPU.
(4) User-defined area
This area is used for the communication among each CPU in the Multiple CPU
system using FROM/S. TO instructions and the intelligent function module
devices of the PLC CPU. (Among each CPU communicates using MULTR
instruction or MULTW instruction of the operating control program in the Motion
CPU.)
Refer to the Section 7.13.6 to 7.13.7, for MULTR instruction or MULTW
instruction.
After point set in the automatic refresh area is used.
(If the automatic refresh function is not executed, the area from 800H to FFFH
can be used as a user-defined area.)
