CONCEPT OF MULTIPLE CPU SYSTEM
(2) Output (Y) loading
Whether to load outputs from output modules and intelligent function modules
controlled by other CPUs is determined by the "I/O sharing when using Multiple
CPUs" parameter in the <<Multiple CPU settings>> tab of C Controller setting utility.
(a) When "All CPU s can read all outputs" is selected
1) On/off data are loaded from output modules or intelligen function modules
controlled by other CPUs to the output (Y) of the host CPU by execution of a
bus interface function.
