(2) Loading output (Y)
The "I/O sharing when using Multiple CPUs" setting in the PLC parameter's Multiple CPU settings determines
whether output can be loaded from output modules and intelligent function modules being controlled by other
CPUs.
(a) When "All CPUs can read all outputs" has been set
1) Loads to the host CPU's output (Y) the ON/OFF data that is output to the output module and intelligent
function modules being controlled by the other CPUs, by performing output refresh before a sequence
program operation starts.
