* 1 Necessity of setting : Required for multiple CPU systems. (Not operable without the setting)
: Can be set if necessary for the multiple CPU system. (Default values are applied if not
specified.)
: Set in the same way as single CPU system setting.
* 2 Same setting : Must be the same for all the CPU modules in the multiple CPU system.
: Must be the same for all of C Controller modules and programmable controller CPUs in
the multiple CPU system. (No setting available for Motion CPUs)
: Can be set individually for each CPU module of the multiple CPU system.
* 3 The system area can be set when "Advanced settings" is selected.
