•
Project view  "Parameter"  "CCPU Parameter"  <<I/O assignment settings>> 
"Base Setting"
When "Auto" is selected in the Base Mode, the number of points for the mounted slot becomes valid.
When "Detail" is selected in the Base Mode, the number of slots can be set for each base unit.
● In auto mode, when any extension base unit number is skipped at the setting using the base number setting connector,
an empty extension base unit cannot be reserved. To reserve empty extension base units for future extension, select
detail mode.
● In detail mode, set the number of slots to all base units used. Failure to do so may result in incorrect I/O assignment
setting.
