A total of up to 16 Units, including all other
CPU Bus Units. No
restrictions on the mounting location.
However, if an external interrupt task is used,
the Unit must be mounted in one of the
following slots on the CPU Rack.
CJ2H-CPU6[]-EIP CPU Unit: Slots 0 to 3
CJ2H-CPU6[], CJ2M-CPU[][] or CJ1G/H-
CPU[][]H CPU Unit: Slots 0 to 4
CJ1M-CPU[][] CPU Unit: Slots 0 to 2
External interrupt tasks will not be started if
the Unit is mounted to any other slot.

A total of up to 16 Units, including all other CPU Bus Units.
No restrictions on the mounting location.
