The PROFIBUS Master Unit can be mounted to any slot in either a CJ-series
CPU Rack, or a CJ-series Expansion CPU Rack. The CJ-series PLC supports
up to 4 Expansion CPU Racks, in addition to the CPU rack.
The number of slots to which PROFIBUS Master Unit can be mounted in any
of the positions shown below using the sliders on the top and bottom of the
Unit. Up to 16 PROFIBUS Master Units can be mounted to a single PLC. If it
is mounted in combination with other CPU Bus Units (e.g., Ethernet Units),
the maximum total number of CPU Bus Units that can be mounted is 16.
