z CJ-series CPU Bus Units
*1 Slave I/O are allocated in DeviceNet Area (CIO 3200 to CIO 3799).
*2 Some CJ-series CPU Bus Units are allocated words in the CPU Bus Unit Setting Area. The system must be designed so
that the number of words allocated in the CPU Bus Unit Setting Area does not exceed its capacity. Refer to 4-6-2 Proce-
dure for Setting CPU Bus Unit Setup Area in the CJ2 CPU Unit Software User’s Manual (Cat. No. W473).
*3 Increases by 0.15 A/Unit when an NT-AL001 RS-232C/RS-422A Link Adapter is used. Increases by 0.04 A/Unit when a
CJ1W-CIF11 RS-422A Conversion Unit is used.
*4 When mounting to a CJ-series CPU Rack or a CJ-series Expansion Rack, one of these Units uses the space of three
Units.
*5 Includes the weight of accessory connectors.
*6 Use version 2 or higher of the SYSMAC SPU Unit with a CJ2 CPU Unit.
