Note 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 2-7 CPU Bus Unit Setting Area Capacity for details.
The CJ-series system configuration can be expanded by using the following
serial communications ports.
• CPU Unit built-in ports × 2 (peripheral port and RS-232C port)
• Serial Communications Unit ports × 2 (RS-232C and RS-422A/485)
