Maximum number of
connectable Units
• CJ1-H and CJ1 CPU Units:
Per CPU or Expansion Rack: 10 Units including Basic I/O Units,
Special I/O Units, and CPU Bus Units.
Total per PLC: 10 Units on CPU Rack and 10 Units each on 3
Expansion Racks = 40 Units total

Maximum number of
Expansion Racks
• CJ1-H and CJ1 CPU Units:
3 max. (An I/O Control Unit is required on the CPU Rack and an I/O
Interface Unit is required on each Expansion Rack.)
• CJ1M CPU Units (CPU 13/23 only):
1 max. (An I/O Control Unit is required on the CPU Rack and an I/O
Interface Unit is required on the Expansion Rack.)
• CJ1M CPU Units (CPU11/12/21/22):
Expansion is not possible.

sion Racks
Number of tasks 288 (cyclic tasks: 32, interrupt tasks: 256)
With CJ1-H or CJ1M CPU Units, interrupt tasks can be defined as
cyclic tasks called “extra cyclic tasks.” Including these, up to 288 cyclic
tasks can be used.
Note Cyclic tasks are executed each cycle and are controlled with
TKON(820) and TKOF(821) instructions.
Note The following 4 types of interrupt tasks are supported.
Power OFF interrupt tasks: 1 max.
Scheduled interrupt tasks: 2 max.
I/O interrupt tasks: 32 max.
External interrupt tasks: 256 max.

Interrupt types Scheduled Interrupts:
Interrupts generated at a time scheduled by the CPU Unit’s built-in
timer. (See note.)
I/O Interrupts:
Interrupts from Interrupt Input Units.
Power OFF Interrupts:
Interrupts executed when the CPU Unit’s power is turned OFF.
External I/O Interrupts:
Interrupts from the Special I/O Units or CPU Bus Units.
Note CJ1-H and CJ1 CPU Units: Scheduled interrupt time interval is
either 1 ms to 9,999 ms or 10 ms to 99,990 ms, in units of 1 ms
or 10 ms.
CJ1M CPU Units: In addition to the above, a scheduled inter-
rupt time interval of 0.5 ms to 999.9 ms, in units of 0.1 ms, is
also possible.
