2. Check limitations of the power supply to ensure that it can handle the current requirements of your configured system.
The CJ1M-CPU13 and CJ1M-CPU23 support a maximum of 1 Expansion Rack with a total maximum of 20 Modules.
The CJ1M-CPU11, CJ1M-CPU12, CJ1M-CPU21 and CJ1M-CPU22 do not support Expansion Racks.

No backplane (Modules are joined together with interlocking connectors.)
DIN Track mounting (screw mounting is not possible.)
Per CPU or Expansion Rack: 10 Modules max. (i.e., Basic I/O Modules, Special I/O Modules, or
CPU Bus Modules)
Total per PLC: 10 Modules on CPU Rack and 10 Modules each on 3 Expansion Racks = 40
Modules max. (See Notes 1 and 2.)
3 max. (One CJ1 Series I/O Control Module is required on the CPU Rack, and one CJ1 Series I/O
Interface Module is required on each Expansion Rack.) (See Notes 1 and 2.)
288 (cyclic tasks: 32, interrupt tasks: 256)
With the CJ1G/H-CPUVVH and CJ1M-CPUVV, interrupt tasks can be defined as cyclic tasks to
create cyclic interrupt tasks.
Note: 1. Cyclic tasks are executed each cycle and are controlled with TKON(820) and
Scheduled Interrupts: Interrupts generated at a time scheduled by CPU’s built-in timer
I/O interrupt tasks: Interrupts from Interrupt Input Modules (CJ1G/H-CPUVVH and CJ1M-CPUVV)
Power OFF Interrupts: Interrupts executed when CPU’s power is turned OFF
External interrupt tasks: Interrupts from Special I/O Modules and CPU Bus Modules
(CJ1G/H-CPUVVH and CJ1M-CPUVV)
CJ1G/H-CPUVVH and CJ1M-CPUVV: supported using global subroutines
CJ1G-CPUVV: not supported
2. The following 4 types of interrupt tasks are supported:
TKOF(821) instructions.
Power OFF interrupt task: 1 max.
Scheduled interrupt tasks: 2 max.
I/O interrupt tasks: 32 max. (CJ1G/H-CPUVVH and CJ1M-CPUVV)
External interrupt tasks: 256 max. (CJ1G/H-CPUVVH and CJ1M-CPUVV)
