Maximum numberof connectableUnits		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 totalCJ1M CPU Units:Total of 20 Units in the System, including 10 Units on CPU Rack and 10 Units on one Expansion Rack.
Maximum numberof ExpansionRacks		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.
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 1.Cyclic tasks are executed each cycle and are controlled with TKON(820) and TKOF(821) instructions.Note 2.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. 1)I/O Interrupts: Interrupts from Interrupt Input Units.Power OFF Interrupts (See note 2.): 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 1.CJ1-H and CJ1 CPU Units: Scheduled interrupt time interval is either 1 ms to 9,999 ms (in increments of 1 ms) or 10 ms to99,990 ms (in increments of 10 ms) CJ1-H-R CPU Units: Scheduled interrupt time interval is 0.2 ms to 999.9 ms (in increments of 0.1 ms), 1 ms to 9,999 ms (in increments of 1 ms), or 10 ms to 99,990 ms (in increments of 10 ms)CJ1M CPU Units: Scheduled interrupt time interval is 0.5 ms to 999.9 ms (in increments of 0.1 ms), 1 ms to 9,999 ms (in increments of 1 ms), or 10 ms to 99,990 ms (in increments of 10 ms)Note 2.Not supported when the CJ1W-PD022 Power Supply Unit is mounted.
Callingsubroutines frommore than one task		CJ1-H CPU Units: Supported (called "global subroutines").CJ1 CPU Units: Not supported.
Function blocks(CPU Unit withunit version 3.0or later only)		Languages in function block definitions: ladder programming, structured text
