Maximum number of
connectable Units
Total of 19 Units, including 9 Units on CPU Rack and 10 Units on one Expansion Rack.
(The built-in Ethernet port on the CPU Unit must be allocated to a slots 0, and is counted as one Unit.
Maximum number of
Expansion Racks
• CJ1M-CPU13-ETN:
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-CPU11-ETN/12-ETN:
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.
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 Units built-in timer.
I/O Interrupts: Interrupts from Interrupt Input Units.
Power OFF Interrupts (See note): Interrupts executed when the CPU Units power is turned OFF.
External I/O Interrupts: Interrupts from the Special I/O Units or CPU Bus Units.
Note: Not supported when the CJ1W-PD022 Power Supply Unit is mounted.
Calling subroutines from more than one
task
Supported (called global subroutines).
CIO (Core I/O) Area
I/O Area
2,560: CIO 000000 to CIO 015915 (160 words from CIO 0000 to CIO 0159)
The setting of the first word can be changed from the default (CIO 0000) so that
CIO 0000 to CIO 0999 can be used.
I/O bits are allocated to Basic I/O Units.
The CIO Area can be used as work
bits if the bits are not used as shown
here.
Link Area
3,200 (200 words): CIO 10000 to CIO 119915 (words CIO 1000 to CIO 1199)
Link bits are used for data links and are allocated to Units in Controller Link
Systems.
CPU Bus Unit Area
6,400 (400 words): CIO 150000 to CIO 189915 (words CIO 1500 to CIO 1899)
CPU Bus Unit bits store the operating status of CPU Bus Units. (25 words per
Unit, 16 Units max.)
Special I/O Unit Area
15,360 (960 words): CIO 200000 to CIO 295915 (words CIO 2000 to CIO
2959)
Special I/O Unit bits are allocated to Special I/O Units. (10 words per Unit, 96
Units max.)
Serial PLC Link Area
(CJ1M CPU Units
only)
1,440 (90 words): CIO 310000 to CIO 318915 (words CIO 3100 to CIO 3189)
DeviceNet Area
9,600 (600 words): CIO 320000 to CIO 379915 (words CIO 3200 to CIO 3799)
DeviceNet bits are allocated to Slaves for DeviceNet Unit remote I/O communi-
cations when the Master function is used with fixed allocations.
The following words are allocated to the Master function even when the
DeviceNet Unit is used as a Slave.
