Tasks

Type of Tasks

Cyclic tasks

Interrupt tasks (Power OFF interrupt tasks, scheduled interrupt tasks, I/O interrupt tasks, and external interrupt

tasks)

Number of Tasks

Cyclic tasks: 128

Interrupt tasks: 256

(Interrupt tasks can be defined as cyclic tasks to create extra cyclic tasks. Therefore, the total number of cyclic

tasks is actually 384 max.)

Symbols

(Variables)

Type of Symbols

• Local symbols: Can be used only within a single task in the PLC.

• Global symbols: Can be used in all tasks in the PLC.

• Network symbols (tags)*: I/O memory in the CPU Unit can be externally accessed using symbols,

depending on parameter settings.

* Supported only by the CJ2M-CPU3@.

Data Type of Symbols

• BOOL (bit)

• UINT (one-word unsigned binary)

• UDINT (two-word unsigned binary)

• ULINT (four-word unsigned binary)

• INT (one-word signed binary)

• DINT (two-word signed binary)

• LINT (four-word signed binary)

• UINT BCD (one-word unsigned BCD) *2

• UDINT BCD (two-word unsigned BCD) *2

• ULINT BCD (four-word unsigned BCD) *2

• REAL (two-word floating-point)

• LREAL (four-word floating-point)

• CHANNEL (word) *2

• NUMBER (constant or number) *2

• WORD (one-word hexadecimal)

• DWORD (two-word hexadecimal)

• LWORD (four-word hexadecimal)

• STRING (1 to 255 ASCII characters)

• TIMER (timer) *3

• COUNTER (counter) *3

• User defined data types (data structures)
