Programming Languages

Ladder Logic (LD),

Sequential Function Charts (SFC),

Structured Text (ST), and

Instruction Lists (IL)

Function

Blocks

Maximum number of definitions

2,048

Maximum number of instances

2,048

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.

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) *1

• UDINT BCD (two-word unsigned BCD) *1

• ULINT BCD (four-word unsigned BCD) *1

• REAL (two-word floating-point)

• LREAL (four-word floating-point)

• CHANNEL (word) *1

• NUMBER (constant or number) *1

• WORD (one-word hexadecimal)

• DWORD (two-word hexadecimal)

• LWORD (four-word hexadecimal)

• STRING (1 to 255 ASCII characters)

• TIMER (timer) *2

• COUNTER (counter) *2

• User defined data types (data structures) *3

*1. Cannot be used in Function blocks

*2. Can be used only in Function blocks

*3. Supported only when CX-Programmer version 9.0 or later is used

Maximum Size of Symbol

32k words

Array Symbols (Array Variables)

One-dimensional arrays

Number of Array Elements

32,000 elements max.

Number of Registrable Network

Symbols (Tags)

20,000 max.

Length of Network Symbol (Tag)

Name

255 bytes max.

Encoding of Network Symbols

Memory Capacity

8,000 words

16,000 words

32,000 words

(The EM Area can be specified from the CX-Programmer to use up to 32K words multiplied by the number of

banks supported by the CPU Unit model.)

Number of Samplings

Bits = 31, one-word data =16, two-word data = 8, four-word data = 4

Sampling Cycle

1 to 2,550 ms (Unit: 1 ms)

Trigger Conditions

ON/OFF of specified bit

Data comparison of specified word

Data size: 1 word, 2 words, 4 words

Comparison Method: Equals (=), Greater Than (>), Greater Than or Equals (

≥), Less Than (<), Less Than or

Equals (

≤), Not Equal (≠)

Delay Value

−32,768 to +32,767 ms

File Memory

Memory Card (128, 256, or 512 Mbytes) (Use the Memory Cards provided by OMRON.)

EM file memory (Part of the EM Area can be converted for use as file memory.)
