22.4 Data Types
22.4 Data Types
The data types of a label are classified according to the bit length, processing method, and value range.
There are two data types.
• Primitive data type
• Generic data type (ANY type)
Primitive data type
The following table lists the data types included in the primitive data type.
*1 For the number of significant digits and input range of real number data input by the engineering tool, refer to the following.
 MELSEC iQ-R Programming Manual (CPU Module Instructions, Standard Functions/Function Blocks)
*2 The time type is used in a time data type function of standard functions. For standard functions, refer to the following.
